ABSTRACT:
Disclosed is an apparatus for and method of stabilizing a picture in an image system during the changing of a broadcast channel. Since channel altering causes noise in synchronization, and an unstable picture when performing automatic frequency tuning (AFT) and automatic gain control (AGC), an image signal of the previous channel is stored in an image memory before being changed, and output onto the screen using a switch controlled by a microcomputer during the unstable period for AFT and AGC, instead of the image signal of the altered channel. The image signal of the altered channel is output after the output of an automatic controlled is stabilized.
