Abstract
An image transmission system includes a modulating part for independently modulating a luminance signal and two kinds of color difference signals and a demodulating part for independently demodulating the modulated luminance signal and the two kinds of modulated color difference signals. The demodulating part includes a signal correcting part for shifting at least one of the modulated luminance signal and the two kinds of modulated color difference signals by a predetermined number of picture elements in a scanning line direction to correct an error introduced by the modulation.
