Imaging device

A color image sensor has a first, second, and third color component pixels. The third color component pixel includes more intensity information than the first and second color component pixels. A difference estimating section estimates difference in a signal level exerted on a pixel signal of the third color component pixel, using the pixel signal of a pixel peripheral to the third color component pixel. A correcting section corrects the pixel signal of the third color component pixel on the basis of the estimated difference. Accordingly, when the third color component is green in a Bayer array, a pixel signal of a green pixel in a row of red pixels becomes equal to the pixel signal of a green pixel in a row of blue pixels. Therefore, line crawling can be suppressed without smoothing an image.
