Title: PHASE DETECTION AUTOFOCUS USING OPPOSING FILTER MASKS
Abstract:
An example sensor for phase detection autofocus includes a number of photodiodes to capture light in a number of wavelengths. The example sensor also further includes a color filter array including a grid of alternating color pass filters corresponding to the number of photodiodes. The example sensor further includes a mask including a number of filters to separate a band of light by blocking the band of light on opposing portions of at least two of the alternating color pass filters.
