摘要：
A gain adjustment unit includes: an analog total gain calculation section configured to calculate a total sum of analog gains on a way from photoelectric conversion output of an image pickup device to input of an analog/digital conversion circuit with use of picked-up images provided from the analog/digital conversion circuit, the analog/digital conversion circuit being configured to convert an output of an analog processing section into a digital signal, the analog processing section being configured to transmit and amplify an image pickup signal from the image pickup device, the image pickup device being provided at an insertion portion of an endoscope； and an adjustment gain calculation section configured to determine, as an adjustment gain, a difference between a target value of a total sum of gains on the way from the photoelectric conversion output of the image pickup device to the input of the analog/digital conversion circuit and the total sum of the analog gains, and output information of the adjustment gain to adjust an analog gain of the endoscope.
