Abstract
An image sensor device includes a plurality of color filter units arranged in an array, each of the color filter units comprising an array of n*m color filters, and n and m are integers equal to or greater than 3. The plurality of color filter units includes a plurality of first color filter units, a plurality of second color filter units, and a plurality of third color filter units. The color filters of the first color filter units are transmissive to light beams within a first wavelength range, the color filters of the second color filter units are transmissive to light beams within a second wavelength range, and the color filters of the third color filter units are transmissive to light beams within a third wavelength range.
