Description

  The present invention relates to a display control technique for improving searchability of images, music songs, and the like managed for each group.

  As a method for efficiently searching for an image recorded on a recording medium in an image device such as a digital camera, for example, so-called thumbnail image display for displaying a total of 16 reduced images of 4 rows and 4 columns as one unit is well known. It has been. In addition, shooting date / time data is attached to the recorded shot image, and internally, file management is performed based on the shooting date / time data. Thumbnail images are also displayed in the order of the shooting date and time, and a search for a desired image is performed while sequentially displaying the thumbnail images.

  However, with the recent increase in capacity of recording media, it has become a problem that efficient search cannot be performed only by managing recorded images sequentially by shooting date and time.

  As a method for solving this problem, a method for managing recorded images in groups has been proposed. For example, the image data read from the recording means in which the image data is recorded is automatically classified into groups that are units for performing the same image processing, and a reduced image of the selected image data is created from each classified group. There has been proposed an image processing apparatus that displays each group, and identifies and displays a group to which a reduced image belongs as a group having a plurality of image data and a group having a single image data (for example, (See Patent Document 1).

In addition, a plurality of grouped image data obtained by shooting processing in the same continuous shooting mode is stored in a memory, and the screen configuration unit displays a list of at least two groups of image data on the same screen. There has also been proposed an image display device that generates display data for display and displays the display data on a screen display unit (see, for example, Patent Document 2).

One image in the group of image rows designated in the reference image is used as a reference image, and the display of the image row of a group other than the group to which the reference image belongs has a shooting condition corresponding to the shooting condition of the reference image. The display position of the image of another group is scrolled so as to be aligned with the display position of the reference image .

  According to the present invention, it is possible to provide a display control device, a display control method, and the like that can easily and efficiently display images and music songs belonging to different groups with respect to group-managed images and music songs. .

  Embodiments of the present invention will be described below with reference to the drawings.

(First embodiment)
First, a first embodiment of the present invention will be described. FIG. 1 is a rear view of a display control apparatus according to the first embodiment of the present invention. This display control device is realized as a digital camera 1.

  As shown in FIG. 1, an LCD (liquid crystal display) display surface is arranged as a display unit 2 on the back of the camera 1, and an XY operation key including a mode dial 3, an up / down key 4a, and a left / right key 4b. 4, operation members such as an OK key 5, a selection button 6, a tele button 7a, a wide button 7b, and a menu button 8 are arranged. A release button 9 is provided on the upper surface.

  The mode dial 3 is for setting the operation mode of the camera 1. The camera 1 has at least a shooting mode for shooting an image and a playback mode for playing back the shot image. The state of the mode dial 3 shown in FIG. 1 is a state when the playback mode is set. is there.

  The XY operation key 4 selects one of a plurality of options arranged in the vertical direction on the display unit 2 (up / down key 4a), or selects one of a plurality of options arranged in the horizontal direction. (Left / Right key 4b). The OK key 5 is for confirming selection of an option selected by the XY operation key 4.

  The XY operation key 4 is used to select one of a plurality of options arranged in the vertical direction or the horizontal direction, whereas the selection button 6 is cyclically displayed every time the button is pressed, for example. One of a plurality of choices is selected.

  The tele button 7a and the wide button 7b are for instructing driving of the lens in the telephoto direction or the wide angle direction. The menu button 8 is used, for example, when displaying a menu or the like for setting the operating environment. The release button 9 is used to give an instruction to record the image data of the subject image displayed on the display unit 2 as a so-called monitor image.

  FIG. 2 is a block diagram showing the configuration of the camera 1.

  When subject light that has passed through the lens 11 enters the image sensor 12, a subject image is formed on the imaging surface. Various controls such as exposure and reading of the image pickup device 12 are performed by the image pickup unit 13, and the image pickup unit 13 converts an image signal output from the image pickup device 12 into a digital signal. This digital signal is transferred to the image processing unit 15 through the image buffer memory 14, and is subjected to ISO sensitivity setting, auto white balance, luminance / color signal generation, gamma processing, etc., and converted into a color image signal of a predetermined format. Is done. This color image signal is transferred to the display processing unit 16 and displayed on the display unit 2 on the back as a monitor image.

