<P>PROBLEM TO BE SOLVED: To provide a sound collecting device, etc. which can obtain low-noise sound signals which have had mechanical sounds removed. <P>SOLUTION: A mechanical sound acquisition condition determination unit 102, when a predetermined time of day comes, determines whether a condition for collecting mechanical sounds is satisfied. When the condition is found to be satisfied, a mechanical sound acquisition processing unit 103 drives an AF drive unit 171 for a certain time to collect mechanical sounds with a microphone 15. A mechanical sound removal filter generation unit 104 generates a mechanical sound removal filter based on the collected mechanical sound, and a mechanical sound removal filter storage unit 105 stores the generated mechanical sound removal filter in a storage unit 12. A mechanical sound removal processing unit 106, when photographs of moving pictures are taken using an AF function, removes mechanical sounds from the sound signal collected with the microphone 15 by using the mechanical sound removal filter stored in the storage unit 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
