Method and device for processing color signals

The invention provides a method and a device for processing color signals. The method for processing color signals is used for the device for processing color signals so as to regulate a tricolor signal generating module of a display. The method comprises the following steps: inputting test signals into the display; retrieving an original color signal of the display; judging whether the original color signal is in an ideal color signal predetermined range or not; if the original color signal is not in an ideal color signal predetermined range, fixing one color signal generating module in the tricolor signal generating module and regulating another two color signal generating modules of the tricolor signal generating module.

Method and device for adjusting color temperature coordinate value measured by color analyzer

The invention relates to a method and a device for adjusting a color temperature coordinate value measured by a color analyzer. The device comprises a main control module. The method comprises the following steps: displaying a testing image on a standard display; receiving a color temperature coordinate value measured by the color analyzer to the standard display; obtaining a preset standard colortemperature coordinate value and comparing the preset color temperature coordinate value with the measured color temperature coordinate value so as to obtain a color temperature deviation value; andadjusting the color temperature coordinate value measured by the color analyzer through the color temperature deviation value.

Method and device for establishing grayscale - brightness curve of display quickly

A method of swiftly creating a gray scale value-illumination curve of a displayer ensures that a color displayer displays a detecting image which includes a plurality of block images, and every block image corresponds to different gray scale values. By utilizing an optical sensor and a color analyzer, the luminance value corresponding to every block image is obtained, and the gray scale value-illumination curve can be obtained in accordance with a plurality of gray scale value and corresponding luminance value.

Displayer and method for dynamically displaying OSD (on screen display) menu

The invention discloses a displayer and a method for dynamically displaying an OSD (on screen display) menu. The displayer is characterized in that an OSD animation firmware and an original OSD menu picture are stored in a first memory of the displayer; and after receiving a command for opening an OSD menu, a microcontroller of the displayer reads and then executes the OSD animation firmware so as to sequentially generate first to (N-1)th OSD menu pictures (shielded pictures with gradually decreased shielded areas are superimposed on each original OSD menu picture so as to form the OSD menu pictures that the (N-1) parts are shielded), and sequentially and continuously store the OSD menu pictures of which the (N-1) parts are shielded and a Nth original OSD menu picture in a second memory temporarily, so that an image output unit of the displayer is sequentially and continuously read and output to a display part to be displayed, thereby achieving the effect of dynamically displaying the OSD ...

Method and device of search new color temperature point

A method of finding new color temperature point is used for a color display. A color temperature point of the highest brightness is formed under the state that the color display radiates the red light, the green light and the blue light with the highest brightness. The new color temperature point finding method is using a calculating method to ensure that the new color temperature point satisfies the specific color temperature for adjustment and loses least brightness.

A method and corresponding device for quick setup of grey value-brightness curve of the display

The invention relates to a method for quickly building a gray value-brightness curve of a display. Part of gray values and corresponding brightness values of the display is obtained and then substituted to a formula for calculation; the variables in the formula are relieved to obtain a gray value-brightness curve.