  Further, shooting is performed at the timing when the release button 9 is pressed, and the color image signal generated by the image processing unit 15 is taken into the compression / decompression unit 17 and subjected to compression encoding, and the captured image is stored in the image storage memory 18. As recorded. The captured image recorded in the image storage memory 18 is decompressed and decoded by the compression / decompression unit 17 during reproduction, and then supplied to the display processing unit 16 and displayed on the display unit 2 on the back.

  The operation of the camera 1 as described above is integrally controlled by the CPU 19, and the ROM 20 stores various programs describing the control procedure of the CPU 19 and various data used in these programs. Further, a control signal from the operation unit 21 is supplied to the CPU 19. The operation unit 21 detects and notifies operations of the mode dial 3, the XY operation key 4, the OK key 5, the selection button 6, the tele button 7a, the wide button 7b, the menu button 8, the release button 9 and the like shown in FIG. To do.

  FIG. 3 is a file management configuration diagram of the image storage memory 18. As shown in FIG. 3, the image storage memory 18 records captured images in a hierarchical structure in which a top directory is a root directory, folders are placed below the root directory, and files (image data) are stored in the folders. A folder named “album management folder” is a folder for storing information for handling a plurality of photographed images recorded in different folders as belonging to the same album, one for each album. A text file (album text n) is stored. The album here refers to a container for storing photographed images in arbitrary categories so that the photographer can easily manage and search the photographed images later. In this text file, path information indicating the storage location on the image storage memory 18 of each photographed image belonging to each album is listed.

  That is, the camera 1 can handle the captured image stored in the image storage memory 18 in units of groups for each folder or album, and includes a group management unit 101 as a processing unit for managing this group. Various information for group management is stored in the ROM 20. The group management unit 101 corresponds to the CPU 19 that reads and executes a program stored in the ROM 20.

  Next, display control executed by the camera 1 in order to efficiently search for a captured image recorded in the image storage memory 18 in such a manner that it can be handled in groups will be described. This display control is executed by the display control unit 102, and the display control unit 102 corresponds to the CPU 19 that reads and controls execution of a program stored in the ROM 20.

  The display control unit 102 has a function of displaying a reduced image of the captured images managed as a group as described above, that is, displaying a series of image sequences including so-called thumbnail images for a plurality of groups, and switching these in response to a user operation. ing. FIG. 4 is a display example of a screen in which image sequences are arranged in groups for each folder. In the example of FIG. 4, the image sequences composed of the reduced images of each of the four groups “folder.01” to “folder.04” are arranged, and the image sequence “folder.02” is selected. . This group is selected by the left / right key 4b. For example, if the selected group is continuously moved to the right, the “folder.01” at the left end is pushed out of the screen and “folder.05” appears at the right end. Cyclic display switching is performed. Hereinafter, such an operation may be referred to as scrolling.

  In the state where “folder.02” is the selected group, the display control unit 102 sets the reduced image positioned at the top of the reduced images being displayed in the image sequence as the reference image. Then, the display control unit 102 also executes display control for image sequences of groups other than the selected group, based on the shooting date and time of the reference image.

  Here, consider a case where the image sequence of the selected group “folder.02” is scrolled upward by one image by operating the up / down key 4a. That is, this is a case where an operation for switching the reference image from “picture.2-1” to “picture.2-2” is performed.

  The shooting date and time of “picture.2-1” is April 1, 2005, while the shooting date and time of “picture.2-2” is April 5, 2005. Then, the display control unit 102 executes display control corresponding to the switching of the shooting date and time as the reference. More specifically, the display control unit 102 performs automatic scrolling so that a reduced image with a shooting date and time after the shooting date and time of the reference image is positioned at the top of the image row of the group other than the selected group. To do. In FIG. 4, a reduced image surrounded by a thick line is an image taken on April 5, 2005, and FIG. 5 is a display example of the screen after this automatic scrolling.

  As shown in FIG. 5, in contrast to the upward scroll for one image of the selected group “folder.02”, the “folder.01” scrolls upward for three images. In “03”, scrolling upward is performed for four images. In “folder.04”, no scrolling is performed. And by this automatic scrolling that seems to be disordered at first glance, each group has an image sequence starting with April 5, 2005, which is the shooting date and time of “picture.2-1”, which is the new reference image. Will be displayed. If there is no image corresponding to April 5, 2005 in any of “folder.01”, “folder.03”, and “folder.04”, the images closest to that date are arranged after that date. To be displayed.

