Abstract: An image correction method is applied to a scanner device. The scanner device includes a main case, a drive module, an optical module, an analog-to-digital converter, a first-in and first-out data buffer, a data flow control unit, a set unit, a data classification unit and a memory storage unit which are electrically connected and assembled in the main case. The scanner device executes a program statement set by the set unit in the memory storage unit to get values for building an update shading table. The scanner device utilizes the update shading table to compensate pixel values corresponding to red, green and blue light of each scanned line of an image for doing a luminance compensation of image pixels corresponding to the red, green and blue light of each scanned line of the image so as to complete an image correction of each scanned line of the image.
