The present invention provides a LUT circuit that can simultaneously determine the corresponding output values of a plurality of input values. The camera includes: a spectrum coded aperture including at least two regions that pass spectrum channels of an incident light field which are different from each other; and a sensor configured to record the at least two spectrum channels to form an image captured in a sensor basis. Then a second pattern of colored ink, of a different color than first pattern’s ink, is deposited upon the substrate on top of the first pattern, at 90-170 density.
