Description

  The present invention relates to a recording / reproducing apparatus and a recording / reproducing method, and is particularly suitable for application to an optical disc recording / reproducing apparatus having a so-called slide show display function.

  2. Description of the Related Art Conventionally, a video playback device such as an electronic imaging device such as a digital camera or a DVD (Digital Versatile Disk) recorder has a function of displaying a plurality of images designated by the user one by one as one of the playback functions ( This is hereinafter referred to as a slide show display function).

In such a slide show display function, normally, a plurality of images recorded on a recording medium are displayed as a list of thumbnail images on the display screen, and desired thumbnail images designated by the user are sequentially displayed one by one for the same set time. An enlarged display is made (see, for example, Patent Document 1).
JP 2003-288068 A ([0067] and [0073], FIGS. 7 and 8)

  By the way, most of conventional imaging devices and video playback devices equipped with such a slide show display function do not store setting information such as the display time of each image set at the time of slide show display. The current situation is that the setting information is lost when the power supply of the entire apparatus is turned off.

  On the other hand, even when a device capable of storing setting information is used, it is generally stored in a non-volatile memory or the like built in the device, and a device that stores data in a removable recording medium has been proposed. Therefore, it is very difficult to make the setting contents effective in other apparatuses other than the apparatus. If the slide show display function is executed in another device, resetting by the user is necessary, and the operation for that is complicated.

  In setting the display time in the slide show display function, first, if the same display time is set for all the images as in the cited document 1, the desired total time required for the slide show display. There is a problem in that it is necessary to execute an arithmetic process for dividing the entire time by the number of all the designated images.

  Secondly, in the case of setting so that only the image desired by the user is displayed with different time lengths, most of the time sets the display time individually for each image. There is a complexity that must be performed by the number of designated images, and there is a possibility that the calculation processing for setting the total time required for the slide show display to a desired time becomes very complicated.

  Therefore, if the total time required for the slide show display can be freely set to a time desired by the user regardless of the number of images, it is possible to obtain the convenience that all images can be visually confirmed within the time specified by the user. it can. In addition, it is highly desirable that the setting contents of the slide show display can be reflected not only in this apparatus but also in other apparatuses via a recording medium.

  The present invention has been made in consideration of the above points, and an object of the present invention is to propose a recording / reproducing apparatus and a recording / reproducing method capable of easily reflecting the setting contents according to the user's preference in other models.

  In order to solve this problem, the present invention relates to a reading means for reading a plurality of images recorded on a recording medium and a display function for sequentially reproducing a plurality of designated images one by one from the plurality of images. Setting input means for inputting setting contents related to the function, control means for controlling the reproduction time of each image at the time of executing the display function based on the total time required for reproducing the designated image among the setting contents; Recording means for recording the setting contents on a recording medium is provided.

  As a result, in this recording / reproducing apparatus, when executing a display function for sequentially reproducing each specified image among a plurality of images recorded on the recording medium, the reproduction time of each image is simply set at equal intervals. In addition to setting the above, the setting content is recorded on the recording medium after the setting is made regardless of the number of images to be reproduced on the basis of the total time required for reproduction of the designated image. In addition to being able to execute the display function in a display mode according to the user's preference, the setting contents can be easily reflected in other recording / reproducing means via the recording medium.

  In the present invention, the first step for reading a plurality of images recorded on a recording medium and the display function for sequentially reproducing a plurality of designated images one by one from the plurality of images are set for the display function. When the contents are input, a second step for controlling the reproduction time of each image when the display function is executed and the setting contents are recorded based on the total time required for reproducing the designated image among the setting contents. And a third step of recording on the medium.

  As a result, in this recording / reproducing method, when executing a display function for sequentially reproducing each specified image among a plurality of images recorded on the recording medium, the reproduction time of each image is simply set at equal intervals. In addition to setting the above, the setting content is recorded on the recording medium after the setting is made regardless of the number of images to be reproduced on the basis of the total time required for reproduction of the designated image. In addition to being able to execute the display function in a display mode according to the user's preference, the setting contents can be easily reflected in other recording / playback techniques via the recording medium.