  In this way, the display control unit 102 performs automatic scrolling for other groups based on the shooting date and time of the image that is newly set as the reference image, not the scroll width (number of images) of scrolling performed for the selected group. The user can search efficiently while aligning the images of a plurality of groups on the time axis.

  6 to 8 are flowcharts showing an operation procedure related to display control when the camera 1 is in the playback mode. FIG. 6 shows a main flow in the playback mode.

  When the playback mode is set by operating the mode button 3, the display control unit 102 first starts a one-frame display process for displaying the captured images one by one on the full screen as an initial state (step A1). Next, the display control unit 102 checks whether or not an instruction to shift to thumbnail display for simultaneously displaying a plurality of reduced images is performed (step A2). If not (NO in step A2), The single frame display process is continued (step A3). This thumbnail display instruction is executed, for example, by pressing the wide button 7b.

  On the other hand, when a thumbnail display instruction is given (YES in step A2), the display control unit 102 subsequently checks whether a group thumbnail display for displaying a plurality of groups of image sequences side by side is instructed as described above. (Step A4) If not performed (NO in Step A4), normal thumbnail display processing is executed in which the respective reduced images are arranged in, for example, a matrix in order of photographing date and time (Step A5). This group thumbnail display instruction is executed, for example, by pressing the wide button 7b again.

  When this group thumbnail display instruction is issued (YES in step A4), the display control unit 102 executes a group thumbnail display process whose detailed procedure is shown in FIG. 7 (step A6).

  When the process shifts to the group thumbnail display process, the display control unit 102 first sets the entire scroll process for evenly scrolling the entire image row of the plurality of groups according to the operation of the up / down key 4a as the initial state as the scroll mode. (Step B1). Next, the display control unit 102 checks whether or not an instruction to switch the group-by-group movement to narrow down the operation target of the up / down key 4a to any group has been performed (step B2), and if it has been performed (YES in step B2). ) A group-by-group scroll process for scrolling only the image row of the selected group in accordance with the operation of the up / down key 4a is executed (step B5). This group-specific movement instruction is executed by, for example, pressing the selection button 6.

  On the other hand, if an instruction to switch to group-specific movement has not been given (NO in step B2), the display control unit 102 then automatically activates another group in conjunction with scrolling of the selected group to be operated by the up / down key 4a. It is checked whether or not an instruction to switch to the group interlocking movement to be scrolled is made (step B4). If not (NO in step B4), the entire scroll process is continued (step B3).

  When an instruction to switch to group interlocking movement is given (YES in step B4), the display control unit 102 executes interlocking scroll processing whose detailed procedure is shown in FIG. 8 (step B6). This group interlocking movement instruction is performed by, for example, pressing the selection button 6 twice.

  In the interlocking scroll process, the display control unit 102 first performs initial display, for example, by arranging a predetermined number of groups of image rows from the top (step C1), and when the left / right key 4b is operated (YES in step C2). The selected group is changed (step C3). On the other hand, if the up / down key 4a is operated (YES in step C4), scrolling of the image row of the selected group is executed (step C5).

  After scrolling the image row of this selected group, the display control unit 102 checks whether or not the current operating environment setting is automatic switching (step C6). If yes (YES in step C6), then, The processing from Step C7 to Step C11 for automatically scrolling the image rows of other groups is immediately executed. Whether or not this automatic switching is performed can be set along a menu displayed when the menu button 8 is pressed.

  In order to perform this automatic scrolling, the display control unit 102 first reads the date of the reference image in the image sequence of the selected group (step C7), and determines this date as the reference date for automatic scrolling (step C8). Then, the display control unit 102 determines an image to be displayed in another group based on the reference date (step C9), reads the determined image (step C10), and reads the image group The image sequence of the other group consisting of is displayed (step C11). As a result, automatic scrolling of other groups is performed in conjunction with scrolling of the selected group. It should be noted that the timing of the display switching of the selected group and the display switching of another group may be performed simultaneously.

  On the other hand, if the current operating environment setting is not automatic switching (NO in step C6), the display control unit 102 does not immediately execute automatic scrolling of another group after scrolling the selected group, for example, At the timing when a switching instruction is made by pressing the OK button 5 (YES in step C12), the above-described processing of steps C7 to C11 for automatic scrolling is executed.

