Abstract
Improvement of image quality is realizable. An adding unit generates a summed value corresponding to a sum of all values of respective pixel signals of a plurality of first pixels each of which has sensitivities to visible light and invisible light. The values are weighted by first weighting coefficients that are different from each other and determined such that a difference between a sum of the sensitivities of the first pixels to the visible light and a sensitivity of a second pixel to the visible light, which second pixel has sensitivities to the visible light and the invisible light, becomes smaller than a predetermined tolerance in a state that the sensitivities of the first pixels to the visible light are weighted by the first weighting coefficients and that the sensitivity of the second pixel to the visible light is weighted by a second weighting coefficient. A weighting processing unit weights a pixel signal of the second pixel by the second weighting coefficient. An invisible light component generation unit generates, as a component of the invisible light within each of the pixel signals, a difference between the weighted pixel signal of the second pixel and the summed va…
