Abstract
A camera comprises a liquid-crystal display device and a liquid-crystal control section. The liquid-crystal display device has a liquid crystal whose transmittance is variable. The liquid-crystal control section, in the photograph enable mode, brings the liquid crystal of the liquid-crystal display device into the light-transmitting state and, in the photograph disable mode, brings the liquid crystal of the liquid-crystal display device into a half light-transmitting state or the no-light-transmitting state.