  As described above, according to the present invention, the display function includes a reading unit that reads a plurality of images recorded on a recording medium, and a display function that sequentially reproduces a plurality of designated images one by one. Setting input means for inputting setting contents related to the control means, control means for controlling the reproduction time of each image when the display function is executed, based on the total time required for playing the designated image of the setting contents, and setting By providing a recording means for recording the contents on the recording medium, the reproduction time of each image can be set regardless of the number of images to be reproduced on the basis of the total time required for reproduction of the designated image. Thus, it is possible to realize a recording / reproducing apparatus that can easily reflect the setting contents according to the user's preference in other models.

  In the present invention, the first step for reading a plurality of images recorded on a recording medium and the display function for sequentially reproducing a plurality of designated images one by one from the plurality of images are set for the display function. When the contents are input, a second step for controlling the reproduction time of each image when the display function is executed and the setting contents are recorded based on the total time required for reproducing the designated image among the setting contents. By providing the third step for recording on the medium, it is possible to set the playback time of each image regardless of the number of images to be played back, based on the total time required to play back the designated image. Thus, it is possible to realize a recording / reproducing method that can easily reflect the setting contents according to the user's preference in other models.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

(1) Configuration of optical disc recording / reproducing apparatus according to the present embodiment In FIG. 1, reference numeral 1 denotes an optical disc recording / reproducing apparatus according to the present embodiment as a whole. ) The video signal S3 and the audio signal S4 recorded in 2 or reproduced from the optical disc 2 can be output to the outside.

  That is, in the optical disc recording / reproducing apparatus 1, when a recording mode is selected according to the operation of the operation unit 3 by the user, the system control microcomputer 4 that controls the entire apparatus is sequentially supplied from an external device (not shown). The video signal S1 and the audio signal S2 are input to the video encoder 6 and the audio encoder 7 through the input terminals 5A and 5B, respectively, are subjected to predetermined encoding processing, and are supplied to the file generator 8.

  The file generator 8 generates file data D3 synthesized by synchronizing the encoded video data D1 and audio data D2 under the control of the system control microcomputer 4, and then sends them to the memory controller 9. The memory controller 9 sends the file data D3 to the error correction encoder / decoder 11 while using the memory 10 as a buffer as necessary. For example, the memory controller 9 performs predetermined error correction every sector (2 [kbyte]). After adding the code, it is sent to the subsequent data modulator / demodulator 12 to perform EFM (Eight to Fourteen Modulation) modulation processing, and the recording data D4 thus obtained is sent to the optical pickup 13 and the magnetic field modulation driver 14.

  The optical pickup 13 has optical system devices such as a laser diode, a collimator lens, an objective lens and a light receiving element, and an electrical system device such as a laser diode driver, and a light beam modulated in accordance with supplied recording data D4. The recording surface of the optical disc 2 is irradiated.

  At this time, the optical pickup 13 generates a servo error signal S5 such as a tracking error signal and a focus error signal based on the reflected light from the optical disc 2, and a push-pull signal S6. Then, the data is sent to the drive control microcomputer 15 via the error correction code / decoder 11.

  The drive control microcomputer 15 drives the spindle motor 17 by controlling the servo circuit 16 based on the supplied servo error signal S5, thereby rotating the optical disc 2 at a predetermined speed. Further, the drive control microcomputer 15 controls the magnetic field modulation driver 14 via the error correction code / decoder 11 and the data modulator / demodulator 12 based on the servo error signal S5 to drive the sled motor 18, thereby A beam spot of a light beam (hereinafter simply referred to as a beam spot) is moved in the radial direction of the optical disc 2 along a data track (pre-groove or land) formed on the recording surface of the optical disc 2.

  Further, the drive control microcomputer 15 controls the servo circuit 16 based on the servo error signal S5 to drive and control a biaxial actuator (not shown) in the optical pickup 13, thereby performing tracking control and focus control.

