Abstract:
    The invention relates to a digital camera adjustment device and adjustment system. This digital camera adjustment system consists of a digital camera and a digital camera adjustment device. Wherein, CCD is transformed into electrical signal by light from a luminophor and further transformed into digital signal via an A/D converter. A CPU of the digital camera calculates a proper gain, references an AWB evaluation value from an IPP under each lighting condition. A filter changeover device of the adjustment device selects a filter, calculates a proper gain for at least two colors, based on an AWB evaluation value from an IPP under each lighting condition, and sends a proper gain to the digital camera. The digital camera can properly reproduce white color, even if the color temperature of a light source is changed.
