Abstract

An electronic camera for use in incident light from various sources has a portion which produces a color image signal corresponding to an object in a field of view of the camera and having an adjustable white balance, a circuit which records the color image signal on a record medium, a first light receiving circuit which generates a first signal in response to the luminous intensity of the incident light in the mercury spectrum, a second light receiving circuit which generates a second signal in response to the luminous intensity of the incident light in the near infrared spectrum, and a circuit responsive to the relative values of the first and second signals and correspondingly adjusting the white balance to adapt the camera for use with incident light from a respective one of the sources.
