ABSTRACT:
In a color television camera apparatus, a 2fs-rate luminance signal and fs-rate chrominance signals are selectively generated by a matrix circuit 8, in conformity with a plurality of standard systems, from 2fs-rate three-color image pick-up signals generated by an image signal pick-up unit. The fs-rate chrominance signals are modulated by a modulating circuit 12 into fs-rate modulated chrominance signals which are converted by a rate converter 13 into 2fs-rate modulated chrominance signals. The 2fs-rate luminance signals and the 2fs-rate modulated chrominance signals are combined by an adder 14 into 2fs-rate digital composite video signals which are converted by a D/A converter 15 into analog composite video signals. In this manner, analog composite video signals, in which the bandwidth of the luminance signals has been enhanced up to the sampling frequency fs, may be selectively outputted in conformity with a plurality of standard systems.
