Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. However, the scope of the invention is not limited to the illustrated examples.
FIG. 1 is a block diagram showing a schematic configuration of an image display apparatus 100 according to an embodiment to which the present invention is applied.

The image display apparatus 100 according to the present embodiment specifies an operation locus L formed by connecting a plurality of operation points input based on a predetermined operation of the touch panel 2a by the user in the image display area of the display panel 1a. Then, the image display apparatus 100 detects a face area that overlaps with the operation locus L from the display image, and sequentially inputs a plurality of operation points that constitute the operation locus L that overlaps with the face area based on a predetermined operation of the touch panel 2a. The display magnification of the face area is set based on the speed.
Specifically, the image display device 100 is, for example, a digital photo frame installed on a table, and as illustrated in FIG. 1, the display unit 1, the operation input unit 2, the operation locus specifying unit 3, An image processing unit 4, a memory 5, an image recording unit 6, and a central control unit 7 are provided.

The display unit 1 includes a display panel 1a and a display control unit 1b.
The display panel 1a constitutes display means for displaying an image (for example, the image P1 or the like; see FIG. 4). Examples of the display panel 1a include a liquid crystal display panel and an organic EL display panel. However, the display panel 1a is an example and is not limited thereto.
The display control unit 1b displays the image data read from the image recording unit 6 and decoded by the image processing unit 4 on the display screen of the display panel 1a.

  Further, the display control unit 1b performs a face region (for example, face regions f1, f2, f3, etc.) by a specific region detection unit 4a (described later) of the image processing unit 4 in an image reproduction process (described later); FIG. When FIG. 5C is sequentially detected, the plurality of face regions are displayed on the display screen of the display panel 1a in the order of detection. At this time, the display control unit 1b displays each face area in a display mode according to the reproduction display content of each face area set by the reproduction display content setting unit 4b (described later). That is, the display control unit 1b enlarges the face area sequentially detected by the specific area detection unit 4a according to the display magnification of the face area set by the display magnification setting unit 4d (described later) of the reproduction display content setting unit 4b. . Further, the display control unit 1b displays the face areas sequentially detected by the specific area detection unit 4a on the display screen of the display panel 1a with the display time of the face area set by the display time setting unit 4e (described later). .

  The operation input unit 2 has an operation unit constituted by, for example, data input keys for inputting numerical values, characters, etc., up / down / left / right movement keys for performing data selection, feeding operations, etc. Then, a predetermined operation signal is output to the central control unit 7 in accordance with the operation of these operation units.

Further, the operation input unit 2 has a touch panel 2 a provided integrally with the display panel 1 a of the display unit 1.
The touch panel 2a detects the contact position of a user's finger (hand), touch pen, or the like that directly or indirectly contacts the display screen forming the image display area of the display panel 1a (see FIG. 4). That is, the touch panel 2a is provided, for example, on the display screen or inside the display screen, and the touch position of the touch position on the display screen can be determined by various methods such as a resistive film method, an ultrasonic surface acoustic wave method, and a capacitance method. XY coordinates are detected. Then, the touch panel 2 a outputs a position signal related to the XY coordinates of the contact position to the central control unit 7.
In addition, the detection accuracy of the contact position on the display screen by the touch panel 2a can be arbitrarily arbitrarily changed. For example, one pixel may be strictly set as the contact position, or within a predetermined range centered on one pixel. A plurality of pixels may be used as the contact position.

The operation locus specifying unit 3 specifies an operation locus L (see FIG. 4) input based on a predetermined drawing operation of the operation input unit 2 by the user.
That is, when the position signal related to the XY coordinates of the contact position continuously detected by the touch panel 2a of the operation input unit 2 is output from the central control unit 7 and input, the operation locus specifying unit 3 Each contact position is specified as each operation point in the image display area of the display panel 1a. And a locus | trajectory specific | specification part specifies the operation locus | trajectory L (refer FIG. 4) corresponding to drawing operation by a user by connecting the specified several operation points.
In FIG. 4, an example of the operation locus L is schematically shown on the image display area of the display panel 1a. However, whether or not the operation locus L is displayed so as to be visible can be arbitrarily changed as appropriate. Is possible.
Here, the operation trajectory specifying unit 3 specifies an operation trajectory L formed by connecting a plurality of operation points input based on a predetermined operation of the operation input unit 2 by the user in the image display area of the display panel 1a. Means.

