ABSTRACT:
In the moving image display device of the invention, a synthesis circuit inputs signals representing specified values of pixel rate factors R2and R3from a pixel rate factor specification circuit, while inputting overscanned frame image data D1in the units of pixels from a 1stlatch circuit. The synthesis circuit extracts a preset number of pixels corresponding to the specified value of the pixel rate factor R2from a prior frame image, while extracting a preset number of pixels corresponding to the specified value of the pixel rate factor R3from a latter frame image. The positions of pixels to be extracted from the latter frame image are complementary to the positions of pixels to be extracted from the prior frame image. The synthesis circuit combines the extracted pixels of the prior frame image with the extracted pixels of the latter frame image by a logical OR operation to generate intermediate frame image data D2. This technique of the invention is significantly simpler than the prior art technique but still effectively prevents flicker in a moving image to ensure smooth display of the moving image.
