[User interface overview]
Next, a user interface of the display control apparatus according to the embodiment will be described.

  FIG. 3 is an explanatory diagram illustrating a user interface of the display control apparatus according to the embodiment.

  As shown in FIG. 3, in the rectangular content browsing window 59, a rectangular moving image window 61 displays a moving image showing a lecturer's lecture. A slide used by the speaker is displayed in the rectangular still image window 63. The display content of the slide changes in synchronization with the progress of the lecturer. The timing of this change is the same as the actual lecture. Speech of the lecture, background music, sound effects, etc. are also output via the sound device 27.

  Below the windows 61 and 63, a strip-shaped reduced image sequence display area 41a for displaying a list of reduced image sequences 41 of slides to be reproduced is provided. A list of reduced image sequences 41 of slides to be reproduced is displayed in the reduced image sequence display area 41a.

  The reduced image sequence 41 of the slide is formed by connecting a plurality of reduced images 42 in parallel. The size of each reduced image 42 is determined by a predetermined longitudinal direction size L of the reduced image row display area 41 a and the number of slides included in the reduced image row 41. The size of the reduced image 42 included in the reduced image sequence 41 when the pointer 32 is not positioned on any reduced image 42 in the reduced image sequence 41 is hereinafter referred to as a reduced image size.

  In this embodiment, when the user operates the button of the mouse 31 to position the pointer 32 on any one of the reduced images 42 in the reduced image sequence 41, the reduced image 42 is enlarged and displayed as a noticed image. Is done. At this time, the enlarged image size of the noticed image T is sufficiently larger than the reduced image size.

  Further, when the user selects (clicks) the button of the mouse 31 while maintaining the pointer position, the image of the slide is displayed on the still image window 63. At the same time, the moving image starting from the corresponding clip portion of the moving image data synchronized with the selected slide is reproduced and displayed on the moving image window 61.

  Note that as the plurality of images included in the reduced image sequence 41, a plurality of still image clips fragmented at appropriate time intervals in the moving image data may be employed. In this case, when the pointer 32 is positioned on any one of the still image clips, the still image clip is enlarged and displayed as an attention image. When the user selects (clicks) the button of the mouse 31 while maintaining the pointer position, the still image clip image is displayed in the still image window 63. At the same time, a moving image starting from the corresponding portion of the moving image data synchronized with the selected still image clip is reproduced and displayed on the moving image window 61.

Below the reduced image row display area 41a, a button 65 for stopping / rewinding / fast-forwarding the conference content, and a time for displaying the progress of the conference content along the time axis. Line 67 is provided. Reference numeral 69 is a slide material switching point on the timeline 67.
[Operation of display control device]
Next, the operation of the display control apparatus according to the embodiment will be described.

  FIG. 4 is a flowchart illustrating the operation of the display control apparatus according to the embodiment. FIGS. 5A and 5B are operations of the display control apparatus according to the embodiment when the pointer is positioned on the target image. FIGS. 6A and 6B are diagrams for explaining the operation of the display control apparatus according to the embodiment when the pointer instruction position of the target image is moved backward, and FIG. 7A. , (B) are diagrams for explaining the operation of the display control apparatus according to the embodiment when the pointer instruction position of the target image is moved in the forward direction.

  As a premise, it is assumed that video data, slide image data related to the video data, and conference content including the synchronized playback data have been downloaded, and the conference content playback operation has been performed.

  As shown in FIG. 4, in step S11, a total slide quantity acquisition process is executed. This process is executed by referring to the “slide total quantity” information described in the XML file 55.

  In step S12, an enlarged slide size acquisition process is executed. This process is executed by referring to the “enlarged slide size” information described in the XML file 55. This “enlarged slide size” information includes an enlargement ratio (enlarged image size is acceptable) with respect to the reduced image size of the target slide, and an overall mountain shape by gradually reducing the enlargement ratio as the target slide is enlarged. And the target slide and the semi-enlarged slide group (hereinafter, the target slide and the semi-enlarged slide group are collectively referred to as the expanded slide group) with respect to the number of the semi-enlarged slide groups forming the image size Occupancy rate).

  In step S13, an image size calculation process is executed. This process includes a reduced image size calculation process and a fine image size calculation process.

  In the reduced image size calculation process, the size (reduced image size) of each reduced image 42 in the reduced image sequence 41 when the pointer 32 is not positioned on the reduced image 42 in the reduced image sequence 41 is obtained. Refers to processing.

