Abstract
A digital camera includes an optical assembly and image sensor for capturing still and/or video images and displaying the images on a screen. The camera includes three or more spaced apart microphones aligned with the optical assembly for capturing audio during image capture. At least two pairs of microphones are spaced apart along orthogonal directional axes for capturing left-right stereo sound in any camera orientation.

(canceled).
The digital camera of claim 23, wherein said at least three spaced-apart microphones include a first pair that is spaced apart along a first directional axis and a second pair that is spaced apart along a second directional axis orthogonal to the first axis.
A digital camera, comprising:
- a digital camera housing;
- a first image sensor coupled within the housing;
- an optical assembly including one or more lenses contained within a lens housing for forming images on the first image sensor;
- a display screen coupled to the housing;
- and
- at least three spaced-apart microphones aligned with the optical assembly for capturing audio during image capture, wherein at least one microphone is spaced apart from at least one other microphone along two directional axes for capturing stereo audio in at least two camera orientations;
- wherein said at least three spaced-apart microphones include a first pair that is spaced apart along a first directional axis and a second pair that is spaced apart along a second directional axis orthogonal to the first axis, and
- wherein the first pair includes a first microphone and a second microphone spaced apart along the first axis, and the second pair includes the first microphone and a third microphone spaced apart along the second axis, and
- wherein the first and second pairs are each spaced apart by at least half of full camera size along the first axis and second axis, respectively, and
- wherein the digital camera comprises at least one rear-facing microphone,
- wherein a polarity of the rear facing microphone is adjustable from negative to cancel rear sound to positive to capture rear sound.
