Abstract
A process for color adjustment of a color monitor including a cathode-ray tube and a brightness adjustment module includes providing a nominal brightness signal downstream of a white level adjustment module for adjusting a white level and upstream of a black level adjustment module for adjusting a black level. The process also includes setting a voltage required to obtain a black color image, setting a voltage required to obtain a white color image, providing the nominal brightness signal upstream of the white level adjustment module, and setting the voltage required to obtain the black color image.
Claims34
A method for adjusting color of an image on a color monitor comprising a cathode-ray tube and a brightness adjustment module, the method comprising:
- providing a nominal brightness signal downstream of a white level adjustment module for adjusting a white level of the image and upstream of a black level adjustment module for adjusting a black level of the image;
- setting a voltage required to obtain a black color image;
- setting a voltage required to obtain a white color image;
- providing the nominal brightness signal upstream of the white level adjustment module;
- and
- setting the voltage required to obtain the black color image.
A method for adjusting color of an image on a color monitor comprising:
- adjusting a brightness of the image upstream of at least one white adjustment module for adjusting a white level of the image;
- setting a level required to obtain a black color image;
- setting a level required to obtain a white color image;
- and
- adjusting the brightness of the image downstream of the at least one white adjustment module.
A device for adjusting color of an image on a color monitor comprising:
- at least one black adjustment module for setting a level required to obtain a black color image;
- at least one white adjustment module for setting a level required to obtain a white color image;
- an upstream brightness adjustment module portion for adjusting the brightness of the image upstream of the at least one white adjustment module;
- and
- a downstream brightness adjustment module portion for adjusting the brightness of the image downstream of the at least one white adjustment module.
A device for adjusting color of an image on a color monitor comprising:
- at least one black adjustment module for setting a level required to obtain a black color image;
- at least one white adjustment module for setting a level required to obtain a white color image;
- and
- at least one brightness adjustment module for adjusting the brightness of the image upstream and downstream of the at least one white adjustment module.
A color monitor for displaying a color image comprising:
- a cathode-ray tube for generating the color image;
- at least one black adjustment module for setting a level required to obtain a black color image;
- at least one white adjustment module for setting a level required to obtain a white color image;
- and
- at least one brightness adjustment module for adjusting the brightness of the image upstream and downstream of the at least one white adjustment module.
