Abstract
In a display device equipped with a picture-in-picture function, during controlling of the picture parameters of the main picture, one or several auxiliary pictures are presented on the screen, each having a certain combination of parameter settings. These may be preprogrammed, defined by a user, or automatically determined. The display device is provided with circuitry for transferring the parameter settings of one of the auxiliary pictures to the main picture. In a special embodiment, an auxiliary picture represents the parameter settings at the start of the picture parameter adjustment process. As a result, the old parameter settings may be compared with the new ones and, if so desired, may be reinstated in a simple manner.
