Abstract:
1. An imaging device comprising: a color image sensor having a first color component pixel, a second color component pixel, and a third color component pixel including more intensity concerning luminance information than said first color component pixel and said second color component pixel, said first to third color component pixels being regularly arranged in a two-dimensional matrix, each of said first to third color component pixels generating a pixel signal in accordance with an amount of light received, and said color image sensor transferring and outputting said each pixel signal in succession; a difference estimating section estimating difference in a signal level exerted on said pixel signal of said third color component pixel, with the use of said pixel signal of a pixel peripheral to said third color component pixel; a correcting section correcting said pixel signal of said third color component pixel using said pixel signal of said third color component pixel and a coefficient provided on the basis of the estimated difference; and a judging section judging whether or not a level of said pixel signal is equal to or more than a predetermined value A, the level of said pixel signal being transferred from a pixel immediately preceding said third color component pixel in transfer order in said color image sensor, and said judging section causing said correcting section to operate only when the judged level is equal to or more than said predetermined value A.
