Apparatus and methods for two point tone reproduction curve calibration
Systems and methods provide increased accuracy in recalibrating the tone reproduction curve (TRC) for a photoelectric image sensor that senses density values. The sensor outputs sensed density values for tone patches. A recalibrated TRC is calculated from the original TRC, the known densities of the...

| Zusammenfassung: | Systems and methods provide increased accuracy in recalibrating the tone reproduction curve (TRC) for a photoelectric image sensor that senses density values. The sensor outputs sensed density values for tone patches. A recalibrated TRC is calculated from the original TRC, the known densities of the tone patches, and the sensed density values of the tone patches. |