The image processing unit 4 decodes still image data and moving image data of the display image read from the image recording unit 6 according to a predetermined encoding method (for example, JPEG format, motion JPEG format, MPEG format, etc.). To the display control unit 1b.
Further, the image processing unit 4 detects a face area related to the slide show reproduction, sets the reproduction display contents of the face area, and the like in the image reproduction process. Specifically, the image processing unit 4 includes a specific area detection unit 4a and a reproduction display content setting unit 4b.

The specific area detection unit 4a detects a specific area (for example, a human face area) from an image (for example, the image P1 or the like) displayed on the display panel 1a.
That is, the specific area detection unit 4a overlaps the operation locus L specified by the operation locus specification unit 3 with respect to the still image data of the display image by using a predetermined image recognition technique such as face detection processing, for example. Detect specific areas. Specifically, the specific area detection unit 4a sets a search area for a face image based on a portion (for example, the center) that overlaps the operation locus L specified by the operation locus specification unit 3 in the display image. In the search area, a part having the highest similarity to predetermined face detection information is detected as a face area.
In addition, as the operation locus L specified by the operation locus specifying unit 3 becomes longer in accordance with a series of drawing operations by the user, the specific area detection unit 4a sequentially adds face areas that sequentially overlap the operation locus L from the display image. I will detect it. For example, the specific area detection unit 4a sequentially detects the face area f1, the face area f2, the face area f3,... As the face areas in the display image (see FIGS. 5A to 5C). .
Here, the image data of the display image to be processed by the specific area detection unit 4a may be, for example, high-resolution image data for recording read from the image recording unit 6, or high processing speed. For example, the image data may be image data having a lower resolution than the image data for recording generated for detecting the specific area.

In addition, although the human face area is illustrated as the specific area, it is an example and is not limited thereto, and can be arbitrarily changed as appropriate. For example, even a main area such as an object, a plant, or an animal may be used. good.
In addition, as an image recognition technique, for example, edge detection processing, feature extraction processing, or the like may be applied, or the outline of a specific area may be extracted from the continuity of changes in color or brightness, or specified in advance. The type of area (for example, a human face area or main area) may be specified, and a contour may be extracted by comparison with the characteristic information of the specific area. Note that the face detection process, the edge detection process, and the feature extraction process are known techniques, and thus detailed description thereof is omitted here.
As described above, the specific area detecting unit 4a constitutes a detecting unit that detects a face area (specific area) overlapping with the operation locus L specified by the operation locus specifying unit 3 from the image displayed on the display panel 1a. .

  The reproduction display content setting unit 4b uses the speed v for sequentially inputting a plurality of operation points constituting the operation locus L overlapping the face area based on a predetermined operation of the operation input unit 2 as a reference image (for example, the image P1). And the like, for example, the reproduction display contents of the face area (for example, face areas f1, f2, f3, etc.) detected from the face area are set. Specifically, the reproduction display content setting unit 4b includes an operation instruction speed calculation unit 4c, a display magnification setting unit 4d, and a display time setting unit 4e.

