Abstract

Mirror device (1) comprises a display device (3) and a camera (2) to record an image. The device comprises means for determining (4, 41) the position of a body part. Said means put out a signal (S) indicative of the position of the body part with respect to the a display screen of a display device (3) for a viewer in front of the mirror device. In dependence of this signal (S) the view point from which the to be displayed image is recorded is changed.

Claims

1. Mirror device (1) comprising a display device (3) with a display screen

at least one image recording device (2) to record an image

a means (4, 41) to determine a position of a body part with respect to the display screen of the display device (3), said means outputting a indication signal (S) to indicate the position of the body part of a viewer in front of the display screen

a means to change (7) the view point from which the image is recorded in dependence on said indication signal (S)

a means to display the recorded image on the display screen of the display device (3).

2. Mirror device as claimed in claim 1 wherein the body part is a face or head part or a torso.

3. Mirror device as claimed in claim 1, wherein the means to change the view point are arranged to increase, with respect to a reflected image, the angle of rotation (β

) of the displayed image.

4. Mirror device as claimed in claim 1 wherein the means to change the point of view are arranged to change the magnification (M) of the displayed image, with respect to a reflected image.

5. Mirror device as claimed in claim 1, wherein the mirror device comprises a movable camera and means (8) to move the movable camera, wherein the position of the movable camera is determined by the position of the body part with respect to the display screen.

6. Mirror device as claimed in claim 1, wherein the mirror device comprises a number of cameras.

7. Mirror device as claimed in claim 6 wherein an image is synthesized from the images taken by the cameras, the point of view of the synthesized image being dependent on the signal (S).

8. Mirror device as claimed in claim 1, wherein the mirror device comprises a means to determine a position (41) separate from the image recording means.

9. Mirror device as claimed in claim 1, wherein the mirror device comprises a layer in front of the display screen that is switchable between a first reflective state and a second transparent state.

10. Mirror device as claimed in claim 1, wherein the mirror device is provided with a reflective, semi-transparent layer in front of the display screen and the means for displaying the recorded image are arranged such that for a first range of positions, no image is displayed, whereby the reflective layer acts as a mirror, and for a second range of positions, the recorded image is displayed.

11. Mirror device as claimed in claim 10, wherein the reflective semi-transparent layer is switchable between a first state with a relatively high reflectivity and relatively low transparency, and a second state with a relatively low reflectivity and high transparency.

12. Mirror device as claimed in claim 9, wherein the device comprises means (D2) for gradually switching the layer between the first and second state.

13. Mirror device as claimed in claim 1, wherein the mirror device comprises means (D3) for rotation the recording device (2).

14. Device comprises a frame with a recording device to record an image for a display device, a means 4 to determine a position of a body part with respect to the frame, said means outputting a indication signal (S) to indicate the position of the body part of a viewer with respect to the frame, a means to change (7) the view point from which the image is recorded in dependence on said indication signal (S), a means to generate an image signal (I) of the recorded image for display on a display screen of a display device.

15. Device as claimed in claim 14, wherein the frame comprises a semi-reflective layer.
