1. Video reproduction apparatus comprising:
- an imager including an array of photosites arranged in rows thereof;
means for reading out said array of photosites in blocks of photosites wherein a plurality of said blocks are each comprised of a respective plurality of photosite rows within each block to produce an output frame signal comprised of blocks of information in a serial format with each block of information being comprised of a plurality of parallel lines of video information that correspond to the photosite rows in each block;
means for selecting a number of said blocks of photosite rows of a frame signal for a readout as a partial frame wherein the total number of blocks in a frame signal divided by said selected number of blocks is an integer N;
means for producing successive pluralities of partial frames of information by reading out said selected number of blocks N times for each frame signal of said imager;
a video display;
control means for controlling said display to selectively operate in a first mode wherein said N partial frames of a frame signal are displayed simultaneously on said display and in a second mode wherein said N partial frames of a frame signal are displayed sequentially on said display such that only one said partial frames is displayed on said video display at any time and each of said N partial frames are displayed consecutively.
