Method for tuning a three-dimensional image and a display apparatus thereof

A method for tuning a three-dimensional image, comprising:

• acquiring an integral image that is composed of a plurality of element images that are used to reproduce a 3D image through a lens array;
• extracting pixel values from each of the element images;
• selecting a range of numbered pixels of every line of one-dimensional pixels of the element image;
• according to pixel numbers of the selected pixels, filling the pixel values of the selected pixels of the one-dimensional pixels into multiple zones divided from the one-dimensional pixels of the element image so as to form a new element image;
• and
• forming a plurality of new element images by repeating steps of selecting the range of pixels of one-dimensional pixels of each of the element image and filling the pixels values of the selected pixels into multiple zones divided from the one-dimensional pixels of each of the element image, so as to form a new integral image;
• wherein the element image is a two-dimensional image and the method is applied to the two-dimensional pixels of the element image, and the pixel values of the selected pixels are filled into multiple zones divided from the one-dimensional pixels of the element image in an ascending order after a descending order, a descending order after an ascending order, and with continuously-duplicate pixel values according to pixel numbers of the selected pixels.
