1. A method useful in determining information of an image, comprising: accumulating a first pixel signal based on incoming light energy for each of a plurality of pixel elements of a pixel array, the pixel elements each including a light sensor, the first pixel signals indicative of an image of a scene; and obtaining information of a measurement indicative of the image of the scene by: applying sets of control signals to rows of the pixel elements, pixel elements of each row sharing common control signals, each of the sets of control signals being substantially uncorrelated with each other, each of the sets of control signals being representative of a different vector of a matrix comprising a product of a random basis function and a filtering function having a frequency response tuned to desired spatial frequencies of interest in an expected image signal, for each set of control signals, aggregating, in accordance with the control signals, output signals based on the first pixel signals for columns of pixel elements, and digitizing each of the aggregated output signals of the columns of the pixel elements.
