<P>PROBLEM TO BE SOLVED: To provide a recording device capable of really feeling a change of directivity of a microphone in accordance with a change in focal distance in a lens interchangeable recording device. <P>SOLUTION: A lens interchangeable recording device capable of exchanging an imaging optical system includes: a built-in microphone 121 which collects sound; an interchangeable lens control unit 115 which acquires a focal distance in an operation range, and a present focal distance from an interchangeable lens 200; a CPU 109 which sets a variable amount of directivity to the focal distance in the operation range, determines a directivity parameter which controls the directivity of the collected sound based on a present position in the focal distance, and changes the directivity of the collected sound in accordance with the determined directivity parameter; and an audio control unit 119 which varies the directivity of the built-in microphone 121. <P>COPYRIGHT: (C)2013,JPO&INPIT |
