An adjusting method for endoscope systems comprises a first adjusting step, a second light adjusting step and a storing step. Additionally, the bodies of the two PFETs are electrically connected to VDD. The first pixel is consisted of a green filter, a blue filter and a transparent filter. Although some types of processing are allowed when the device is in a status in which the time information is based on the time data acquired from the external time information generator, the same type of processing are disabled when the device is in any other status associated with time information. The first and second translating devices preferably comprise robotic arms. The control level can also be fed to the actual VGA to control its gain.
