PROJECTOR, PROJECTION SYSTEM, IMAGE DISPLAY CONTROL METHOD, AND PROGRAM MAKING COMPUTER IMPLEMENT IMAGE DISPLAY CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a projector that improves moving image visibility and secures lightness of a projection image.;SOLUTION: A control means 6 of the projector which modulates luminous flux emitted by a light source according to an input image signal to form and project an optical image includes image signal analyzers 65 and 66 which analyze the input image signal by image data in frame units, image display rate setters 67 and 68 which set image display rates as rates of image display periods of a first optical device 2 and a second optical device 3 in a frame update period based upon analysis results of the image signal analyzers 65 and 66, and a display controller 71 which determines whether the sum of the image display rates of the first optical device 2 and second optical device 3 set by the image display rate setters 67 and 68 exceeds 1, and controls image display by the first optical device 2 and second optical device 3 based upon the determination result.;COPYRIGHT: (C)2010,JPO&INPIT
