JP 2004-078384 A

  Some moving image reproducing devices or image editing devices display an index screen that displays a list of representative images of a plurality of recorded moving images as reduced images (thumbnail images). The user selects the thumbnail image by a key operation or the like and designates a reproduction target or an editing target.

  In this main list display, a predetermined number of thumbnail images are displayed side by side in the same size on one screen. Since the screen size is limited, the thumbnail image of the latter is smaller than that of the former in the case of listing 6 images and the case of listing 24 images.

  In order to make the thumbnail image as large as possible, the space for displaying other information in the screen is often small, and the recording time display of each cut is often omitted.

  On the other hand, there is a folder list display as another example of the list display, and Patent Document 1 describes changing the size of a folder icon based on the number of files / data amount in the folder. In this display example, even if there is no numerical display of the number of files / data amount in the folder, the relative amount can be estimated from the size of the folder icon.

  In the conventional example, on the index screen, the user has no choice but to read the recording time display in order to obtain the recording time length information. For example, in the example of displaying a list of 6 thumbnail images, if the length of the recorded moving image indicated by each thumbnail image is all 10 minutes, the entire index screen indicates a 60-minute moving image. On the other hand, when the length of the recorded moving image indicated by each thumbnail image is 4 seconds, the entire index screen indicates a moving image of 24 seconds.

  Therefore, when the display of the recording time is omitted in the conventional example, the user cannot distinguish between a cut with a long recording time and a cut with a short recording time on the index screen. Further, in order to specifically check the recording time of each cut, it is necessary to select the corresponding thumbnail image and display the recording time information.

  It is an object of the present invention to present a display control apparatus, method and program for eliminating such inconvenience, and a recording medium storing the display control program.

It is a schematic block diagram of one Example of this invention. It is an example of the index screen produced | generated by a present Example. It is an index screen display generation flowchart of a present Example.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a schematic block diagram of an image reproducing apparatus incorporating an embodiment of a display control apparatus according to the present invention.

  The CPU 101 is an arithmetic processing unit that controls the entire moving image playback apparatus. The CPU 101 executes various programs and controls display on the display unit 104 in accordance with instructions from the user input from the operation input unit 105 and the like. A ROM (Read Only Memory) 102 stores processing procedures of the CPU 101 (for example, startup processing and basic input / output processing of the moving image playback apparatus, and processing programs described later). The ROM 102 further stores character data for display, image data, and the like. A RAM (Random Access Memory) 103 is used as a work area of the CPU 101.

  The display unit 104 serves as a graphic user interface and displays images and display items to be described later. The operation input unit 105 is a unit that receives instructions from the user, and includes various keys as hardware, software keys displayed on the display unit 104, a remote controller, and the like. The user can operate the video playback device by using the operation input unit 105.

  The moving image storage unit 106 includes a flash memory, an optical disk, a magnetic disk, a magneto-optical disk, and the like, and can read and write image data.

  The image processing unit 107 synthesizes the moving image data read from the moving image storage unit 106 and the character data and image data read from the ROM 102 according to an instruction from the CPU 101 and displays them on the display unit 104.

  The CPU 101, ROM 102, RAM 103, display unit 104, operation input unit 105, moving image storage unit 106 and image processing unit 107 communicate with each other via an internal bus 111.

In the present embodiment, the size or size of the thumbnail image displayed on the index screen, which is a moving image list display screen, is increased as the moving image length or recording time increases. FIG. 2 shows an example of an index screen generated by this embodiment. In principle, five thumbnail images are juxtaposed side by side and arranged vertically in two rows, and the horizontal and vertical size of each thumbnail is increased stepwise as the recording time is increased. The coordinate X1 is a reference coordinate of the thumbnail image arranged on the leftmost side. The coordinate Y1 is a reference coordinate that is the upper side of the thumbnail image arranged in the first column, and the coordinate Y1 is a reference coordinate that is the upper side of the thumbnail image arranged in the second column. That is, the Y coordinate represents the number of rows (the number of stages) or rows when a plurality of images are displayed in a matrix on one screen. The X coordinate represents the number of columns or columns when a plurality of images are displayed in a matrix on one screen. For example, an image displayed in the second column of the third row when displayed in 4 rows and 6 columns is handled as Y coordinate = 3 and X coordinate = 2. In the present embodiment, the number of columns in different rows does not necessarily match.

  FIG. 3 is an index screen display generation flowchart according to this embodiment. The CPU 101 executes program software loaded from the ROM 102. In FIG. 3, the cut recording time is compared with a reference value (in this example, 5 seconds), and the thumbnail images are displayed in two levels. The thumbnails are sequentially drawn on the index screen from the upper left of the screen. The size of the thumbnail of a moving image whose recording time exceeds 5 seconds is doubled both vertically and horizontally than the thumbnail image of a moving image whose recording time is 5 seconds or less. The CPU 101 functions as a thumbnail image generating unit or a thumbnail image generating function for generating a thumbnail image having a size determined by a method described later for each cut.

  10 cuts in which the recording time of the movie is 5 minutes, 4 seconds, 4 seconds, 4 seconds, 4 seconds, 4 seconds, 5 minutes, 4 seconds, 4 seconds, 4 seconds in order from the cut to be displayed first. Is stored in the moving image storage unit 106.

  The CPU 101 sets the first reference Y coordinate (= Y1) (S302) and sets the first reference thumbnail X coordinate (= X1) (S303).