  The fine image size calculation process is a process for obtaining the size (fine image size) of the fine image 43 in the reduced image sequence 41 when the pointer 32 is positioned on the reduced image 42 in the reduced image sequence 41. .

  The image size calculation processing includes the “total number of slides” information acquired in step S11, the “enlarged slide size” information acquired in step S12, the longitudinal size L of the reduced image sequence display area 41a set in advance, It is executed based on.

  This will be described with reference to FIG. In the reduced image size calculation process, since the “total number of slides” is “15”, an operation for proportionally allocating the longitudinal size L of the reduced image row display area 41a to each of the 15 images is performed (1 sheet). The size of the reduced image size can be obtained by about 6.7% of the size L in the longitudinal direction, and the reference is the size L in the longitudinal direction.

  In the fine image size calculation process, the “total number of slides” is “15”, and the number of the enlarged slide group is 7 (including the target image) in the “enlarged slide size”. Assume that the group occupancy is 75%. In this case, the number of slides related to the reduced image is (15-7) = 8. A fine image size can be obtained by performing a calculation (about 3.1% per sheet) for proportionally distributing 25% of the size L in the longitudinal direction of the reduced image row display area 41a on these eight sheets.

  In step S14, the reduced image sequence 41 is normally displayed. In executing the normal display process, the reduced image size obtained in step S13 is referred to.

  In step S15, the presence / absence of a pointer instruction for the reduced image sequence 41 is determined. This determination is performed by referring to the detection result of the position detection unit 35 related to whether or not the pointer 32 displayed on the display screen of the display 33 is positioned on the image of the reduced image sequence 41. Executed.

  As a result of the determination in step S15, when it is determined that there is no pointer instruction for the reduced image sequence 41, the CPU 13 returns the flow of processing to the upstream side of step S15 and repeatedly executes the following processing.

  On the other hand, as a result of the determination in step S15, when it is determined that there is a pointer instruction for the reduced image sequence 41, the display control unit 37 executes an enlarged display process of the target image. That is, the display control unit 37 enlarges the image of interest T for which the pointer instruction has been given, from other images, and displays the reduced image sequence 41 on the display screen of the display 33 (step S16).

  The “other images” referred to in the present invention means all images except the target image T. Specifically, as shown in FIGS. 5A and 5B, the reduced image 42 having the reduced image size, the fine image 43 having the fine image size, and each image 77a belonging to the semi-enlarged slide group. , 77b correspond to the “other images”.

  The enlarged display process in step S16 will be described with reference to FIGS. 3, 5A and 5B.

  The example shown in FIG. 5A shows an enlarged display mode when the pointer 32 is positioned on the “eighth image” in the reduced image sequence 41 shown in FIG.

  Along with the enlarged display of the target image T (eighth image), a range that exceeds a predetermined interval (three frames in the example of FIG. 5A) from both sides of the target image T in the reduced image sequence 41. The fine image 43 existing in is displayed finely with the fine image size obtained in step S13. The predetermined interval is described in advance in the XML file 55.

  As the attention image T (eighth image) is enlarged and displayed, the images 77a and 77b existing within a predetermined interval from both sides of the attention image T in the reduced image sequence 41 have the fine image size. The image 43 is enlarged and displayed.

  In particular, the images 77a1 and 77b1 existing immediately on both sides of the target image T are smaller than the target image T, but are enlarged and displayed as compared with the reduced image 42 having the reduced image size.

  In addition, the images 77a2 and 77b2 that are in the immediate vicinity of both sides of the images 77a1 and 77b1 are smaller than the images 77a1 and 77b1, but are displayed larger than the reduced image 42 of the reduced image size.

  The images 77a3 and 77b3 that are immediately adjacent to both sides of the images 77a2 and 77b2 are smaller than the images 77a2 and 77b2, and are approximately the same as or slightly smaller than the reduced image 42 of the reduced image size. Is displayed. However, the images 77a3 and 77b3 are enlarged and displayed as compared with the fine image 43.

  In short, with the enlarged display of the target image T (eighth image), within a predetermined interval (three frames in the example of FIG. 5A) from both sides of the target image T in the reduced image sequence 41. The images 77a and 77b existing in the range are displayed with a mountain shape in which the enlargement is gradually reduced with the attention image T as a vertex.

