COLOR FILTER ARRAYS FOR IMAGE SENSORS

Methods, systems, apparatus, including computer-readable media storing executable instructions, for color filter arrays for image sensors. In some implementations, an imaging device includes a color filter array arranged to filter incident light. The color filter array has a repeating pattern of color filter elements. The color filter elements include yellow filter elements, green filter elements, and blue filter elements. The imaging device includes an image sensor having photosensitive regions corresponding to the color filter elements. The photosensitive regions are configured to respectively generate electrical signals indicative of intensity of the color-filtered light at the photosensitive regions. The imaging device includes one or more processors configured to generate color image data based on the electrical signals from the photosensitive regions.
