Abstract
Abstract This invention relates to a camera in which the color of a photographing light source is colorimetered to thereby obtain colorimetry information. This invention provides a camera of the above-described type in which provision is made for a sensor for measuring the colors of the photographing light source in different directions from the camera and the direction to be measured by the sensor is detected and is designated on the basis of the object distance and the color of the light source in the designated direction.
