SOUND RECORDING CAMERA
Document Type and Number:
Japanese Patent JPH0528635
Kind Code:
A
Abstract:
PURPOSE:To enable a natural sound recording without an interruption during the sound signal recording in a photographying by repeatedly overwriting the sound signals in a buffer memory prior to inputting a recording start signal. CONSTITUTION:During the recording of a sound in a photographying, a sound detecting means 4 detects no sound sections and the signals without surrounding noise are repeatedly overwritten in a portion of a buffer memory 6 constantly prior to the time at which the shutter is pushed to photograph an optical image. And after the shutter is pushed, a memory control means 7 sends the sound data from a digital signal processor DSP3 to the memory 6 and simultaneously controls the addresses of the memory 6 so that the sound data from the memory 6 are sent to a sound memory 15. Thus, a natural sound recording is realized without an interruption.
