BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus, an imaging apparatus, and a content selection method capable of reproducing and outputting a plurality of types of content recorded on a recording medium, and in particular, information in which a content selection operation is performed using a small touch panel. The present invention relates to a processing device, an imaging device, and a content selection method.

[Prior art]
In recent years, home digital still cameras and digital video cameras capable of capturing still images and moving images and recording them as digital data have become widespread. Recently, as the capacity of recording media has increased, it has become possible to record a large number of image files on a recording medium, so that the recorded image files can be efficiently searched for and displayed or printed. In addition, there is an increasing demand for output to an external printer.
[0003]
For example, many of the above-described digital imaging apparatuses can reproduce and display recorded images on a liquid crystal display for adjusting the angle of view during shooting. However, simply replaying and displaying the recorded images one after another on the liquid crystal display in the order in which the images were taken is inefficient in finding a large number of images. On the other hand, it is considered that a reduced image of a recorded image (a reduced image of a representative scene in the case of a moving image, for example) is displayed as a list on a liquid crystal display and is reproduced and displayed by selection. In addition, there has been an image pickup apparatus that uses a touch panel type liquid crystal display to select and reproduce an image by pressing the display.
[0004]
Furthermore, it has been considered that a reduced image is displayed on a calendar displayed on a liquid crystal display so that an image taken at a specific date and time can be easily found. As such, display the monthly calendar display screen on the display unit, search the date column of the date editing table with the current year and month, and extract and play back the reduced images of images taken within that month. In addition, there has been a captured image display device that displays a date on a calendar display screen by date and reproduces and displays a captured image by pointing to a desired image from the displayed reduced images (for example, see Patent Document 1).

[Problems to be solved by the invention]
By the way, since the imaging apparatus as described above is always required to be downsized, a large-screen liquid crystal display cannot be mounted. For this reason, when a file selection or playback operation is performed using a touch-panel type liquid crystal display, the display area of the selection item is reduced, and thus erroneous operations such as a push error are often performed. There is a demand for icon arrangement and screen transition that prevent such erroneous operations as much as possible.
[0007]
Recently, many digital still cameras are capable of recording / reproducing not only still images but also moving images and recording / reproducing audio. In such a digital still camera, there is a demand for further improvement in efficiency and operational feeling for finding and playing back recorded image and audio files. Similarly, many digital video cameras are capable of recording / reproducing moving images, still images, and audio, and in the future, such as writable optical disks and hard disks as recording media for digital video cameras. Since it is considered to be used, it is considered that the demand for efficiently searching for and reproducing the recording file by utilizing the random accessibility in these recording media will increase.
[0008]
The present invention has been made in view of such problems, and an information processing apparatus that easily searches for, reproduces, and outputs various types of content recorded on a recording medium, and prevents erroneous operations at that time. The purpose is to provide.
[0009]
Another object of the present invention is to provide an imaging apparatus in which various types of content recorded on a recording medium can be easily searched, reproduced and output, and erroneous operation at that time is prevented.
[0010]
Furthermore, another object of the present invention is to provide a content selection method for easily searching, reproducing and outputting various types of content recorded on a recording medium, and preventing erroneous operation at that time. .
[0011]

In the present invention, in order to solve the above problems, in an information processing apparatus capable of reproducing and outputting a plurality of types of content recorded on a recording medium, display means for displaying an image, and display on the display surface of the display means A selection unit that detects contact and receives a selection operation by a user; and a display control unit that changes a display screen of the display unit according to the selection operation. The display control unit is created during a predetermined period. The selection operation is performed at least twice from a state in which a monthly list display screen in which an identification image indicating that the content exists in the recording medium is arranged on a calendar for one month is displayed. There is provided an information processing apparatus characterized in that a transition is made to a date-by-date list display screen in which the identification images indicating the existence of the content created on a specific day are displayed as a list.
[0012]
Here, the display means displays an image, and the selection means detects contact with the display surface of the display means and receives a selection operation by the user. The display control means changes the display screen of the display means according to the selection operation using the selection means. Under the control of the display control means, a state in which a monthly list display screen in which an identification image indicating that content created during a predetermined period exists in the recording medium is arranged on the calendar for one month is displayed on the display means Then, when at least two selection operations are performed in the selection unit, the screen transits to a date-based list display screen displaying a list of identification images indicating the existence of content created on a specific day. By such control, the contents in the recording medium are arranged and displayed for each period, and the selection operation can be performed. For example, the user can check whether the identification image selected on the monthly list display screen is intended. After confirming this, or by increasing the display area of the identification image to increase the certainty of the selection operation, it is possible to transition to the date-by-date list display screen, and select and reproduce and output the content.