  Next, as a recording time determination means or a recording time determination function, the CPU 101 compares the recording time of the cut to be displayed with a reference value of 5 seconds (S304). If the recording time is 5 seconds or less (S304), the CPU 101 sets the size to small (S309), otherwise (S304) sets the size to large (S305). Since the recording time corresponding to the first thumbnail image in the first row is 5 minutes, the size of this thumbnail image becomes large.

  Usually, the image of the corresponding first frame of the moving image cut is used as a representative image, and the size of the representative image is reduced to generate a thumbnail image having a large size or a small size. Alternatively, a thumbnail image having a uniform large size and a part of the thumbnail image cut out or a pixel thinned out on average may be used as a small size thumbnail image.

  The CPU 101 determines whether or not the result of adding the horizontal width of the thumbnail image to be drawn to the set X coordinate exceeds the thumbnail displayable area. (S306). That is, it is determined whether the thumbnail images whose sizes have been determined in steps S305 and S309 can be displayed side by side.

  When display is possible (S306), the CPU 101 renders a thumbnail at a position on the screen of the display unit 104 corresponding to the coordinates as a thumbnail image display means or thumbnail image display function (S307). That is, the CPU 101 functions as a thumbnail image display unit or a thumbnail image display function for displaying a plurality of moving image thumbnail images on the list display screen. The CPU 101 adds the width of the thumbnail image drawn on the X coordinate and the gap between the next thumbnail image (S308), and returns to the next cut recording time determination (S304).

  Similarly, for two or more recorded moving images, the CPU 101 determines the size (S304, S305, S309), and determines the display possibility of side by side (S306). The thumbnail images 1-2 to 1-5 of the second to fifth recorded images are small in size, and as shown in FIG. 2, these thumbnail images 1-2 to 1-5 are designated as the first. They can be displayed side by side on the same line.

  Although the size of the sixth thumbnail image is small, in the display possibility determination (S306), it becomes impossible to display in the first row (S306). At this time, since the second stage is not reached (S310), the CPU 101 sets the number of stages to 2, and sets the second stage reference Y coordinate (= Y2) (S312). Then, the CPU 101 sets the reference X coordinate (= X1) of the first thumbnail image 1-1 in the first row (S303). The CPU 101 displays the sixth thumbnail image 1-6 at the second set position on the display unit 104. Thereafter, similarly, the sizes of the seventh and subsequent thumbnail images 1-7 to 1-10 are determined and displayed side by side. The second thumbnail image 1-7 in the second row has a recording time of 5 minutes and exceeds the reference time of 5 seconds, so the size becomes large.

  If the second row cannot be displayed (S306, S310), the CPU 101 ends the index screen generation process.

  By displaying thumbnail images of moving images with a short recording time in a relatively small size, more thumbnail images can be displayed on one screen. The length of the recording time can be roughly recognized by the size of the thumbnail image, and the listability with respect to the recording time is improved. That is, short cuts that are considered to be not very important can be displayed in a small size, and more cuts can be displayed on one screen, so that the listability is improved. In addition, since the cut with a longer recording time is displayed larger than the shorter cut, it is possible to check the thumbnail in more detail for the longer cut that is assumed to be an important cut compared to the shorter cut.

Furthermore, it is now possible to determine whether the video is a short cut of 5 seconds or less or a longer cut by simply looking at the thumbnail on the index screen. Further, it is possible to distinguish between a cut with a long recording time and a short cut without displaying the recording time of each moving image cut.

  Although an example in which the size of the thumbnail image is controlled in two steps has been described, the recording time of the cut may be classified more finely and the number of steps of the thumbnail image size may be increased. By doing so, it becomes easier to recognize the recording time of the cut more finely.

  Although the horizontal display position (X coordinate) is changed according to the size of the thumbnail image, the vertical display position (Y coordinate) may be similarly changed according to the size of the thumbnail image. Of course, both display positions may be changed.

  The following functions may be provided on the index screen. In other words, all small thumbnails (short cuts) or only large thumbnails (long cuts) can be selected. Then, various operations such as deletion, protection (protection), addition of attribute information such as favorite level and classification information, print designation, transmission designation, and continuous reproduction can be performed on the selected cut.

  Only small thumbnails (short cuts) can be deleted. This may be because a cut of several seconds is often considered to be an unnecessary cut due to reasons such as shooting mistakenly in the still image shooting mode or wrong shooting timing. Therefore, by providing a function for selecting and deleting only small thumbnails, it is possible to delete short cuts that are considered unnecessary, and the convenience is improved.

Play only small thumbnails (short cuts) continuously. When each one plays a short cut, short for immediate playback is finished Mau but continuous playback by default, such troublesome is eliminated. To watch multiple cuts, playback instructions are required many times, but providing this function saves this effort. If it is short, it will finish watching even if it is continuous.

  A jump selection button for sequentially selecting only thumbnails of a predetermined size is provided. For example, a large thumbnail jump button for sequentially selecting only large thumbnails and a small thumbnail jump button for sequentially selecting only small thumbnails are provided.

  In the above embodiment, part or all of the functions can be realized by a program on a computer (CPU). Such a program, for example, a display control program, is conveyed by a CD-ROM or other recording medium, Can be installed.

  The present invention is also realized by executing the following processing. That is, software (program) that realizes the functions of the above-described embodiments is supplied to a system or apparatus via a network or various storage media, and a computer (or CPU, MPU, etc.) of the system or apparatus reads the program code. It is a process to be executed. In this case, the program and the storage medium storing the program constitute the present invention.
