ABSTRACT OF THE DISCLOSURE A plurality of images superimposed to form a composite image on the screen of a television monitor are brought into convergence (register) by forming a reference image on the screen, the reference image including a plural- ity of reference points, and superimposing a test image on the reference image. The test image is similar to the reference image and includes a plurality of adjustment points respectively corresponding to the reference points. The test image further includes at least one correction portion corresponding to a given portion of the reference image, the correction portion including a given subset of the adjustment points. An adjustment point is selected within such subset, the position of the selected adjustment point is adjusted with respect to the reference point corresponding thereto, and the positions of the other points within the correction portion are simultaneously and proportionally adjusted, thereby establishing a substantial convergence of the correction portion with respect to the given portion of the reference image. The process is repeated for other corresponding image portions as necessary to establish substantial convergence of all corresponding portions of the two images. In the same manner convergence of a third image with the first two is established. -1-