[0014]
In such a content selection method, after displaying a monthly list display screen in which an identification image indicating that content created during a predetermined period exists in a recording medium is arranged on a calendar for one month, this monthly list is displayed. When the selection operation is performed at least twice from the display screen using the touch panel, the screen display is changed to a list display screen by date displaying a list of identification images indicating the existence of content created on a specific day. Be controlled. As a result, the contents in the recording medium are arranged and displayed for each period, and a selection operation is possible. For example, the user confirms whether the identification image selected on the monthly list display screen is intended or not. In addition, after increasing the display area of the identification image to increase the certainty of the selection operation, it is possible to transition to the date-by-date list display screen, select the content, and reproduce and output it.

The timing generation circuit 16 generates a timing signal based on the control signal from the control unit 50 and controls the drive timing of the CCD 12 and the driver 15.
[0021]
The camera DSP 20 operates under the control of the control unit 50 while writing / reading data to / from the image memory 30 as necessary. The camera DSP 20 includes a camera processing circuit 21, a still image processing circuit 22, and a moving image processing circuit 23.
[0022]
The camera processing circuit 21 receives the image data from the preprocessing circuit 13 via the memory controller 24 and performs camera signal processing such as AWB (Auto White Balance) processing, AF (Auto Focus) processing, and AE (Auto Exposure) processing. Apply. The still image processing circuit 22 performs compression coding processing on image data on which camera signal processing has been performed in a predetermined still image data format such as a JPEG (Joint Photographic Coding Experts Group) method. Further, the encoded data of the still image supplied from the control unit 50 is decompressed and decoded. The moving image processing circuit 23 performs compression coding processing on image data on which camera signal processing has been performed in a predetermined moving image data format such as an MPEG (Moving Picture Experts Group) method. In addition, the encoded data of the moving image supplied from the control unit 50 is subjected to decompression decoding processing. The memory controller 24 controls reading / writing of data performed between the preprocessing circuit 13, the camera processing circuit 21, the still image processing circuit 22, the moving image processing circuit 23, and the image memory 30.
[0023]

[0024]
The audio processing circuit 40 includes an amplifier, an A / D converter, a D / A converter, a processing circuit that performs compression encoding / decompression decoding, and the like. A microphone 41 and a speaker 42 are connected to the audio processing circuit 40. The audio processing circuit 40 amplifies the audio signal picked up by the microphone 41 and converts it into a digital signal, and further compresses and encodes the audio signal in a predetermined audio data format such as MPEG-AUDIO, and outputs it to the control unit 50. Also, the encoded audio data supplied from the control unit 50 is decompressed and decoded, converted into an analog signal, amplified, and reproduced and output from the speaker 42.
[0025]
The control unit 50 is a microcomputer that controls the entire digital still camera, and has a configuration in which a CPU 51, a RAM 52, a ROM 53, a clock circuit 54, and the like are connected through a system bus 55. The CPU 51 outputs a control signal for controlling each part of the digital still camera by executing a program stored in advance in the ROM 53. The RAM 52 is composed of, for example, a DRAM, and is mainly used as a work area for the CPU 51, such as temporarily storing intermediate results of processing. The ROM 53 is formed of, for example, a flash EEPROM (Electrically Erasable Programmable ROM), and stores various programs executed by the CPU 51, data necessary for processing, and the like. This data includes, for example, screen format data to be displayed on the LCD 90 when a data file to be reproduced is selected. The clock circuit 54 outputs information on the current date, day of the week, and time in response to a request from the CPU 51.
[0026]
A memory card 61 composed of a portable flash memory is detachably connected to the R / W 60 as a recording medium for recording captured image data and audio data. The R / W 60 writes the data supplied from the system bus 55 of the control unit 50 to the memory card 61, and outputs the data read from the memory card 61 onto the system bus 55. In addition, as a recording medium, for example, a writable optical disk, HDD (hard disk drive), or the like may be connected.
[0027]
The external I / F 70 is a communication I / F for connecting the system bus 55 of the control unit 50 to an external device, such as IEEE (Institut of Electrical and Electronics Engineers) 1394 or USB (Universal Serial Bus). It is provided as a wired communication interface or a wireless communication interface using infrared rays or radio waves.
