Abstract
An image processing system and method are provided which use a selectively ccessed detector array comprised of subarrays. Regions of image activity are located within the detection array through readout of the activity determining elements. Each subarray is evaluated to determine whether any image activity has been detected by the corresponding subarray. Data is only read for the active subarrays. Thus, the activity indicator allows efficient transfer of relevant data from the detector array without requiring previous information. This results in reduced data flow and generally shorter readout cycles. The activity determination can be a non-destructive process so that data contained in the detection array remains available for sensor readout. This eliminates the need to perform one detector exposure cycle to determine activity and a second cycle to read out data from the detector.
