ABSTRACT:
A color television camera of the phase-split type is disclosed wherein an index signal derived by horizontally scanning an index-generating section, produced at the beginning or end portion of vertical scan for an image pickup tube, is converted to a low-frequency signal by a frequency converter so that a low-frequency index signal in at least one horizontal scan period is written into a memory circuit, and the low-frequency index signal is read out for each horizontal scan to produce a standard color television signal from two color-difference signals. The two color-difference signals are derived by processing a modulated color signal, which has been space-modulated by a stripe filter disposed in front of the image pickup tube, and a low-frequency signal or a brightness signal derived from the image pickup tube.
