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.
