Image sensor and electronic device comprising the same

An image sensor comprising:

• a first group of pixels including a first color filter passing light having a first wavelength range;
• a second group of pixels including a second color filter passing light having a second wavelength range;
• and
• a third group of pixels including a third color filter passing light having a third wavelength range,
• wherein the first wavelength range is longer than the second wavelength range, and the second wavelength range is longer than the third wavelength range,
• wherein a second pixel in the second group of pixels or a third pixel in the third group of pixels includes a plurality of photoelectric conversion devices, and a first pixel of the first group of pixels includes a single photoelectric conversion device, and
• wherein each pixel in the second pixel group and the third pixel group includes two photoelectric conversion devices.
