Abstract

The invention provides an image display method and apparatus. The method comprises the following steps: displaying an image, and obtaining a target image area of the image; displaying the target imagearea in N first windows and L second windows respectively, wherein the window widths and window levels of the N target image areas displayed in the N first windows are different, the enlargement factors of the L target image areas displayed in the L second windows are different, and N and L are positive integers. In this way, by respectively displaying the target image area in the N first windowsand the L second windows, the image display accuracy can be improved, so that possible abnormal images areas in the image can be distinguished more easily.

Description

technical field [0001] The present invention relates to the field of image display technology, in particular to an image display method and device. Background technique [0002] At present, experienced observers are usually asked to observe the infrared images of solar photovoltaic modules to find possible problem areas in the images, and then determine the faulty components caused by the hot spot effect. However, the gray levels of the existing display media are mostly low, and the gray levels of the actual infrared images are mostly higher than the gray levels of the display media, which will make the display media unable to present all the gray levels in the image value; as a result, the accuracy of the infrared image displayed on the display medium is low, which increases the difficulty of observation and makes it difficult for the observer to distinguish the image area that may have anomalies. Therefore, the accuracy of the current image display is low, which makes it ...
