Abstract
In a digital camera, a pre-measuring device obtains color temperature information according to external light in a preliminary exposure. A white balance control value is then determined. The white balance is subsequently adjusted when a strobe light is generated. A regular exposure is thereafter made using the strobe light and the image is recorded for future processing.