  A dead zone 73 exists in the display area 71 of the target image T (eighth image). As long as the pointer 32 is positioned within the dead zone 73, the image of interest T (eighth image) is continuously enlarged and displayed.

  The dead zone 73 of the target image T corresponds to the target image T when the pointer 32 is not positioned on the reduced image sequence 41, as shown in comparison with FIG. It is set based on the display area occupied by the reduced image. Specifically, in the example of the target image T (eighth image), the dead zone 73 is occupied by a reduced image (eighth image) corresponding to the target image T as shown in FIG. The position and front / rear length of the display area 41b are set to be the same.

  In step S17, it is determined whether or not the pointer instruction position has moved. This determination is based on whether or not the pointer 32 displayed on the display screen of the display 33 is positioned in the display area 71 of the target image T and within the dead zone area 73. This is executed by referring to the detection result of the position detection unit 35.

  As a result of the determination in step S15, when it is determined that the pointer 32 is positioned within the display area 71 of the target image T and within the dead zone area 73, the CPU 13 performs the processing flow. Returning to the upstream side of step S17, the following processing is repeatedly executed.

  On the other hand, as a result of the determination in step S17, when it is determined that the pointer 32 is within the display area 71 of the attention image T but is out of the range of the dead zone 73, the display control unit 37 sets a new attention image. The enlarged display process is executed. That is, the display control unit 37 regards the image adjacent to the off-position side as the new attention image NT, and instead of the image 71 that was the attention image T, enlarges it from the other images, The reduced image sequence 41 is displayed on the display screen of the display 33.

  The new attention image enlargement display process will be described with reference to FIGS. 6 (A) and 6 (B) and FIGS. 7 (A) and 7 (B).

  In the example shown in FIGS. 6A and 6B, the pointer 32 is positioned in a state where the pointer 32 is positioned within the dead zone area 73 of the “eighth image” in the reduced image sequence 41. The enlarged display transition mode when moving to the rear side (9th image side) is shown. In this example, instead of the image 71 that is the attention image T, a new attention image (9th image) 75a is newly enlarged and displayed.

  In magnifying and displaying the new image of interest NT instead of the image of the image of interest T, the switching is displayed in a manner that ensures visual smoothness. Specifically, in the image that is the attention image T, the image gradually decreases from the enlarged image size to the image 77a1 of the semi-enlarged image size over time. At the same time, the new attention image NT gradually increases from the image 77b1 of the semi-enlarged image size to the enlarged image size over time.

  Therefore, the transition of the image of interest can be displayed in a manner that ensures visual smoothness.

  As the new image of interest NT is enlarged and displayed instead of the image of the image of interest T, a predetermined interval from both sides of the image of interest NT in the reduced image sequence 41 (example in FIG. 6A) The images 77a and 77b existing within the range of 3 frames) are displayed with a mountain shape in which the enlargement is gradually reduced with the target image NT as a vertex.

  On the other hand, in the example shown in FIGS. 7A and 7B, the pointer 32 is positioned in a state where the pointer 32 is positioned within the dead zone area 73 of the “eighth image” in the reduced image sequence 41. The enlarged display transition mode when 32 moves to the front side (7th image side) is shown. In this example, instead of the image 71 that was the attention image T, a new attention image (seventh image) 75b is newly enlarged and displayed.

  When the new image of interest NT is enlarged and displayed instead of the image of the image of interest T, the switching is performed in a display manner that ensures visual smoothness as described above. Therefore, the transition of the image of interest can be displayed in a manner that ensures visual smoothness.

  As the new image of interest NT is enlarged and displayed instead of the image of the image of interest T, a predetermined interval from both sides of the image of interest NT in the reduced image sequence 41 (example in FIG. 6A) In the same manner as described above, the images 77a and 77b existing in the range within 3 frames) are displayed with a mountain shape in which the enlargement is gradually reduced with the target image NT as a vertex.

  As described above, according to the display control apparatus 11 according to the embodiment of the present invention, the display control unit 37 is in the display area of the enlarged attention image T and exists in the display area. When the position detector 35 detects that the pointer 32 is located outside the dead zone 73 that maintains the enlargement of the target image T regardless of the position of the pointer 32, it is adjacent to the side where the pointer 32 is located. The image to be viewed is regarded as a new attention image NT, and instead of the image 71 that was the attention image T, the reduced image sequence 41 is displayed on the display screen in a larger size than the other images. It is possible to realize a display control mode in which content can be searched with a simple operation.

