Claim 14:
15. The apparatus of claim 14, wherein the memory of each pixel cell of the array of pixel cells includes the shift register to store the pixel-level programming data;
wherein the peripheral circuit is configured to transmit the shift signal to the shift register of each pixel cell to:
at the first time, cause a first subset of the array of pixel cells to perform the first light measurement operation to generate a first frame, the first subset of the array of pixel cells corresponding to a region-of-interest (ROI) in the first frame; and
at the second time, cause a second subset of the array of pixel cells to perform the second light measurement operation to generate a second frame, the second subset of the array of pixel cells corresponding to the ROI in the second frame.
