1. An apparatus comprising:
- a microphone array to sense an audio source;
an audio processor responsive to the microphone array to determine a direction of the audio source in relation to a frame of reference, the direction comprising an azimuth angle and an altitude angle;
a wide-angle digital camera system; and
an image processor responsive to the audio processor and the wide-angle digital camera system, the image processor to process at least one wide-angle image from the wide-angle digital camera system to generate at least one perspective corrected image in the direction of the audio source.

Abstract
A microphone array (20) senses an audio source (22). An audio processor (34) is responsive to the microphone array (20) to determine a direction (24) of the audio source (22) in relation to a frame of reference (32). The direction (24) comprises an azimuth angle (26) and an altitude angle (30). A wide-angle digital camera system (40) captures at least one wide-angle image. An image processor (44) is responsive to the audio processor (34) to process the at least one wide-angle image to generate at least one perspective corrected image (46) in the direction (24) of the audio source (22).
