Abstract
The present invention discloses a method and device for storing image data, the method includes: receiving image data to-be-stored; extracting basic information of the image data and generating a header file; partitioning the image data by a preset block size according to the basic information of the image data, and generating a data file; and storing the header file and the data file and generating a storage file. In the present invention, image data are stored as double files, so as to add basic information of an image into the image, and in storing a massive-data image, the image is partitioned by a preset size prior to sequential storage, so that when the image is displayed, only one or several sub-blocks of the image are extracted and displayed, allowing quick display of the image with massive data, improving the efficiency of image display.