The operation instruction speed calculating unit 4c sequentially inputs a plurality of operation points constituting the operation locus L based on a predetermined operation of the operation input unit 2 (hereinafter referred to as “operation instruction speed v of a plurality of operation points”). Say).
Here, the operation instruction speed v of the plurality of operation points overlaps with one specific area (for example, a face area) of the display image in the image display area of the display panel 1a by a predetermined operation of the operation input unit 2 by the user. This is a speed at which a plurality of operation points constituting the operation locus L are sequentially input. That is, when the operation locus L is input by the user's touch operation (drawing operation) on the touch panel 2a of the operation input unit 2, the display displayed in the image display area of the display panel 1a based on the touch operation of the touch panel 2a by the user. A user's finger, a touch pen, or the like passes over one face area (specific area) of the image. As a result, a plurality of operation points constituting the operation locus L that overlaps with the one face area are sequentially input, and the speed at which the plurality of operation points are sequentially input is set to the operation instruction speed v of the plurality of operation points. Become.
Then, the operation instruction speed calculation unit 4c, for example, calculates the distance (for example, the number of pixels) of the operation locus L that overlaps one face region (specific region) of the display image to the operation locus L for one face region. The operation instruction speed v for a plurality of operation points is calculated by dividing by the time from when the first operation point to be configured begins to overlap until the overlap with the last operation point ends.
The method for calculating the operation instruction speed v at the plurality of operation points described above is an example and is not limited to this. For example, the arithmetic expression used can be arbitrarily changed as appropriate.

The display magnification setting unit 4d sets the display magnification of the face area detected from the display image (for example, the image P1).
That is, the display magnification setting unit 4d uses the operation instruction speed v of a plurality of operation points constituting the operation locus L that overlaps the face area calculated by the operation instruction speed calculation unit 4c as a reference, and the display control unit 1b for the face area. Sets the display magnification for slide show playback by. Specifically, the display magnification setting unit 4d uses the display content setting table T (see FIG. 2) to sequentially input a plurality of operation points related to the face area instruction based on the touch operation of the touch panel 2a. The display magnification of the face area is set so as to be inversely proportional to the operation instruction speed v (the operation instruction speed v of the user's finger or touch pen). That is, the display magnification setting unit 4d sets the display magnification of the face area to be relatively smaller as the operation instruction speed v of the plurality of operation points is faster. On the other hand, the display magnification setting unit 4d sets the display magnification of the face area to be relatively larger as the operation instruction speed v of the plurality of operation points is slower. For example, the display magnification setting unit 4d refers to the display content setting table T and operates the operation instruction speed v (for example, “v2 ≦ v <v1” of the face area (for example, the face area f3; see FIG. 5C)). ”Etc.) is set in accordance with the display magnification of the face area (for example,“ 2 × ”, etc.).
The display magnification setting unit 4d displays each face area according to the operation instruction speed v of each of the plurality of face areas when the face area (specific area) is sequentially detected by the specific area detection unit 4a. Set the magnification sequentially. In this case, the order of setting the display magnification of the face area may be the same as or different from the order of detection of the face area by the specific area detection unit 4a.

The display magnification of the face region (specific region) is a magnification for enlarging the specific region detected from the display image (original image) with respect to the dimension of the original image of the specific region. Note that the display magnification can be any value as long as it is “0” or more. For example, the display magnification does not have to be less than “1 time (a specific area of the original image and this magnification)”.
Here, the display magnification setting unit 4d determines a speed v for sequentially inputting a plurality of operation points constituting the operation locus L overlapping the face area (specific area) based on a predetermined operation of the operation input unit 2 as an operation instruction speed v. ), Setting means for setting the display magnification of the face area on the basis of the operation instruction speed v is configured.

The display time setting unit 4e sets the display time of the face area detected from the display image (for example, the image P1).
That is, the display time setting unit 4e uses the operation instruction speed v of a plurality of operation points constituting the operation locus L that overlaps the face area calculated by the operation instruction speed calculation unit 4c as a reference, and the face area display control unit 1b. Sets the display time for slide show playback by. Specifically, the display time setting unit 4e uses the display content setting table T (see FIG. 2) to sequentially input a plurality of operation points related to the face area instruction based on the touch operation of the touch panel 2a. The display time of the face area is set so as to be directly proportional to the operation instruction speed v (the operation instruction speed v of the user's finger or touch pen). That is, the display time setting unit 4e sets the display time of the face area to be relatively shorter as the operation instruction speed v of the plurality of operation points is faster. On the other hand, the display time setting unit 4e sets the display time of the face area to be relatively longer as the operation instruction speed v of the plurality of operation points is slower. For example, the display time setting unit 4e refers to the display content setting table T and operates the operation instruction speed v (for example, “v2 ≦ v <v1” of the face area (for example, the face area f3; see FIG. 5C)). The display time of the face area (for example, “2 seconds”, etc.) is set according to “.
In addition, when the specific area detection unit 4a sequentially detects the face area (specific area), the display time setting unit 4e displays each face area according to the operation instruction speed v of each of the plurality of face areas. Set the time sequentially. In this case, the order of setting the display time of the face area may be the same as or different from the order of detection of the face area by the specific area detection unit 4a.

