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.
