ABSTRACT:
The image signal processing apparatus for prompter provides a screen easy to view from which horizontal flickering on an image in horizontal scroll is eliminated. In a unit for displaying image data of a manuscript with interlace scanning, and horizontally scrolling the displayed manuscript in various speeds, a timing signal generator circuit generates clock signals with half a cycle shift, and a control circuit reads and processes even fields with clock signals with half a cycle shift at a scroll speed of, for example, a screen/six seconds, and reads and processes the last one of three continuous fields with the clock signals with half a cycle shift at a scroll speed of a screen/12 seconds. This enables it to continuously move pixels in the horizontal scroll.
