Method for speedy presentation of ultra-precise image in network environment

Abstract

The invention provides a method for speedy presentation of an ultra-precise image in the network environment. The method for the speedy presentation of the ultra-precise image in the network environment comprises the following steps of carrying out X-stage sampling on a target high-precision image P0 according to the resolution ratio of the target high-precision image to obtain an image P1, an image P2, ..., and an image Px, wherein the resolution ratios of the image P1, the image P2, ..., and the image Px become smaller gradually, X>=1, and X is an integer; blocking is carried out on each image Pi of the image P0, on each image Pi of the image P1, on each image Pi of the image P2, ..., and on each image Pi of the image Px, and obtained blocks are saved in a transverse index saving mode, in a longitudinal index saving mode and in a recursion cross saving mode; when a request for presenting the image P0 with a pointed resolution ratio is received, a storage medium is searched, and an image Py with a resolution ratio closest to the pointed resolution ratio is selected; the image Py is then displayed on a screen. According to the method for the speedy presentation of the ultra-precise image in the network environment, due to the fact that the layering and blocking technique is adopted, the target image is saved from multiple dimensions, and therefore the required image can be read and presented fast and image browsing experience is improved for users.

Description

technical field [0001] The invention belongs to the technical field of data display, and in particular relates to an extremely fast display method of super-precision images in a network environment. Background technique [0002] In recent years, with the continuous improvement of computer software and hardware technology and the rapid development of multimedia technology, the demand for fast reading and display of ultra-fine images through the computer or network environment has also increased. [0003] The traditional image storage method is: one-dimensional storage of the entire image of the ultra-fine image, and the resolution of the stored entire image is the highest resolution, therefore, limited by the network bandwidth, computer memory capacity and processing power, from It is often time-consuming to download images from the web server to the client. The resulting result is: when the user needs to browse a certain image, it takes a long time before the required image ...

[0003] The traditional image storage method is: one-dimensional storage of the entire image of the ultra-fine image, and the resolution of the stored entire image is the highest resolution, therefore, limited by the network bandwidth, computer memory capacity and processing power, from It is often time-consuming to download images from the web server to the client. The resulting result is: when the user needs to browse a certain image, it takes a long time before the required image can be displayed on the display, thus reducing the user's workload. browsing experience
