An adjustable anamorphic transformer comprises a source of video signals, which are primarily - but not exclusively - images of a human brain. The video signals have their horizontal and vertical synchronizing signals separated out and then independently processed. The video signals themselves are amplified with an automatic gain control. An electronic means jointly responsive to the separately processed horizontal and vertical signals controls the gain of the video amplifier. Other electronic means separately responsive to the horizontal and vertical signals independently control, in X and Y axes, the expansion of images produced responsive to the video signals.
