Abstract
A reproduction control apparatus that enables a user to perform fast forward and fast rewind of a moving image by an intuitive operation, and provides good operability. The reproduction apparatus controls reproduction of a moving image including a plurality of frames. A controller detects selection of an area including an object by a user's touch operation during reproduction of the moving image. The size of an object is detected for each of the plurality of frames. The controller searches for a frame including the object, which corresponds in size to the size of the selected area, and the frame found by the search is reproduced and displayed.
Claims10
A reproduction control apparatus that controls reproduction of a moving image including a plurality of frames, comprising:
- a storage device;
- and
- a processor configured to execute computer executable instructions recorded on the storage device, the computer executable instructions including instructions, that when executed by the processor, cause the reproduction control apparatus to:
- reproduce a first frame among the plurality of frames of the moving image;
- render an object frame which identifies an object according to both a position and a size of the object which is included in the first frame of the moving image, during the reproduction of the first frame of the moving image;
- detect selection of the object frame, of the first frame of the moving image, including the object during reproduction of the first frame of the moving image;
- detect a change in size of the selected object frame, in response to a user's operation;
- search for a second frame among the plurality of frames of the moving image, including the object corresponding in size to the changed size of the selected object frame;
- and
- reproduce the second frame including the object corresponding in size to the changed size of the selected object frame in response to the detection of the change in size of the selected object frame, the first frame having a first reproduction time and the second frame having a second reproduction time different from the first reproduction time.
A method of controlling reproduction of a moving image including a plurality of frames, comprising:
- reproducing a first frame among the plurality of frames of the moving image;
- rendering an object frame which identifies an object according to both a position and a size of the object which is included in the first frame of the moving image, during the reproduction of the first frame of the moving image;
- detecting selection of the object frame, of the first frame of the moving image, including the object during reproduction of the first frame of the moving image;
- detecting a change in size of the selected object frame, in response to a user's operation;
- searching for a second frame among the plurality of frames of the moving image, including the object corresponding in size to the changed size of the selected object frame;
- and
- reproducing the second frame including the object corresponding in size to the changed size of the selected object frame in response to the detection of the change in size of the selected object frame, the first frame having a first reproduction time and the second frame having a second reproduction time different from the first reproduction time.
A non-transitory computer-readable storage medium storing a computer-executable control program for causing a computer to execute a method of controlling reproduction of a moving image including a plurality of frames,
- wherein the method comprises:
- reproducing a first frame among the plurality of frames of the moving image;
- rendering an object frame which identifies an object according to both a position and a size of the object which is included in the first frame of the moving image, during the reproduction of the first frame of the moving image;
- detecting selection of the object frame, of the first frame of the moving image, including the object during reproduction of the first frame of the moving image;
- detecting a change in size of the selected object frame, in response to a user's operation;
- searching for a second frame among the plurality of frames of the moving image, including the object corresponding in size to the changed size of the selected object frame;
- and
- reproducing the second frame including the object corresponding in size to the changed size of the selected object frame in response to the detection of the change in size of the selected object frame, the first frame having a first reproduction time and the second frame having a second reproduction time different from the first reproduction time.