  By the way, as described above with reference to FIGS. 4 and 5, the image located at the top of the image row of the selected group is set as the reference image, and the image row of the other group other than the selected group is set as the shooting date and time of this reference image. Although an example of automatic scrolling so as to be aligned has been described, the present invention is not limited to this. For example, as shown in FIGS. 9 and 10, an image located at the bottom of the image row of the selected group may be used as a reference. That is, when the image sequence of the selected group “folder.02” is scrolled down by two images by operating the up / down key 4a, the display control unit 102 changes the reference image from “picture.2-5” to “picture.2”. Recognize that it has switched to 2-3. Then, since the shooting date and time of the reference image is switched from April 8, 2005 to April 5, 2005, the display control unit 102 displays the image at the bottom of the image row of the group other than the selected group. Automatic scrolling is executed so that a reduced image with a shooting date and time before the shooting date and time of the reference image is located. In FIG. 9, a reduced image surrounded by a thick line is an image taken on April 5, 2005, and FIG. 10 is a display example of the screen after this automatic scrolling. In the image sequence of each group, the images in the group are arranged cyclically. For example, when the image taken on April 5, 2005 is the first image, such as “folder.04”, The last image is displayed on the upper stage.

  In addition, as shown in FIGS. 4, 5, 9, and 10, the example in which the image rows of each group are arranged side by side so as to be scrollable in the vertical direction has been described above. For example, as shown in FIGS. 11 and 12, a plurality of groups of image rows may be arranged side by side so that the image rows of each group can be scrolled in the horizontal direction.

  In the state of FIG. 11, when the image sequence of the selected group “folder.02” is scrolled leftward by one screen by operating the left / right key 4b, the display control unit 102 determines that the reference image is “picture.2-1”. From the selected group so that the reduced image after the shooting date and time after April 5, 2005, which is the shooting date and time of this reference image, is located in the leftmost part. Automatic scrolling of image rows of other groups other than other groups is executed. Even when scrolling in the left-right direction is possible, the reference image may be a reduced image positioned at the rightmost part in the image row of the selected group. Furthermore, the user may be able to arbitrarily set the display direction of the image sequence of each group and whether the reference image is up or down or left and right along a menu displayed by pressing the menu button 8.

  Further, as described above, in the camera 1, by the function of the group management unit 101, the captured image stored in the image storage memory 18 can be handled not only for each folder but also for each group for each album. Therefore, as shown in FIG. 13 and FIG. 14, the above-described automatic scrolling method can naturally be applied to a case where image sequences for each album are displayed side by side. That is, in the state shown in FIG. 13, the image sequence of the selected group “Album3” is changed from “picture.1-6” on April 1, 2005 to the shooting date April 5, 2005 by operating the up / down key 4a. When the reference image is switched to “picture.1-14”, automatic scrolling is performed so that a reduced image of the shooting date and time after April 5, 2005 is positioned at the top of the image row of the group other than the selected group. Execute. In FIG. 13, a reduced image surrounded by a thick line is an image taken on April 5, 2005, and FIG. 14 is a display example of the screen after this automatic scrolling.

  As described above, the camera 1 can easily and efficiently display images belonging to different groups with respect to the group-managed images.

  Recently, the longitude and latitude of the current position can be easily obtained using GPS (global positioning system), so instead of using the shooting date and time as a reference, the longitude and latitude of the place where each image was shot is used as the reference. It is also possible. In this way, for example, the images of the selected group are automatically scrolled so that the images of the other groups other than the selected group are also in the vicinity of the shooting location of the reference image in synchronization with the view from the north to the south. It becomes possible.

(Second Embodiment)
Next explained is the second embodiment of the invention. FIG. 15 is a block diagram showing a configuration of a display control apparatus according to the second embodiment of the present invention. This display control device is realized as a music playback device.

  In the storage memory 31, for example, music data that is compression-coded including attribute data such as a jacket image, an announcement date, and a performer is stored in units of groups. The attribute data is displayed as a list on the display unit 2 by the display processing unit 32 by arranging a plurality of groups as a song list. When one of the lists is selected, the music data is read from the storage memory 31 and reproduced by the audio decompression unit 34, and is output as a music song from the audio output unit 36 via the buffer memory 35. .

  The operation of the music reproducing apparatus is integratedly controlled by the CPU 37, and the ROM 38 stores various programs describing the control procedure of the CPU 37 and various data used in these programs. A CPU 37 that reads and controls execution of a program stored in the ROM 38 corresponds to the group management unit 201 and the display control unit 202. Further, a control signal from the operation unit 39 is supplied to the CPU 37.

