The synthesizing circuit inputs signals representing the brightness coefficient K2 and the brightness coefficient K3 from the multiplexer, and inputs the overscanned frame image data D1 in pixel units from the first latch circuit. When the start frame image read the third time and the after frame image read the first time are input simultaneously, the synthesizing circuit calculates the brightness coefficient K2 for the brightness value of the pixels of the start frame image, and calculates the brightness coefficient K3 for the brightness value of the pixel of the after frame image. Then, it synthesizes the pixels of the start frame image and the pixels of the after frame image for which the respective brightness coefficients were calculated, and generates the intermediate frame image data D2.
