Abstract:
A method and device for storing image data. The method comprises: receiving image data to be stored (S100); extracting basic information about the image data to generate a header file (S200); according to the basic information about the image data, segmenting the image data according to a pre-set segment size to generate a data file (S300); and storing the header file and the data file, and generating a storage file (S400). By means of this method, image data is stored in the form of double files; basic information about an image can be added into the image; and when an image with a large data volume is stored, the image is segmented according to the pre-set size, and then sequentially stored so that only one or more sub-segments of the image are extracted and displayed when the image is displayed, such that an image with a large data volume can be quickly displayed, thereby improving the efficiency of image display.
