发明名称 IMAGING APPARATUS AND METHOD FOR CONTROLLING WHITE BALANCE
摘要 An imaging apparatus has: a white balance control circuit for detecting an achromatic portion of an image of an object and controlling gains of the chrominance; an object distance detecting circuit for detecting a distance to the object; and a zoom value detecting circuit for detecting a zoom value of the optical system. The imaging apparatus further has: an object brightness detecting circuit for detecting brightness of the object; and a white balance control amount adjustment value setting circuit for forming a white balance control amount adjustment value to adjust a control amount in the white balance control circuit on the basis of object brightness information, object distance detection information, and zoom value information, wherein the white balance control amount is adjusted on the basis of the white balance control amount adjustment value.
