Embodiment Construction

[0040] In order to make the above and other objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention are listed below and described in detail in conjunction with the accompanying drawings.

[0041] Please refer to figure 1 The structure diagram of the automatic color adjustment device of the present invention. The automatic color adjustment device 1 of the present invention is used to automatically adjust the display color of the image output device 50 . Wherein, the automatic color adjustment device 1 can be independent from the image output device 50 , and the image output device 50 is electrically connected to the automatic color adjustment device 1 ; or the automatic color adjustment device 1 can also be placed inside the image output device 50 .

[0042] The image output device 50 can be a display or a projector, etc., and the image output device 50 includes a luminous body 52 and a screen display elemen...

Abstract

The invention discloses a color automatic adjustment method and a color automatic adjustment device, which are applicable to an image output device. The method comprises the following steps of: acquiring the accumulated use time of the image output device; acquiring the corresponding color intensity attenuation value of the accumulated use time; and regulating the color intensity of the image output device according to the color intensity attenuation value. The color automatic adjustment method and the color automatic adjustment device can solve the problem of color attenuation and color shift so as to obtain pictures of a better effect.

Description

technical field [0001] The invention relates to an automatic adjustment method and an automatic adjustment device, in particular to an automatic color adjustment method and an automatic color adjustment device for an image output device. Background technique [0002] Generally speaking, after a period of use of an image output device (such as a liquid crystal screen, a projector, etc.), it will have problems of color attenuation and color shift, so that the screen display image will gradually be distorted. For example, after a projector bulb is used for a long time, the brightness will gradually decrease, and the chromaticity will gradually turn yellow. In addition, the light-emitting source (such as light-emitting diode) of the liquid crystal screen, or even the organic light-emitting diode (OLED, organic light emitting diode) in the organic display, also has the same problem. [0003] In the prior art, there is a sensing element that directly detects the light source at t...
