ABSTRACT:
Color temperature is calculated on the basis of image data captured by a CCD. An appropriate exposure value is calculated on the basis of a brightness component of the image data. It is determined whether or not LEDs should emit auxiliary lights to obtain the appropriate exposure value. When it is determined that the LEDs are required to emit, light quantity of the combined light to be emitted by the LEDs is calculated. The light quantities of the respective LEDs are set such that the emission ratio of the LEDs corresponds to the calculated color temperature. The LEDs emit the lights at the set light quantities. The captured image is adjusted based on the calculated color temperature.
