Display correction parameter extraction device, system and method

Abstract

The invention provides a display correction parameter extraction device. The display correction parameter extraction device comprises a communication interface module used for reading actual measurement data; a standard data generation module used for generating standard working data; a standard test image generation module used for generating a standard test image; an adjusting mode processing module used for selecting a to-be-corrected component to be corrected and sending actual measurement data and standard working data related to the to-be-corrected component to the PID adjusting module;a PID adjustment module used for carrying out PID difference operation on the actual measurement data and the standard working data related to the component to be corrected, and carrying out increment; and the adjustment mode processing module is also used for summing the increment and the to-be-corrected component to obtain a corrected test image and generating a correction parameter lookup table. The PID controller has the advantages of mutually independent control parameters, simple parameter selection and the like, and a mathematical model of a controlled object does not need to be provided, so that the adaptability is high, the operation is simple, and the production benefit is improved.

technical field [0001] The invention relates to the technical field of medical display, in particular to a display correction parameter extraction device, system and method. Background technique [0002] In medical monitors, several different color temperature and gamma correction curves are equipped to meet the application in different occasions. In order to extract the correction curve, it is generally necessary to use a color analyzer. If it is manually operated, the workload is extremely cumbersome and the efficiency is low. At present, some manufacturers use software for automatic correction. However, panels from different manufacturers, or panels of different models from the same manufacturer, or even panels of the same model from the same manufacturer have more or less differences.

In order to extract the correction curve, it is generally necessary to use a color analyzer. If it is manually operated, the workload is extremely cumbersome and the efficiency is low.

At present, some manufacturers use software for automatic correction. However, panels from different manufacturers, or panels of different models from the same manufacturer, or even panels of the same model from the same manufacturer have more or less differences. When the products are used in different environments for a period of time Afterwards, this difference will become bigger and bigger. This difference is reflected in the algorithm that the mathematical model of the product has changed, and the general correction software extracts the correction curve based on a certain mathematical model. Obviously, different In theory, the mathematical model of the panel will have some differences. If the difference is small, then the method meets the correction requirements. If the difference is large, it needs to be corrected manually after software correction. The most important point is that the mathematical model itself has undergone a lot of testing. A mathematical system summed up from experience, the extraction of this model also takes a lot of time, so this method is somewhat progressive compared to pure manual extraction, but it is not perfect