[0028]
The LCD controller 80 generates an image signal to be displayed on the LCD 90 from the image data supplied from the system bus 55 of the control unit 50, supplies this to the LCD 90, and displays an image. In addition, the LCD 90 is provided with a touch panel 100, which allows a user to perform an input operation by pressing the screen with a finger or an indicator. Furthermore, the input unit 101 includes other buttons such as a shutter release button, a lever, a dial, and the like. When an input operation is performed on the touch panel 100 and the input unit 101, a control signal is output from these to the CPU 51.
[0029]
Here, the basic operation of the digital still camera will be described. First, the operation at the time of taking a still image will be described.
Before taking a still image, signals received by the CCD 12 and subjected to photoelectric conversion are sequentially supplied to the preprocessing circuit 13, subjected to CDS processing and AGC processing, converted into digital signals, and supplied to the camera DSP 20. In the camera DSP 20, the supplied image data is subjected to image quality correction processing in the camera processing circuit 21 and supplied to the control unit 50 as image data of a camera through image. In the control unit 50, the input image data is supplied to the LCD controller 80, and a camera through image is displayed on the LCD 90. As a result, the user can adjust the angle of view while viewing the LCD 90.
[0030]
Here, when the shutter release button of the input unit 101 is pressed, the CPU 51 outputs a control signal to the driver 14 to operate the shutter of the optical block. At the same time, the camera DSP 20 is controlled so that one frame of image data supplied from the preprocessing circuit 13 is processed by the camera processing circuit 21 and then stored in the image memory 30 through the memory controller 24. Further, this image data is input to the still image processing circuit 22 to execute compression encoding processing, and the encoded data is supplied to the R / W 60 through the system bus 55. As a result, the data file of the captured still image is stored in the memory card 61.
[0031]
The AF processing and AE processing in the camera processing circuit 21 are performed by receiving a control signal from the CPU 51 when the CPU 51 detects that the shutter release button of the input unit 101 is half-pressed or fully pressed, for example. Is called. Alternatively, it may be performed at any time while displaying a camera-through image. The CPU 51 outputs a control signal to the driver 14 or the preprocessing circuit 13 of the camera block 10 according to the control signal output from the camera processing circuit 21 by executing the AF process or the AE process, and the optical block 11 or the preprocessing. The operation of the circuit 13 is controlled.
[0032]
When shooting a moving image, the image data photoelectrically converted by the CCD 12 and digitized by the preprocessing circuit 13 is processed by the camera processing circuit 21 of the camera DSP 20 and is sequentially stored in the image memory 30. The moving image processing circuit 23 sequentially performs compression encoding processing. At this time, the audio signal picked up by the microphone 41 and supplied to the audio processing circuit 40 is digitized and sequentially subjected to compression encoding processing. Further, by the processing of the CPU 51, moving image and audio encoded data are sequentially multiplexed from the moving image processing circuit 23 and the audio processing circuit 40, respectively, and a moving image file (here, expressed as a moving image file even with audio). Are stored in the memory card 61 sequentially through the R / W 60. Further, only the sound from the microphone 41 can be compressed and encoded by the sound processing circuit 40 and stored in the memory card 61 as a sound file.
[0033]
When the still image, moving image, and audio data files are generated, the CPU 51 acquires the date and time at the time of shooting from the clock circuit 54, adds them to the data file, and stores them in the memory card 61. . For still images, the still image processing circuit 22 further generates reduced image data of the still images and stores them in the memory card 61 in association with the original still images. For a moving image, a still image processing circuit 22 generates a reduced image by using an image for one frame in an arbitrary scene during recording or during recording as a representative image, and similarly associates with the original moving image. The data is stored in the memory card 61. When recording a moving image, it is assumed that the moving image data generated from the recording start operation to the next recording end operation is recorded as one data file. On the other hand, one reduced image is generated.
[0034]
On the other hand, when playing back a still image file stored in the memory card 61, the CPU 51 sends the selected still image file from the memory card 61 to the R / W 60 in response to an operation input from the input unit 101 or the touch panel 100. And is supplied to the still image processing circuit 22 to execute decompression decoding processing. The decoded still image data is supplied to the LCD controller 80, and the still image is reproduced and displayed on the LCD 90.
[0035]
When a moving image file is selected by operation input, it is separated into moving image data and audio data under the control of the CPU 51 and input to the moving image processing circuit 23 and the audio processing circuit 40, respectively. The moving image data decoded by the moving image processing circuit 23 is sequentially supplied to the LCD controller 80, and the moving image is reproduced and displayed on the LCD 90. At the same time, the audio signal decoded and analogized by the audio processing circuit 40 is reproduced and output from the speaker 42. When an audio file is read from the memory card 61, the audio processing circuit 40 performs decompression decoding processing and similarly reproduces and outputs from the speaker 42.
