发明名称 SOUND RECORDING DEVICE AND IMAGING DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a sound recording device and an imaging device which even when a sound abruptly increasing in sound volume is recorded, avoids reduction in gain (sound volume) in the middle of the sound. <P>SOLUTION: A sound recording device 110 comprises: a photometry circuit 114 which photometrically measures incident light and outputs a photometric signal corresponding to the result of the photometry; a microphone 111 which collects sound and outputs a sound signal corresponding to the sound; an amplifier 112 which amplifies the sound signal; an AGC 116 and a CPU 115 which set a gain in amplifying the sound signal by the amplifier 112, on the basis of the photometric signal; and the CPU 115 for recording the amplified sound signal. <P>COPYRIGHT: (C)2012,JPO&INPIT
