Imaging device superimposing wideband noise on output sound signal

摘要

A sound pickup device includes a detector configured to detect attachment of an external apparatus, a sound pickup unit configured to pick up a sound and output a sound signal, and a noise processor configured to, in response to the detection of attachment of an external appliance, add a noise signal to the sound signal output from the sound pickup unit and output the sound signal including the noise signal added thereto.

主权项

1. An imaging device to which an interchangeable lens is mountable, comprising:
a detector configured to detect attachment of the interchangeable lens; an imaging unit configured to capture a subject image incident through the interchangeable lens and output image data; a sound pickup unit configured to pick up a sound and output a sound signal; a noise processor configured to, in response to detection of attachment of the interchangeable lens by the detector, superimpose a wideband noise signal to the sound signal output from the sound pickup unit and output the sound signal including the wideband noise signal superimposed thereto; and a memory device configured to store a masking setting table which associates characteristic information indicating characteristic of the interchangeable lens with a wideband noise; wherein the detector obtains the characteristic information from the interchangeable lens; and the noise processor selects a wideband noise to be superimposed on the output sound signal by referring to the masking setting table based on the characteristic information obtained from the interchangeable lens.
