Abstract
To provide an image pickup system having CCDsdriven at different frequencies respectively which can drive each CCDwith a predetermined frequency if a detachable camera head (or electronic endoscope)is used and also can process a signal processing clock of a video processing circuitwith one type of clock. A drive signal of the predetermined frequency supplied to the CCD is produced via a generating circuit CXOin the video processing circuit, a frequency dividing circuitand a timing generator (T.G.). A CCD signal outputted from the CCDis inputted to a line memoryin a floating circuit. As a writing clock (WCK) of the line memory, the one which is divided in the frequency dividing circuitto a frequency in accordance with the CCDto be used is used, and as a reading clock (RCK), the one of one type of frequency is used without regard to the CCDto be used. Hence, it is possible to perform the signal processing of a secondary circuitof the line memoryand following ones always with a common generating clock.
