| 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. |

| Claim: | 1. A display method, comprising: capturing a first image in front of an image display surface of a display apparatus that displays a second image and detecting presence of a moving body positioned in front of the image display surface; deciding, by circuitry of the display apparatus, power saving control information for the display apparatus including power saving control information for the image display surface based on an analysis result of the presence or absence of a human face and a detection result of the moving body in the captured first image; deriving, by the circuitry, actual power saving amounts over a period of time, at least one of the actual power saving amounts being derived based on subtracting a power consumption associated with displayed power saving information from a total power consumption of the image display surface at a time the power saving information is being displayed; and causing, by the circuitry, display of the power saving information including the at least one of the actual power saving amounts on the image display surface, wherein the at least one of the actual power saving amounts is displayed in a partial region of the image display surface, and a light source used for an image display of the image display surface is turned off in regions other than the partial region. |
| Claim: | 2. The display method according to claim 1 , wherein the captured first image is also displayed concurrently with the at least one of the actual power saving amounts. |
| Claim: | 3. The display method according to claim 2 , wherein the captured first image is displayed after a predetermined time passes after the first image is captured. |
| Claim: | 4. The display method according to claim 1 , wherein the at least one of the actual power saving amounts is displayed as a graph chronologically representing a power consumption ratio together with a numeric value corresponding to the at least one of the actual power saving amounts. |
| Claim: | 5. The display method according to claim 1 , wherein the power saving control information is decided by limiting, among faces contained in the captured first image, to a specific face. |
| Claim: | 6. The display method according to claim 5 , wherein the specific face is a face appearing in front of others. |
| Claim: | 7. The display method according to claim 5 , wherein the specific face is a face of a person specified in advance. |
| Claim: | 8. The display method according to claim 5 , wherein when 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 first image, the face is excluded from a decision target of the power saving control information. |
| Claim: | 9. The display method according to claim 1 , further comprising: determining the power consumption of the image display surface when the power saving information is displayed on the image display surface; and separately determining the power consumption associated with the display of only the power saving information. |
| Claim: | 10. A display apparatus, comprising: an imaging unit that captures a first image in front of an image display surface of the display apparatus that displays a second 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 power saving control information for the display apparatus including power saving control information for the image display surface based on the captured first 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 actual power saving amounts over a period of time, at least one of the actual power saving amounts being derived based on subtracting a power consumption associated with displayed power saving information from a total power consumption of the image display surface at a time the power saving information is being displayed, and causes display of the power saving information including the at least one of the actual power saving amounts on the image display surface, wherein the at least one of the actual power saving amounts is displayed in a partial region of the image display surface, and a light source used for an image display of the image display surface is turned off in regions other than the partial region. |
| Claim: | 11. A display apparatus, comprising: an imaging sensor configured to capture a first image in front of an image display surface of the display apparatus that displays a second image; a moving body sensor that detects presence of a moving body positioned in front of the image display surface; and circuitry configured to decide power saving control information for the display apparatus including power saving control information for the image display surface based on the captured first image of the imaging sensor and a detection result of the moving body of the moving body sensor, derive actual power saving amounts over a period of time, at least one of the actual power saving amounts being derived based on subtracting a power consumption associated with displayed power saving information from a total power consumption of the image display surface at a time the power saving information is being displayed, and cause display of the power saving information including the at least one of the actual power saving amounts on the image display surface, wherein the at least one of the actual power saving amounts is displayed in a partial region of the image display surface, and a light source used for an image display of the image display surface is turned off in regions other than the partial region. |
| Claim: | 12. The display apparatus according to claim 11 , wherein the captured first image is also displayed concurrently with the at least one of the actual power saving amounts. |
| Claim: | 13. The display apparatus according to claim 12 , wherein the captured first image is displayed after a predetermined time passes after the first image is captured. |
| Claim: | 14. The display apparatus according to claim 11 , wherein the at least one of the actual power saving amounts is displayed as a graph chronologically representing a power consumption ratio together with a numeric value corresponding to the at least one of the actual power saving amounts. |
| Claim: | 15. The display apparatus according to claim 11 , wherein the power saving control information is decided by limiting, among faces contained in the captured first image, to a specific face. |
| Claim: | 16. The display apparatus according to claim 15 wherein the specific face is a face appearing in front of others. |
