Abstract

A method for manipulation of image data for a display screen that can be operated in two operating modes, viz B1 for a free viewing mode and B2 for a restricted viewing mode, comprising: a) switching on the operating mode B2, b) monitoring the eye position of a viewer in a given angular range A, with a signal S being set if the eye position signifies that the viewer is looking at the screen, and being deleted if not looking at the screen, c) manipulating the image data with regard to image parameters, wherein the said manipulation i) is performed to the effect that the quality of the restricted viewing mode B2 is enhanced, ii) is dynamically implemented in a control unit of the display screen, and iii) is performed exclusively while the signal S remains set, and d) repeating steps b) and c) until operating mode B2 concluded.

Claims11

Dependent claims

A method for the manipulation of image data for a display screen that can be operated in at least two modes of operation, viz B1 for a free viewing mode, in which light is emitted by the display in an unrestricted angular range, and B2 for a restricted viewing mode, in which light is emitted by the display in a restricted angular range, comprising the following steps:

a) switching on the operating mode B2,
b) monitoring an eye position of a viewer in a given angular range A enclosing a vertical bisector of the display screen, and
setting a signal S when the eye position of the viewer signifies that the viewer is looking at the display screen, and
deleting the signal S, when the eye position of the viewer signifies that the viewer is not looking at the display screen,
c) manipulating the image data on the display screen as against an initial image data with regard to contrast, brightness, resolution, color space, cross fades and/or further image parameters, wherein the manipulation:
i. is performed to an effect that a deteriorated visual perceptibility of the image data is brought about, whereby a quality of the restricted viewing mode B2 is enhanced,
ii. is implemented dynamically in a control unit of the display screen, and
iii. is performed exclusively during a period in which the signal S is set,
d) repeating steps b) and c) until an abort condition is reached.
