Abstract

A display device is described and includes a fixing unit, through which the display device is capable of being worn on a head of a user; a processing unit configured to obtain a first image to be displayed; an image transmission unit configured to transmit the first image to a display unit, which is configured to display the first image obtained by the processing unit; a connection unit configured to connect the fixing unit and at least a first portion of the display unit, wherein the connection unit at least has a first state, in which at least the first portion is located in the user'"'"'s visual region and faces the user; an image capturing unit configured to capture a second image; and the processing unit being further configured to generate the first image based on the second image.

Claims

1. A display device, comprising:

a fixing unit, through which the display device is capable of being worn on a head of a user;

a processing unit configured to obtain a first image to be displayed;

an image transmission unit configured to transmit the first image to a display unit;

the display unit configured to display the first image obtained by the processing unit;

a connection unit configured to connect the fixing unit and at least a first portion of the display unit, wherein the connection unit at least has a first state and a second state, such that in the first state at least the first portion is located in a user'"'"'s visual region and faces the user and at least the first portion of the display unit is movable away from the user'"'"'s visual region;

an image capturing unit configured to capture a second image and comprising a rotator configured to rotate around an axis of itself;

a reflector configured to reflect surroundings of the display device to an image collector, wherein

the reflector is connected to the rotator such that the reflector is capable of rotating with respect to the axis of the rotator;

the image collector is fixed on the fixing unit and configured to receive light reflected from the reflector and to capture the second image; and

an adjusting unit configured to adjust the rotator to adjust a capture area of the image capturing unit according to a position of an object to be captured by the image capturing unit; and

the processing unit being further configured to generate the first image based on the second image; and

a pop-up unit configured to connect the fixing unit and the image capturing unit, having a pop-up state and a pack-up state, wherein, in the pop-up state, the image capturing unit is located outside the fixing unit, and the image capturing unit is on and capturing images; and

in the pack-up state, the image capturing unit is located inside the fixing unit, and

the image capturing unit is off.

2. The display device according to claim 1, wherein the image capturing unit is disposed outside the fixing unit.

3. The display device according to claim 1, wherein

the connection unit includes a first sub-connection unit and a second sub-connection unit;

the display unit includes a first sub-display unit and a second sub-display unit,

wherein the first sub-connection unit connects a first end of the fixing unit and the first sub-display unit, and the second sub-connection unit connects a second end of the fixing unit and the second sub-display unit;

the first portion includes a first sub-portion located in the first sub-display unit and a second sub-portion located in the second sub-display unit.

4. The display device according to claim 3, wherein

the image capturing unit includes a first sub-image capturing unit and a second sub-image capturing unit;

the first sub-image capturing unit is disposed corresponding to the first sub-portion, and the second sub-image capturing unit is disposed corresponding to the second sub-portion.

5. The display device according to claim 3, wherein the image capturing unit is located between the first sub-portion and the second sub-portion.

6. The display device according to claim 1, further comprising:

a capture object positioning unit configured to determine the position of the object to be captured,

the adjusting unit automatically adjusts the capture area of the image capturing unit according to the position of the object to be captured that is determined by the capture object positioning unit.
