Image processing method and image processing device using the same

An image processing device, wherein the image processing device further comprises:

• a first correction unit configured to:
• correct a to-be-processed image as a first correction image and rotate the first correction image by an angle according to a first mapping relationship along a correction direction;
• and
• a second correction unit configured to:
• correct the rotated first correction image as a second correction image according to a second mapping relationship along the same correction direction;
• wherein the first correction unit is further configured to:
• divide the to-be-processed image into a plurality of to-be-processed blocks Tr1×q1, wherein the (r1×q1)-th to-be-processed block Tr1×q1 is sequentially corrected according to a parameter r1 in an ascending order and a parameter q1 in an ascending order.
