IMAGE INPUT DEVICE

Provided is an image input device capable of generating a luminance signal having a high ratio of S/N or an image, and further capable of providing the image with a little uncomfortable feeding 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.

IMAGE INPUTTING APPARATUS

Provided is an image inputting apparatus wherein luminance signals having a high S/N ratio can be generated even during nighttime with a small quantity of photons. An imaging element (3) images image components (ITe, R, IR, W). A color signal generating section (42) generates color signals (dR, dG, dB) from the image components (Ye, R, IR, W). A color space conversion section (43) converts the color signals (dR, dG, dB) into a color space that includes luminance signals and color difference signals. The color space conversion section (43) calculates a luminance signal (Yadd) obtained by adding the image components (Ye, R, IR, W), as the luminance signal of the color space to be converted.
