Abstract
A moving picture coder has a first coding mode in which the entire picture is coded and a second coding mode in which a partial region of the picture is coded. Coding is so performed that the frame rate inside the partial region is higher than that outside the partial region. To perform such coding, the coder comprises a region selecting section (201) for selecting the partial region, a shape coding section (202) for coding is the shape of the partial region, a moving picture coding section (204) for coding only the values of the pixels inside the partial region according to the selected region, and a coding control section (205). A moving picture decoder decodes a picture in the second mode by superimposing decoded picture data of the partial region of the picture in the second mode on the decoded picture data of the entire picture in the first mode.