  In the display control apparatus according to the above embodiment, the dead zone 73 of the target image T may be configured based on the display region occupied by the reduced image corresponding to the target image T.

  With this configuration, each image can be sequentially enlarged and displayed while seamlessly straddling the adjacent images in the reduced image sequence 41. Therefore, it is possible to realize a display control mode excellent in intuitive operation in the sense that the pointer moves smoothly between adjacent adjacent images and does not cause a sense of incongruity.

  Further, the display control unit 37 may adopt a configuration in which the reduced image sequence 41 is displayed on the display screen in a mountain shape with the enlargement gradually reduced with the attention image T as a vertex.

  With this configuration, the image T of the reduced image sequence 41 has a peak shape of the image of interest T, and a mountain-like shape in which the enlargement is gradually reduced, and is within a predetermined interval of the images on both sides of the image of interest T. Since the semi-enlarged images 77a and 77b existing in the range are enlarged and displayed as compared with the fine image 43 of the fine image size, it is possible to improve the apparent graspability of the semi-enlarged image. In particular, since the images 77a1 and 77b1 existing immediately on both sides of the target image T are displayed with a size that is sufficiently enlarged as compared with the reduced image 42 of the reduced image size, it is possible to remarkably improve the apparent graspability. it can.

The pointer 32 deviates from the dead zone 73 within the display area of the enlarged attention image T, which exists in the display area and maintains the enlargement of the attention image T regardless of the position of the pointer 32. Is detected in the position detection step, the image adjacent to the off-position side is regarded as a new attention image NT, and instead of the image that was the attention image T, other A configuration is adopted in which the reduced image sequence 41 is displayed on the display screen by enlarging the image.

  According to the display control method according to the above-described embodiment, it is possible to realize a display control mode capable of searching for interesting content with a simple operation.

  On the other hand, a still image, a moving image related to the still image, a reduced image sequence 41 in which a plurality of reduced images of the still image are arranged in a strip shape, and a pointer 32 indicating the position on the display screen are displayed on the display screen. An image display step, a position detection step for detecting the position of the pointer 32, and a position detection step when the pointer 32 is positioned on any one of the images of interest T in the image of the reduced image sequence 41 A display control step of enlarging the attention image T from other images and displaying the reduced image sequence 41 on the display screen when detected, by selecting the attention image T; On the premise of a display control program to be realized by a computer having an image reproduction function capable of reproducing at least one of a still image and a moving image related to the still image In the control step, it is within the display area of the enlarged attention image T, and is outside the dead zone 73 that exists in the display area and maintains the enlargement of the attention image T regardless of the position of the pointer 32. When the position detection step detects that the pointer 32 is located, the image adjacent to the off-position side is regarded as the new attention image NT and replaced with the image that was the attention image T. Thus, a configuration in which the reduced image sequence 41 is displayed on the display screen in a larger size than the other images is adopted.

  According to the display control program according to the above-described embodiment, it is possible to realize a display control mode capable of searching for interesting content with a simple operation.

  In the display control program according to the embodiment, the dead zone 73 of the target image T may be configured based on the display region occupied by the reduced image corresponding to the target image T.

  With this configuration, each image can be sequentially enlarged and displayed while seamlessly straddling the adjacent images in the reduced image sequence 41. Therefore, it is possible to realize a display control mode excellent in intuitive operation in the sense that the pointer moves smoothly between adjacent adjacent images and does not cause a sense of incongruity.

  Further, the display control unit 37 may adopt a configuration in which the reduced image sequence 41 is displayed with a mountain shape as a whole by gradually reducing the enlargement with the attention image T as a vertex.

  With this configuration, the image T of the reduced image sequence 41 has a peak shape of the image of interest T, and a mountain-like shape in which the enlargement is gradually reduced, and is within a predetermined interval of the images on both sides of the image of interest T. Since the semi-enlarged images 77a and 77b existing in the range are enlarged and displayed from the fine image 43 having the fine image size, it is possible to improve the apparent graspability of the semi-enlarged images 77a and 77b. In particular, since the images 77a1 and 77b1 existing immediately on both sides of the target image T are enlarged and displayed in a sufficiently large size as compared with the reduced image 42 of the reduced image size, it is possible to remarkably improve the visibility at a glance. .

Finally, the display control program according to the above embodiment is recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, or a magnetic tape, or via a network such as the Internet. It is possible to increase the distribution by transmitting the data.
