Claim 1
Independent Claim
203 words
In a solid state electro-optical device, the combination of a mosaic sensor including a plurality of phototransistors onto which an optical image is to be focused, said transistors being arranged in a plurality of rows and orthogonal columns thus forming a matrix, the collectors of the phototransistors in the respective rows being connected to a first set of common conductors, the emitters of the phototransistors in the respective columns being connected to a second set of common conductors, a first set of collector switches equal in number to the number of rows connected between said first set of conductors and a first terminal, a second set of emitter switches equal in number to the number of columns connected between said second set of conductors and a second terminal, a load resistor connected between said first terminal and a third terminal, a source of direct current driving potential directly connected to said second and third terminals, means for sequentially closing said first set of switches, and means for sequentially closing said second set of switches at a rate higher than the closing rate of said first set to provide readout of saiD phototransistors in succession while commutating the emitters thereof to said second terminal.
