Problems solved by technology

The display of massive images will inevitably involve the problem of display speed. Because the increase speed of computer memory can never catch up with the growth rate of data volume, it is unrealistic for the computer to read all the data of massive images into the memory, even if the computer memory is large enough to Read all the data of a massive image into the memory, but the memory is certainly not large enough to open multiple massive images at the same time

Embodiment Construction

[0019] figure 1 Shown is one of the technical line embodiments of the present invention. Due to the horizontal span of massive images, when reading data from the hard disk, multiple positioning and reading are required. When displaying massive images, it is unavoidable to repeatedly deal with the hard disk. Therefore, massive images must be divided into blocks. The purpose is to divide massive images with a large amount of data into multiple pieces of data with relatively small data volumes, number these data blocks, and establish indexes. When querying data, you only need to select the corresponding The required data can be quickly queried, which avoids the line-by-line reading of massive images and saves a lot of time. While the mass image data is divided into blocks, each time the data of the set block size is read and entered into the memory buffer, it will be compressed to form a custom VMD intermediate image file. The specific content of the VMD intermediate image fil...

Abstract

The invention relates to a method for compressing, storing and displaying lots of image data, which comprises that dividing the image data, reading and storing the data into a memory buffer to be compressed to form a laminate data in different resolutions, to be stored as middle image document, releasing the memory buffer, when displays the image, reading the middle image document stored on the disc into the memory buffer, to be copied to a display buffer area, to display the image. The invention can quickly compress, store and display lots of image, as movable display and reduction display, to improve the storage read / write speed and image processing ability.

Description

【Technical field】 [0001] The invention relates to a method for compressing, storing and displaying multimedia images, in particular to a method for compressing, storing and displaying massive image data. 【Background technique】 [0002] With the development of digital image technology and multimedia information technology, the application of massive image data is becoming more and more common, such as aviation and aerospace remote sensing image data, digital data of general and thematic maps, historical documents, multimedia integrated data, medical image data, etc. The display of massive images will inevitably involve the problem of display speed. Because the increase speed of computer memory can never catch up with the growth rate of data volume, it is unrealistic for the computer to read all the data of massive images into the memory, even if the computer memory is large enough to Read all the data of a massive image into the memory, but it is certainly impossible for the ...
