Alienating in the illuminant brightness equalization device and manner of the digital image test component and the digital image hue test device and the mannered

摘要

An illumination equalizing device includes a polygonal rotary column (200) disposed in a sealed space, equipped with light sources, and rotatable at specific angular intervals, light sources (210) radiating light onto an image test member (220) attached to a wall of the sealed space for testing a digital image, the light sources (210) mounted on side surfaces of the polygonal rotary column (200), illuminometers (222, 224, 225, 227, 229) measuring illumination values of light radiated onto the image test member (220), and a rotary column control unit (260) rotating the polygonal rotary column (200) at set angular intervals so that the illumination values measured by the illuminometers (222, 224, 225, 227, 229) are equalized. A method for equalizing the illumination of light sources (210) for a digital image test member (220), and an apparatus and method for testing the color of a digital image uses the illumination equalizing device.
