A device for acquiring color images using a color filter array. The color filter array includes a pattern of red array elements, green array elements, and blue array elements. The red array elements and green array elements occur in the color filter array more frequently than the blue array elements. This multiplicity of red, green, and blue color filters adheres closely to known human visual system (HVS) chrominance and luminance responses. Also, the pattern has periodicity in the diagonal directions and is relatively immune to Moire artifacts that arise due to interference between periodic sampling patterns of the CFA and periodic features in imaged scenes.