  On the other hand, the data modulator / demodulator 12 detects the absolute address of the beam spot at that time on the optical disc 2 by decoding the supplied push-pull signal S6, and this is detected by the error correction code / decoder 11 and the subsequent memory controller. 9 is sent to the system control microcomputer 4 via 9.

  That is, the data modulator / demodulator 12 is included in the push-pull signal S6 by passing the push-pull signal S6 through a band-pass filter circuit in the range of ± 1 [kHz] having a center frequency of 22.05 [Hz] provided therein. The wobble component is extracted and FM demodulation processing is performed on the wobble component to detect the absolute address on the optical disc 2 where the beam spot is located at this time, and this is sent to the system control microcomputer 4 as address information S7. .

  Each time the data modulator / demodulator 12 changes the absolute address on the optical disc 2 obtained by the decoding process as described above (that is, every time the sector in which the beam spot on the optical disc 2 scans) changes, The embedded signal S8 is sent to the system control microcomputer 4 via the error correction code / decoder 11 and the subsequent memory controller 9.

  Thus, the system control microcomputer 4 sequentially recognizes the current recording position on the optical disc 2 based on the address information signal S7 and the sync interrupt signal S8 given from the data modulator / demodulator 12, and records data based on the recognition result. Necessary control processing is executed so that D4 can be correctly recorded on the optical disc 2.

  On the other hand, when the playback mode is selected according to the operation of the operation unit 3 by the user, the system control microcomputer 4 controls the drive control microcomputer 15 to perform the same operation as in the above-described recording mode. Is rotated at a predetermined speed, the beam spot is moved along the data track of the optical disc 2, and tracking control and focus control are performed.

  Further, the system control microcomputer 4 drives the laser diode in the optical pickup 13 described above to emit a light beam toward the optical disc 2. As a result, this light beam is reflected on the recording surface of the optical disk 2 and read data D5 read from the optical disk 2 as an RF signal obtained based on the reflected light is error-corrected from the optical pickup 13 via the data modulator / demodulator 12. It is provided to the encoder / decoder 11.

  The error correction code / decoder 11 includes a PLL (Phase Locked Loop) circuit, a synchronization data detection unit, an EFM demodulation unit, a CIRC decoding unit, and a layered ECC demodulation unit. From the read data D5 supplied in the PLL circuit. The clock is extracted, and the extracted clock is sent to the synchronous data detection unit together with the read data D5.

  The synchronization data detection unit generates a synchronization data detection window pulse having a pulse width larger by a predetermined pit before and after the above-described synchronization data data pattern based on the supplied clock. The synchronous data detection unit sequentially detects the synchronous data detection window pulses and sequentially sends the read data D5 to the EFM demodulation unit in predetermined units based on the detection result.

  The read data D5 is then EFM demodulated in the EFM demodulator, CIRC decoded in the CIRC decoder, and further subjected to error correction in the layered ECC demodulator, so that the original format before recording is obtained. The data is converted into data, and then sent to the file decoder 19 via the memory controller 9. The error correction code / decoder 11 is configured to use the memory 20 as a buffer as necessary when executing the various processes described above.

  The file decoder 19 separates the read data D5 into video data D6 and audio data D7, and then sends them to the video decoder 21 and the audio decoder 22, respectively. The video decoder 21 performs a predetermined decoding process on the video data D6, and then outputs the video data D6 to the outside via the output terminal 23A and sends it to the display unit 24 to display the video on the display screen. The audio decoder 22 performs a predetermined decoding process on the audio data D7, and then outputs the audio data D7 to the outside via the output terminal 23B and sends it to the speaker 25 for audio output.

  In this way, the optical disc recording / reproducing apparatus 1 records the externally supplied video signal S1 and audio signal S2 on the optical disc 2, and reproduces the video / audio data (read data) D5 recorded on the optical disc 2. And can be output to the outside.

  The display unit 24 has a configuration in which a touch panel (not shown) is superimposed on a display screen made up of an LCD (Liquid Crystal Display). Such a touch panel is configured to recognize the contact position as a coordinate position using the display screen as a two-dimensional coordinate system when contact is made from outside.

