Abstract
Effects of light intensity on disparity for depth extraction in monochrome CMOS image sensor with offset pixel apertures are investigated. The technology consumes less power, since it does not use external light sources. The offset pixel apertures are integrated in each pixel of the monochrome CMOS image sensor to acquire the disparity for depth extraction. Because the monochrome CMOS image sensor does not contain color filters, the height of the pixel is lower than that of the CMOS image sensor with color filters, resulting in a better disparity. The monochrome CMOS image sensor with offset pixel apertures was designed and fabricated using 0.11 μm CMOS image sensor process. Disparity of the sensor has been measured under various light intensities. The sensor might be useful for three-dimensional imaging in outdoor applications with a simple structure.
