An image correction device includes a coordinate transformation unit, a parameter value determination unit, and a correction value calculation unit. The coordinate transformation unit receives first coordinates of at least one pixel data of an illuminated pattern under a first coordinate system, and transforms the first coordinates into second coordinates under a second coordinate system, wherein the second coordinate system is rotated relative to the first coordinate system by an angle with respect to an optical center of the illuminated pattern. The parameter value determination unit determines a respective value of at least one correction parameter according to the position of each of the at least one pixel data in the second coordinate system. The correction value calculation unit calculates an image correction value of each of the at least one pixel data according to the second coordinates and the respective value of the at least one correction parameter.