  Further, the setting input unit F1C is provided with setting buttons BT3 to BT5 for “delete”, “play”, and “create slide show” between the arrow buttons BT1 and BT2 at both left and right ends. Among these, the “delete” setting button BT3 is a button for deleting a file corresponding to the thumbnail image designated by the user among the thumbnail images SN1 to SN8 of the plurality of files displayed on the content display portion F1A. The “play” setting button BT4 is a button for playing a file corresponding to the thumbnail image designated by the user among the thumbnail images SN1 to SN8 of the plurality of files displayed on the content display portion F1A. Furthermore, the “Create slide show” setting button BT5 is a button for transition to a slide show setting screen F2 shown in FIG.

  In this way, on the content selection screen F1, various contents (moving images, still images, or slide show images) recorded on the optical disc 2 are displayed as a list on the display screen of the display unit 24 for each file. The content corresponding to the file designated by the user can be changed to a reproduction operation for display.

(2-2) Display of Slide Show Setting Screen Subsequently, in the optical disc recording / reproducing apparatus 1, the optical disc 2 is loaded, and the content selection screen F1 shown in FIG. 2 described above is displayed on the display screen of the display unit 24 according to the user's operation. When the “Create Slide Show” setting button BT5 in the setting input unit F1C of the content selection screen F1 is designated (tapped), the display screen of the display unit 24 has a display as shown in FIG. A slide show setting screen F2 is displayed.

  The slide show setting screen F2 includes a target image display unit F2A in which a plurality of images forming a slide show image group read from the optical disc 2 are displayed in a list with a predetermined arrangement pattern, and various display parameters such as the total playback time and the number of slide shows. The numerical value display portion F2B for displaying the numerical content of the above and the setting input portion F2C for inputting various setting content.

  Among these, the target image display unit F2A displays a list of thumbnail images SN10 to SN17 each obtained by reducing a plurality of images to a predetermined size in a predetermined arrangement pattern (for example, vertical and horizontal 2 × 4) by a predetermined number (for example, 8). In the lower part of the thumbnail images SN10 to SN17, title character string display fields M10 to M17 such as names and serial numbers, and a playback time of the image at the time of the slide show display (hereinafter referred to as image playback). Display columns ST0 to ST7 of “time”.

  Up and down buttons UD0 to UD7 are displayed on the right end side of the image reproduction time display columns ST0 to ST7, and a GUI (Graphic User Interface) is displayed. The image reproduction time is expressed in seconds in accordance with a user operation (mainly a tap). It can be incremented or decremented.

  The numerical value display portion F2B also displays a “total playback time” display field M20 indicating the total time required for slide show display (hereinafter referred to as the total playback time) in units of minutes and the current image of the image selected as the slide show display. "Slide show number" display field M21 indicating the selected number of images and the current page number relative to the total number of pages when all the images forming the designated slide show image group are set to one page in units of eight. It comprises a “page” display field M22.

  Further, the setting input unit F2C is provided with arrow buttons BT10 and BT11 represented by “←” and “→” at both left and right ends, and the number of pages is incremented each time the right end arrow button BT11 is designated (tapped). Each time the leftmost arrow button BT10 is designated (tapped), the number of pages is decremented, and at the same time, the current number of pages in the “page” display field is increased or decreased accordingly.

  The setting input unit F2C includes setting buttons BT12 to BT16 of “select all”, “setting”, “slide show start”, “slide show setting save”, and “return” between the arrow buttons BT10 and BT11 at both left and right ends. Is provided. Among these, the “select all” setting button BT12 is a button for selecting all images for slide show display. When actually designated (tapped), all images are selected and the target image is selected. The outer frames of all thumbnail images SN10 to SN17 in the display unit F2A are displayed in bold.

