CROSS REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Phase of International Patent Application No. PCT/JP2017/000011 filed on Jan. 4, 2017, which claims priority benefit of Japanese Patent Application No. JP 2016-006374 filed in the Japan Patent Office on Jan. 15, 2016. Each of the above-referenced applications is hereby incorporated herein by reference in its entirety.

TECHNICAL FIELD

The present technology relates to an image processing device, an image processing method, and an imaging device, and especially relates to an image processing device, an image processing method, and an imaging device which enable high-precision image processing.

BACKGROUND ART

Conventionally, a method of performing image processing using not only an image signal by visible light but also an image signal by infrared light is proposed (refer to, for example, Patent Document 1).

Herein, in a field of image processing, a false color is known in which a color which is not actually present is reproduced. Even in the method proposed in Patent Document 1, it is impossible to avoid occurrence of the false color in principle. Also, depending on the image processing, there is a case where an artifact in which a pattern different from an actual pattern appears occurs in the processed image.

SUMMARY OF THE INVENTION

Problems to be Solved by the Invention

By the way, when the false color and the artifact occur, they give a sense of discomfort to a user who looks at the image, and it is supposed to be a cause of deterioration in sensing performance in recently developed sensing purposes. Therefore, a technology of enabling high-precision image processing for suppressing occurrence of the false color, the artifact and the like is demanded.

The present technology is achieved in view of such a situation, and an object thereof is to perform high-precision image processing.

Solutions to Problems

An image processing device according to a first aspect of the present technology is an image processing device provided with an image generation unit which generates a high-resolution image obtained from a spectral component of a wavelength band of invisible light, the high-resolution image resolution of which is higher than resolution of an image of a subject obtained from a spectral component of a wavelength band of visible light on the basis of a projection image obtained by projecting light of the wavelength band of the invisible light to the subject.

The image processing device according to the first aspect of the present technology may be an independent device or may be an internal block which forms one device. Also, an image processing method according to the first aspect of the present technology is an image processing method corresponding to the image processing device according to the first aspect of the present technology described above.
