Abstract
An apparatus for measuring image qualities of a color display unit includes a color video camera for imaging a display screen of a first color display unit, a central processing unit for measuring image qualities of the display screen of the first color display unit based on an image signal generated by the color video camera, a second color display unit for displaying data of the image qualities measured by the computer, and an image signal generator controllable by the central processing unit for generating an image signal required to measure the image qualities and supplying the image signal to the first color display unit. The central processing unit supplies the image signal generated by the color video camera to the second color display unit to display an image of the display screen of the first color display unit in a predetermined display area on a display screen of the second color display unit for relative positional adjustment between the first color display unit and the color video camera.
