VIDEO IMAGE ENCODING DEVICE AND VIDEO IMAGE ENCODING METHOD

摘要

A video image encoding device 100, in a first mode, variable-length-codes a residual coefficient to generate a coefficient code string, outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string, in a second mode, directly uses a differential image as a coefficient code string without variable-length-coding the differential image, and outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string.
