Abstract
An optical detection system can include a set of photodetectors and a set of pixel processing circuits for processing pixel information provided by the set of photodetectors. A set of switches interposed between the set of photodetectors and the set of pixel processing circuits can be selectively activated to place the optical detection system in a first mode of operation that allows for optical detection using a subset of pixel processing circuits. The remaining pixel processing circuits that are not used during the first mode of operation can be placed in a power down condition for conserving power. The set of switches can then be re-activated as needed, to place the optical detection system in a second mode of operation that allows for optical detection using a larger number of pixel processing circuits than used during the first mode of operation.
