Abstract
An image correction method and an image correction device are provided. The image correction method includes the following steps: obtaining a gray level value of a pixel in an image and a frequency domain value of the gray level value; determining whether the frequency domain value is smaller than a first threshold; performing an adaptive gamma correction procedure on the gray level value according to the frequency domain value and outputting the result if the frequency domain value is smaller than the first threshold; outputting the gray level value directly if the frequency domain value is not smaller than the first threshold.
