Image correction method and device

The invention relates to the field of image processing, in particular to an image correction method and device. The problem of image color cast caused by a white balance correction method in the priorart is solved. The method comprises the following steps: determining a first white area rule; using the first white area rule to find out a white point threshold value of each image to be corrected;and classifying the to-be-corrected images belonging to the same color temperature, determining to-be-corrected points according to all found white point thresholds, and performing white balance correction on the to-be-corrected points. According to the method provided by the embodiment of the invention, the problem of image color cast caused by different color temperatures and different white color development states can be improved to the maximum extent. 本发明涉及图像处理领域，尤其涉及一种校正图像的方法及装置。于解决现有技术中白平衡矫正方法可导致图像色偏的问题。所述方法包括：确定出第一白区规则；使用所述第一白区规则找出每一幅待校正图像的白点阈值；对属于同一色温的待校正图像进行归类，根据找出的所有白点阈值确定出待校正点，对所述待校正点进行白平衡校正。可见本发明实施例提供的方法可最
