2 . The method of claim 1 , wherein the stitched image is a rectangular image.

3 . The method of claim 1 , wherein the stitched image is a non-rectangular image, and the method further comprises:
filling vacant areas of the stitched image to form a rectangular image.

4 . The method of claim 3 , wherein the stitching respective sub-images of the image to be output comprises:
determining a sub-image with the largest area among the respective sub-images, and moving other sub-images among the respective sub-images relative to the sub-image with the largest area.

5 . The method of claim 1 , wherein the plurality of sub-images are divided based on a shape of a display area of a display apparatus.

6 . An image jointing method, comprising:
receiving a stitched image obtained by the image processing method according to claim 1 ; extracting respective sub-images of an image to be output from the stitched image; and jointing the respective sub-images to obtain a display image, wherein the jointing the respective sub-images refers to obtaining the display image by an operation inverse to a stitching process of stitching the respective sub-images to obtain the stitched image.

7 . The method of claim 6 , further comprising:
calculating, for the respective sub-images of the image to be output, jointing parameters of the sub-images; jointing the respective sub-images based on the jointing parameters of the respective sub-images.

8 . The method of claim 7 , wherein the jointing parameters include area ratio parameters and offset parameters,
the area ratio parameters include width ratios and height ratios of the sub-images relative to a display area of a display apparatus, and the offset parameters include starting positions of the sub-images in the display area.

9 . The method of claim 8 , wherein the jointing the respective sub-images comprises jointing according to a shape of the display area of the display apparatus.

10 . An image display method, comprising:
