Patent ID: 8478121

Claim:
A camera, comprising: an image sensor converting light rays projected thereon to digital image signals; a storing module storing the digital image signals; an infrared shutter module comprising an infrared emitter and an infrared receiver adjacent to the infrared emitter, the infrared shutter module being configured to output a triggering signal upon a condition that infrared rays emitted from the infrared emitter are received by the infrared received; a controlling module electrically connected with the image sensor, the storing module and the infrared shutter module, the controlling module storing the digital image signals in the storing module when receiving the triggering signal; a switching module electrically connected between the infrared shutter module and the controlling module, when the switching module is switched on, and the controlling module connects to the infrared shutter module; when the switching module is switched off, and the controlling module disconnects to the infrared shutter module.
