1. A display device, comprising:
- a circuit connected to a first sensor to receive a moving image captured by the first sensor in a predetermined range and connected to a second sensor to detect whether a moving body is present in the image display direction, the circuitry being configured toanalyze the moving image to detect whether or not a face is present, andafter power is turned on, start to control power consumption with different patterns according to a plurality of modes when the face is present in the moving image or the moving body is present in the display direction,wherein the different patterns include a first pattern in which power consumption is ramped down in at least two decreasing stages and ramped up in at least two increasing stages based on detection of the face and the moving body,when power consumption is ramped down, a first of the at least two decreasing stages is reached based on lack of detection of the face and a second of the at least two decreasing stages is reached based on lack of detection of the moving body, andwhen power consumption is ramped up, a first of the at least two increasing stages is reached based on detection of the moving body, the first of the at least to increasing stages being reached by increasing brightness, the power consumption remaining at the first of the at least two stages until detection of the face, the power consumption being increased from the first state to full power upon detection of the face.

Abstract
Provided is a display device including an imaging unit that captures a moving image in a predetermined range in an image display direction, a moving body detection unit that detects whether or not a moving body is present in a predetermined range in the image display direction, an image analysis unit that analyzes the moving image captured by the imaging unit to detect whether or not a face is present, and a power control unit that controls power consumption with different patterns according to a plurality of modes that are set by combining whether or not the face detected by the image analysis unit is present and whether or not the moving body detected by the detection unit is present.

13. A control method, comprising:
-
analyzing a moving image captured in a predetermined range in an image display direction by a first sensor to detect whether or not a face is present; detecting, via 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; and after power is turned on, starting control of power consumption with different patterns according to a plurality of modes when the face is present in the moving image or when the moving body is present in the display direction, wherein the different patterns include a first pattern in which power consumption is ramped down in at least two decreasing stages and ramped up in at least two increasing stages based on detection of the face and the moving body, when power consumption is ramped down, a first of the at least two decreasing stages is reached based on lack of detection of the face and a second of the at least two decreasing stages is reached based on lack of detection of the moving body, and when power consumption is ramped up, a first of the at least two increasing stages is reached based on detection of the moving body, the first of the at least two increasing stages being reached by increasing brightness, the power consumption remaining at the first of the at least two stages until detection of the face, the power consumption being increased from the first state to full power upon detection of the face. - View Dependent Claims (14, 15)
