Document Type and Number:
Japanese Patent JP4106774
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it possible to accurately focus a small and white object in the case of setting up the white balance in a digital camera. SOLUTION: In the case of setting up a white balance by a manual mode, the digital camera 1 sets up the focal distance and focal position of a photographing zoom lens to respective prescribed values. When a small and white object such as a business card held by a photographer's left hand is photographed by the camera 1 held by his (or her) right hand, the camera 1 calculates its white balance based on obtained picture data and stores the value. A white balance control circuit 107 accesses the stored white balance control value and executes white balance control for an object image to be picked up based on the white balance.
