ABSTRACT:
A manually adjusted echocardiogram machine for a display device is converted to automatic by providing servo adjustment in place of manual adjustment for regional and global brightness controls. A computer is programmed to make rapid sequential comparison of relative brightness of pixels within defined areas of the display controlled by each of the respective controls. The output for each of the areas is compared with a predetermined standard in a computer program to produce a correction signal, for example, incrementally moving toward correction of a particular region's brightness. The computer program controls sequence and distributes correction signals.
