ABSTRACT:
A vertical line multiplication method and circuit multiplies the number of vertical lines of a video signal which is imaged by use of 4 CCDs to transform the video signal into another video signal having a higher resolution by controlling writing and reading of signals to and from memories. A first memory receives G1 channel data of a 0.5H period from a G1 CCD and outputs the written data at twice a speed of a writing speed. A second memory receives G2 channel data of a 1H period from a G2 CCD and outputs the written data at twice the speed of the writing speed. A selection device selects the data from the first and second memories alternately and outputs the selected signals sequentially as a wide bandwidth G signal.