  The “setting” setting button BT13 is a button for transitioning to a setting option screen F3 shown in FIG. 4 to be described later, and can set conditions included in the slide show and various reproduction times. Further, the “slide show start” setting button BT14 is a button for starting the slide show with the current setting contents, and the “slide show setting saving” setting button BT15 converts the current setting contents into a slide show file to be described later. This is a button for recording on the optical disc 2. The “return” setting button BT16 is a button for transitioning to the content selection screen F1 shown in FIG. 2 described above.

  Here, the setting option screen F3 shown in FIG. 4 is a GUI screen for setting conditions to be included in the slide show, and the date and time when all the images forming the slide show image group were previously displayed on the screen other than the slide show playback. Based on the above, a reproduction period designation input unit F3A for specifying an object that falls within the range designated as the target period, and a reproduction time setting input unit F3B for setting the image reproduction time of each image during slide show display It consists of and.

  This reproduction period designation input unit F3A sets the start time and the end time of the screen reproduction period in order to designate a period during which an image is displayed on the screen other than the past slide show (hereinafter referred to as a screen reproduction period). By inputting, it is possible to specify only images displayed on the screen other than slide show reproduction within the screen reproduction period.

  Specifically, the reproduction period designation input unit F3A inputs the start time when the up / down buttons UD10 to UD15 are displayed on the GUI for each year / month / day only when the check point CP1 indicating “reproduction period designation” at the left end is in an ON state. The part F3AX and the end time input part F3AY are both effective, and the up and down buttons UD10 to UD15 in the start time input part F3AX and the end time input part F3AY are operated (tapped), respectively, so that the user desires The day is made so that it can be determined.

  The reproduction time setting input unit F3B has setting item fields M30 and M31 for “equal interval reproduction” and “whole time designation”, and the lower part of each setting item field M30 and M31 is respectively up and down every minute and second. A time input field M32 in which buttons UD16 and UD17 are displayed on the GUI is provided. The time input field M32 is valid when any of the setting items of “equal interval reproduction” or “whole time designation” is selected, and time input according to the selected setting item is possible.

  First, when the “Equal Interval Playback” setting item is selected, the image playback time for each image displayed one after another as a slide show can be set to the same time interval. Each time the up / down buttons UD16, UD17 are operated (tapped), the image reproduction time can be determined at the same time interval desired by the user.

  On the other hand, when the “total time designation” setting item is selected, the total playback time required for the slide show display can be set. At this time, in the time input field M32, the up and down buttons UD16 and UD17 for every minute and second are operated ( Each time it is tapped), the user can determine the desired total playback time.

  Furthermore, only when the setting item of “Specify total time” is selected, “Equal playback”, “Focus on the number of playbacks so far” and “Focus on the playback time so far” In the setting item fields M33 to M35, the setting items designated by the user are set to be valid.

  When the “Equal Interval Playback” setting item is selected, the image playback time of each image is automatically obtained so that each image is played back at equal intervals within the entire playback time required for the slide show display. Has been made. Specifically, when the total playback time required for the slide show display is t_Time and the number of images forming the slide show image group is t_Num, the image playback time e_Time of each image is given by

It is required as follows.

  In addition, when the setting item “emphasis on the number of reproductions so far” is selected, the image reproduction time is preferentially allocated from the image having the largest total number of reproductions. Here, the number of reproductions is, for example, the number of reproduction operations performed by the user other than the slide show reproduction for a certain image. As a result, the longer the playback time is allocated in the slide show, the more images the user has viewed.

  Further, when the setting item of “emphasis on playback time so far” is selected, still image playback time is preferentially assigned from the longest cumulative playback time of each still image. Here, the reproduction time is the total of the time during which an image is displayed on the display unit based on a reproduction operation instruction given by the user in addition to the slide show reproduction. As a result, an image that the user has been browsing for a longer time is assigned a longer playback time in the slide show playback.

  In the lower right part of the setting option screen F3, as the setting input unit F3C, a setting button BT20 for “setting execution” for executing the current setting contents and a setting of “cancel” for canceling the current setting contents are set. A button BT21 is provided.

