  • Image input device and image processing device
    Patent number: 9200895
    Abstract: An image input device capable of obtaining a luminance signal and a chromaticity signal appropriately even when photographing at nighttime is provided. Further, an image processing device capable of forming an image in which an object can be confirmed visually even under a low luminance environment is provided. Since a color space converting unit assigns weights to the visible light component and the infrared light component based on positional information acquired by the positional information acquiring unit, and converts the original image data into color space including the luminance signal and the chromaticity signal, it is possible to obtain the color space appropriately according to a height of the object and a distance to the object.
