    Abstract: Color filters may affect imaging performance attributes such as low light sensitivity, color accuracy, and modulation transfer function (MTF). In an image pixel array, these factors are influenced by both the spectral absorption and pattern of the color filter elements. Different portions of an image sensor may prioritize different imaging performance attributes. Accordingly, in certain applications it may be beneficial for color filter characteristics to vary across an image sensor. Different color filters of the same color may have different structures to optimize imaging performance across the image sensor.
