Abstract

PURPOSE:To obtain a picture featuring a high S/N ratio when the inside of the cavity in the organism or the machine device is picked up by the solid pickup element, by controlling the illumination beam according to the output level of the pickup element and at the same time giving the control to the charge storage period. CONSTITUTION:The driving pulse is sent to pickup element 2 within endoscope 1 from driving circuit 4 to start the charge storage. And at the same time, the output of photo detector 3 is integrated through integrating circuit 5. And when the output signal of the integration reaches reference level VR at the t1 time within the storage period and due to the overexposure, the illuniation of light source unit 7 is stopped by the signal from control circuit 6 to perform the transfer after the T1 time. In case the incident light is weak and thus does not reach the reference level within the fixed time and in case the output signal reaches the reference level within the t2 time covering over several frames, the transfer is given to TV picture receiver 8 during the transfer period of the final frame to obtain the reproduced image. And in the case of the charge storage over several frames, memory 9 is provided to avoid the lack of the picture signals during that time. And switch SW gives the switching to memory 9.
