In an image display apparatus of the present invention, at a predetermined timing, a characteristic data setting module actuates a reference image signal generation module to generate an analog reference image signal, based on reference image data prepared in advance. The characteristic data setting module then controls a signal selector module to select the analog reference image signal. An A-D converter module converts the analog reference image signal selected by the signal selector module into a digital image signal according to preset characteristic data. The characteristic data setting module adjusts the characteristic data set in the A-D converter module to make image data expressed by the digital image signal input from the A-D converter module into an image conversion processing module approach to the reference image data. This arrangement ensures easy adjustment of the operating characteristics of the image display apparatus.
