Kind Code:
B2
Abstract:
PURPOSE:To perform a correct signal processing by providing a head part consisting of an optical system and a solid-state image pickup element, a synchronizing and drive signal generating circuit, a control part consisting of a signal processing circuit and a multi-conductor cable. CONSTITUTION:Signals T2, T3 are respectively inputted to a sample holding circuit 36 through buffer circuits 41, 42 of a camera control part 34. A waveform of the signal T3 is shaped according to a certain reference level and the picture signal T2 is processed based on the waveform shaped signal T3. Namely, the signal T3 is used for reading the picture signal T2 and guided to the camera control part 34 through the same type of a transmission system as the picture signal T2, so that a phase thereof coincides with that of the picture signal T2, and a synchronizing signal processing can be performed without requiring a phase correction. After the detection of an effective signal of the picture signal T2 and the removal of noise are carried out, the signal T3 is converted to a standard television signal by a process circuit 37 and outputted. Thereby, the correct signal processing can be performed.
