An image signal processing device according to the present invention is a device for processing an image signal. The device is provided with a first differential amplifier for receiving a color-difference signal and a reference signal, a second differential amplifier for receiving a burst flag signal and the reference signal, and a modulator for receiving together signals outputted from the first and second differential amplifiers and modulating the received signals by using a carrier signal. Accordingly, it is possible to add the burst flag signal to the color-difference signal and modulate the obtained sum signal by means of a simple arrangement and without the need for complicated adjustment.