[0036]
The digital still camera captures and collects still image, moving image, and audio data files stored in the memory card 61 through an external I / F 70 under the control of the CPU 51. It can be sent to a device such as a printer. It is also possible to receive a data file transmitted from an external device via a network or the like at the external I / F 70 and record it in the memory card 61, or further reproduce and output this data file.
[0037]
By the way, in the above-mentioned digital still camera, as the storage capacity of the memory card 61 increases, the number of data files to be recorded increases. Therefore, it takes time and effort for the user to find what he / she wants to reproduce from these data files. Is a problem. The above digital still camera can record and play back three types of data files: still images, moving images, and audio, and you want to find only the desired types of data files from the recorded files. There is a great demand.
[0038]
In the present invention, a recorded data file is searched using the generation date (image shooting date, audio recording date, music release date, etc.) as a key, and it is shown that the data file generated on each day exists. By displaying a monthly list display screen in which the identification image is arranged on the calendar on the LCD 90, the search of the data file is facilitated. From this monthly list display screen, by performing a predetermined operation such as selecting an identification image of each day through the touch panel 100, a list display screen by date for displaying a list of identification images of data files generated on each day By selecting the desired identification image from the date list display screen through the touch panel 100, the data file is reproduced and output.
[0039]
In addition, when displaying these list display screens, only data files of a type designated in advance are searched, thereby further facilitating the search. The displayed identification image is an icon or a reduced image of the recorded image so that the contents and type of the recorded data file can be easily recognized visually.
[0040]
Furthermore, although the selection operation for these list display screens is performed using the touch panel 100, the display area of the LCD 90 is reduced with the downsizing of the entire apparatus, and in particular, an erroneous operation easily occurs on the monthly list display screen. By selecting more than once, the screen transitions to the date-based list display screen, and when an identification image selection error occurs, it can be easily re-operated without changing the screen each time. To improve.
[0041]
Hereinafter, the screen transition at the time of reproduction output of the data file as described above will be described with an example of three patterns. First, an example of a setting screen that can be commonly used in these patterns is given.
[0042]
FIG. 2 is a diagram illustrating a screen display example of the display file setting screen.
A display file setting screen 110 shown in FIG. 2 is a setting screen for setting the type of data file to be displayed on each list display screen. The display file setting screen 110 may be displayed in advance prior to the display of the above-described monthly list display screen, for example, or may be displayed by transitioning from the list display screens by month or date.
[0043]
On the display file setting screen 110, selection buttons 111 to 114 are used to specify the type of data file to be displayed. When the selection buttons 111 to 113 are pressed, a moving image file, a still image file, and an audio file are selected. Each is specified. When the selection button 114 is pressed, it is specified to display all files of moving images, still images, and audio. FIG. 2 shows a state in which the selection button 112 has been selected by being pressed by the user's finger or pointing tool. In order to identify the selected icon, for example, the color of the frame changes. Then, after any of these selection buttons 111 to 114 is pressed, the confirmation button 115 is pressed, and the type of the selected data file is confirmed.
[0044]
[First screen transition example]
FIG. 3 is a diagram illustrating a first screen transition example when a data file is selected.
In the first screen transition example, each data file is selected and reproduced by transitioning from the monthly list display screen 120 shown in FIG. 3A to the list display screen 130 by date shown in FIG. Is possible.
[0045]
On the monthly list display screen 120, the presence or absence of the created data file is indicated for each date on the calendar display unit 121. If the created data file exists, an identification image indicating this is displayed. . FIG. 3A shows, as an example, a screen when a still image file is selected as a data file to be displayed on the display file setting screen 110 described above. May 1, 2, 5, 6 Since there are still image files taken on the day, the 14th, and the 28th, the identification images are arranged at the positions of these dates. The identification image placed on each day is a reduced image of the existing still image file, and the reduced image frame has a different color and shape from the other parts so that it can be easily distinguished from the day without the still image file. Is displayed. When there are a plurality of still image files shot on the same day, reduced images of the representative images (for example, those shot at the earliest time) are displayed.
[0046]
The icon 122 indicates that a still image file is designated as the type of data file to be displayed, and changes according to the designated type. The display setting button 123 is a selection button for making a transition to the display file setting screen 110 shown in FIG. 2, and the type of data file to be displayed by making the transition from the monthly list display screen 120 to the display file setting screen 110. Can be changed and returned to the monthly list display screen 120, the type of data file to be searched can be changed and reflected on the monthly list display screen 120.
