Abstract
A color camera includes at least three sub-cameras, each sub-camera having an imaging lens, a color filter, and an array of detectors, The color camera combines images from the three sub-cameras to form a composite multi-color image, wherein the three sub-cameras include a total number of detectors N and a total number of different color sets X, wherein a first number of signals of a first color set is less than N/X and a second number of signals of a second color set is greater than N/X, signals of the second color set being output from at least two of the three sub-cameras, wherein resolution of a composite image of the second color set is greater than resolution of an individual sub-camera and a resolution of the composite image. Corresponding images of the same color set may be shifted, either sequentially or simultaneously, relative to one another.
