PURPOSE:To make a video camera head small in size and light in weight by arranging a process circuit that adds and synthesizes a pixel clock, a composite synchronizing signal and a sensor output signal before camera process on a pedestal. CONSTITUTION:When a prescribed DC voltage is applied to a circuit block 50, the voltage is applied to a circuit block 49 on a panning turning head via an inductor 28 simultaneously and after noise is eliminated in a low pass filter 23 of the block 49 and converted into a desired DC voltage by a DC-DC converter 22. The DC voltage activates an electronic circuit of the block 49 and fed to a video camera connection terminal 10 and fed to a video camera head 48 through a cable 9 to activate the head 48. A microcomputer 7 of the camera head 48 is initialized after application of power. A burst pixel clock and a composite synchronizing signal are multiplexed onto a signal from a sensor before process and the process circuit is arranged to the pedestal side, then the video camera head can eliminate the process circuits to make it small in size light in weight. |
