Patent ID: 8212810

Claim:
A method for the calibration of a display unit, comprising a display and an autostereoscopic adapter disc, wherein inaccuracies of the positioning of the adapter disc relative to the display and/or optical parameters of the display unit are compensated or optimized by adjusting the image shown on the display to the actual position of the adapter disc by changing the image in relation to three parameters (i off , α, d) by the following steps: (a) Incrementing or decrementing of a value of at least one of the three parameters of the image and then calculating the perspective (n) for each image element (i, j) in dependence on these parameters, wherein the three parameters represent a shift (i off ) of the adapter disk in a plane of the display, a rotation (α) of the adapter disk around an axis that is perpendicular to the plane of the display, and a distance (d) of the adapter disc from the display, respectively; (b) generating a mask (M n (i, j)) for each prospective, wherein the mask is defined to have a value of “1” for each image element which is to be displayed from the respective prospective, and a value of “0” otherwise; (c) multiplying the image of each prospective (Pn(i, j)) with the mask generated for the respective perspective, and adding the masked perspectives for displaying an image (B(i, j)) on the display; and (d) repeating the steps (a) to (c) for the three parameters, until inaccuracies of the positioning are compensated and/or the optical parameters are optimized.
