The embodiment of the invention provides a method for eliminating Morie fringes of a camera, a mobile terminal and a computer readable storage medium, and relates to the technical field of image processing. The method comprises the steps that a preview image acquired by a camera is acquired; the preview image is recognized to recognize out a display screen area; a light ray parameter of the display screen area and a light ray parameter of a non-display screen area are acquired, and at least one focusing frame ratio is calculated on the basis of the two light ray parameters; according to one ofthe at least one focusing frame ratio, a focusing frame is moved to the first position according with the focusing frame ratio, shooting is conducted to acquire an initial picture corresponding to the focusing frame ratio until initial pictures corresponding to all the focusing frame ratios are acquired, and the picture with the lowest Morie fringe intensity is selected from the various initial pictures to serve as a target picture. According to the method, the picture with fewer Morie fringes can be automatically shot without complex operations of a user.
