1. An image sensor comprising:
a pixel array comprising:
a first pixel group comprising a plurality of first color pixels having a first color and outputting a first pixel signal for the first color;
a second pixel group comprising a plurality of second color pixels having a second color different from the first color and outputting a second pixel signal for the second color; and
a third pixel group comprising a plurality of third color pixels having a third color different from the first and second colors and outputting a third pixel signal for the third color; and
an image signal processor configured to receive the first pixel signal, the second pixel signal, and the third pixel signal from the pixel array,
wherein the image signal processor, based on the first pixel signal being determined as a bad pixel signal, is configured to generate a corrected pixel signal for the first through third colors by performing bad pixel correction on the first pixel signal based on the second pixel signal and the third pixel signal, and generate a remosaiced pixel signal for the first through third colors by remosaicing the third pixel signal based on the second pixel signal and remosaicing the second pixel signal based on the third pixel signal,
wherein the plurality of first color pixels, the plurality of second color pixels and the plurality of third color pixels are arranged in a first pattern in the pixel array, and
wherein the corrected pixel signal and the remosaiced pixel signal represent information in which the first through third color pixels are rearranged in a second pattern having a higher frequency than a frequency of the first pattern.
