Display Calibration Using Reduced Color Patch Clustering

The patent segments the calibration process by dividing display devices into groups based on their characteristics (such as panel type, resolution, or manufacturing batch). Instead of calibrating each device individually with the same comprehensive process, the system applies different calibration approaches to different segments, reducing overall processing time while maintaining accuracy through targeted calibration strategies.

The patent changes calibration parameters dynamically based on display device characteristics. By adjusting parameters such as the number of calibration steps, measurement intervals, and correction algorithms according to device type and performance characteristics, the system achieves accurate calibration faster for different device segments without applying a uniform time-consuming process to all devices.

The patent extracts and stores only the essential calibration parameters and correction data needed for each display device group, rather than storing comprehensive calibration datasets for all possible device configurations. By extracting only the necessary information (such as key correction values, lookup tables, or characteristic parameters), the system reduces data storage requirements while preserving calibration accuracy.

The patent creates universal calibration models or lookup tables that can be applied across multiple display device types within a group. Instead of storing separate comprehensive calibration data for each device model, the system uses multi-functional calibration profiles that serve multiple devices, reducing overall data storage requirements while maintaining accuracy through shared calibration knowledge.
