Display device and control method

A display device, comprising:

• a sensor configured to detect whether or not a moving body is present in a predetermined range in an image display direction and
• circuitry configured to
• capture a moving image in a predetermined range in the image display direction,
• analyze the moving image to detect whether or not a face is present, and
• control power consumption with different patterns according to a plurality of modes that are set by determining whether or not the face is present and whether or not the moving body is present,
• wherein the circuitry does not start control of power consumption until the face or the moving body is first detected after power is turned on.

A control method, comprising:

• capturing, using a first sensor, a moving image in a predetermined range in an image display direction;
• detecting, in a second sensor and separately from captured moving images, whether or not a moving body is present in the predetermined range in the image display direction;
• detecting, in the second sensor, a distance between the moving body and the second sensor;
• analyzing the captured moving image to detect whether or not a face is present;
• and
• controlling power consumption with different patterns according to a plurality of modes based on whether or not the face is present and a detection result from the second sensor indicating whether or not the moving body is present and the distance from the moving body to the second sensor,
• wherein the control of power consumption does not start until the face or the moving body is first detected after power is turned on.
