Abstract: An image sensor includes a pixel array in which pixels having photoelectric conversion elements are arranged in a matrix, color filters corresponding to the pixels and configured to selectively transmit light of at least two different wavelength bands, and microlenses on the color filters. At least some of the microlenses may have different shapes depending on respective wavelength bands that respective corresponding color filters at least partially overlapping with the at least some microlenses are configured to selectively transmit, such that the at least some microlenses are configured to compensate for chromatic aberration between the lights passing through the respective corresponding color filters.