(3) Slide show setting processing procedure In the optical disc recording / reproducing apparatus 1, when the reproduction operation of the optical disc 2 loaded in response to a user operation is actually started, the system control microcomputer 4 performs the slide show shown in FIGS. The setting processing procedure RT1 is started from step SP0, and in the subsequent step SP1, the above-described content selection screen F1 shown in FIG. 2 is displayed on the display screen of the display unit 24.

  Subsequently, in step SP2, the system control microcomputer 4 determines whether or not a desired slide show image group has been designated using the content selection screen F1, waits for an affirmative result, and then proceeds to step SP3. The slide show setting screen F2 as shown in FIG. 3 is displayed on the display screen of the display unit 24.

  Further, the system control microcomputer 4 proceeds to step SP4, determines whether or not the reproduction period is designated by using the setting option screen F3 shown in FIG. 4 derived from the slide show setting screen F2, and a positive result is obtained. In this case, the process proceeds to step SP5, where only thumbnail images representing images within the designated reproduction period are displayed as a list on the target image display unit F2A of the slide show setting screen F2, and then the process proceeds to step SP6 while a negative result is obtained. If yes, the process proceeds to step SP6.

  In this step SP6, the system control microcomputer 4 makes a table (hereinafter, referred to as a correspondence relationship) between the slide show image groups corresponding to all the thumbnail images SN10 to SN17 displayed in a list on the slide show setting screen F2 and these file names. This is called a slide show target image table) and stored in the memory 10.

  Eventually, the system control microcomputer 4 proceeds to step SP7, determines whether or not the setting item of the total playback time is selected using the setting option screen F3, and whether or not the total time required for the slide show display is input, and the positive result is If it is obtained, the process proceeds to step SP8, and after acquiring the input total reproduction time, the process proceeds to step SP9.

  In step SP9, the system control microcomputer 4 determines whether or not weighting based on the reproduction frequency is specified. If a positive result is obtained, the process proceeds to step SP10, where the reproduction frequency data interpretation processing procedure as a subroutine is performed. After executing RT2 (FIG. 9 described later), the process proceeds to step SP11. On the other hand, if a negative result is obtained in step SP9, the system control microcomputer 4 proceeds to step SP12 and acquires an equal interval time obtained by dividing the total reproduction time by the number of all images. Thereafter, the process proceeds to step SP11.

  On the other hand, if a negative result is obtained in step SP7, this means that the total reproduction time has not been designated, and at this time, the system control microcomputer 4 proceeds to step SP13 to set the setting option screen. It is determined whether or not a setting item for the equal interval time is selected using F3 and a common time interval is input. If an affirmative result is obtained, the process proceeds to step SP14, and the input equal interval is determined. After obtaining the time, the process proceeds to step SP11. On the other hand, if a negative result is obtained in step SP13, the system control microcomputer 4 proceeds to step SP15, acquires the reproduction time of each designated image, and then proceeds to step SP11.

  In step SP11, the system control microcomputer 4 determines whether there is an increase / decrease change in the images forming the slide show image group, and proceeds to step SP16 only when a negative result is obtained, while an affirmative result is obtained. In this case, the process returns to step SP2 and the same process as described above is repeated.

  In step SP16, the system control microcomputer 4 determines the image playback time for each image forming the slide show image group based on the acquired various playback times, and then proceeds to step SP17 to create a slide show setting table. To do.

  Further, in step SP18, the system control microcomputer 4 converts the slide show setting table into a slide show file having a predetermined data format and records it on the optical disc. Then, the system control microcomputer 4 proceeds to step SP19 and ends the slide show setting processing procedure RT1.

  As described above, in the optical disc recording / reproducing apparatus 1, the desired still image display time of each image forming the slide show image group using the slide show setting screen F2 is required for the slide show display according to the user's selection as well as the equal interval time. The entire playback time can be set as a reference, and the set content can be recorded on the optical disc as a slide show file.