  The music playback apparatus displays a list of music data attribute data as a song list, and when a vertical scroll is instructed from the operation unit 39, display control is performed to automatically scroll a song list of a group other than the selected group. I do. FIG. 16 is an example of a song list display of music data grouped by performer (Artist). The selected group is based on the announcement date of the music data located at the top of the song list of “Artist2” of the selected group. Automatically scroll the song list of other groups other than. In the “Artist4” group, since there is no song corresponding to the date and time, the oldest song is displayed at the top. On the other hand, FIG. 17 is an example of music data song list display grouped by age, based on the name of the music data performer located at the top of the song list of “70s Best Album” of the selected group. , Automatically scrolls the song list of other groups than the selected group (in alphabetical order, for example).

  18 and 19 are flowcharts showing an operation procedure related to display control of the music playback device. FIG. 18 shows a main flow of the group song list display process.

  First, the display control unit 202 sets, as an initial state as a scroll mode, an overall scroll process for evenly scrolling a plurality of groups of music lists according to a scroll operation (step D1). Next, the display control unit 202 examines whether or not an instruction to switch to the group-specific movement for narrowing down the target of the scroll operation to any group is performed (step D2), and if it is performed (YES in step D2), A group-by-group scroll process for scrolling only the image sequence of the selected group according to the scroll operation is executed (step D5).

  On the other hand, if an instruction to switch to group-specific movement has not been given (NO in step D2), the display control unit 202 subsequently automatically scrolls other groups in conjunction with the scrolling of the selected group to be scrolled. It is checked whether or not an instruction to switch to group-linked movement has been made (step D4). If not (NO in step D4), the entire scroll process is continued (step D3).

  When an instruction to switch to group interlocking movement is given (YES in step D4), the display control unit 202 executes interlocking scroll processing whose detailed procedure is shown in FIG. 19 (step D6).

  In the linked scroll process, the display control unit 202 first performs initial display, for example, by arranging a predetermined number of groups of music lists from the top (step E1), and when a horizontal scroll operation is performed (YES in step E2), the selection is performed. The group is changed (step E3). On the other hand, when the vertical scroll operation is performed (YES in step E4), scrolling is performed for the music list of the selected group (step E5).

  After scrolling the image row of this selected group, the display control unit 202 checks whether or not the current operating environment setting is automatic switching (step E6). If yes (YES in step E6), then, Steps E7 to E15 for automatically scrolling the music list of another group are immediately executed.

  In order to perform this automatic scrolling, the display control unit 202 first checks whether the grouping is performed by player or age (step E7), and if it is by player (step E7). YES), the announcement date and time of the reference music data (reference song) positioned at the top in the song list of the selected group is read (step E8), and this date and time is determined as the reference date and time for automatic scrolling (step E9). Then, the display control unit 202 determines music data to be displayed in the song list in another group based on the reference date and time (step E10).

  On the other hand, if grouping by age is performed (NO in step E7), the display control unit 202 reads out the performers of the reference music data (reference song) in the song list of the selected group (step E11), The player is determined as a reference name for automatic scrolling (step E12), and music data to be displayed in the song list in other groups is determined (step E13).

  Then, the display control unit 202 reads the attribute data of the music data determined as described above (step E14), and displays a song list of another group including the read attribute data group (step E15). As a result, automatic scrolling of other groups is performed in conjunction with scrolling of the selected group.

  On the other hand, if the current operating environment setting is not automatic switching (NO in step E6), the display control unit 102 does not immediately execute automatic scrolling of the other group after scrolling the selected group, but the user. At the timing when the switching instruction operation is performed (YES in step E16), the above-described steps E7 to E15 for automatic scrolling are executed.

  As described above, like the camera of the first embodiment, this music playback device can easily and efficiently display a list of music songs belonging to different groups for music songs managed in groups.

  The software program for executing the above functions is supplied to the CPU 19 of the first embodiment or the CPU 37 of the second embodiment, and the CPU 19 or the CPU 37 operates according to the supplied program to perform the functions of the above embodiments. Those realizing the above are also included in the scope of the present invention. That is, the software program itself realizes the functions of the above-described embodiments, and the program itself constitutes the present invention.

  These programs may be stored in the form of a recording medium other than the ROM 20 of the first embodiment or the ROM 38 of the second embodiment, and may be read out and executed from there. Furthermore, the program may be stored in a recording medium that can be attached to and detached from the camera or the music playback device.
