Abstract

PURPOSE:To realize the color display of video information at least behind a second line by controlling the periodical readout of a memory at a memory readout control part in case of displaying the video information which constitutes one field of (n) lines consisting of a color burst part and a video signal part, respectively as a color still picture. CONSTITUTION:The readout of the first line and the second line of a picture memory 33 are performed by reading out a video part (c) following a color burst part (b). The readout of odd lines in a third line and after are performed by reading out the video part (c) of the first line following the color burst part (b) of the same line. The readout of even lines are performed by reading out the video part (c) of the second line following the color burst part (b) of the same line. The above stated readout control is performed periodically at the timing of a clock generation part 341, and when the video information to the second line is stored in the picture memory 33, preparation for color display is started, And at a time when the video information of the third line and after are stored in the picture memory 33 and the actual video information behind a readout access third line are read out, the color display is performed.
