Abstract

The invention discloses an image processing method and electronic equipment. The method comprises a step of collecting and obtaining a first image comprising a first facial object through an image collection unit in the electronic equipment, a step of obtaining the first pixel ratio of the first facial object in the first image, a step of determining a first filtering parameter according to the first pixel ratio, a step of carrying out one-dimensional filtering on the first image in the first direction of an image coordinate system, and obtaining a first filtering image, and a step of carrying out one-dimensional filtering on the first filtering image in a second reaction which is orthogonal to the first direction in the image coordinate system, and obtaining a second image.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an image processing method and electronic equipment. Background technique [0002] With the rapid improvement of network bandwidth and the development and popularization of hardware equipment, based on the Internet and mobile Internet terminals, real-time transmission of human voice, images and videos through mobile phones and other communication devices has become a mainstream communication method. [0003] In the prior art, when a user uses a mobile phone to make a video call, in order to realize the user's beautification function, a super camera is usually arranged on the front end of the mobile phone, and the CPU of the mobile phone is used to process the image to realize the beauty function of the camera; Face detection is used in the preview, and the CPU is used as the computing unit to perform real-time filtering on the face area to achieve real-time beauty effects. ...
