Abstract
A method for generating an orientation image, adapted to an electronic device, includes the following steps. A plurality of input pixels including a current input pixel of an input image is received. Edge detection is performed on the current input pixel in a first and second direction to generate a first current gradient and a second current gradient respectively with respect to the first direction and the second direction. A ratio of the first current gradient to a current gradient absolute sum is calculated to obtain a current ratio, where the current gradient absolute sum is a sum of absolute values of the first and second current gradient. A sign of the second current gradient is extracted to obtain a current sign. The current ratio and the current sign are inputted to a lookup table to obtain an image orientation angle corresponding to the current input pixel.
