Abstract
A control system for controlling an image array sensor and controlling communication between the image array sensor and a microcontroller by way of a serial communication interface. The control system is able to efficiently control various aspects of the image array sensor such as windowing, mode of operation, sensitivity as well as other parameters in order to reduce the data throughput. An important aspect of the invention relates to the fact that the control circuit can be rather easily and efficiently configured in CMOS with rerlatively few output pins which enables the control circuit to be rather easily and efficiently intergrated with CMOS based image array sensors and even the microcontroller to reduce the part count and thus, the overall cost of the system.
