The invention relates to an image magnification method and system, electronic equipment and a computer storage medium, and relates to the technical field of image processing, and the method comprises the steps: obtaining a to-be-magnified first image and a magnification factor of the first image; performing nearest neighborhood amplification on the first image based on the amplification factor to obtain a second image; performing edge analysis on four corners of each pixel point in the first image to obtain an edge matrix; and adjusting the second image based on the edge matrix to obtain a third image. According to the method, the blocking effect defect problem of the nearest neighbor amplification algorithm can be avoided under the condition that the definition is the same as that of the nearest neighbor amplification algorithm. 本发明涉及一种图像放大方法、系统、电子设备及计算机存储介质，涉及图像处理技术领域，方法包括获取待进行放大处理的第一图像以及所述第一图像的放大倍数；基于所述放大倍数对所述第一图像进行最近邻域放大，得到第二图像；对所述第一图像中每个像素点的4个角进行边缘分析，得到边缘矩阵；基于所述边缘矩阵对所述第二图像进行调整，得到第三图像。本发明能够实现在拥有与最近邻放大算法相同