The display time of the face area (specific area) is the time from when the specific area is displayed on the display screen until the display is finished. Note that when a switching effect (for example, fade-in, fade-out, wipe, etc.) is applied when switching the face area display ON / OFF, the time during which the switching effect is being executed may be included. It may be removed.
Here, the display time setting unit 4e sequentially inputs a plurality of operation points constituting the operation locus L that overlaps the face region (specific region) based on a predetermined operation of the operation input unit 2 (speed v (a plurality of operation points). Functioning as a setting means for setting the display time of the face area by the display control unit 1b.

As shown in FIG. 2, the display content setting table T is a face area having a speed v for sequentially inputting a plurality of operation points constituting an operation locus L overlapping the face area based on a predetermined operation of the operation input unit 2. The operation instruction speed v, the display magnification of the face area, and the display time of the face area are stored in association with each other. Here, the operation instruction speed v of the face area and the display magnification of the face area are inversely proportional, and the operation instruction speed v of the face area and the display time of the face area are directly proportional. ing.
Specifically, for example, the operation instruction speed v (“v1 ≦ v”) of the face area which is a speed equal to or higher than the speed v1, the display magnification “1 ×” of the face area, and the display time “1 second” of the face area Are associated with each other. Also, for example, the operation instruction speed v (“v2 ≦ v <v1”) of the face area which is slower than the speed v1 and higher than the speed v2, the display magnification “2 ×” of the face area, and the display of the face area The time “2 seconds” is associated with each other. Also, for example, the face area operation instruction speed v (“v3 ≦ v <v2”) that is slower than the speed v2 and higher than the speed v3, the face area display magnification “3 ×”, and the display of the face area The time “3 seconds” is associated with each other. Similarly, the operation instruction speed v of the face area slower than the speed v3 is also stored in association with each other until the speed becomes “0”, but the illustration is omitted.
The correspondence relationship between the operation instruction speed v of the face area in the display content setting table T, the display magnification of the face area, and the display time of the face area is an example, and is not limited thereto. It can be arbitrarily changed as appropriate.

  The memory 5 is composed of, for example, a DRAM (Dynamic Random Access Memory) or the like, and temporarily stores data processed by the image processing unit 4 or the central control unit 7.

  The image recording unit 6 is configured by, for example, a nonvolatile memory (flash memory). The image recording unit 6 stores still images and moving images displayed on the display unit 1, and still image data encoded by a predetermined encoding method and moving image data including a plurality of image frames. Record.

  The central control unit 7 controls each unit of the image display device 100. Specifically, although not shown, the central control unit 7 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and a ROM (Read Only Memory), and includes various processing programs (for the image display device 100). Various control operations are performed according to (not shown).

Next, image reproduction processing by the image display device 100 will be described with reference to FIGS. 3 and 4 and FIGS. 5 (a) to 5 (c).
FIG. 3 is a flowchart illustrating an example of an operation related to the image reproduction process.
In the following description, it is assumed that an image P1 in which a display area includes a face area as a specific area is used.

As shown in FIG. 3, first, based on a predetermined operation of the operation input unit 2 by the user, a desired image P1 to be displayed among a plurality of images recorded in the image recording unit 6 (see FIG. 4). Is selected and designated, the image processing unit 4 reads the image data of the image P1 from the image recording unit 6 (step S1). Then, the image processing unit 4 decodes the read image data according to a corresponding predetermined encoding method (for example, JPEG format) and outputs the decoded image data to the display control unit 1b.
Based on the image data decoded by the image processing unit 4, the display control unit 1b displays the image P1 related to the image data on the display screen of the display panel 1a (step S2).

