Abstract:
A screen calibration method includes acquiring a full screen image displayed on a screen by a camera, acquiring first optical data of a first region of the screen by a sensor, adjusting the first optical data of the first region of the screen according to first calibration parameters for calibrating colors of the first region to approach target optical data, generating second optical data of a second region of the screen according to the full screen image and the first optical data of the first region, generating second calibration parameters according to the target optical data and the second optical data, and adjusting the second optical data of the second region of the screen according to the second calibration parameters for calibrating colors of the second region to approach the target optical data.
