Abstract
An indicia reading terminal can comprise an image sensor integrated circuit having a two-dimensional image sensor, a hand held housing encapsulating the two-dimensional image sensor, and an imaging lens configured to focus an image of a target decodable indicia onto the two-dimensional image sensor. The two-dimensional image sensor can include a plurality of pixels arranged in repetitive patterns. Each pattern can include at least one pixel sensitive in a first spectrum region, at least one pixel sensitive in a second spectrum region, and at least one pixel sensitive in a third spectrum region. The image sensor integrated circuit can be configured to capture a frame of image data by reading out a plurality of analog signals. Each read out analog signal can be representative of light incident on a group of two or more pixels of the plurality of pixels. The image sensor integrated circuit can be further configured to convert the plurality of analog signals to a plurality of digital signals and to store the plurality of digital signals in a memory. The indicia reading terminal can be operative to process the frame of image data for attempting to decode for decodable indicia.