Next, the central control unit 7 determines whether or not there is an instruction to input an operation point in the image display area of the display panel 1a within a predetermined period (step S3). Specifically, the central control unit 7 detects the contact of the user's finger (hand), touch pen, or the like with respect to the display screen of the display panel 1a by the touch panel 2a, and the XY coordinates of the contact position output from the touch panel 2a. It is determined whether or not there is an input of an operation point by the user depending on whether or not a position signal related to is input.
Here, if it is determined that there is no operation point input by the user (step S3; NO), the central control unit 7 returns the process to step S3, and repeatedly executes the above determination process at a predetermined timing (step S3). S3).

  On the other hand, if it is determined in step S3 that there is an operation point input by the user (step S3; YES), the operation locus specifying unit 3 displays an operation locus L corresponding to the drawing operation by the user from a plurality of operation points. (Step S4; refer to FIG. 4). Specifically, the operation locus specifying unit 3 displays each of the touch positions of the touch panel 2a on the display panel 1a based on the position signal related to the XY coordinates of the touch position of the touch panel 2a output and input from the central control unit 7. Are specified as operation points in the image display area, and the operation locus L corresponding to the drawing operation by the user is specified by connecting the plurality of operation points.

Subsequently, the image processing unit 4 determines whether or not the operation track L is specified by the operation track specifying unit 3 (step S5).
Here, when it is determined that the operation locus L is not identified by the operation locus identifying unit 3 (step S5; NO), the central control unit 7 returns the process to step S3. That is, the user's finger (hand), touch pen, or the like is in contact with the display screen of the display panel 1a, and a plurality of contact positions (operation points) with respect to the touch panel 2a are not detected. Since L cannot be specified, the central control unit 7 accepts an input instruction for the next operation point in the image display area of the display panel 1a in step S3.

  And when it determines with the operation locus | trajectory L having been specified by the operation locus | trajectory identification part 3 in step S5 (step S5; YES), the specific area | region detection part 4a will be from the image P1 currently displayed on the display panel 1a. A face area overlapping the operation locus L is detected using a predetermined image recognition technique such as face detection processing (step S6). Specifically, the specific area detection unit 4a sets a search area for a face image based on a portion overlapping the operation locus L in the displayed image P1, and then performs a predetermined face detection in the search area. A part having the highest similarity to information is detected as a face area.

  In the face area detection process, after the operation locus L is specified, the face region overlapping the operation locus L is detected from the display image P1, but the present invention is not limited to this. The face detection process for P1 may be performed to detect all face areas in the display image P1, and after the operation locus L is specified, only the face region that overlaps the operation locus L may be specified.

Subsequently, the image processing unit 4 determines whether or not a face region is detected by the specific region detection unit 4a (step S7).
Here, if it is determined that the face area is not detected by the specific area detection unit 4a (step S7; NO), the central control unit 7 returns the process to step S6, and the specific area detection unit as described above. 4a detects a face area overlapping with the operation locus L from the image P1 displayed on the display panel 1a (step S6).
On the other hand, when it is determined in step S7 that the specific area detection unit 4a has detected the face area (step S7; YES), the operation instruction speed calculation unit 4c of the reproduction display content setting unit 4b detects the detected face area. The operation instruction speed v for sequentially inputting the plurality of operation points according to the above, that is, the plurality of operation points constituting the operation locus L overlapping with the face area, based on the touch operation of the touch panel 2a is calculated according to a predetermined arithmetic expression (Step S1). S8).

  Next, the display magnification setting unit 4d of the reproduction display content setting unit 4b refers to the display content setting table T and relates to the face area (for example, the face area f1) calculated by the operation instruction speed calculation unit 4c. The display magnification (for example, “3 times”, etc.) of the face area is set according to the operation instruction speed v (for example, “v3 ≦ v <v2”, etc.) at a plurality of operation points (step S9). In addition to setting the display magnification of the face area, the display time setting unit 4e refers to the display content setting table T and instructs operation of a plurality of operation points related to the face area calculated by the operation instruction speed calculation unit 4c. The display time of the face area (for example, “3 seconds”) is set according to the speed v.

