Claim Text:
1. A method comprising: generating a temporal sequence of modulation patterns for an array of light modulating elements, wherein the temporal sequence of modulation patterns is based on a predefined measurement matrix, wherein said generating is performed by digital circuitry, wherein each of the modulation patterns is generated by performing a set of operations including: wherein the permutation is defined so that a first subset of the modulation patterns are coarse patterns that respect a partition of the array of light modulating elements into an array of superpixels, wherein each of the superpixels includes a respective group of the light modulating elements; modulating a light stream with the temporal sequence of modulation patterns to obtain a modulated light stream, wherein said modulating is performed by the array of light modulating elements; and acquiring measurements of intensity of the modulated light stream using a light sensing device, wherein each of the measurements corresponds to a respective one of the modulation patterns.
