Abstract:
A mobile phone which is an example of electronic equipment includes an infrared camera and an infrared LED. The infrared camera is arranged above a display and the infrared LED is arranged below the display. A user, by an eye-controlled input, designates a button image or a predetermined region on a screen. When a line of sight is to be detected, an infrared ray (infrared light) emitted from the infrared LED arranged below the display is irradiated to a lower portion of a pupil. Accordingly, even in a state that the user slightly closes his/her eyelid, the pupil and a reflected light of the infrared light can be imaged.
