Abstract:
An image signal processing apparatus is arranged to convert input analog color-difference signals into digital color-difference signals, form a digital chrominance signal by using the digital color-difference signals, multiplex the formed digital chrominance signal onto the digital color-difference signals, convert the formed digital signal into an analog signal, and separate the analog signal into color-difference signals and a chrominance signal.
