DEVICE AND METHOD FOR UNIFORMIZING LUMINOUS INTENSITY OF LIGHT SOURCE OF DIGITAL IMAGE TEST MEMBER, AND DEVICE AND METHOD FOR DIGITAL IMAGE HUE TEST USING IT

摘要

PROBLEM TO BE SOLVED: To provide a device and method for uniformizing luminous intensity of a light source of a digital image test member for uniformizing the luminous intensity of an artificial light source, while keeping a color temperature constant, and a device and method for a digital image hue test utilizing the device and method for uniformizing the luminous intensity of the light source of the digital image test member, constituting various artificial light sources usable in a range from a low-illuminance environment to a high-illuminance environment, while keeping the color temperature constant by various color temperatures.;SOLUTION: The device for uniformizing the luminous intensity of the light source of the digital image test member includes a polygonal rotating column installed in a sealed space, rotatable at each prescribed angle; a plurality of light sources for irradiating light to an image test member attached to one surface of the sealed space in order to test a digital image, mounted on each face of the polygonal rotating column; a plurality of illuminance measuring devices for measuring the illuminance of light irradiated to the image test member; and a rotating column control part for rotating the polygonal rotating column at each prescribed angle so that each illuminance value measured by the illuminance measuring devices becomes uniform.;COPYRIGHT: (C)2008,JPO&INPIT
