ABSTRACT:
A quotation or "comb teeth" pattern signal generating circuit of a video camera capable of obtaining a better quality of picture screen image by selecting the zebra pattern able to be seen by each stage by dividing the video signal gain band into each stage in the video camera. The invention includes: video signal amplifying means, NAM video signal means, video signal integrating means, zebra signal generating means, zebra signal control means, and monitor signal selecting means. According to the invention, since the picture screen condition and the light quantity state are easily caught in each gain band, a better quality of picture screen image is obtained, and separate measuring instrumentation or a master monitor is not required in order to measure the picture screen condition or the light quantity when taking a picture of a field location as in the prior art.
