Abstract
An image parameter adjustment system for use with a video display having a display surface area. A video image processing unit is connected to the video display and adapted to control the appearance of a video image displayed on the video display. The appearance of the image is controlled, at least in part, by the value of at least one user-adjustable display parameter. The video image processing unit includes an adjustment mode in which the image processing unit is configured to control the appearance of the video image by varying, over the display surface area, the value of the user-adjustable parameter in a range around a current value so that a viewer can see the effect that changing the value of the adjustable parameter in either direction would have on the displayed video image.
