Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of database management, and particularly relates to a color database management system based on active display. BACKGROUND

[0002] In today's highly developed digital display technology, color accuracy has become the core demand of professional fields such as medical imaging, film post-production and industrial design. Although modern display devices (such as OLED, Micro-LED and TFT-LCD) can generate 16.8 million colors (256 3 ) through RGB three primary color mixing theory, the hardware differences between devices cause significant color differences on different screens for the same RGB value.

[0003] Although the existing calibration technology can establish a device-specific calibration curve by measuring 768 primary color levels (256 levels for R / G / B), it faces a key vulnerability: the calibration data lacks a tamper-proof protection mechanism. Once the stored calibration file is mistakenly deleted, maliciously modified or versioned, the system will load the wrong data without warning, causing the color restoration to fail completely, and the user will be difficult to detect. In scenarios that rely on color authenticity (such as film color grading or medical diagnosis), such hidden failures can cause serious consequences, specifically:

[0004] Current calibration schemes rely on local files or simple databases for storage, lack permission control and integrity verification, and calibration data may be tampered with due to operational errors (such as accidental overwriting), software conflicts or unauthorized access, and there is no traceability mechanism;

[0005] When the display device loads the calibration data, there is usually no real-time verification process, so even if the data is abnormal, the system will still enforce the wrong mapping, and the user can only discover the problem after a significant color shift occurs, so the fault response is severely delayed;

[0006] Professional workflows often involve multiple device collaboration (such as main screen / secondary screen / projector), but existing technologies lack a unified database to centrally manage and version control multiple terminal calibration records, making it difficult to ensure color consistency across the entire link.

[0007] Therefore, the present application provides a color database management system based on active display, which fills the weakest data security link in the display technology chain through active defense mechanisms. SUMMARY

[0008] The purpose of the present application is to provide a color database management system based on active display, which solves the existing problems through external device backup and binary tree dynamic solidification.

[0009] To solve the above technical problems, the present application is realized by the following technical solutions:

[0023] combining the number of characters, the number of representations, and the number of extracted pinyins in order to form a group of numbers, and marking it as a characteristic parameter;

[0024] The number of characters refers to the number of characters in the segment, the number of representations refers to the sum of the order in the 26 English alphabet table corresponding to the extracted pinyin characters, and the number of extracted pinyins refers to the number of extracted pinyin letters.

[0025] Further, the same characteristic parameter is updated according to the pinyin corresponding to the characters and the number, so as to ensure that each segment corresponds to a different characteristic parameter.

[0031] If the real-time binary tree is inconsistent with the original binary tree, the corresponding calibration record is marked as changed, and the backup calibration record stored in the peripheral device is used for recovery during calibration.

[0032] Further, the solidification updating method of the binary tree is as follows:
