extracting the frame including the object image from the video content; and

generating display data including a reduced image corresponding to the frame for display and additional information indicating the number of times the object image is included in the frame.

12. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

receiving, at a user interface of the information processing apparatus, a selection corresponding to the object image.

13. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

detecting the object image corresponding to the object identification information from the frame when the video content is reproduced.

14. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

generating and displaying a progress bar indicating a total playback time and a playback progress of the video content.

15. The non-transitory computer-readable recording medium according to claim 14 , further comprising:

populating the progress bar with a predetermined mark correlating the reduced image with the progress bar based on playback time information of the frame.

16. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

receiving a selection corresponding to the reduced image; and

moving a reproduction position of the video content to a reproduction position of the frame corresponding to the selected reduced image.

17. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

displaying an object detection window including a plurality of object images for selection;

receiving an input corresponding to one of the plurality of displayed object images;

extracting a frame from the plurality of frames including the selected object image; and

generating the display data including said reduced image from the extracted frame and indicating a number of times the selected object image is included in the frame.

18. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

extracting, of a plurality of frames including the object image, a single frame representative of the plurality of frames over a predetermined time period to generate the display data.

19. The non-transitory computer-readable recording medium according to claim 11 , further comprising:

extracting, of a plurality of frames including the object image, a frame at a time of a scene change occurring from the video content to generate the display data.
