Abstract
An image sensing system configured with a camera head-detachable image sensing apparatus and an image processing apparatus connected via a cable. The image processing apparatus generates a reference clock signal, and transmits it to the image sensing apparatus via the cable. The image sensing apparatus generates horizontal and vertical synchronizing signals on the basis of the received reference clock signal, and transmits the generated synchronizing signals to the image processing apparatus as a composite synchronizing signal. The image processing apparatus separates the composite synchronizing signal into the vertical and horizontal synchronizing signals, then transmits a control signal for controlling the image sensing apparatus during the vertical blanking period. The horizontal and vertical synchronizing signals are also provided to a VIDS circuit of the image sensing apparatus, and the control signal is multiplexed to an image signal during a vertical blanking period by the VIDS circuit and an adder. The image processing system separates the control signal from the inputted image signal and performs corresponding processes on the respective separated signal.
