Title: IMAGE INPUT DEVICE
Abstract:
Provided is an image input device capable of obtaining information necessary for creating an appropriate color image even if a pixel has been saturated, wherein the coordinates of the saturated pixel and a high-luminance pixel are compared with each other from an image (Img2) (or an image (Img0)) obtained by performing imaging at a first shutter speed, and an image (Img1) obtained by performing capturing at a second shutter speed. Pixels having the same coordinate are estimated to have captured the same subject, and a saturated region color correction circuit (108) adjusts chromaticity included in the signal from the saturated pixel of the image (Img2) (or the image (Img0)) having the same coordinate in such a manner as to meet chromaticity included in the signal from the high-luminance pixel of the image (Img1).
