Supersized image loading and displaying method used for mobile internet device

Abstract

The invention discloses a supersized image loading and displaying method used for a mobile internet device. Block image data of a supersized image under different resolutions are stored on a remote network server, and an interface is provided so as to enable the device to be read; when display is needed, a plurality of reading tasks are started to parallelly read the image data; when any one reading task is completed, image data acquired by the reading task is firstly drawn onto a screen; after all the reading tasks are completed, image display in the area is ended; and in the process of taskreading, image data are asynchronously downloaded from a remote network server and are stored in the device, and in the downloading process, and the device can acquire image data of lower resolution from a flash memory for supplementation. The downloaded task reusing mode through multi-resolution storage, parallel reading, data caching and image complementation realizes a quick and smooth loadingand displaying process, the consumption of device resources is effectively reduced, and a better user experience effect is achieved.

Description

technical field [0001] The invention relates to a method for loading and displaying super-large images on mobile Internet devices, in particular to a method suitable for loading and displaying super-large images such as digital slices on mobile devices. Background technique [0002] Smartphones, tablet computers and other mobile Internet devices represented by Apple's iPhone and iPad have received increasing attention and applications in many industries due to their powerful network connection functions and excellent user experience. For example, in the field of telepathology, medical experts can view digital slides anytime and anywhere through these mobile devices, and perform remote communication and diagnosis. [0003] Due to the considerations of portability and power consumption, mobile Internet devices generally have low processor performance, small screen size, small memory capacity, and limited flash memory (disk) capacity. However, super-large images such as digita...

AI Technical Summary

Problems solved by technology

[0004] First, it takes a long time to transmit all image data through the network;

[0005] Second, the size of the image is too large to be fully displayed on the screen of the mobile Internet device;

[0006] The third is that the amount of image data is too large to be fully loaded into the memory of the mobile Internet device for processing;

[0007] Fourth, the flash memory (disk) capacity of mobile Internet devices is very limited, and it is impossible to store a lot of image data locally
