US 2006/0132624 A1 · Electronic camera with noise reduction unit

Abstract

An image and sound recording operation is performed, and image data is successively recorded on a memory (S201). It is judged whether or not a current waveform has reached a threshold value to determine if the current waveform becomes ON (S202). When the current waveform is not ON, sound data detected by a microphone is stored in the memory at step S205 without performing processes at steps S203 and S204. When the current waveform is ON, and a zoom motor starts its rotation, zoom sound data previously stored in the memory is read out therefrom at step S203. Further, a subtracting process is performed at step S204 to subtracting a zoom sound from sound data of the surroundings obtained by the microphone and an audio signal processing circuit, and the resultant data is stored in the memory as sound data to be stored at step S205.

Dependent claims

An electronic camera comprising:

an image photographing unit for photographing a moving image;
a detecting unit for detecting sounds from the surroundings while the moving image is being photographed by the image photographing unit;
a recording unit for recording the moving image photographed by the image photographing unit and the sounds detected by the detecting unit;
an operating unit driven by a current;
a noise reducing unit for performing a noise reducing operation to reduce noises produced by operation of the operating unit;
and
a control unit for judging, on the basis of a current waveform of the current for driving the operating unit, whether or not the noise reducing unit should perform the noise reducing operation.
