Demura system for non-planar screen

A Demura system, comprising:

• a camera module configured to capture an image displayed on a non-planar screen having a constant curvature during an image-capturing period;
• a distance detection module including a proximity sensor and configured to detect a distance between the camera module and the non-planar screen during a test period;
• a location calibration module configured to carry the camera module and the distance detection module, adjust an angle of the distance detection module, adjust an angle of the camera module and adjust a location of the camera module;
• and
• a processing circuit configured to:
• instruct the location calibration module to rotate the proximity sensor with a predetermined speed and in a predetermined direction during the test period;
• determine whether the location of the camera module deviates from a predetermined location according to data acquired by the proximity sensor during the test period;
• and
• instruct the location calibration module to move the camera module to the predetermined location when determining that the location of the camera module deviates from the predetermined location.

A Demura system, comprising:

• a camera module comprising a plurality cameras for capturing a plurality of images displayed on a non-planar screen at a plurality points of time during an image-capturing period, wherein the non-planar screen has a plurality of distinct curvatures, and the plurality cameras are disposed to aligned with a plurality of straight lines parallel to a side of a swiveling base so that at least one of the plurality of images has a specific resolution;
• a distance detection module configured to detect a distance between the camera module and the non-planar screen during a test period;
• a location calibration module configured to carry the camera module and the distance detection module, adjust an angle of the distance detection module, adjust an angle of the camera module and adjust a location of the camera module;
• and
• a processing circuit configured to:
• instruct the location calibration module to rotate the plurality of cameras with a predetermined speed and in a predetermined direction during the image-capturing period for capturing the plurality of images;
• receive the plurality of images captured by each camera;
• select one of the plurality of images captured at each point of time as a plurality of sub-images, wherein the plurality of sub-images have the specific resolution;
• and
• provide a planar image associated with the image displayed on the non-planar screen by compositing the plurality of sub-images.
