Abstract

A display apparatus according to the present invention, includes: a display panel; a display optical system for looking at the display panel; an image sensor for capturing an eye of an user looking at the display panel, the image sensor having a rectangular imaging plane; and an imaging optical system for forming an optical image of the eye on the imaging plane, wherein the imaging optical system has an optical axis that is nonparallel to an optical axis of the display optical system, and a projected line of the optical axis of the display optical system on the imaging plane is substantially parallel to a long side of the imaging plane.

Claims (30)

1. A display apparatus comprising:

a display panel;

a lens configured to enable a user to see an image displayed on the display panel;

an image sensor for capturing an eye of the user looking at the display panel, the image sensor having a rectangular imaging plane; and

an imaging optical system for forming an optical image of the eye on the imaging plane, wherein

the imaging optical system has an optical axis that is nonparallel to an optical axis of the lens,

a projected line of the optical axis of the lens on the imaging plane is substantially parallel to a long side of the imaging plane,

the lens is a lens having a shape as obtained by removing a part of a peripheral portion of a circular shape from the circular shape in a view from the direction parallel to the optical axis of the lens, and

the imaging optical system is disposed such that at least part of the image sensor is included in a region as formed by removing the part of the peripheral portion in the view from the direction parallel to the optical axis of the lens.

2. The display apparatus according to claim 1 , wherein

the image sensor is disposed upward from below the optical axis of the lens in a case where the display apparatus is in a predetermined orientation.

3. The display apparatus according to claim 2 , wherein

the image sensor is disposed upward from below the display panel in a case where the display apparatus is in the predetermined orientation.

4. The display apparatus according to claim 3 , wherein

the display panel has a display surface that is rectangular with a long side substantially parallel to a left and right direction in a case where the display apparatus is in the predetermined orientation.

5. The display apparatus according to claim 4 , wherein

the display surface has a long side and a short side, and

an aspect ratio of a length of the long side to a length of the short side is substantially 4:3.

6. The display apparatus according to claim 1 , wherein

the lens has the shape as obtained by cutting off the part of the peripheral portion in the view from the direction parallel to the optical axis of the lens.

7. The display apparatus according to claim 6 , wherein

the lens has the shape as obtained by cutting off the part of the peripheral portion along a cut-off line including a straight portion substantially parallel to a side of a display surface of the display panel in the view from the direction parallel to the optical axis of the lens.

8. The display apparatus according to claim 1 , further comprising

a detector configured to detect a gaze of the user based on an image of the eye captured by the image sensor.

9. A finder apparatus comprising:

the display apparatus according to claim 1 ; and

an eyepiece portion where the eye approach.

10. An imaging apparatus comprising:

a second image sensor for capturing an object; and

the display apparatus according to claim 1 capable of displaying an image of the object captured by the second image sensor.
