Printer Color Calibration via Multi-Shot Patch Averaging

The patent applies different measurement methods to different types of patches based on their specific characteristics. Second patches (user-specified colors) are measured multiple times with different exposure conditions to capture color variations, while first patches (predetermined colors) are measured with standard methods. This local differentiation resolves the contradiction by optimizing measurement accuracy for patches that require it without unnecessarily complicating the measurement of all patches.

The patent introduces dynamic measurement parameters by varying exposure conditions (number of shots, exposure time) based on patch type and color characteristics. The measurement system adapts its parameters dynamically - using multiple shots with different exposure times for second patches to capture a range of color values, while using fixed parameters for first patches. This dynamic approach improves accuracy where needed while maintaining efficiency elsewhere.

The patent applies partial action by performing multiple measurements only on second patches (user-specified colors) that require high accuracy, rather than measuring all patches multiple times. The system selectively applies the time-consuming multi-exposure measurement process only where necessary, achieving improved accuracy for critical patches without proportionally increasing total measurement time for the entire patch set.

The patent changes measurement parameters (number of shots, exposure time) based on patch type and color characteristics. By adjusting these parameters dynamically - using more shots and varied exposure times for second patches while using fewer shots with standard exposure for first patches - the system optimizes the balance between measurement accuracy and time consumption, achieving high accuracy where needed without excessive time investment across all measurements.
