Description

Method for reducing picture chromatic aberration of different projectors

Technical Field

The invention relates to the technical field of projector use, in particular to a method for reducing the picture chromatic aberration of different projectors.

Background

The final images projected by the projector have obvious differences in color states of different machines due to errors and even assembly differences of the light source modules and the electronic modules, and generally, the differences of each machine can be reduced in a factory through means such as module screening matching and assembly tolerance reduction, but the methods consume great manpower, material resources and time. In the prior art, because of the difference of the light source itself, the error of the electronic components and the tolerance in assembly, if not processed, the color temperature error of the finally projected picture can reach hundreds of K or even thousands of K, and the color coordinate error can be larger than plus or minus 0.1, thereby causing the obvious difference of picture colors among different machines.

Disclosure of Invention

In order to solve the above-mentioned drawbacks, an object of the present invention is to provide a method for reducing color differences of different projector images, which can effectively reduce the color differences of the projector images.

In order to achieve the purpose, the technical scheme of the invention is as follows: a method for reducing the chromatic aberration of different projectors, the equipment used in the method comprises a computer connected with a projector to be tested, an optical illuminometer connected with the computer and a plurality of samplers connected with the optical illuminometer, wherein the samplers are arranged on a projection screen for the projection of the projector to be tested;

the method comprises the following steps:

1) pre-sampling pictures of different projectors by using an optical illuminometer;

2) transmitting the data sampled by the optical illuminometer to a computer, calculating by the computer, comparing the calculated data with a preset target range, and adjusting the target range;

3) the adjusted data is transmitted back to the projector to be measured through the computer, and the projected pictures of different projectors finally accord with the set color quality through repeated adjustment, so that the color difference phenomenon among different projectors is reduced or narrowed.

The invention has the beneficial effects that: the image chromatic aberration of different projectors can be effectively reduced; all be computer automatic control in the accommodation process, can avoid artifical manual adjustment possible error, and need not consider light emitting source body difference and electronic component error, save down the time of huge artifical raw materials screening collocation combination, improved work efficiency.
