1. An apparatus comprising:
a first camera interface for receiving a first camera signal associated with an infrared camera view;
a second camera interface for receiving a second camera signal associated with a color camera view;
a metric calculation block configured to calculate at least one of an infrared brightness metric and a depth metric from the first camera signal, the infrared brightness metric indicating brightness of infrared light received at the infrared camera view; and
a selection block configured to generate a display control signal indicating selection of the infrared camera view for display in the presence of an obstruction in the infrared camera view, the infrared camera view selected for display if the infrared brightness metric is higher than a brightness threshold or if the depth metric is lower than a depth threshold.
