Abstract
A camera has a liquid-crystal display device including a liquid crystal whose transmittance is variable. A sensing section senses an abnormality in the camera. A liquid-crystal control section, in a release signal wait mode, brings the liquid crystal of the liquid-crystal display device into a light-transmitting state and, when the sensing section has sensed an abnormality in the camera, changes the transmittance of the liquid crystal of the liquid-crystal display device.
