Abstract
The invention relates to a screen alternate display method in proofreading. Two images to be compared are aligned strictly through using a computer vision technology, and display alternately in a time-sharing mode in one window. If the two images are identical, human eyes see a static image, and do not find that actually two images display alternately. If differences exist between the two images, it seems like that only the differences are moving in a static background, and human eyes can rapidly catch the differences which change alternately. By means of a computer image processing technology, the technologies such as filtering unrelated colors for images, changing the color images into gray images, and changing different pixels which are visually identified through a computer into a color which is so different from other colors are used for displaying the differences in the images directly to facilitate the human eyes to identify and judge. According to the screen alternate display method in proofreading, differences can be caught rapidly by a person, the time and energy are saved, the usage in the proofreading of texts or images is facilitated.
