Composite still-image creating device capable of creating a still image from moving images
First Claim
1. A composite still image creation device comprising:
- an acquisition unit for acquiring moving images coded using an interframe predictive coding process;
a select unit which, on the basis of motion vectors used in decoding each frame image contained in the moving images acquired by the acquisition unit, selects partial images in the frame image; and
a combining unit which combines the partial images selected by the select unit with a still image to create a composite still image.

Abstract
Each of the frames forming moving images is decoded in sequence and while a candidate frame is decoded, a decision is made as to whether or not the motion vector variable-length decoded for each macroblock is greater than a threshold, so that if the motion vector is greater than the threshold, the decoded image of the corresponding block is decided as a partial image forming a subject portion that had motion in the candidate frame and then combined with a base image stored in a still memory in a combining unit, whereby, by repeating this process, a composite still image which allows the motion of the subject to be grasped visually is created in the still memory.