  As shown in FIG. 7, the slide show file SF1 is file data representing a slide show setting table set for one slide show image group. The slide show file name assigned to the slide show image group and the slide show image are displayed. The number of slide shows (= n) indicating the number of images forming a group, and slide show reproduction information No. indicating management information for each image. 1-No. n is described in order.

  Among these, slide show reproduction information No. 1-No. n is continuously arranged in the order of reproduction by the total number of all images, the still image file name attached to the corresponding image, the image reproduction time indicating the reproduction time of the image at the time of the slide show, and an arbitrary recording It describes metadata that represents possible data.

  When the slide show file SF1 is actually recorded on the optical disc 2, any file such as “SLIDE001.PLF” can be arbitrarily selected as a file representing other images without specifying a special recording area. Recorded in the recording area. Also, the slide show reproduction information No. that forms the slide show file SF1. 1-No. Files “001.JPG”, “012.JPG”, “120.JPG”,... representing each image corresponding to n are also recorded in an arbitrary recording area of the optical disc 2.

  In FIG. 7, since the file “SLIDE001.PLF” represents the slideshow file SF1 itself, the correspondence from the slideshow file SF1 to the file is indicated by a white arrow, but the files “001.JPG”, “012.JPG”, “120.JPG”,... Is a slideshow reproduction information No. 1-No. Since the image file corresponding only to each of n is merely indicated, the slide show reproduction information No. 1-No. The correspondence is displayed with a simple arrow from n to the corresponding file.

(4) Reproduction Frequency Data Interpretation Processing Procedure Here, the optical disk 2 has a file name for each content as management information for managing various types of recorded content (moving images, still images, and slide show images). And a metadata, which is various information regarding the corresponding content, are formed, and a collection of these title entries is recorded as a single title file TF1.

  As shown in FIG. 8A, the title file TF1 includes a title entry No. corresponding to the top title header and various contents (moving image, still image, or slide show image group). 1-No. k (k is a natural number) is described.

  Of these, for example, the title entry No. When 2 is a title entry corresponding to a slide show file, the corresponding slide show file name and metadata MD2 relating to the slide show file are recorded in the title entry (FIGS. 8A and 8C). .

  Here, in the metadata MD1 of the title entry for the image file (for example, title entry No. 1 in FIG. 8A), a reproduction frequency data entry recorded every time the corresponding image is reproduced by other than the slide show function. 1 to m are recorded in the order of reproduction (hereinafter referred to as reproduction frequency data).

  The slide show reproduction information No. that forms this slide show file SF1. 1-No. In the metadata MD1 described in n, reproduction frequency data entries 1 to n corresponding to the number of reproductions other than the past slide show are described in the reproduction order (hereinafter referred to as reproduction frequency data).

  Each of the reproduction frequency data entries 1 to n forming the reproduction frequency data MD1 includes reproduction date / time information indicating the date / time (year / month / day) when the image is displayed on the screen other than the slide show reproduction, and the time (hours) displayed on the screen. Reproduction time information representing minutes and seconds) is described (FIGS. 8E and 8F).

  Actually, in step SP10 of the slide show setting processing procedure RT1 described above with reference to FIG. 5, the system control microcomputer 4 starts the reproduction frequency data interpretation processing procedure RT2 shown in FIG. 9 as a subroutine, and in the subsequent step SP20, reproduction is performed as the reproduction frequency. It is determined whether the number of times or the playback time is selected.

  Specifically, in the state where the “whole time playback” setting item is selected in the playback time setting input section F3B of the setting option screen F3 shown in FIG. It is determined whether or not any of the setting items of “emphasis on playback time until” is selected.

  When the number of reproductions is selected in step SP20, the system control microcomputer 4 proceeds to step SP21 and accumulates the number of reproduction operations performed by the user other than the past slide show reproduction (hereinafter referred to as cumulative reproduction). (Referred to as “number of times”) is used to interpret the reproduction date information and reproduction time information included in all reproduction frequency data entries 1 to m (FIGS. 8E and 8F) of the reproduction frequency data MD1 corresponding to the corresponding image. After the calculation, the process proceeds to step SP22.

