Filed: 1989-10-31
Abstract: PURPOSE:To attain coding with less code quantity even to a luminance change caused due to change in a lighting condition by obtaining a moving vector minimizing an absolute sum or power of inter-frame difference except a DC component. CONSTITUTION:A variable delay device 151 applies position correction to a local decoding signal stored in a frame memory 140 in response to a moving vector detected by a moving vector detector 150 and a DC component correction device 152 corrects a DC component correction value detected by the moving vector detector 150 to generate an interframe prediction signal. The moving vector detector 150 eliminates a DC component from a prediction error signal with respect to each trial vector in the detection of a moving vector and compares absolute sums or powers to select a trial vector minimizing the values to be a moving vector and the DC component of the prediction error signal to the trial vector is a DC component correction value. Thus, the luminance change caused in the change of the lighting condition is coded with less coding quantity.
