Abstract: Example embodiments provide a color filter pattern for a plenoptic sensor. In some embodiments, the plenoptic sensor is a nona-pixel sensor comprising a plurality of microlenses and a respective 3×3 array of color filter pixels under each microlens. The filter pixels have three different colors, and the colors of the color filter pixels are arranged such that each of the sub-aperture images generated from the plenoptic image has an extended Bayer pattern, and such that the pixels of a refocused image generated by adding the sub-aperture images with a disparity value of zero or one receive contributions from three pixels of the first color, three pixels of the second color, and three pixels of the third color.

Abstract: Some embodiments of an apparatus, for example a light-field apparatus, may include a microlens; a color filter system; and two or more plenoptic subpixel sensors, the two or more plenoptic subpixel sensors comprising two or more photodiodes formed in a silicon layer, wherein a pyramid shape is etched in the two or more respective silicon photodiodes formed in the silicon layer.
