Abstract
A deformable lens, deformable micro-mirror array, or combination thereof adjusts an image projected onto a screen to modify that image to compensate for small imperfections in the flatness of the surface the video is being projected onto. Initial calibration can be performed to create a screen profile, that is then used to adjust the optics to compensate for the detected screen anomalies. An initial grid projected onto the screen may be used for this purpose, with a high resolution camera imaging the grid and the perpendicularity, straightness and sharpness of the grid lines then being assessed by a processor to calculate the necessary optical modifications to modify the projected image such that the grid lines are straightened and aligned. In another embodiment a scanning laser is used to assess screen flatness and uniformity with pixel level precision.
