Display apparatus, display apparatus driving method, and electronic instrument

A display apparatus driving method, comprising:

• detecting a left eye of an observer and a right eye of the observer;
• generating virtual image information for each of a left-eye pixel and a right-eye pixel based on the detection of the left eye of the observer and the right eye of the observer, wherein
• the virtual image information is generated to present a virtual image in a first aspect ratio different from a second aspect ratio of a display surface of a display unit,
• for each of the left eye of the observer and the right eye of the observer, a first number of pixels of the virtual image in a horizontal direction is half a second number of pixels of the display unit and a third number of pixels of the virtual image in a vertical direction is equal to the second number of pixels of the display unit, and
• the display unit includes:
• a lens for a plurality of adjoining pixels including the left-eye pixel and the right-eye pixel;
• and
• an effective pixel region;
• and
• driving the left-eye pixel and the right-eye pixel based on the generated virtual image information such that the virtual image is presented at a presentation position different from a position of the display surface of the display unit, wherein
• the virtual image is presented in a same viewing direction as the display surface with respect to a position of the observer,
• the virtual image corresponds to a left-eye image and a right-eye image,
• the left-eye image corresponds to the left-eye pixel,
• the right-eye image corresponds to the right-eye pixel,
• a first image display range of the effective pixel region and a first non-image display region of the effective pixel region correspond to the left-eye image,
• a second image display range of the effective pixel region and a second non-image display region of the effective pixel region correspond to the right-eye image,
• the first non-image display region is at a right end side portion of the effective pixel region,
• the second non-image display region is at a left end side portion of the effective pixel region, and
• the first image display range and the second image display range are adjustable based on a viewing distance of the observer from the display unit.

An electronic instrument, comprising:

• a display apparatus that includes:
• a display unit including:
• a lens for a plurality of adjoining pixels including a left-eye pixel and a right-eye pixel;
• and
• an effective pixel region;
• and
• at least one processor configured to:
• detect a left eye of an observer and a right eye of the observer;
• generate virtual image information for each of the left-eye pixel and the right-eye pixel based on the detection of the left eye of the observer and the right eye of the observer, wherein
• the virtual image information is generated to present a virtual image in a first aspect ratio different from a second aspect ratio of a display surface of the display unit, and
• for each of the left eye of the observer and the right eye of the observer, a first number of pixels of the virtual image in a horizontal direction is half a second number of pixels of the display unit and a third number of pixels of the virtual image in a vertical direction is equal to the second number of pixels of the display unit;
• and
• drive the left-eye pixel and the right-eye pixel based on the generated virtual image information such that the virtual image is presented at a presentation position different from a position of the display surface of the display unit, wherein
• the virtual image is presented in a same viewing direction as the display surface with respect to a position of the observer,
• the virtual image corresponds to a left-eye image and a right-eye image,
• the left-eye image corresponds to the left-eye pixel,
• the right-eye image corresponds to the right-eye pixel,
• a first image display range of the effective pixel region and a first non-image display region of the effective pixel region correspond to the left-eye image,
• a second image display range of the effective pixel region and a second non-image display region of the effective pixel region correspond to the right-eye image,
• the first non-image display region is at a right end side portion of the effective pixel region,
• the second non-image display region is at a left end side portion of the effective pixel region, and
• the first image display range and the second image display range are adjustable based on a viewing distance of the observer from the display unit.
