Abstract

The invention relates to an image processing device capable of achieving multiple-screen image displaying and a processing method thereof. The processing device comprises a two-dimensional mobile platform, a color sensor probe, a computer and a real-time addition and correction module, wherein the two-dimensional mobile platform is arranged facing the project direction of a peripheral to-be-added-and-corrected multiple-screen display device; the color sensor probe is connected on the two-dimensional mobile platform; the computer is connected with the two-dimensional mobile platform, the color sensor probe and the to-be-added-and-corrected multiple-screen display device; and the real-time addition and correction module is connected with the computer. According to the an image processing device capable of achieving multiple-screen image displaying and the processing method thereof, the high-precision color sensor probe which can accurately move and locate on the two-dimensional mobile platform and the computer which has a color analysis function are adopted to analyze color uniformity of a picture which is projected by the to-be-added-and-corrected multiple-screen display device, and the real-time addition and correction module is used for adding and correcting, and repairing chrominance and luminance of the picture.

Description

technical field [0001] The invention relates to an image processing technology, in particular to a picture processing device and a processing method for realizing multi-screen image display. Background technique [0002] As we all know, when a projector displays a solid-color picture, due to the lens, the convergence of the light source, etc., there are often local color casts or partial dark situations. Specifically, the red, green and blue light sources of the projector have their own Certain divergence, it is difficult to achieve complete uniformity during mixing, resulting in the phenomenon that the center is brighter and the surrounding area is darker. In addition, it is difficult for the lens to truly achieve "seamless halo", which will also cause certain projection screen edges during imaging. Therefore, in order to improve the uniformity of the projected picture, most of the domestic and foreign countries adopt digital image correction technology. (2) adopting the m...

AI Technical Summary

Problems solved by technology

[0004] 1. When using a CCD device to shoot a large display screen, there will be a problem of corner data collection distortion due to the angle of view;

[0005] 2. The CDD device is expensive, and the device structure is precise, and the cost of use and maintenance is high;

[0006] 3. Since the brightness sensor is statically arranged, the number of sensors is very large, and the system is huge and complex;

[0007] 4. The accuracy of the brightness sensor is not high enough, resulting in inaccurate collected data;

[0008] 5. The consistency of each brightness sensor is not good enough, resulting in different collection standards for each point;

[0009] 6. Maintenance is difficult. Once a brightness sensor in the system is broken, the entire sensor system needs to be recalibrated
