A portable display apparatus selectively operable in a still picture mode or a movie mode includes an operating section for allowing the user of the device to select either one of the two modes. In the movie mode, a synchronous movie processing section relates color data fed and color data to be output on an integral multiple basis and thereby synchronizes input color data and output color data. Void pixels where color data are absent are interpolated to generate a plurality of lines. Consequently, three colors R(red), G (green) and B (blue) are output at the same time in synchronism with a vertical timing as well. Therefore, the generated lines can adequately display a picture alone. Not all the color data are stored or processed, as customary with conventional two field memories, but only necessary lines are used for display. In the still picture mode, the color data fed are temporarily stored. A color data interpolating section executes interpolation with the stored color data to thereby generate a high quality still picture. This makes the most of resolution available with a display and displays a high resolution picture. The display apparatus can therefore fully use power available for a synchronous movie, operates over a long period of time when a portable apparatus including the display apparatus is carried by the user, and thereby noticeably improves the function of the apparatus.
