INFORMATION PROCESSING APPARATUS AND METHOD OF CONTROLLING SAME
First Claim
1. An information processing apparatus comprising:
- an input unit configured to input moving image data that includes a plurality of frame images arranged in a time series;
a detecting unit configured to detect a frame image, which includes an image similar to a prescribed image pattern, from moving image data that has been input;
a tracking unit configured to detect a frame image, which includes an image similar to the image included in the frame image detected by said detecting unit, detection being performed by adopting frame images before and after the detected frame image as a target;
a storage unit configured to store, as an image sequence, successive frame images that have been detected by said tracking unit, the successive images being stored in association with time information in the moving image data corresponding to the image sequence;
a splitting unit configured to split the moving image data into a plurality of time intervals based upon whether one or more image sequences have been stored in said storage unit at each time in the moving image data; and
an extracting unit configured to extract, from each of the plurality of time intervals, a representative frame image using different evaluation rules depending upon whether the interval includes one or more image sequences which have been stored in said storage unit at each time in the moving image data.

Abstract
An information processing apparatus for extracting a more appropriate representative frame image from moving image data that includes a plurality of frames of image data arranged in a time series includes: an input unit configured to input moving image data; a detecting unit configured to detect a frame image, which includes an image similar to a prescribed image pattern; a tracking unit configured to detect a frame image, which includes an image similar to the image included in the detected frame image; a storage unit configured to store successive frame images that have been detected by the tracking unit; a splitting unit configured to split the moving image data into a plurality of time intervals; and an extracting unit configured to extract a representative frame image using different evaluation rules.

5. A method of controlling an information processing apparatus for extracting one or more representative frame images from moving image data that includes a plurality of frame images arranged in a time series, said method comprising:
-
an input step of inputting moving image data; a detecting step of detecting a frame image, which includes an image similar to a prescribed image pattern, from moving image data that has been input; a tracking step of detecting a frame image, which includes an image similar to the image included in the frame image detected at said detecting step, detection being performed adopting frame images before and after the detected frame image as a target; a storage step of storing, as an image sequence, successive frame images that have been detected at said tracking step, the successive images being stored in a storage unit in association with time information in the moving image data corresponding to the image sequence; a splitting step of splitting the moving image data into a plurality of time intervals based upon whether one or more image sequences have been stored in the storage unit at each time in the moving image data; and an extracting step of extracting, from each of the plurality of time intervals, a representative frame image using different evaluation rules depending upon whether the interval includes one or more image sequences which have been stored in the storage unit at each time in the moving image data.