Subsequently, the central control unit 7 determines whether or not there is an instruction to input an operation point in the image display area of the display panel 1a by the user within a predetermined period (step S10). The determination process here is substantially the same as the determination process in step S3, and a detailed description thereof will be omitted.
Here, if it is determined that there is an input of an operation point by the user (step S3; YES), the central control unit 7 returns the process to step S4, and the operation locus specifying unit 3 is operated by the user from a plurality of operation points. The operation locus L corresponding to the drawing operation is specified (step S4).
That is, since the user's finger (hand), touch pen, or the like that is in contact with the display screen of the display panel 1a is moving in a predetermined direction and performing a drawing operation, the processes in and after step S4 are sequentially performed. Go. If a new face area (for example, face area f2 or face area f3) is detected in step S7, the operation instruction speed calculation unit 4c detects in step S8 as described above. The operation instruction speed v of the plurality of operation points related to the face area thus calculated is calculated according to a predetermined arithmetic expression. Thereafter, in the same manner as described above, in step S9, the display magnification setting unit 4d refers to the display content setting table T, and the face area (for example, the face area f2) calculated by the operation instruction speed calculation unit 4c. The display magnification (for example, “1 ×”, etc.) of the face area is set according to the operation instruction speed v (for example, “v1 ≦ v”, etc.) of the plurality of operation points. In addition to setting the display magnification of the face area, the display time setting unit 4e refers to the display content setting table T and instructs operation of a plurality of operation points related to the face area calculated by the operation instruction speed calculation unit 4c. The display time of the face area (for example, “1 second”) is set according to the speed v.

On the other hand, if it is determined in step S10 that there is no input of an operation point by the user (step S3; NO), the display control unit 1b stops displaying the image P1 displayed on the display screen of the display panel 1a. At the same time, the face area detected by the specific area detecting unit 4a is reproduced as a slide show in a predetermined display mode. That is, the display control unit 1b reproduces and displays the face areas sequentially detected by the specific area detection unit 4a in the order of detection of the face areas (for example, the order of the face area f1, the face area f2, and the face area f3). The display area is enlarged according to the display magnification of the face area set by the display magnification setting section 4d of the setting section 4b, and is reproduced and displayed on the display screen of the display panel 1a with the display time of the face area set by the display time setting section 4e. (Step S11).
Thereby, the image reproduction process is terminated.

As described above, according to the image display device 100 of the present embodiment, the operation locus specifying unit 3 displays each of the plurality of contact positions detected continuously based on a predetermined operation of the touch panel 2a by the user on the display panel. The operation locus L is specified by connecting each of the plurality of operation points in the image display area 1a. Then, the specific area detection unit 4a detects a specific area (for example, a face area) that overlaps the operation locus L drawn based on a predetermined operation of the touch panel 2a by the user from the image displayed on the display screen of the display panel 1a. To detect. Then, the reproduction display content setting unit 4b uses the operation instruction speed v to sequentially input a plurality of operation points constituting the operation locus L overlapping the detected specific area based on a predetermined operation of the touch panel 2a as a reference to the specific area. Set playback display contents such as display magnification and display time. Therefore, simply by operating the touch panel 2a at a predetermined speed, the user can easily set the reproduction display content of the specific area detected from the image according to the operation speed of the touch panel 2a.
Specifically, the display magnification of the face area at the time of image reproduction is set based on the operation instruction speed v of a plurality of operation points, and more specifically, the display magnification of the face area is set as the instruction of the face area. It is set to be inversely proportional to the operation instruction speed v of the plurality of operation points. Therefore, the face area (for example, the face area f1; see FIG. 5A) on which the touch panel 2a is slowly instructed by the user can be enlarged and displayed relatively large. On the other hand, the face area (for example, face area f2; see FIG. 5B) on which the touch panel 2a is quickly instructed by the user can be enlarged and displayed relatively small. Furthermore, the display time of the face area at the time of image reproduction is set on the basis of the operation instruction speed v of the plurality of operation points, and more specifically, the display time of the face area is set to a plurality of points related to the instruction of the face area. Set to be directly proportional to the operation command speed v at the operating point. Therefore, the face area (for example, the face area f1; see FIG. 5A) in which the touch panel 2a is slowly operated by the user is displayed for a relatively long time as shown in the display content setting table T in FIG. Can be made. On the other hand, the face area (for example, face area f2; see FIG. 5B) in which the touch panel 2a is quickly instructed by the user has a relatively short time as shown in the display content setting table T in FIG. Can be displayed.
Thereby, the intuitive operation of the touch panel 2a by the user can be reflected in the reproduction display content of the face area, and the face can be changed by changing the operation speed of the touch panel 2a (operation instruction speed v of a plurality of operation points). The reproduction display mode of the area can be varied and varied.

