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.
Dispositif de traitement de signaux d'image. Comprend un premier amplificateur différentiel pour recevoir un signal de différence de couleur et un signal de référence, un deuxième amplificateur différentiel pour recevoir un signal indicateur de salve et le signal de référence, et un modulateur pour recevoir ensemble les signaux de sortie du premier et du deuxième amplificateurs différentiels et moduler les signaux reçus au moyen d'un signal de porteuse. Il est ainsi possible d'ajouter le signal indicateur de salve au signal de différence de couleur et de moduler le signal combiné obtenu au moyen d'un simple arrangement, sans avoir à effectuer un réglage compliqué.
