Claim One:
1. A control system for controlling the exposure to incident optical radiation of an active pixel image sensing device having a plurality of image signal generating pixels arranged in horizontal rows and vertical columns to form of a two-dimensional matrix, each row and column, respectively, having a respective row and column address, wherein the pixels in each horizontal row are connected to a first common horizontal reset line and a second common horizontal select line and the pixels in each vertical column are connected to a common vertical signal line, the control system comprising: vertical addressing means connected to each of said horizontal reset lines for resetting image signals of the pixels of a row connected to a predetermined one of said horizontal reset lines; said vertical addressing means also connected to each of said horizontal select lines for also selecting a predetermined one of said horizontal select lines for enabling image signals from pixels in the row connected to said selected select line to be read out; horizontal addressing means connected to each of said vertical signal lines for selecting a predetermined one of said vertical signal lines and for reading out the signal of the pixel simultaneously selected through said horizontal select lines and said vertical signal lines; control means connected to said horizontal and vertical addressing means for controlling said horizontal and vertical addressing means so that said vertical addressing means selects a first one of said horizontal reset lines to reset the image signals of the pixels of that row connected to said first one of said horizontal reset lines, and thereafter selects a second one of said horizontal select lines to enable the image signals of the pixels of that row connected to said second one of said horizontal select lines to be read out, wherein said second one of said horizontal select lines is spaced apart from said first one of said horizontal reset lines by a predetermined number of horizontal select lines, and said horizontal addressing means simultaneously selects in ordered sequence predetermined ones of said vertical signal lines to read out in said ordered sequence the image signals from the pixels of that row connected to said second one of said horizontal select lines, said control means thereafter operating to control said vertical addressing means to alternately select succeeding predetermined ones of said horizontal reset and select lines and to control said horizontal addressing means to simultaneously select predetermined ones of said vertical signal lines in said ordered sequence to read out the image signals from the pixels of the succeeding rows connected to the selected horizontal select lines.
