The image processing method and device photograph a subject or transparent image to acquire calorimetric values of a subject image, acquire chromaticity information and illuminance information of a light source illuminating the subject and the transparent image, perform on the calorimetric values of the subject image chromatic adaptation correction based on the chromaticity information and the acquired illuminance information and contrast correction based on the illuminance, and correct the corrected calorimetric values to be output by an amount of flare in outputting the subject image, thereby enabling faithful reproduction of appearance. The method and device further perform at least one of contrast conversion and chroma conversion on the calorimetric values of the subject image based on a chromaticity value in a case where a degree of adaptation or an adaptation luminance is set higher than that determined for an illuminating color of the light source before performing the chromatic adaptation correction, thereby enabling faithful reproduction of appearance and preferred color reproduction of appearance.

A light-scattering film is provided and includes a transparent support having thereon at least a light-scattering layer. When substantially parallel light is incident on a surface of the film at an incident angle of 5°, the reflectance for an angle θ in the light-receiving part measured in a plane containing the film normal line and the incident direction is R(θ), the value obtained by normalizing R(θ) by the reflectance of regular reflection is Rrel(θ), and the value calculated from the maximum variation |dRrel(θ)/dθ|max for the angle θ is a scattering coefficient A (formula 1), the reflection coefficient B (formula 2) calculated from the scattering coefficient A and the 5° specular reflectance Rs is from 2.0 to 5.0. Scattering coefficient A=1/(10×|dRrel(θ)/dθ|max) (Formula 1) Reflection coefficient B=2.2×log 10(Rs)−7.5×log 10(A)+5.9 (Formula 2)

The multi-band image photographing method and apparatus photograph a subject by dividing a photographing wavelength region into plural bands and obtain spectral images of the subject corresponding to the respective divided plural bands. The method and apparatus detect a sensitivity balance among the respective plural bands from photographing data of each of the spectral images obtained by preliminary photographing performed prior to main photographing, determine photographing conditions for the respective plural bands based upon the detected sensitivity balance, and perform the main photographing in accordance with the determined photographing conditions to photograph a multi-band image. The program is used to cause a computer to execute this method or part thereof.

Provided is an optical device, comprising a plurality of polarizers that are arranged along a propagation direction of incident light; a first phase element that is disposed between the plurality of polarizers and that has a phase lag axis forming a prescribed angle relative to transmission axes of the polarizers arranged along the propagation direction; and a second phase element that is disposed between the first phase element and one of the polarizers arranged along the propagation direction, and that provides the incident light with a prescribed phase difference. An angle of the phase lag axis of the second phase element is adjusted such that the optical device transmits light in a prescribed wavelength region in the incident light.

The position identifying system identifies a position of an object existing inside a body. The position identifying system includes a vibrating section that vibrates each of a plurality of different positions inside the body at a different timing; an image capturing section that captures a frame image of the object at each of the different timings; and a position identifying section that identifies the position of the object based on a blur amount of an image of the object in each frame image captured by the image capturing section.
