1. An image sensor, comprising:

  • a sensing layer for sensing a light beam; and

    a plurality of pixel groups, wherein each of the plurality of pixel groups corresponds to a pixel in an image captured by the image sensor, comprising;

    a yellow filter unit, which allows a green light component and a red light component of the light beam to pass through, wherein the yellow filter unit is a high-pass filter, allows at least 50% of the waves in the light beam with the wavelength longer than a specific wavelength to pass through, and the specific wavelength is defined as a 50% light transmittance wavelength within the range of 470nm to 540 nm;

    a green filter unit allowing the green light component of the light beam to pass therethrough, the green filter unit allowing a green light band of the light beam to pass therethrough, a short 50% transmittance wavelength of the green light band being equal to or shorter than the specific wavelength of the yellow filter unit; and

    a blue filter unit for allowing a blue light component of the light beam to pass through.
