Title: Dynamic image coder and its coding processing method
Inventor: YAMAUCHI TATSURO
IPC: H04N19/91
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in a coding frequency by preventing deterioration in motion vector detection accuracy due to a decoded dynamic image signal. SOLUTION: A frame memory 16 delays a dynamic image signal from an input terminal 30 by a single frame and gives the resulting signal to a motion vector detection circuit 18. The motion vector detection circuit 18 detects the motion vector from the dynamic image signal of a current frame from the input terminal 30 and dynamic image signal of a preceding frame that is directly delayed from the frame memory 16. A motion correction circuit 20 corrects the received dynamic image signal by the detected motion vector. An inter-frame coding circuit 22 obtains inter-frame coding between the dynamic image signal of the current frame the motion of which is corrected and the decoded dynamic image signal of the preceding frame by a decoding circuit 14.  A compositing circuit 26 provides an output of the coded signal with the coded motion vector as a prescribed coded bit stream to an output terminal 40.
