Abstract
When identification information of an appending start frame coincides with identification information of the final frame of moving image data of an existing moving image file, an image processing apparatus changes the appending start frame to another frame.
Claims18
An image processing apparatus comprising:
- a compression unit configured to compress moving image data and assign identification information to each frame of the compressed moving image data;
- a recording unit configured to record the moving image data compressed by the compression unit on a recording medium according to a recording instruction,
- the recording unit appending the compressed moving image data to a moving image file which has been already recorded on the recording medium;
- and
- a controller configured to determine a frame other than a specific frame of the moving image data compressed by the compression unit predetermined number of frames before the input timing of the recording instruction as an appending start frame and control the recording unit in such a way as to append the compressed moving image data of the appending start frame to the moving image file, if identification information of the specific frame coincides with identification information of a final frame of moving image data stored in the moving image file, and to determine the specific frame as the appending start frame and control the recording unit in such a way as to append the compressed moving image data of the appending start frame to the moving image file, if the identification information of the specific frame does not coincide with the identification information of the final frame of the moving image data stored in the moving image file.

An image processing apparatus comprising:
- a processing unit configured to output compressed moving image data, wherein identification information is assigned to each frame of the compressed moving image data;
- a memory configured to be capable of storing at least predetermined number of frames of the compressed moving image data, wherein the processing unit successively writes the compressed moving image data into the memory;
- a recording unit configured to record the compressed moving image data stored in the memory on a recording medium according to a recording instruction, the recording unit appending the compressed moving image data to a moving image file which has been already recorded on the recording medium;
- a control unit configured to determine an appending start frame for appending the compressed moving image data to the moving image file and control the recording unit to append the compressed moving image data of the appending start frame to the moving image file,
- wherein the control unit determines as the appending start frame a predetermined frame, of the compressed moving image data stored in the memory, the predetermined number of frames before the recording instruction if the identification information of a last frame of compressed moving image data stored in the moving image file does not coincides with the identification information of the predetermined frame, and determines as the appending start frame a frame other than the predetermined frame if the identification information of the last frame coincides with the identification information of the predetermined frame.

- and
- determining the specific frame as the appending start frame and appending the compressed moving image data of the appending start frame to the moving image file which has been already recorded on the recording medium, if the identification information of the specific frame does not coincide with the identification information of the final frame of the moving image data stored in the moving image file.
