Abstract
The amount of slant of an entire video camera in the vertical direction is detected by a slant detector by detecting a horizontal and vertical signal quantity or by a mechanical vertical direction detector and a memory controller reads out the video signal while controlling the address of the memory so as to correct the slant of the video signal stored in the memory depending on the slant amount, and since the memory is composed of two memory systems the slant may be always corrected for a real time in moving picture, thereby presenting a stable video output.
