METHOD AND DEVICE FOR DISPLAYING IMAGES
In one embodiment, the method for displaying images on an image display of a display unit includes detecting a plurality of reference points within the face of at least one person looking at the image display. The detection is performed by use of a detecting unit rigidly coupled to the display unit. The method further includes determining at least one movement component of a relative movement of the display unit with respect to the reference points, generating data of movement compensated images for an at least partial compensation of the movement component with respect to the reference points, and imaging the movement compensated images on the image display.
1 . A method for displaying images on an image display of a display unit, the method comprising the steps:
detecting a plurality of reference points within the face of at least one person looking at the image display, wherein the detection is performed by use of a detecting unit rigidly coupled to the display unit;
determining at least one movement component of a relative movement of the display unit with respect to the reference points;
generating data of movement compensated images for an at least partial compensation of the movement component with respect to the reference points; and
imaging the movement compensated images on the image display.
2 . The method according to claim 1 , wherein the movement component is a movement component in a direction within a plane parallel to the screen plane of the image display.
3 . The method according to claim 1 , wherein the movement component or at least one of the movement components is a periodically changing movement component.
4 . The method according to claim 3 , wherein the imaging of the movement compensated images at least compensates a fundamental frequency portion of the periodically changing movement component.
5 . The method according to claim 1 , wherein the movement component or at least one of the movement components is a sudden relative dislocation between the display device and the user.
6 . The method according to claim 1 . wherein a periodic or non-periodic movement perpendicular to the screen plane is detected by a reduced distance between the detected reference points.
7 . The method according to claim 1 , wherein the detecting unit comprises at least one camera.
8 . The method according to claim 1 , wherein an algorithm for face detection is used for detecting the reference points of the face.
9 . The method according to claim 1 , wherein each movement compensated image is composed of the effective image content framed by a background image portion when imaged on the image display.
10 . The method according to claim 9 , wherein each effective image content of the movement compensated images uses a fraction of 80% or less than 80% of the area of the total visible image display content.
11 . The method according to claim 1 . wherein the relative movement is a mean relative movement, when the reference points of a plurality of persons are detected.
12 . A computer program product comprising a computer usable medium including computer usable program code, wherein the computer usable program code is adapted to execute the method of claim 1 .
13 . A device, especially a device for performing the method according to claim 1 , comprising:
a display unit with an image display for displaying images,
a detecting unit suitable for detecting a plurality of reference points within the face of at least one person looking at the image display and
a processing unit connected to the display unit as well as the detecting unit by signal connection,
wherein the detecting unit is rigidly coupled to the display unit,
characterized in that the processing unit is arranged for determining at least one movement component of a relative movement of the display unit with respect to the detected reference points and for generating data of movement compensated images for an at least partial compensation of the movement component with respect to the reference points.
14 . The device according to claim 13 , wherein the processing unit is arranged for generating data of movement compensated images for an at least partial compensation of the movement component with respect to the reference points.
15 . The device according to claim 13 , wherein the device is a handheld device or a laptop device.
