Abstract: Because conversion from an invisible wavelength band to a visible wavelength band has been performed arbitrarily on a device-by-device basis, the color gamut in the visible color space could not be utilized sufficiently. A first aspect of the present invention provides an image-capturing device including: an image-capturing unit that is photosensitive to light in an invisible band; a generating unit that generates invisible wavelength information defined based on a sensitivity characteristic, which is an output characteristic of the image-capturing unit, to an object light flux wavelength for conversion of image-capturing data generated from an output signal of the image-capturing unit into visible color space image data; and a processing unit that relates the invisible wavelength information to the image-capturing data.

Abstract: An image processing device including means for: inputting two parallax images composed of images of first and second viewpoint directions; generating first and second smoothed images by applying, respectively to the images of the first and second viewpoint directions, a smoothing filter in a direction joining the first and second viewpoints; generating a reference image formed by a value based on a product of values of the first and second smoothed images; generating gain distribution data by dividing a value of the reference image by the value of the first smoothed image; performing gain correction of each pixel on the image of the first viewpoint direction, based on the gain distribution data; and outputting the gain corrected image of the first viewpoint direction as a parallax image, the smoothing filter having a filter diameter approximately equal to a parallax amount between the images of the first and second viewpoint directions.
