Method for initialization and stabilization of distortion correction in a head up display unit

摘要

The present invention compensates and corrects temperature and distortion errors within a head-up display system using symbol generation and deflection circuitry. The present invention first measures the gain and offset of the symbol generation and deflection circuitry in a controlled environment to create known controlled settings. The circuitry is then installed in an operational head-up display unit where it subsequently dynamically and continuously measures its gain and offset values and consequently adjusts the gain and offset using an adjusting means in order to approximately match the originally derived control settings.
