Television signal pick up system

Abstract

Abstract PURPOSE: To enable to obtain the pick up output signal excellent in the vertical recolution, by converting the standard system output signal by sequential scanning sytem into the standard system TV signal with the readout and write-in to the frame memory. CONSTITUTION: The TV signal of sequential scanning is formed and the TV signal is once written in the frame memory 7. After that, it is read out from the memory 7 and converted into the TV signal of the m order interlace scanning, and also, the signal component of the n-th field at the TV signal of the m-th order interlace scanning is constituted with the line signal component read out from the memory 7 every (m-1) line sequentially from the n-th line at the TV signal of the m-th order interlace scanning. Thus, the standard system output signal by the sequential scanning system is converted into the standard system TV signal by the write-in and readout to the frame memory to obtain the pick up output signal excellent in the vertical resolution.
