Abstract
An image processing method and an image processing system for eye-gaze correction are provided. The method is applicable to an image processing system having a screen and an image capturing device and includes the following steps. A user's face in front of the screen is captured by the image capturing device to generate a facial image. A head offset and an eye-gaze position of the user with respect to the screen are obtained based on the facial image so as to accordingly determine whether to correct the facial image. If yes, the facial image is corrected based on the eye-gaze position and a preset codebook to generate a corrected facial image, where the preset codebook records correction information of multiple preset eye-gaze positions.
