Document Type and Number:
Japanese Patent JP3700623
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make adjustment easy when vertical and horizontal trapezoidal distortions are compensated individually.
SOLUTION: The projection image display system includes image display devices 9r to 9b, circuits 2 to 7 for displaying a prescribed image by driving the image display device on the basis of an input image signal, and a light source for projecting the display image of the image display device through light. The circuit includes a circuit 5 for carrying out image conversion process according to the outer operation by fixing the compensation ratio of trapezoidal distortion in one direction (for example, vertical direction) out of vertical and horizontal directions of the projection image, and changing the compensation ratio of trapezoidal distortion in the other direction (for example, horizontal direction).
