Abstract

The invention provides an image processing method and an image processing device, wherein the image processing method comprises the steps of acquiring a to-be-processed image, defining a first area in the to-be-processed image, wherein the first area is an area which comprises a preset object or a preset area; performing brightness fuzzing processing on the to-be-processed image for obtaining a first image; extracting the contour of the first area in the first image, and calculating a brightness determining threshold of a contour boundary, and determining contour boundary information of all contours in the first image according to the brightness determining threshold; performing brightness information coarse quantifying processing on the to-be-processed image for obtaining a second image; and by means of the contour boundary information of all the contours in the first image, performing reinforcing processing on the contour boundary in the second image, and obtaining the processed image. The image processing method and the image processing device improve an image filter photographing effect through utilizing a contour extraction mechanism and brightness quantification grade increasing mechanism, thereby effectively settling a problem of too many pocks in an existing filter photographing effect of the image.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] Smart terminal camera application is a very widely used function. In order to improve the practicability of the camera application, many image processing functions are embedded in the application, and filters are one of them. However, the filter in the prior art is limited by the simplicity of its design device, and the processing effect is often unsatisfactory. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an image processing method and device, aiming at solving the problem in the prior art that the obtained effect image is not clear due to the simple design of the filter in the application of the smart terminal camera. [0004] An embodiment of the present invention provides an image processing method, including: [0005] Acquire ...
