Abstract
A thumbnail display screen is displayed. The thumbnail display screen contains a first thumbnail array and a second thumbnail array, in which the images of two groups of frames extracted from a moving image file according to different rules are aligned in the order of appearance in the moving image. The first thumbnail array can be shifted forward or backward via an input apparatus, and the second thumbnail array is shifted in conjunction with a shift of the first thumbnail array. When one of the frames on the thumbnail display screen is selected, the moving image is played from the selected frame or the nearest scene switching point from the frame.
Claims13
An information processor comprising:
- a central processing unit for controlling a frame extraction unit which extracts a plurality of frame sequences, each of the frame sequences being extracted from an identical moving image at different time intervals on a time axis of the moving image;
- a decoding unit which decodes data of the plurality of frame sequences extracted by the frame extraction unit;
- a display unit having a display screen which simultaneously displays a plurality of thumbnail arrays of decoded images, and
- an input unit which accepts a user's instruction for selecting a thumbnail array, from among a plurality of thumbnail arrays simultaneously displayed by the display unit, as a target to be shifted, forward or backward,
- wherein each thumbnail array corresponds to a particular one of the plurality of frame sequences, and each thumbnail in a thumbnail array represents one of the frame sequences in the corresponding particular one of the plurality of frame sequences,
- wherein the plurality of thumbnail arrays are displayed in the order of appearance in the moving image so that all of the displayed plurality of the thumbnail arrays include a thumbnail from each thumbnail array that represents a frame sequence that includes the same time on the time axis of the moving image,
- wherein the frame extraction unit identifies, in accordance with the user's instruction, a frame to be displayed in the selected thumbnail array after the shifting and further extracts frame data to be newly displayed;
- and
- wherein the display unit updates the selected thumbnail array with a frame identified by the frame extraction unit.

An information processing method, comprising:
- extracting at plurality of frame sequences, each of the frame sequences being extracted from an identical moving image at different time intervals on a time axis of the moving image;
- decoding extracted data of the plurality of frame sequences to generate image data and storing the image data in a buffer;
- reading image data stored in the buffer and simultaneously displaying on a display a plurality of thumbnail arrays of decoded images;
- accepting a user's instruction for selecting a thumbnail array, from among a plurality of thumbnail arrays simultaneously displayed, as a target to be shifted, forward or backward;
- identifying, in accordance with the user's instruction, a frame to be displayed in the selected thumbnail array after the shifting and further extracting frame data to be newly displayed;
- and
- updating the selected thumbnail array with the identified frame,
- wherein each thumbnail array corresponds to a particular one of the plurality of frame sequences, and each thumbnail in a thumbnail array represents one of the frame sequences in the corresponding particular one of the plurality of frame sequences, and
- wherein the plurality of thumbnail arrays are displayed in the order of appearance in the moving image so that all of the displayed plurality of the thumbnail arrays include a thumbnail from each thumbnail array that represents a frame sequence that includes the same time on the time axis of the moving image.

A non-transitory computer readable medium encoded with a computer program that when executed on a processor causes the computer to perform a information processing method, comprising:
- extracting a plurality of frame sequences, each of the frame sequences being extracted from an identical moving image at different time intervals on a time axis of the moving image;
- decoding extracted data of the plurality of frame sequences to generate image data and Storing the image data in a buffer;
- reading image data stored in the buffer and simultaneously displaying on a display a plurality of thumbnail arrays of decoded images;
- accepting a user's instruction for selecting a thumbnail array, from among a plurality of thumbnail arrays simultaneously displayed, as a target to be shifted, forward or backward;
- identifying, in accordance with the user's instruction, a frame to be displayed in the selected thumbnail array after the shifting and further extracting frame data to be newly displayed;
- and
- updating the selected thumbnail array with the identified frame,
- wherein each thumbnail array corresponds to a particular one of the plurality of frame sequences, and each thumbnail in a thumbnail array represents one of the frame sequences in the corresponding particular one of the plurality of frame sequences, and
- wherein the plurality of thumbnail arrays are displayed in the order of appearance in the moving image so that all of the displayed plurality of the thumbnail arrays include a thumbnail from each thumbnail array that represents a frame sequence that includes the same time on the time axis of the moving image.
