  • Image sensing device
    Patent number: 10855959
    Abstract: An image sensing device includes a pixel array of a 4×4 pixel unit including first to fourth sub-pixel arrays of 2×2 pixels. The first and second sub-pixel arrays are arranged in a first diagonal direction, and the third and fourth sub-pixel arrays are arranged in a second diagonal direction intersecting the first diagonal direction. The first and second sub-pixel arrays have a first color pattern, and the third and fourth sub-pixel arrays have second and third color patterns, respectively, and each of the first to third color patterns includes two or more colors.
    Type: Grant

  • Color filter array, image sensor including the same, and infrared data acquisition method using the same
    Patent number: 9535197
    Abstract: A color filter array includes first pixels, second pixels, third pixels, and fourth pixels. The first pixels transmit light with visible and infrared (IR) wavelengths. The second pixels transmit light with the visible wavelengths and surround each of the first pixels. The third pixels transmit light with a first range of wavelengths among the visible wavelengths. The fourth pixels transmit light with a second range of wavelengths among the visible wavelengths.
