Abstract
A digital video signal processing apparatus comprising a reproducer, an adder and a signal processor. The reproducer reproduces an analog signal of a still image recorded on a disk-shaped recording medium and converts it into a digital signal. The adder adds at least a predetermined number of digital signals for the same image from the reproducer, and then outputs an added digital video signal. The signal processor accomplishes digital video signal processing of the digital video signal derived from the adder.
