Abstract
Single substrate device is formed to have an image acquistition device and a controller. The controller on the substrate controls the system operation.
Claims2
A camera on a chip, comprising:
- a substrate, including an array of pixel areas, and at least one control area integrated on the same substrate;
- said pixel areas comprising a plurality of light collecting elements which each receive light and store an electronic information in an amount indicative of an amount of light received during an integration period;
- said control area including:
- a timing element;
- a readout control element,
- wherein circuitry in said control area are formed of CMOS, and said pixel area is formed of a logic family that is compatible with CMOS.

An imaging system on a single substrate, comprising:
- a substrate, including an array of pixel areas, and at least one control area integrated on the same substrate;
- said pixel areas comprising a plurality of light collecting elements which each receive light and store an electronic information in an amount indicative of an amount of light received during an integration period;
- said control area including:
- a timing element;
- wherein circuitry in said control area are formed of CMOS, and said pixel area is formed of a logic family that is compatible with CMOS;
- and
- a latch element, storing values to be used in said timing element.
