Abstract

Provided is an image input device capable of generating a luminance signal having a high ratio of S/N of an image, and further capable of providing the image with a little uncomfortable feeling even in the night time when the amount of photons is few, wherein, when a visible light luminance signal is relatively low, and an infrared component is predominant in an original image component, for example, correcting color-difference signals with added luminance prevents the color-difference signals with the added luminance from being too high, thereby it becomes possible to perform more natural color reproduction, which is close to original visible light, and gives a little uncomfortable feeling.
