PROBLEM TO BE SOLVED: To uniformize current consumptions at start-up and normal-operation by correcting an unintended decrease state of the current consumption at the start-up of an image pick-up device.SOLUTION: An endoscope includes: a VDD line disposed in an image pick-up device for supplying a prescribed power voltage to the image pick-up device a power current correction part 150 that is provided in the image pick-up device and corrects a load of the VDD line so as to change a current flowing through the VDD line according to a prescribed control signal and a power current control part 160 that is provided in the image pick-up device, generates a prescribed control signal for increasing a current flowing through the VDD line at the start-up of the image pick-up device relative to a current flowing through the VDD line in the normal operation of the image pick-up device, and outputs the control signal to the power current correction part 150 at prescribed timing.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】撮像素子の起動時における意図しない消費電流の低下状態を是正し、起動時と通常動作時とで消費電流を一定化する。【解決手段】撮像素子内に配設され、電源から撮像素子に対して所定の電源電圧を供給するためのVDDラインと、撮像素子に設けられ、所定の制御信号に応じてVDDラインに流れる電流を変化させるように当該VDDラインの負荷を補正する電源電流補正部150と、撮像素子に設けられ、撮像素子の起動時においてVDDラインに流れる電流を、撮像素子の通常動作時においてVDDラインに流れる電流に対して相対的に増加させるための所定の制御信号を生成し、所定のタイミングにおいて電源電流補正部150に対して当該制御信号を出力する電源電流制御部160と、を具備する。【選択図】図2
