The present invention discloses a digital image device having an image sensor, a processor and a display for displaying a plurality of pixel data, and each of the pixel data includes a red color value, a green color value, and a blue color value. The white balance correction method of the digital image device comprises the steps of: (a) receiving an original image from the image sensor by the processor; (b) separating a red image, a blue image and a green image from the original image by the processor (C) dividing each of the red, blue and green images into a plurality of blocks by the processor; (d) calculating a color change of each of the plurality of blocks of the red, blue and green images by the processor; (e) respectively calculating a threshold value of the color change of each of the plurality of blocks of the red, blue and green images by the processor; (f) determining whether the color change of each of the plurality of blocks of the red, blue and green images is greater than or equal to the thresh
