1. A method comprising:
- processing received image data and/or received depth data to track an object moving in a monitored scene space;
determining a bearing of the moving object in the monitored scene space;
filtering outputs from a plurality of spatially diverse microphones in dependence upon the bearing of the moving object in the monitored scene space to produce a combined audio output signal, wherein the combined audio output signal has directional gain in a target direction;
defining at least a first portion of the monitored scene space and a second portion of the monitored scene space separated by at least one virtual boundary;
detecting movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary; and
in dependence upon detecting movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary, changing the target direction from a first direction being one of one or more target directions associated with the first portion of the monitored scene space to a second direction being one of the one or more target directions associated with the second portion of the monitored scene space, wherein the second direction is different from the first direction.

Abstract
A method comprising: processing received image data and/or received depth data to track an object moving in a monitored scene space; determining a bearing of the tracked moving object in the monitored scene space; and adaptively filtering outputs from a plurality of spatially diverse microphones in dependence upon the bearing of the tracked moving object in the monitored scene space to produce a combined audio signal.

11. An apparatus comprising at least one processor and at least one memory, the memory comprising machine-readable instructions, that when executed cause the apparatus to:
-
process received image data and/or received depth data to track an object moving in a monitored scene space; determine a bearing of the moving object in the monitored scene space; filter outputs from a plurality of spatially diverse microphones in dependence upon the bearing of the moving object in the monitored scene space to produce a combined audio output signal, wherein the combined audio output signal has directional gain in a target direction; define at least a first portion of the monitored scene space and a second portion of the monitored scene space separated by at least one virtual boundary; detect movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary; and in dependence upon detecting movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary, change the target direction from a first direction being one of one or more target directions associated with the first portion of the monitored scene space to a second direction being one of the one or more target directions associated with the second portion of the monitored scene space, wherein the second direction is different from the first direction. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. At least one non-transitory computer readable medium comprising instructions that, when executed, perform:
-
process received image data and/or received depth data to track an object moving in a monitored scene space; determine a bearing of the moving object in the monitored scene space; filter outputs from a plurality of spatially diverse microphones in dependence upon the bearing of the moving object in the monitored scene space to produce a combined audio output signal, wherein the combined audio output signal has directional gain in a target direction; define at least a first portion of the monitored scene space and a second portion of the monitored scene space separated by at least one virtual boundary; detect movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary; and in dependence upon detecting movement of the moving object from the first portion of the monitored scene space to the second portion of the monitored scene space across the at least one virtual boundary, change the target direction from a first direction being one of one or more target directions associated with the first portion of the monitored scene space to a second direction being one of the one or more target directions associated with the second portion of the monitored scene space, wherein the second direction is different from the first direction.
