IMAGE PROCESSING METHOD AND DEVICE

Title:

IMAGE PROCESSING METHOD AND DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/104705

Kind Code:

A1

Abstract:

Embodiments of the present application provide an image processing method and device. The image processing method in the present application is executed by a terminal having a digital zoom function, and comprises: determining a target zoom ratio according to a selection input of a user, and acquiring an image to be processed; processing the image to be processed using a target super-resolution convolutional neural network model to obtain a processed image corresponding to the target zoom ratio, wherein the target super-resolution convolutional neural network model is obtained by training super-resolution convolutional neural network model using a high-definition training image, a low-definition training image, and a mask image. The embodiments of the present application can overcome the problem of declines in image quality, such as definition reduction and noise amplification, introduced by conventional digital zoom.
