摘要：
A zoom system for enlarging a portion of a video image chosen on a display screen by a cursor wherein the cursor is controlled by a remote position-dependent transmitter. An electrooptical arrangement receives positional signals from the remote transmitter causing the cursor to move on the display screen in relation to the movement of the remote transmitter. The cursor is used to select a portion of the displayed video image to be enlarged. Once chosen by the cursor, the selected portion of the video image is enlarged in a zoom circuit and shown on the display screen in place and stead of the original image.
