Abstract

To provide a display method capable of displaying the original power saving effect if a monitoring display of the power saving effect is not made when the monitoring display of the power saving effect is made. Provided is a display method including capturing an image in front of an image display surface included in a display apparatus that displays the image and detecting presence of a moving body positioned in front of the image display surface, deciding a power saving amount of the display apparatus including the power saving amount of the image display surface by using an analysis result of the presence or absence of a human face and a detection result of the moving body in the captured image, and deriving and displaying the actual power saving amount when no display is made on the image display surface on the image display surface when information about the power saving amount is displayed on the image display surface. Accordingly, when a monitoring display of a power saving effect is made, an original power saving effect if no monitoring display of the power saving effect is made can be displayed.

Claims

1. A display method, comprising:

capturing an image in front of an image display surface of a display apparatus that displays the image and detecting presence of a moving body positioned in front of the image display surface;

deciding a power saving amount of the display apparatus including the power saving amount of the image display surface by using an analysis result of the presence or absence of a human face and a detection result of the moving body in the captured image; and

deriving the actual power saving amount when no display is made on the image display surface and displaying the actual power saving amount as the power saving amount on the image display surface when information about the power saving amount is displayed on the image display surface.

2. The display method according to claim 1,

wherein when the information about the power saving amount is displayed on the image display surface, power consumption associated with a display thereof is taken into account before the display.

3. The display method according to claim 1,

wherein when the information about the power saving amount is displayed on the image display surface, the captured image is also displayed together.

4. The display method according to claim 3,

wherein when the captured image is displayed on the image display surface as the information about the power saving amount, the image is displayed after a predetermined time passes after the image being captured.

5. The display method according to claim 1,

wherein when the information about the power saving amount is displayed on the image display surface, the information about the power saving amount is displayed in a partial region of the image display surface.

6. The display method according to claim 5,

wherein when the information about the power saving amount is displayed on the image display surface, a light source used for an image display of the image display surface is turned off in other regions than the partial region.

8. The display method according to claim 1,

wherein when the information about the power saving amount is displayed on the image display surface, the power saving amount is decided by limiting, among the faces contained in the captured image, to a specific face.

9. The display method according to claim 8,

wherein the specific face is a face appearing in front of others.

10. The display method according to claim 8,

wherein the specific face is a face of a person specified in advance.

11. The display method according to claim 8,

wherein if a face considered to be positioned away by a predetermined distance or more is judged to be present based on the analysis result of the presence or absence of the human face and the detection result of the moving body in the captured image, the face is excluded from a decision target of the power saving amount.

7. The display method according to claim I,

wherein the information about the power saving amount is displayed as a graph chronologically representing a power consumption ratio together with a numeric value.

12. A display apparatus, comprising:

an imaging unit that captures an image in front of an image display surface of a display apparatus that displays the image;

a moving body detection unit that detects presence of a moving body positioned in front of the image display surface;

a power saving amount decision unit that decides a power saving amount of the whole apparatus including the power saving amount of the image display surface by using the captured image of the imaging unit and a detection result of the moving body of the moving body detection unit; and

a power saving amount display unit that derives the actual power saving amount when no display is made and displays the actual power saving amount as the power saving amount when information about the power saving amount and the captured image is displayed on the image display surface.
