ABSTRACT:
A camera including a shutter that regulates the exposure time of the recording medium, a shutter measuring device that measures the time during which the shutter exposes the recording medium, a discerning device that discerns whether or not the recording medium is an infrared sensitive medium, and a suppressing device that suppresses the action of the shutter measuring device when the discerning device discerns that the medium is the infrared sensitive medium. This structure prevents the accidental sensitization of infrared film in the camera. In an alternative arrangement, a controller controls the operation of the shutter measuring device in accordance with either the type of recording medium or a voltage amount supplied to the shutter measuring device.
