20090290052 | Color Pixel Pattern Scheme for High Dynamic Range Optical Sensor - The use of a Bayer pattern array in digital image sensors to enhance the dynamic range of the sensors is disclosed. Each Bayer pattern in the array can include three different pixels having a first exposure, and a fourth pixel (which is the same color as one of the other pixels in the array) having a second exposure. The dynamic range of the Bayer pattern array can be enhanced by using different exposure times for the pixels. Each pixel can capture only one channel (i.e. either red (R), green (G) or blue (B) light). Interpolation of neighboring pixels, including those having different exposure times, can enable the pixels in the Bayer pattern array to generate missing color information and effectively become a color pixel, and can allow the Bayer pattern array to have a higher dynamic range. | 11-26-2009 |
