Abstract
The present invention provides a spectral filter for an optical sensor. The spectral filter includes a substrate having a focus region and a defocus region, a panchromatic filter region disposed on the focus region of the substrate and a multi-spectral filter region disposed on the defocus region of the substrate. The panchromatic filter region includes a plurality of panchromatic pixels, while the multi-spectral filter region includes a plurality of multi-spectral pixels. Each of the multi-spectral pixels includes a plurality of color pixels.
