Abstract:
1. An imaging device, comprising: a sensor array of M×N pixels, wherein all available M×N pixels are used for imaging of a target during a passive mode, and a subset of the available M×N pixels is used for imaging during an active mode, wherein the subset of the available M×N pixels is less than all available M×N pixels; and a readout circuit operatively coupled to the M×N sensor array, wherein each pixel of the array is associated with an input cell of the readout circuit, and the input cells associated with the subset of the available M×N pixels are configured differently than the other available input cells, and wherein in the active mode, input cells not associated with the subset of the available M×N pixels can be powered down.
