CMOS pixel aperture structure for extracting depth information

抄録

Complementary metal-oxide-semiconductor (CMOS) pixel aperture structure for extracting depth information is presented. The proposed structure uses RGBW pixel patterns and the aperture is located in the white pixel. The focused image is obtained by white pixels and the defocused image by RGB pixels. Both the focused image and the defocused image can be used to obtain depth information of the object.
