ABSTRACT:
A white balance adjusting device includes a dichroic prism for dividing light reflected from an object into a green-component, a red-component and a blue-component. These primary color components are incident on a first CCD, a second CCD and a third CCD. Based on photometry data from a photometry sensor, an electronic charge accumulating period for the first CCD corresponding to the green-component is determined. Based on a colorimetry by a colorimetry sensor, electronic charge accumulating periods for the second CCD corresponding to the red-component and the third CCD corresponding to the blue-component are determined. When the color temperature is high, the electric charge accumulating period for the second CCD is set to be relatively long, and the electric charge accumulating period for the third CCD is set to be relatively short.
