Abstract

Apparatus for identifying one or more still images in one or more moving image contents. An identifying unit is configured to identify one or more still images included in the moving image contents having one or more features that closely resemble particular features. A display controller is configured to cause the display on a timeline associated with the moving image contents of the location of an identified still image in at least one of the moving image contents.

Claims

1. Apparatus for displaying moving images of different moving image contents, the moving images containing one or more still images having image features that match selected image features, said apparatus comprising:

an identifying unit configured to identify at least one particular still image included in different moving image contents, the identified still image having one or more image features that closely resemble one or more of the selected image features; and

a display information generator configured to generate information to cause a display, on timelines associated with the different moving image contents, of marker symbols representing the locations of the identified still image in different ones of said moving image contents, the marker symbols on the timelines associated with the different moving image contents being displayed in alignment with each other on a common axis of the timelines;

the display information generator being further configured to generate information to cause plural different moving images, as represented by the different moving image contents, to be reproduced and displayed concurrently as plural different moving images of the different moving image contents.

2. The apparatus of claim 1, wherein said identifying unit compares said one or more selected image features to corresponding features of still images in said different moving image contents.

3. The apparatus of claim 1, wherein said identifying unit identifies scenes in each of said different moving image contents that contain a still image whose features closely resemble said one or more selected features;

and

wherein said display information generator generates information to cause the display of said identified scenes.

4. The apparatus of claim 1, wherein said different moving image contents include audio information associated with said different moving image contents, and wherein said display information generator generates information to cause the display of timelines of signal waveforms of said audio information in respective ones of said different moving image contents.

5. The apparatus of claim 3, wherein said display information generator generates information to cause the display of indicia associated with respective ones of said different moving image contents representing durations and/or colors of the scenes in said respective moving image contents.

6. The apparatus of claim of claim 1, wherein said display information generator generates information to cause the display, along said timelines, of moving sliders representing current reproduction positions of the different moving image contents.

7. The apparatus of claim 1, wherein said identifying unit identifies scenes in each of said different moving image contents that contain a still image whose features closely resemble said one or more selected image features.

8. A method for displaying moving images of different moving image contents, the moving images containing one or more still images having image features that match selected image features, said method comprising:

identifying at least one particular still image included in different moving image contents, the identified still image having one or more image features that closely resemble one or more of the selected image features;

causing a display on timelines associated with the different moving image contents of marker symbols representing the locations of the identified still image in different ones of said moving image contents, the marker symbols on the timelines associated with the different moving image contents being displayed in alignment on a common axis of the timelines; and

causing plural different moving images, as represented by the different moving image contents, to be reproduced and displayed concurrently as plural different moving images of the different moving image contents.

9. The method of claim 8, wherein said one or more still images are identified by comparing said one or more selected features to corresponding features of still images in said different moving image contents.

10. The method of claim 8, wherein scenes in each of said different moving image contents that contain a still image whose features closely resemble said one or more selected features are identified;

and wherein said identified scenes are displayed.

11. The method of claim 8, wherein said different moving image contents include audio information associated with said different moving image contents, and further comprising displaying timelines of signal waveforms of said audio information in respective ones of said different moving image contents.

12. The method of claim 10, further displaying indicia associated with respective ones of said different moving image contents representing durations and/or colors of the scenes in said respective moving image contents.

13. The method of claim of claim 8, further comprising displaying moving sliders along said timelines, said moving sliders representing current reproduction positions of the different moving image contents.

14. A non-transitory computer-readable medium encoded with instructions that, when read by a computer, executes the method for displaying moving images of different moving image contents, the moving images containing one or more still images having image features that match selected image features, comprising:

identifying at least one particular still image included in different moving image contents, the identified still image having one or more image features that closely resemble one or more of the selected image features;

causing a display on timelines associated with the different moving image contents of marker symbols representing the locations of the identified still image in different ones of said moving image contents, the marker symbols on the timelines associated with the different moving image contents being displayed in alignment on a common axis of the timelines; and

causing plural different moving images, as represented by the different moving image contents, to be reproduced and displayed concurrently as plural different moving images of the different moving image contents.

15. Apparatus for identifying one or more still images in plural different image contents representing different moving images, said apparatus comprising:

an image input unit configured to receive an input search image;

an identifying unit configured to identify at least one still image included in said plural different moving image contents that match the inputted search image by comparing the inputted search image to the still images in the plural different moving image contents; and

a display information generator configured to generate information to cause a display, on timelines associated with the different moving images, of marker symbols representing the locations in the plural different moving image contents of a still image that matches the inputted search image, the marker symbols representing the locations of the still image in respective ones of the plural different moving image contents that matches the inputted search image being displayed on the timelines associated with the plural different moving image contents and in alignment on a common axis of the timelines.
