Abstract
An image sensor includes a pixel array having a plurality of pixels. A readout circuit is coupled to the pixel array. A controller circuit is coupled to control the pixel array and is coupled to the readout circuit to receive array data from the pixel array. The controller circuit includes a mode control logic unit providing logic which when executed causes the image sensor operate in an idle mode of operation and then sample in response to receiving an event signal array data received from the pixel array in a pulsed mode of operation. A pattern in the array data samples over time is recognized and a mode of operation is selected in response to the recognized pattern.
