IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
First Claim
1. An image processing device, comprising:
- a spectral correction portion that inputs a mosaic image that is made up of a visible light component pixel in which mainly a visible light component has been captured and a non-visible light component pixel in which mainly a non-visible light component has been captured, and that generates spectrally corrected images in which spectral characteristics of each pixel have been corrected; and
a contrast enhancement portion that performs contrast enhancement processing on one of the spectrally corrected images that has been generated by the spectral correction portion and that includes the non-visible light component, and that generates a non-visible light component image in which contrast has been enhanced.

Abstract
A mosaic image is input that is made up of a visible light component image in which mainly a visible light component has been captured and a non-visible light component image in which mainly a non-visible light component has been captured, and spectrally corrected images are generated in which spectral characteristics of each pixel have been corrected. Contrast enhancement processing is then performed on one of the spectrally corrected images that has been generated and that includes the non-visible light component, and a non-visible light component image is generated in which contrast has been enhanced. A spectral correction portion generates the spectrally corrected images by performing a matrix computation that uses a spectral characteristics correction matrix M that is generated using information on ideal spectral characteristics.
