Problems solved by technology
Due to the different moments of multi-frame images or multi-camera image acquisition, and the camera is in the process of relative motion, it is difficult to ensure that all input images have the same clarity. When we use multi-frame images to improve image quality, if we incorporate the original For blurred images, the clarity of fusion results will be reduced, resulting in the phenomenon that the quality of fusion results of multi-frame images is not as good as that of single-frame images
[0003] The means to avoid multi-frame image quality include fixing the camera on a tripod, or using a better optical image stabilization device to stabilize the camera, but these methods are heavily dependent on hardware, and the shooting scene is limited, making it difficult to enter In the daily application equipment of ordinary users
[0004] In addition, there are many schemes for denoising or de-ghosting through algorithms, but the image clarity of the noise-reduced image or de-ghosting image obtained by the existing image processing algorithms needs to be further improved

The invention relates to an image processing method and device, an electronic device and a storage medium, and the method comprises the steps of obtaining an i-th frame in an image frame sequence, wherein i is an integer greater than 1, and the image frame sequence comprises multiple frames of images; fusing the first i frames of image frames to obtain a fused frame corresponding to the first i frames; determining a target frame with the highest definition in the first i frames; and determining a pixel difference value between the fused frame corresponding to the previous i frames and the target frame, and carrying out image processing on the fused frame corresponding to the previous i frames and / or the target frame based on the pixel difference value to obtain a processed image. According to the embodiment of the invention, the image definition of the processed image can be improved.
Description
technical field [0001] The present disclosure relates to the field of computer technology, and in particular to an image processing method and device, electronic equipment, and a storage medium. Background technique [0002] Image multi-frame noise reduction technology and de-ghosting technology are commonly used technologies in image processing. They are widely used to improve the quality of original images and improve the signal-to-noise ratio in dark fields. For example, in the night scene mode of mobile phones, through continuous shooting Multi-frame images, using multi-frame images for noise reduction, to obtain clear night scene images. Due to the different moments of multi-frame images or multi-camera image acquisition, and the camera is in the process of relative motion, it is difficult to ensure that all input images have the same clarity. When we use multi-frame images to improve image quality, if we incorporate the original For blurred images, the clarity of fusi...
