Picture display method, device and equipment and storage medium

Abstract

The invention discloses a picture display method, device and equipment and a storage medium, and the method comprises the following steps: firstly, reading an original picture input by a user, and loading and storing original data of the original picture; analyzing the original data, compressing the original data according to the size of the display window, performing picture conversion to form a first compressed picture, and displaying the first compressed picture; receiving an amplification operation instruction of a user on the first compressed picture; selecting local original data matched with the size of the display window from the original data according to the amplification operation instruction and the size of the display window; and then analyzing and compressing the local original data, performing picture conversion to form a second compressed picture, and displaying the second compressed picture. Therefore, the large picture can be amplified and displayed in real time; the use of the memory in the amplification and display process is reduced, and the loading time of the oversized picture is shortened.

Description

technical field [0001] Embodiments of the present invention relate to the field of image display technologies, and in particular, to a method, device, device, and storage medium for displaying pictures. Background technique [0002] With the rapid development of information technology, in the semiconductor inspection equipment industry, the target image of the machine vision system has more and more pixels, and the size of the image file is also increasing. For example, if a 300mm wafer is covered with chips with a size of 400um*400um, the number of chips on the wafer will exceed 500,000. Before defect detection, the equipment first needs to take pictures of the more than 500,000 chips, and then perform defect detection, and stitch the images of more than 500,000 chips to form a full picture of the wafer. The pixels of the full picture of the wafer will be Reaching tens of billions, even after compression, the image file size of the final full image of the wafer will exceed...

Problems solved by technology

[0003] This has very strict requirements on the relevant software for image processing. It is a basic requirement to partially zoom in on such super-large images. However, the current mainstream image processing software has the following problems: cannot load super-large images, resulting in images that cannot be displayed at all; cannot provide Smooth interactive operation experience for super large pictures, such as typical real-time zoom viewing function; it needs to consume several times the size of the picture in memory space, occupying too much CPU resources, etc.
