A method of compressing a texture image for use in generating a 360 degree panoramic video is provided. The method including the steps of: receiving an original texture image for a sphere model, wherein the original texture image is an image with a rectangular shape and includes a plurality of pixel lines and each of the pixels lines has a corresponding spherical position on the sphere model; determining a compression ratio of each of the pixel lines according to the corresponding spherical position of each of the pixel lines; and compressing the pixel lines with the compression ratios corresponding thereto to generate a compressed texture image with a non-rectangular shape, wherein the compressed texture image is further being mapped to the sphere model to generate the 360 degree panoramic video.
