  • CMOS imager system with interleaved readout for providing an image with increased dynamic range
    Patent number: 8059174
    Abstract: 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.
