Abstract
The invention relates to a system for pre-adjusting the video image adjustment parameters of a flat screen device for displaying images, consisting of a screen and electronic control circuits which transmit video signals to it and a reticle generator. According to the present invention, the device further includes acquisition means for acquiring the video signals, means for calculating values of the adjustment parameters and adjustment means for storing the values of the adjustment parameters in the electronic control circuits.
Claims23
A system for pre-adjusting video image adjustment parameters of a flat screen device for displaying images, comprising:
- a screen;
- electronic control circuits which transmit video signals to the screen;
- a reticle generator, having acquisition means for acquiring the video signals;
- means for calculating values of the adjustment parameters;
- and
- adjustment means for storing the values of the adjustment parameters in the electronic control circuits,
- wherein the calculation means comprises a supervisor designed to repeat the calculations so long as the values of the adjustment parameters are within a predetermined range,
- wherein the electronic control circuits comprise a circuit for rendition of the adjustment parameters, which is designed to digitally store values of the calculated adjustment parameters, and
- wherein the adjustment means comprises a simulator of the circuit for rendition.