[0047]
On the monthly list display screen 120, first, an identification image arranged on any date on the calendar display unit 121 is pressed and selected. FIG. 3A shows a state where the identification image of May 5 is selected as an example, and the selected identification image is selected by changing the color or shape of its frame. To be identified. Then, after the identification image is selected, the confirmation button 124 is further pressed, so that a transition is made to the date-based list display screen 130 showing the captured image files for May 5th. In the calendar display unit 121, only the date on which the created data file exists can be selected, and the operation stress when it is selected by mistake is reduced.
[0048]
As shown in FIG. 3B, the list display screen 130 by date displays a list of identification images indicating the data files created on this day in the list display unit 131. Here, the type of the data file to be displayed reflects the setting on the monthly list display screen 120. In this example, since the still image file is set to be displayed, a reduced image of each still image file is displayed as the identification image. In the list display unit 131, since each identification image is displayed in a relatively large size, the certainty of the selection operation is increased. By pressing and selecting the desired identification image, the selected data file is reproduced and output. The
[0049]
When the number of data files created on the same day is larger than the number that can be displayed, the screen can be scrolled using the scroll bar 132 to display the identification image of another data file. An icon 133 indicates the type of data file to be displayed. Further, the display setting button 134 is a selection button for making a transition to the display file setting screen 110 shown in FIG. 2, and makes a transition from the list display screen by date 130 to the display file setting screen 110 to display a data file to be displayed. By changing the type and returning to the date-based list display screen 130 again, it is possible to immediately search for and display other types of data files created on the same day, and to reproduce and output them. The selection button 135 is a selection button for returning to the monthly list display screen 120.
[0050]
Here, in the calendar display unit 121, since the identification image of each day is small, it is relatively difficult for the user to reliably select one identification image. For this reason, for example, when the identification image is immediately pressed to make a transition to the date-based list display screen 130, if an identification image with the wrong date is selected, the screen transitions to the next screen and the correct date is selected. In order to do this, it is necessary to return to the original screen once, which gives stress to the operating user.
[0051]
On the other hand, as described above, after selecting an identification image of an arbitrary date on the calendar display unit 121, it is necessary to further press the confirm button 124. For example, when an incorrect date is selected, the screen is displayed. Without transitioning, another date can be selected on the same screen, reducing operational stress. Further, by changing the color and shape of the frame of the identification image of the selected date, it becomes easier to identify whether or not the correct date has been selected, and the operational feeling is further improved.
[0052]
In addition, since only the type of data file specified on the display file setting screen 110 is searched and displayed on the monthly list display screen 120, the target data file can be found more efficiently. Similarly, only the data file of the type specified on the display file setting screen 110 is displayed on the date list display screen 130 and can be played back, so that the display file setting screen 110 results in the result. The type of data file to be reproduced can be specified in advance, and operability is improved.
[0053]
In addition, the date list display screen 130 displays each identification image larger than the monthly list display screen 120, thereby preventing an error in the selection operation. A more comfortable operation feeling is obtained.
[0054]
FIG. 4 is a flowchart showing the flow of processing until the data file is reproduced and output according to the first image transition example.
When a reproduction operation mode for reproducing a recorded data file is selected by an operation input of a predetermined selection button on the touch panel 100 or a predetermined switch of the input unit 101, the CPU 51 of the control unit 50 stores it in the ROM 53. The predetermined program is read and the following processing is executed.
[0055]
In step S401, the attribute information of the data file in the memory card 61 is searched using the creation date of the data file as a key. The initial value of the creation date as a key is, for example, the current “year” and “month” acquired from the clock circuit 54. If there is a data file created on each day of the corresponding period, the retrieved data The identification image data of the file is acquired for each day and stored in the RAM 52.
[0056]
In this process, only data files of a type designated in advance on the display file setting screen 110 are targeted for search. When a still image file or a moving image file is designated, reduced image data corresponding to the retrieved data file is read from the memory card 61. Alternatively, the retrieved data file itself may be read and reduced image data may be generated by the still image processing circuit 22. When an audio file is designated, image data of an icon indicating the audio file is read from the ROM 53 as the identification image.
[0057]
In step S402, a monthly list display screen 120 is generated using the acquired identification image data, and the LCD controller 80 is controlled to be displayed on the LCD 90. For example, when a still image file or a moving image file is specified, the identification image data acquired in step S401 is decompressed and decoded by the still image processing circuit 22, and the processed image data is read from the ROM 53. By combining with the format data, a monthly list display screen 120 is generated.
[0058]
In step S403, the CPU 51 monitors a control signal from the touch panel 100. When the identification image in the calendar display unit 121 is pressed, the process proceeds to step S405.
