A CAMERA MODULE FOR AUTOMATICALLY ADJUSTING BRIGHTNESS

摘要

PURPOSE: A camera module for automatically controlling brightness is provided to control brightness by controlling a control signal of an image sensor corresponding to illuminance of external environment. CONSTITUTION: An image sensor(110) photographs images of a front side or a back side of a vehicle. An illuminance sensor(120) senses external brightness of the vehicle. A control unit(130) transmits a control signal to the image sensor corresponding to the sensed brightness. The image sensor changes a setting value corresponding to the control signal. The image sensor controls brightness of a photographed image corresponding to the control signal. [Reference numerals] (110) Image sensor; (120) Illuminance sensor; (130) Control unit; (140) Memory
