An imaging system of the invention includes an image array sensor including a plurality of pixels. Each of the pixels generates a signal indicative of the amount of light received on the pixel. The imaging system further includes an analog to digital converter for quantizing the signals from the pixels into a digital value. The system further includes a memory including a plurality of allocated storage locations for storing the digital values from the analog to digital converter. The number of allocated storage locations in the memory is less than the number of pixels in the image array sensor. According to another embodiment, an imaging device includes an image sensor having a plurality of pixels arranged in an array; and a multi-layer interference filter disposed over said pixel array, said multi-layer interference filter being patterned so as to provide filters of different colors to neighboring pixels or groups of pixels.
