Abstract
A single integrated circuit having an image sensor for outputting signals representative of input light; a programmable non-volatile memory for storing security information; a controller unit for interfacing with the programmable non-volatile memory and accessing the security information; and an input/output port for communicating with a control and post-processing circuit.
Claims20
A single integrated circuit comprising:
- an image sensor for outputting signals representative of input light;
- a programmable non-volatile memory for storing a plurality of identification information for use with different applications having different identification information requirements, and the sensor is adapted to be used in the different applications without updating the identification information;
- a controller unit for interfacing with said programmable non-volatile memory and accessing said identification information said controller unit containing circuits to sign output received from said image sensor using said identification information;
- and,
- an input/output port for communicating with a control and post-processing circuit.
