Abstract
An imaging sensor for low light level color imaging includes an array of pixels. Each pixel has a first pixel portion that has a first photosensitive area and is responsive to light in a panchromatic spectral range and a second pixel portion that has a second photosensitive area and is responsive to light in a sub-band spectral range. The first photosensitive area is greater than the second photosensitive area and the sub-band spectral range is narrower than and contained within the panchromatic spectral range. The first and second pixel portions of each pixel are independently addressable. The imaging sensor is beneficial for applications requiring wide dynamic range, low light sensitivity and color discrimination, and enables improved object discrimination and scene interpretation.
