Motion-compensated hdr color image generation from single-shot sensor
A recently granted patent (Publication Number: US11922639B2) discloses a method for generating motion-compensated high-dynamic-range (HDR) color images using a dual-exposure-time single-shot HDR color image sensor. The method involves obtaining pixel values from sensor pixels, selecting colors based on luminance evaluation, determining motion parameters, and demosaicing to determine output values for each color. The process includes evaluating motion compensation necessity, using fit weights based on noise models, and calculating disparities between short and long exposure values to determine motion parameters. The method also involves selecting local regions for image generation at different resolutions and using a square section of sensor pixels for processing.
Furthermore, the patent includes a computer program product encoded with machine-readable instructions for implementing the method. The program includes data selection, motion, and demosaicing instructions, along with fit weight functions, parameter storage for region size and step size, and non-motion-compensated demosaicing instructions. The program also includes instructions for evaluating motion compensation necessity based on saturation criteria and disparity thresholds. Additionally, the patent covers a motion-compensated HDR camera equipped with the program stored in non-transitory memory and connected to a dual-exposure-time single-shot HDR color image sensor for capturing pixel values. The camera utilizes the method described in the patent to generate high-quality HDR color images with motion compensation capabilities.