  Further, as the operation locus L drawn based on a predetermined operation of the touch panel 2a by the user becomes longer, face areas sequentially overlapping with the operation locus L are sequentially detected from the display image, and the detected face areas are sequentially detected. Since it can be displayed in the order of detection according to the reproduction display contents such as the display magnification and display time of the face area, the reproduction display contents of a plurality of face areas in the image are set only by the user performing a predetermined operation on the touch panel 2a. Therefore, it is possible to realize the easy-to-use slide show reproduction in which the setting of the reproduction display contents of the plurality of face areas is simple and the reproduction display modes of the face areas are varied.

The present invention is not limited to the above-described embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the operation locus L is instructed to be input using the touch panel 2a of the operation input unit 2. However, the method for inputting the operation locus L is an example, and is not limited to this, and can be arbitrarily changed as appropriate. is there. For example, by using an up / down / left / right movement key (not shown) of the operation input unit 2, a predetermined icon (for example, a pointer) for drawing the operation locus L displayed in the image display area is moved on the XY plane. Thus, the input of the operation locus L may be instructed.
Here, based on a predetermined operation of the up / down / left / right movement key by the user, a predetermined icon for drawing the operation locus L displayed in the image display area of the display panel 1a is displayed on the display image displayed in the image display area. On one face area (specific area). As a result, a plurality of operation points constituting the operation locus L that overlaps with the one face area are sequentially input, and the speed at which the plurality of operation points are sequentially input is set to the operation instruction speed v of the plurality of operation points. Become.

In the above embodiment, the display magnification and display time of the face area are exemplified as the reproduction display contents of the face area. However, the display magnification and display time of these face areas are examples of the reproduction display contents. The present invention is not limited to this, and can be arbitrarily changed as appropriate. For example, as a playback display content of the face area, a switching effect (for example, fade-in, fade-out, wipe, etc.) when switching the face area display ON / OFF, and a color tone of the face area (for example, color, monochrome, sepia, etc.) ), BGM (Back Ground Music), etc. may be set.
Furthermore, although the display time of the face area is set together with the display magnification of the face area, it is not always necessary to set the display time of the face area.

  Further, in the above embodiment, the setting of playback display contents such as the display magnification and display time of the face area is performed with reference to the operation instruction speeds v of the plurality of operation points constituting the operation locus L overlapping the face area. However, the present invention is not limited to this. For example, the shape of each operation track L itself in the image display area of the display panel 1a or the entire shape connecting all the operation tracks L is reproduced and displayed in the face area. You may make it reflect in. That is, a two-dimensional shape of each operation locus L itself or a two-dimensional shape connecting all the operation locus L is used as a gesture command, and the face area is reproduced and displayed in a specific reproduction display mode associated with the gesture command. May be.

Furthermore, in the above embodiment, the display magnification and display time of the face area are set using the display content setting table T. However, the setting method is not limited to this. For example, The calculation may be performed by a predetermined calculation using the calculation processing circuit of the image processing unit 4.
The display magnification setting unit 4d sets the display magnification of the face area (specific area) so as to be inversely proportional to the operation instruction speed v of the plurality of operation points, but is not limited thereto. Alternatively, it may be set to be directly proportional to the operation instruction speed v at a plurality of operation points.
Furthermore, the display time setting unit 4e sets the display time of the face area (specific area) to be directly proportional to the operation instruction speed v of the face area, but is not limited to this. It may be set so as to be inversely proportional to the operation instruction speed v at the operation point.

