Claim Text:
1. An image encoding method, comprising: receiving a plurality of view-angle images each comprising a plurality of pixels; calculating a pixel relative relationship between the pixels according to their colors and locations to generate a plurality of encoding images; and respectively embedding the encoding images in the view-angle images to generate a plurality of embedded images; wherein in the calculation step, the relative relationship between pixels is calculated according to each said pixel and the number of its adjacent pixels with similar color, and the calculation step comprises: calculating each said pixel and a first number of its adjacent pixels with similar color along a first direction; calculating each said pixel and a second number of its adjacent pixels with similar color along a second direction opposite to the first direction; and calculating the relative relationship between pixels according to the square of the first number of adjacent pixels and the square of the second number of adjacent pixels.
