The invention discloses an image processing method and device, and relates to the technical field of image processing technology. The method comprises the steps of obtaining an image to-be-stored; judging whether an image that has already been stored and similar to the to-be-stored image exists or not; on the condition that the image that has already been stored and similar to the to-be-stored image exists, compressing the to-be-stored image in the interframe compression manner according to the stored image similar to the to-be-stored image; and storing the compressed to-be-stored image. The device comprises an obtaining module for obtaining the to-be-stored image; a determining module for determining whether an image that has already been stored and similar to the to-be-stored image exists or not; a compression module for compressing the to-be-stored image in the interframe compression manner according to the stored image similar to the to-be-stored image on the condition that the image that has already been stored and similar to the to-be-stored image exists; and a storage module for storing the compressed to-be-stored image.
Description
technical field [0001] The present disclosure relates to the technical field of image processing, and in particular, to an image processing method and device. Background technique [0002] At present, when a terminal device stores a picture, it usually compresses the picture before storing it. The relevant image compression methods include the Joint Photographic Experts Group (English: Joint Photographic Experts Group, JPEG) compression method. The JPEG compression method is to compress a single picture independently, and its compression principle is to reduce the redundant image information of a single picture. [0003] Since the redundant image information that can be reduced in a single image is limited, the compression ratio (the ratio of the size of the image before compression to the size of the image after compression) of the image compressed by JPEG compression is not high, and storing the compressed image still requires More storage space.
