摘要：
A camera includes a liquid-crystal display device with a liquid crystal whose transmittance is variable. A liquid-crystal control section, in a release signal waiting mode, brings the liquid crystal of the liquid-crystal display device into the light-transmitting state and, when a release signal is output to turn on an exposure mode, lowers the transmittance of the liquid crystal of the liquid-crystal display device temporarily.
