Display method and display apparatus

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.

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.
