1. An imaging system comprising: at least three optical structures; at least three imaging structures that are respectively assigned to the at least three optical structures and that each capture a single-colored image of a same scene or object, at least one of the three imaging structures includes a deviated position from another one of the three imaging structures to capture a shifted version of the single-colored image that is deviated with respect to a reference point in the same scene or object imaged in both a first direction and a second direction by a deviation, and the deviation is less than a distance of one pixel; and image processing circuitry configured to generate a color image from at least three single-colored images captured by the three imaging structures, wherein a resolution of the color image is higher than a resolution of each single-colored image.
