7. An image processing method comprising a computer processor performing operations of: estimating depth of an input three dimensional (3D) image; detecting a text area included in the 3D image; generating a text mask corresponding to the detected text area; and correcting depth of the text area to be a first depth value based on the estimated depth of the input 3D image and the generated text mask.
