摘要:
The present invention provides a camera having a film feed mechanism comprising a microphone for sensing the surrounding noise around the camera, a noise level measuring portion for measuring the sensed noise (sound pressure), a noise level discriminator for comparing the measured noise level with a predetermined level to discriminate whether the measured noise level is higher or lower than the predetermined level, a feed mode change-over portion for changing the film feed speed to a silent mode or a normal film feed by selecting the normal film feed or the film feed whose generated noise level is low in response to the discriminated noise level, and a film feed mechanism for feeding a film in both winding and rewinding.
