The invention provides an image resolution improving method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps: carrying out first-levelfeature extraction processing on an original image to obtain a feature map; performing dimension reduction processing on the feature map to obtain a first feature map; performing second-level featureextraction processing on the original image to obtain a second feature map; performing up-sampling processing on the first feature map and the second feature map to obtain a new first feature map anda new second feature map; and carrying out fusion processing on the new first feature map and the new second feature map to obtain an ultra-resolution image of which the resolution is greater than that of the original image. According to the invention, the artifact removing capability can be enhanced, and the quality of the obtained super-resolution image is improved. 本申请提供了一种图像分辨率提升方法、装置、电子设备及计算机可读存储介质；方法包括：对原始图像进行第一层次的特征提
