VIDEO CAMERA FOR PAL, SECAM

摘要

PURPOSE:To realize a camera for both PAL, SECAM by obtaining PAL system image signals in a video camera device and obtaining SECAM system image signals by using modulate signals to be produced in the process. CONSTITUTION:A switch 8 is switched to the SECAM side in case of using an SECAM camera. Luminance signals from a process amplifying part are added to a blanking circuit 2 through a dalay line 1, and outputted with the blanking added to them. Color difference signals from the process amplifying part are modulated into PAL by a PAL modulator 3 and added to a PAL demodulator 5 through BPF4 to be demodulated in a base band. The color signal thus demodulated are modulated into SECAM by an SECAM modulator 6 and are synchronized with the luminance signals throught the BPF7 and the switch 8 to be outputted as image output signals for SECAM.
