ABSTRACT:
The invention concerns a device for reading quantities of electrical charge supplied by photodiodes. These photodiodes (1) are arranged at the intersections of rows and columns (4,5) of a matrix (area) array. The device consists of means (6) for storing charges coming from a row of column of the array during scanning, a shift register (10) having an input stage and n-1 intermediate stages, means (18, 20) for injecting bias charges into the receiving potential wells, and skimming type transfer means (19) for transferring the stored charges and bias charges towards the shift register. The readout during scanning of the charges form a row or column of photodiodes is obtained after n charge transfers and n-1 shift operations. With known devices, n readouts are carried out per row or column, making them very slow and/or inefficient with large or high-signal photodiodes.
