Abstract
A method for compressing images based on joint photographic experts group (JPEG) standard includes: compressing data of one or more first image blocks with a first compression level to produce compression data of the one or more first image blocks; adjusting the first compression level to obtain a second compression level according to at least one of a data size-related index regarding the compression data of the one or more first image blocks or a transmission-related index regarding transmission of the compression data of the one or more first image blocks; and compressing data of a second image block with the second compression level.
