To provide a moving picture coding apparatus and TV phone wherein a handwritten image is coded with less quantity of calculation and less power consumption. The moving picture signal from camera is combined with handwritten image signal from pen input by combining circuit. Then, combined image as well as coding region information to discriminate a region to be coded is fed to motion compensative moving picture coding circuit. Motion compensative moving picture coding circuit deems that the region needless to be coded is the same as the latest frame. According to the present invention, a quantity of calculation and power consumption of moving picture coding apparatus and TV phone using the same can be reduced, by coding only the newly inputted handwritten image. Degradation of image quality can be reduced by putting its motion vector "0".
