An example information processing apparatus including an infrared light emitter capable of emitting infrared light and a camera capable of at least taking an infrared light image is provided. In the information processing apparatus, first, an image taken by use of the camera is obtained. A face detection process based on the image is repeatedly executed. Then, based on a result of the face detection process, emission of the infrared light is stopped and emission of the infrared light is resumed after a lapse of a predetermined time period.
