Abstract
A method for compressing image data is provided. The image data includes a file to be compressed, which includes N blocks to be compressed. The method includes: setting a target data increment of each of the N blocks of the file according to a 0accumulated target data size and an Naccumulated target data size; before compressing an nblock, calculating an (n−1)accumulated target data size of an (n−1)block according to the 0accumulated target data size and the target data increment; when a difference between an (n−1)accumulated compressed data size and the (n−1)accumulated target data size is smaller than a predetermined threshold, removing X least significant bit(s) of a plurality of sets of data in the nblock to generate an updated nblock; and compressing the updated nblock to generate a compressed nblock.
