Claim Text:
1. A demodulation sensor implemented on a chip, comprising: a pixel array comprising pixels each of which produces at least two samples of a scene, which is illuminated by modulated light from a light emitter; a proxel array on the chip, the proxel array being physically separated from the pixel array and comprising storage elements and processing elements, each of the storage elements operable to receive the at least two samples from a corresponding one of the pixels; and a transfer system to transfer the samples from the pixel array to the corresponding storage elements of the proxel array; wherein the proxel array is arranged to alternate storage of the at least two samples between two different storage elements to perform in-pixel mismatch cancellation, and wherein each storage element is arranged to accumulate a plurality of phase-delay-matching sub-images for a single image.
