Claim 0:
1. An endoscope comprising:
a light source for an endoscope configured to emit illumination light having a controllable amount of light;
an image sensor configured to output an image pickup signal of an image obtained by receiving reflected light of the illumination light;
an optical sensor configured to receive a part of the illumination light of the light source;
a first temperature sensor configured to detect a first temperature of the light source;
a second temperature sensor configured to detect a second temperature of the optical sensor: and
a controller comprising hardware, the controller being configured to:
correct an amount of light received by the optical sensor based on the second temperature;
control driving of the light source so that an amount of the illumination light becomes a set value based on the corrected amount of received light and the first temperature; and
control, when a temperature of at least one of the first temperature or the second temperature becomes equal to or higher than a predetermined temperature, driving of the light source so that the temperature of the at least one of the first temperature or the second temperature does not exceed the predetermined temperature.
