Title: Moving compensation coding method
Inventor: AONO HIROAKI
IPC: H04N9/77
Filed: 1990-11-27
Abstract: PURPOSE:To attain movement compensation processing without increasing a code quantity by using the LSB of a color difference signal of each picture element so as to code moving information in the unit of blocks. CONSTITUTION:A luminance signal inputted from a luminance signal input terminal 1 is inputted to a frame memory 3 and a luminance signal of a preceding frame subjected to one frame delay is generated. A moving information detection circuit 4 compares a luminance signal of a preceding frame with a luminance signal of a current frame to detect moving information representing in which direction and how the signal is moved between the preceding frame and the current frame. The moving information divides one pattern into blocks of m-lines X n-picture elements each and the signal is detected in the unit of blocks from the frame correlation with respect to the preceding frame for each block. When the moving information is detected by the circuit 4, a switch 5 is used to set a least significant bit(LSB) of a color difference signal of a head picture element of a block from which the moving information is detected to logical 1 thereby coding the moving information to the LSB of color difference signals of the other picture elements. Thus, moving compensation processing is attained without increasing code quantity.