Further, in the above embodiment, in the image reproduction process, after setting the reproduction display contents such as the display magnification and display time of the face area, the face area is reproduced and displayed according to the set reproduction display contents. However, it is not always necessary to reproduce and display after setting the reproduction display contents of the face area.
That is, for example, the image data relating to the detected face area and the data indicating the reproduction display contents of the face area are stored in a predetermined storage means such as a recording medium detachably attached to the main body of the image display apparatus 100, for example. Thus, by using the stored data, for example, the face area is reproduced and displayed at a later date, or the face is displayed using a display device (not shown) different from the image display device 100. It is possible to reproduce and display the area.

Furthermore, in the image reproduction process in the above embodiment, when the operation point instructed to input before the lapse of the predetermined period in step S3 or S10 is separated from the operation point instructed last time by a predetermined interval or more, the user It may be determined that the first drawing operation of the touch panel 2a is completed and the second drawing operation is started. In such a case, based on each of the first drawing operation and the second drawing operation, the image data relating to the detected face area and the data indicating the reproduction display contents of the face area are first and second times. By separately managing files, the playback display timings of the face area detected based on the first drawing operation and the face area detected based on the second drawing operation may be made different. .
On the other hand, in contrast to the above, in step S3 or S10, even when the operation point instructed to input before the predetermined period elapses is more than a predetermined interval from the operation point instructed last time, the touch panel by the user You may make it judge that it is a series of 2a drawing operation. For example, when the face area displayed on the edge of the image display area of the display panel 1a is designated, there is a possibility that the user's finger or touch pen may jump out from the outer edge of the touch panel 2a. The position where the user's finger or touch pen protrudes from the outer edge of the touch panel 2a and the position where the user's finger or touch pen returns to the detection range of the touch panel 2a are greatly shifted. Even in such a case, by determining that the drawing operation of the touch panel 2a by the user is a series, all the face areas detected based on the drawing operation can be reproduced as a slide show.

  Furthermore, the configuration of the image display apparatus 100 is merely an example illustrated in the above embodiment, and is not limited thereto. Further, the image display device 100 installed at a predetermined position is exemplified as the image reproduction device, but the image display device 100 is not limited to this. For example, the predetermined image processing according to the present invention such as an imaging device including the display unit 1 is performed. Any configuration may be used as long as it can execute the above.

In addition, in the above embodiment, the functions as the specifying unit, the detecting unit, and the setting unit are controlled under the control of the central control unit 7, the operation locus specifying unit 3, and the specific region detecting unit 4 a of the image processing unit 4. The playback display content setting unit 4b is driven to drive the configuration. However, the configuration is not limited to this, and the configuration realized by the CPU of the central control unit 7 executing a predetermined program or the like. Also good.
That is, a program including a specific processing routine, a detection processing routine, and a setting processing routine is stored in a program memory (not shown) that stores the program. Then, the CPU of the central control unit 7 specifies an operation locus L formed by connecting a plurality of operation points instructed based on a predetermined operation of the operation input means by the user in the image display area of the display means by the specifying processing routine. You may make it function as a specific means to do. In addition, the CPU of the central control unit 7 may function as a detection unit that detects a specific area overlapping the operation locus L specified by the specification unit from the image displayed on the display unit by a detection processing routine. In addition, the CPU v of the central control unit 7 in the setting process routine sequentially instructs to input a plurality of operation points constituting the operation locus L that overlaps the specific area detected by the detection unit based on a predetermined operation of the operation input unit. May be made to function as a setting means for setting the display magnification of the specific area based on the operation instruction speed v.

  Furthermore, as a computer-readable medium storing a program for executing each of the above processes, a non-volatile memory such as a flash memory and a portable image recording unit such as a CD-ROM are applied in addition to a ROM and a hard disk. It is also possible. A carrier wave is also used as a medium for providing program data via a predetermined communication line.
