The present invention relates to a mobile device and a method for controlling same, and the subject matter of the present invention comprises: classifying a received first texture as a static texture or a dynamic texture on the basis of the attribute of the texture; when the first texture is a static texture, classifying the first texture as a compressed texture or an uncompressed texture on the basis of compression application; when the first texture is a static texture and a compressed texture, classifying the first texture as a mipmapped texture or a non-mipmapped texture on the basis of mipmap application; when the first texture is a static texture and an uncompressed texture, classifying the first texture as a mipmapped texture or a non-mipmapped texture on the basis of mipmap application; when the first texture is a dynamic texture, classifying the first texture as a shadow map or a non-shadow map on the basis of the aspect ratio of a screen; adjusting the size of the first texture on the basis of the classified texture attributes; and displaying the first texture according to a control command from a control unit.
