System and method of calibrating a display system free of variation in system input resolution

摘要

This invention provides a calibration system and method for multi-unit display systems without a need for switching the system input resolution/configuration of the display system while calibrating. This serves to avoid carrying out a re-synchronization step. As such, this system and method allows for increases speed and reduced likelihood of failure. This system and method also corrects the display system by providing an arrangement that employs a minimum of required changes so as to avoid any changes that can consequently affect the output image of the display system. Calibration of the system of display units occurs free of any changes to the input resolution and this resolution is maintained in a manner that resists change unless specifically required. Moreover, this system and method enables a resolution for the overall system that differs from the sum of the input resolutions of the discrete, individual display units in the collection.

主权项

1. A method for performing calibration on a collection of one or more display units with a system input resolution different from the total resolution of the display units, the method comprising the steps of:
a. changing an input video signal to calibrate the system, free of changing a resolution of the input video signal so as to maintain a current input resolution thereof; b. during the calibration, using a change in at least one of a plurality of settings to at least partially compensate for the maintaining of the current input resolution; and c. calculating a new system correction using the data collected in step (b) and compensating for any artifacts introduced in step (b).
