Abstract
A multiple resolution sensing apparatus comprises first and second arrays of photosensor elements and an image processing system. The first array exhibits a first signal-to-noise (S/N) ratio and a first input sampling rate (ISR). The first array also is operative to generate color information, corresponding to an image, that comprises at least one of red, green and blue information. The second array exhibits a second S/N ratio lower than the first S/N ratio and a second ISR higher than the first ISR. The second array is operative to generate luminance information corresponding to the image. The image processing system is communicatively coupled to the first array and the second array and is operative to receive the color information from the first array and the luminace information from the second array. The image procesing system also is operative to generate pixel data corresponding to the image, with the pixel data comprising the color information from the first array and the luminance information from the second array. Other apparatuses also are provided.
