Abstract
Video camera which emphasizes an outline of a video signal produced thereby. A detail signal of a video image represented by the video signal is generated and which represents a vertical outline emphasis signal. Edges of the video image and burst-like portions of the video signal are detected, and an edge detection signal is generated that corresponds in one manner to the detected edges and that corresponds in another manner to the detected burst portions. The detail signal is adjusted by the edge detection signal or by a cross color suppression signal generated from the vertical outline emphasis signal. The video signal then is modified by the adjusted detail signal so as to produce the outline emphasized video signal. The detail signal may also be adjusted by a gain setting signal that corresponds to the vertical outline emphasis signal and which is compressed in level when the vertical outline emphasis signal is relatively low.
