Abstract
An image processing apparatus includes a moving image file storage unit operable to store a moving image file; an area selection receiving unit operable to receive a selection of a predetermined area corresponding to one of a plurality of frames forming the moving image file; a template image generating unit operable to generate as a template image an image of the selected area; an image matching unit operable to obtain the frames from the moving image file storage unit, and to match each of the frames against the template image to search for a matching frame containing an image similar to the template image; and a scene change detecting unit operable to detect a start and an end of a scene containing the matching frame.
Claims13
An image processing apparatus, comprising:
- moving image file storage means for storing a moving image file;
- area selection receiving means for receiving a selection of a predetermined area corresponding to one of a plurality of frames forming the moving image file;
- template image generating means for generating as a template image an image of the selected area;
- image matching means for obtaining the frames from the moving image file storage means, and for matching each of the frames against the template image to search for a matching frame containing an image similar to the template image;
- and
- scene change detecting means for detecting a start and an end of a particular scene containing the matching frame when the matching frame is matched, wherein the scene change detecting means analyzes a difference sum between at least one pair of the frames located prior to the matching frame in time to detect the start of the particular scene and analyzes a difference sum between at least one pair of the frames located subsequent to the matching frame in time to detect the end of the particular scene.
A processing method of an image processing apparatus including moving image file storage means storing a moving image file, the processing method comprising:
- receiving a selection of a predetermined area corresponding to one of a plurality of frames forming the moving image file;
- generating as a template image an image of the selected area;
- obtaining the frames from the moving image file storage means, and matching each of the frames against the template image to search for a matching frame containing an image similar to the template image;
- and
- detecting a start and an end of a scene containing the matching frame when the matching frame is matched, the detecting including analyzing a difference sum between at least one pair of the frames located prior to the matching frame in time to detect the start of the scene and analyzing a difference sum between at least one pair of the frames located subsequent to the matching frame in time to detect the end of the scene.
A non-transitory recording medium recorded with a program for causing an image processing apparatus to execute an image processing method, the image processing apparatus including moving image file storage means storing a moving image file, the method comprising:
- receiving a selection of a predetermined area corresponding to one of a plurality of frames forming the moving image file;
- generating as a template image an image of the selected area;
- obtaining the frames from the moving image file storage means, and matching each of the frames against the template image to search for a matching frame containing an image similar to the template image;
- and
- detecting a start and an end of a scene containing the matching frame when the matching frame is matched, the detecting including analyzing a difference sum between at least one pair of the frames located prior to the matching frame in time to detect the start of the scene and analyzing a difference sum between at least one pair of the frames located subsequent to the matching frame in time to detect the end of the scene.
An image processing apparatus, comprising:
- a moving image file storage unit operable to store a moving image file;
- an area selection receiving unit operable to receive a selection of a predetermined area corresponding to one of a plurality of frames forming the moving image file;
- a template image generating unit operable to generate as a template image an image of the selected area;
- an image matching unit operable to obtain the frames from the moving image file storage unit, and to match each of the frames against the template image to search for a matching frame containing an image similar to the template image;
- and
- a scene change detecting unit operable to detect a start and an end of a scene containing the matching frame when the matching frame is matched, wherein the scene change detecting unit analyzes a difference sum between at least one pair of the frames located prior to the matching frame in time to detect the start of the scene and analyzes a difference sum between at least one pair of the frames located subsequent to the matching frame in time to detect the end of the scene.
