Image capture device and control method thereof

A control method for an image capture device, comprising:

• providing a storage for storing control tables;
• capturing information under current ambient illumination conditions via an image capture unit;
• calculating current ambient illumination conditions of the captured information;
• determining whether the current ambient illumination is sufficient;
• and
• compensating the current ambient illumination to a corresponding control table if the current ambient illumination is not sufficient.

An image capture device, comprising:

• an image capture unit configured for capturing image information in current ambient illumination conditions;
• a calculation unit configured for reading the information and calculating brightness of the current ambient illumination based upon the information;
• an assist light configured for compensating current ambient illumination;
• a determination unit configured for determining whether the current ambient illumination is sufficient and determining whether the current ambient illumination has been compensated;
• a storage unit configured for storing a first control and second control tables;
• a first assist light control unit configured for acquiring a corresponding setting in the first control table using the calculated current ambient illumination, and setting the assist light using the acquired setting;
• a second assist light control unit configured for acquiring a corresponding setting in the second control table using the calculated current ambient illumination, and setting the assist light using the acquired setting;
• and
• a processing unit configured for activating the first assist light control unit if the current ambient illumination has not been compensated or the second assist light control unit if the current ambient illumination has been compensated.