  On the other hand, when the playback time is selected in step SP20, the system control microcomputer 4 proceeds to step SP23 and corresponds to the cumulative playback time obtained by the sum of the times during which the image was displayed on the screen other than the slide show playback in the past. After calculating so as to interpret the reproduction date and time information and the reproduction time information included in all the reproduction frequency data entries 1 to m of the reproduction frequency data MD1 corresponding to the image, the process proceeds to step SP22.

  In this step SP22, the system control microcomputer 4 is a table (hereinafter referred to as a reproduction frequency holding table) representing the correspondence between each image forming the slide show image group and their reproduction frequency (cumulative reproduction number or cumulative reproduction time). Is created or updated and stored in the memory 10, and then the process proceeds directly to step SP11 of the slide show setting process procedure RT1 shown in FIG. 6 and the reproduction frequency data interpretation process procedure RT2 is terminated.

  As a result, the system control microcomputer 4 weights the reproduction frequency (accumulated reproduction number or accumulated reproduction time) based on the reproduction frequency holding table read from the memory 10 in step SP16 of the slide show setting processing procedure RT1 shown in FIG. Then, the image reproduction time for each image forming the slide show image group is determined.

  Specifically, the sum of the playback frequencies (cumulative playback count or cumulative playback time) of all images forming the slide show image group is set to Σf, and the total playback time required for the slide show display is set to t_Time to form the slide show image group. Assuming that the reproduction frequency of each image is f_e, the image reproduction time e_Time of each image is given by

It is required as follows.

The displayed image is displayed on the display screen of the display unit 24.

  Subsequently, the system control microcomputer 4 proceeds to step SP32, acquires the date and time (year / month / day) by measuring the display start time of the designated image, creates reproduction date / time information, and then proceeds to step SP33. Thus, it is determined whether or not the reproduction of the image has been terminated by the user's operation, and the process waits until an affirmative result is obtained.

  Next, the system control microcomputer 4 obtains an affirmative result in step SP33 and simultaneously measures the display end time of the image. Then, the system control microcomputer 4 proceeds to step SP34 and displays the time (hour / minute / second) when the designated image is displayed on the screen. Calculate and create playback time information.

  Thereafter, in step SP35, the system control microcomputer 4 generates a reproduction frequency data entry using the reproduction date / time information and the reproduction time information, and proceeds to the subsequent step SP36, where the reproduction frequency data entry corresponding to the image is reproduced. After updating to be added to the data MD1, the process proceeds to step SP37 and the reproduction frequency data update processing procedure RT3 is terminated.

  Subsequently, in step SP42, the system control microcomputer 4 obtains the total number of images forming the slide show image group based on the description content in the slide show file SF1, and then proceeds to step SP43 to display the slide show corresponding to the images. Playback information No. The still image file name described in i (i is an arbitrary natural number) is acquired.

  Then, the system control microcomputer 4 proceeds to step SP44, where the slide show reproduction information No. After acquiring the image playback time described in i, the process proceeds to step SP45, where an image corresponding to the acquired still image file name is read from the optical disc 2 and displayed on the display image of the display unit 24.

  Next, the system control microcomputer 4 proceeds to step SP46 and waits for the image reproduction time to elapse in subsequent step SP47 while starting measurement of the image reproduction time.

  If an affirmative result is obtained in step SP47, that is, if the image reproduction time has elapsed, the system control microcomputer 4 proceeds to step SP48, where the slide show reproduction information No. It is determined whether i is the last reproduction order (No. n), and if a negative result is obtained, the process proceeds to step SP49 and the next slide show reproduction information No. i is obtained. i is read from the slide show file, then the process returns to step SP43 again, and the slide show reproduction information No. The above-described steps SP44 to SP49 are repeated for i.

  If an affirmative result is eventually obtained in step SP48, this means that all slide show reproduction information Nos. This shows that the image corresponding to n is displayed on the display screen of the display unit 24. At this time, the system control microcomputer 4 proceeds to step SP50 and ends the slide show reproduction processing procedure RT4.
