Abstract:
An image sensor, an image processing apparatus including the same and an interpolation method of the image processing apparatus are provided. The image sensor includes a plurality of pixels that include a low-luminance pixel including a first photoelectric conversion device that accumulates a charge less than a predetermined reference value and a high-luminance pixel including a second photoelectric conversion device that accumulates a charge more than the predetermined reference value. Interpolation is carried out giving more weight to the low-luminance pixel at low luminance and giving more weight to the high-luminance pixel at high luminance, so that a higher SNR is obtained.
