摘要： 57 An electronic camera for use with incident light from various sources comprises means (9) which produces a colour image signal corresponding to an object in a field of view of the camera and having an adjustable white balance, a circuit (10) which records the colour image signal on to a record medium (11), a first light receiving circuit (25) which generates a first signal in response to the luminous intensity of the incident light in the mercury spectrum, a second light receiving circuit (26) 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 for correspondingly adjusting the white balance to adapt the camera for use with incident light from a respective one of the various sources.
