DIGITAL CAMERAS WITH DIRECT LUMINANCE AND CHROMINANCE DETECTION

Abstract: a digital camera system and method for improving low-light performance. the system includes a plurality of digital cameras, each comprising a luminance channel configured to directly detect luminance signals, one or more chrominance channels configured to detect red and blue chrominance signals, and an optical assembly with lenses optimized for light transmission. a processor is configured to combine luminance and chrominance signals from the cameras to generate image data, independently adjust the integration times for each camera based on the image data to form optimized image data, and transmit the optimized image data for use in digital imaging systems, such as those in automobiles. the invention also encompasses a method and a non-transitory computer-readable medium for performing these operations, providing an efficient solution for capturing high-quality images in low-light environments.
