  • Patent number: 11929383
    Abstract: A pixelated image sensor capable of simultaneously supporting an EVS mode and an image-frame capture mode of operation. An individual pixel of the sensor comprises two distinct sets of subpixels involved in the two modes, respectively, and at least two corresponding, functionally different and independent electrical circuits. The metal interconnect structure of the image-sensor IC is implemented using a wiring topology in which spatial overlap between the wirings of the two electrical circuits is optimized (e.g., minimized) to reduce inter-circuit crosstalk when the two circuits are active at the same time. Such wiring topology may be beneficial, e.g., due to the resulting improvements in the image quality for both operating modes.
