Projecting system and its color temperature regulation method

Abstract

The invention provides a projection system, comprising a light source and a photoelectric device; the light beam of the light source forms an image after passing through the photoelectric device and then is projected on a screen. The projection system also comprises an adjusting device which comprises an adjusting unit and a control unit; the adjusting unit is electrically connected with the control unit. The control unit is used for analysing the colour temperature value of the projection image and compares the analysed colour temperature value with the colour temperature value prearranged in the control unit; when the analysed colour temperature value is different from the prearranged colour temperature value, the control unit controls the luminous flux of the adjusting unit according to the analysed colour temperature value so as to adjust the colour temperature of the image. The invention also provides a colour temperature adjusting method used for the projecting system. The projection system and the colour temperature adjusting method can adjust the colour temperature of the light beam of the projection image and leads the colour temperature value of the image on the screen to be identical to the given colour temperature value.

Description

technical field [0001] The invention relates to a projection system and a color temperature adjustment method thereof. Background technique [0002] In the projection system, the light source is projected on the screen to display the image through the optical element and the photoelectric adjustment device. color ratio. The higher the color temperature, the more blue components, and the lower the color temperature, the more red components. In general, the user sets the required color temperature in the display menu according to the needs of different scene modes. The display menu has determined several color temperature ranges that can be adjusted before leaving the factory, and the user can choose according to the need. [0003] However, there is generally a certain difference between the set color temperature adjustment range and the color temperature required by the user, and the color temperature required by the user cannot be displayed, and the user cannot adjust the ...

Problems solved by technology

[0003] However, there is a certain difference between the set color temperature adjustment range and the color temperature required by the user, and the color temperature required by the user cannot be displayed, and the user cannot adjust the color temperature.

When the color temperature adjustment range is quite different from the color temperature required by the user, it will affect the color balance of the screen, making it difficult to meet the user's needs.
