摘要

PROBLEM TO BE SOLVED: To realize an inexpensive device for adjusting distortion of image displayed on screen that an operator even without special technology can handle and maintain without the need for calibration of image distortion reference data. SOLUTION: The displayed image distortion adjustment device 1 that adjusts distortion of an image of a display device 9 to be adjusted whose image distortion is to be corrected according to external control, is provided with a touch panel section 2 through which light is transmitted and that enters displayed image position information through the selection of the displayed image on the display device 9 to be adjusted on the basis of the transmitted light, displays an image distortion reference and enters the image distortion reference through the selection of the displayed image distortion reference and the processing section 7 that compares the display image position information and the image distortion reference position information entered from the touch panel section 2 and matches the image distortion on the display device 9 to be adjusted with the image distortion reference as its control on the basis of the comparison result.
