The present invention relates to an image correction method for correcting an output change due to unconsidered variables. According to the present invention, the method includes the following steps: dividing an initial correction image into at least two sub-regions when the initial correction image is generated by correcting the current image; calculating the noise variance of the sub-regions based on image values obtained when the initial correction image is generated; calculating changes in the noise variances of the initial correction image based on the noise variances; generating a final correction image by correcting the initial correction image based on the changes in the noise variances; and outputting the final correction image. |
