METHOD OF IMAGE DEPTH ESTIMATION AND APPARATUS THEREOF

A method and an apparatus of image depth estimation are provided. The method includes the following steps. First, a hue value of each pixel in an image is calculated by comparing all color components of each pixel in the image. The hue value of each pixel in the image is associated with a corresponding value, wherein the corresponding value is a first numerical value or a second numerical value. Then, according to the corresponding value of each pixel in the image, a depth value of each pixel in the image is calculated, in which the depth value is used to convert the image into a three-dimensional (3D) image to be displayed on a 3D display apparatus.
