摘要： There is provided a CMOS imager system for providing a viewable image having increased dynamic range including an image sensor including a number of sets of pixels. Each set of pixels is configured to receive one of a number of exposures and to generate image data corresponding to the received exposure in the interleaved mode. The image sensor is configured to operate in either an interleaved mode or a non-interleaved mode and to output the image data generated by each set of pixels as a frame of interleaved image data in the interleaved mode. The imager system further includes an interleaved image pipeline in communication with the image sensor, where the interleaved image pipeline is configured to receive the interleaved image data from the image sensor, combine the image data generated by each set of pixels corresponding to one of the exposures to form the viewable image.

摘要： A method for pixel color correction includes the steps of determining a gray degree of a designated pixel; generating an adjusted color correction matrix according to the gray degree of the designated pixel; and applying the adjusted color correction matrix to the designated pixel to correct color errors of the designated pixel. The gray degree is generated according to a ratio of the chrominance information to the luminance information. A weighted sum of a reference color correction matrix and a unity matrix is calculated to generate the adjusted color correction matrix, and weighting factors of the reference color correction matrix and the unity matrix are determined by the gray degree, wherein the unity matrix is a fundamental matrix without color correction.
