The display screen is provided with a display surface facing a user. The first image capturing element is disposed on a side of the display surface of the display screen, and is configured to trace an eye position of the user. The second image capturing element is disposed on a side of the display screen facing away from the display surface, and is configured to capture a scene image of a scene located in a line-of-sight of the user and blocked by the display screen. The control module is adapted to display at least a portion of the scene image on the display screen according to the eye position of the user. ## Claims ### Claim 1 A display apparatus, comprising: a display screen, provided with a display surface facing a user; a first image capturing element, disposed on a side of the display surface of the display screen, and configured to track an eye position of the user; a second image capturing element, disposed on a side of the display screen facing away from the display surface, and configured to capture a scene image of a scene located in a line-of-sight of the user and blocked by the display screen; and a control module, adapted to display at least a portion of the scene image on the display screen according to the eye position of the user. ### Claim 2 (depends on 1) The display apparatus according to claim 1, wherein the control module comprises: an eye position calculation unit, adapted to calculate the eye position of the user according to an image of the user captured by the first image capturing element. ### Claim 3 (depends on 1) The display apparatus according to claim 1, wherein the control module comprises: an image processing unit, adapted to adjust the scene image according to a relative relationship between the eye position of the user and a shooting position of the second image capturing element. ### Claim 4 (depends on 3) The display apparatus according to claim 3, wherein a distance between the eye position of the user and the display screen in a normal direction of the display surface is x1, and a distance between the eye position of the user and the scene in the normal direction of the display surface is x2, a distance between the eye position and the shooting position of the second image capturing element in a direction parallel to the display surface is h, an angle between a virtual line between the eye position and any position of the scene and the normal direction of the display surface is α, an angle between a virtual line between the shooting position of the second image capturing element and the any position of the scene and the normal direction of the display surface is β, and α and β satisfy the following relational expression: β = tan - 1 [ 1 x 2 - ⁢ x 1 ⁢ ( x 2 ⁢ tan ⁡ ( α ) - h ) ] . ### Claim 5 (depends on 1) The display apparatus according to claim 1, wherein the control module comprises: a camera field of view calculation unit, configured to obtain a field of view range of the second image capturing element; and an image processing unit, adapted to capture a portion of the scene image captured by the second image capturing element within a portion of the field of view range according to a relative relationship between the eye position of the user and a display edge of the display screen. ### Claim 6 (depends on 5) The display apparatus according to claim 5, wherein the image processing unit is further adapted to adjust the portion of the scene image according to a relative relationship between the eye position of the user and a shooting position of the second image capturing element. ### Claim 7 (depends on 6) A display apparatus according to claim 6, wherein a distance between the eye position of the user and the display screen in a normal direction of the display surface is x1, and a distance between the eye position of the user and the scene in the normal direction of the display surface is x2, a distance between the eye position and the shooting position of the second image capturing element in a direction parallel to the display surface is h, an angle between a virtual line between the eye position and any position of the scene and the normal direction of the display surface is α, an angle between a virtual line between the shooting position of the second image capturing element and the any position of the scene and the normal direction of the display surface is β, and α and β satisfy the following relational expression: β = tan - 1 [ 1 x 2 - ⁢ x 1 ⁢ ( x 2 ⁢ tan ⁡ ( α ) - h ) ] . ### Claim 8 (depends on 1) A display apparatus according to claim 1, wherein the display surface of the display screen is provided with a first display area and a second display area, the control module is adapted to display a portion of the scene image and an information image in the first display area and the second display area respectively, the information image is different from the scene image, and a virtual line between a portion of the scene corresponding to the portion of the scene image and the eye position of the user passes through the first display area of the display screen. ### Claim 9 (depends on 8) The display apparatus according to claim 8, wherein the control module comprises: a display area dividing unit, adapted to position the first display area and the second display area on the display screen; and an image processing unit, adapted to correspondingly capture a part of the scene image captured by the second image capturing element according to a position of the first display area on the display screen. ### Claim 10 (depends on 1) The display apparatus according to claim 1, wherein the display screen is a non-transparent display panel. ### Claim 11 (depends on 1) The display apparatus according to claim 1 further comprising: a projection element, adapted to project the at least a portion of the scene image on the display surface of the display screen.
