Method and electronic device for obtaining resolution of yuv image

Abstract

The embodiment of the invention relates to the technical field of the data processing, and discloses a method for acquiring resolution of a YUV image, and electronic equipment. The method for acquiring resolution of the YUV image comprises the following steps: acquiring at least two lines of pixel points; taking the first target pixel point as a starting point to acquire the first pixel data segment with a preset length; and then entering a circulating step, wherein the circulating step comprises taking the second target pixel point as the starting point to acquire the second pixel data segment with the preset length, computing a first characteristic difference between the image characteristics of the first pixel data segment and the second pixel data segment, increasing the excursion length, and repeatedly executing the circulating step until multiple computed first characteristic differences satisfy a first preset condition; identifying the width of the YUV image from multiple firstcharacteristic differences; and computing the resolution of the YUV image according to the file size of the YUV image and the width of the YUV image. Through the method disclosed by the embodiment ofthe invention, the automatic acquisition of the resolution of the YUV image is realized, and the analysis speed of the YUV image is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular, to a method for obtaining the resolution of a YUV image and an electronic device. Background technique [0002] Images in YUV format are widely used on display devices due to their advantages of strong versatility and small data volume; existing YUV image analysis is used in many scenarios, such as in the process of image processing and debugging; in YUV In the process of image analysis, the resolution of the YUV image needs to be used, but the YUV image does not have the resolution of the YUV image when it is transmitted and stored. Currently, the YUV image is completed by manually inputting a custom resolution. analysis. [0003] However, the inventors found that there are at least the following problems in the prior art: in the process of analyzing the YUV image, it is cumbersome to manually input the resolution, which makes the analysis of the...
