20100328523 | Method of luminance compensation for a camera lens using multiline interpolation - Provided is a method of luminance compensation for a camera lens by performing a multiline interpolation algorithm. Preferably, a plurality of directional lines are radially arranged on a curved surface of the lens. Sampling dots are then designated along the directional lines in equal or variant distances. Steps including a step of determining the location of a target for luminance compensation, a step of obtaining adjacent directional lines by referring to a slope at the target, a step of calculating the correction values and the weights for interpolation are further introduced. The interpolation algorithm is used to restore a correction plane of a whole image. A polynomial equation is preferably used to obtain two correction values of two directional lines with the same radius. Alternatively, a lookup table is introduced to find the two correction values. It's featured that a symmetric or asymmetric compensation for the camera lens is achieved. | 12-30-2010 |
