In automatic photographic or electronic camera apparatus, sounds from a person are preferentially received or identified to provide an audio signal, used to produce a saliency signal (indicative of the person's response to circumstances) to control the camera or an image signal produced therefrom. The sounds are detected by a sound conduction microphone, e.g. on the head or throat of the person, or by voice identification circuitry used with a less specific microphone not necessarily mounted on the person, who may or may not be wearing the camera. Control can be in real time, or the sound or saliency signal can be recorded with an image signal for subsequent control of the latter. The audio signal is categorised by waveform analysis, e.g. for the recognition of sounds, such as speech or non-speech vocal sounds, and/or non-vocal sounds; signal amplitude may also be taken into account.
