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).
