PROBLEM TO BE SOLVED: To avoid trouble or inconvenience to others. SOLUTION: In a camera emitting signal sounds, a surrounding noise is measured by a microphone and a signal sound such as a shutter sound is automatically set to a proper volume. This makes it possible for a user to listen to the signal sound with a volume that is not a noisy level and to prevent the user from losing a shutter chance. COPYRIGHT: (C)2007,JPO&INPIT |
