| 摘要 |
A sensing apparatus having a sensing functionality controller and a method of detecting the sensing apparatus is disclosed. A signal generation unit embedded in the sensing apparatus operates in conjunction with the sensing functionality controller to support the sensing functionality of the sensing unit. The signal generation unit generates one or more sensing functionality support signals used to enhance content obtained by the sensing unit, (e.g., a flash for illuminating a sensed target such that content obtained by the sensing unit is not too dark, or a sound or light-based auto focus signal to make sure that the content is not out of focus). When the sensing functionality controller is activated, the same signal generation unit generates a detectable warning signal, (e.g., sound, light, radio wave), which indicates that the sensing functionality controller has been activated and/or the sensing unit is sensing.
