1. A camera system, comprising: a substrate having a first side and a second side opposite to the first side; an array of image pixels disposed in or on the substrate, the array of image pixels laid out in a multi-ring pattern, wherein the array of image pixels are coupled to acquire image data of a color image in response to light incident on the array of image pixels; a color filter array (“CFA”) disposed over the first side of the substrate and positioned to color filter the light incident on the array of image pixels, the CFA including at least two different color filter types that filter different color bands of the light, wherein the CFA includes a plurality of color filter elements that optically subtend different portions of the array of image pixels at the same time and wherein each of the color filter elements optically subtends a plurality of the image pixels at a given time; an actuator coupled to the CFA to adjust the CFA in a sequence; and a controller coupled to the actuator to control the sequence such that each image pixel in the array of image pixels is temporarily optically subtended by each of the at least two different color filter types in the CFA while acquiring the image data associated with the color image.
