Embodiment 1

[0032] A kind of JPG picture processing method is provided in the present embodiment, and the equipment that carries out this method is computer, is provided with in this computer and carries out the corresponding program instruction of following operation, and the flow process that this computer carries out picture processing is as follows Figure 4 shown.

[0033] The user provides an original picture in JPG format. JPEG format picture, also known as JPG format picture, is the most common image format, and the file suffix name is ".jpg" or ".jpeg". It is a lossy compression developed by a software development association. Format, JPEG compression technology is very advanced, it uses lossy compression to remove redundant image data, can display very rich and vivid images while obtaining extremely high compression ratio, and can get better image quality with the least disk space .

[0034] In the present embodiment, the image processing process for the JPG format provided by...

Embodiment 2

[0042] Another kind of JPG image processing method is provided in the present embodiment, and this method can be carried out by mobile phone terminal, and the user has stored a piece of format in the mobile phone and is the original picture of JPG format, has the instruction of carrying out following processing procedure in this mobile phone, Thus, the following processing flow is completed, such as Figure 5 As shown, first, the mobile phone reads the attributes of the original JPG image, which includes the inherent attributes of the image such as format information, area, color value, original compression ratio, volume, etc., and then the mobile phone judges the area of ​​the original image, if it is less than 150*150 pixels point, the original image is converted to PNG8 format through the program as the processed image.

[0043] If the area of ​​the original picture is not less than the above-mentioned threshold of 150*150 pixels, the mobile phone then uses a program to per...

Embodiment 3

[0048] Provide a kind of processing method of PNG picture in the present embodiment, the device that carries out this method is a server, is stored with the instruction code that carries out following process in the server, and the user logs in website by mobile phone, and the interface that user selects picture is provided in the website, when When the user selects a PNG image to upload, the server obtains the information of the image and processes the image as follows. The flow chart is as follows: Image 6 Shown:

[0049] First, the server determines attribute information of the PNG image selected by the user, and the attribute information includes transparency, area, and color value.

[0050] PNG format picture, Portable Network Graphics (PNG, Portable Network Graphics), is an image file format. PNG is capable of providing lossless compressed image files that are 30% smaller in length than GIF. The PNG format has three forms: 8-bit, 24-bit, and 32-bit. Among them, 8-bit ...

Abstract

The invention provides a picture processing method, a picture processing device and a picture processing platform. The method comprises the following steps: obtaining attribute information of an original picture; aiming at a PNG picture, firstly performing lossless compression on the original picture, and then judging a transparent characteristic of the original picture; if a transparent pixel point does not exist, judging the area of the original picture or a picture color value; when the area of the picture is less than an area threshold or the picture color value is less than a color threshold, compressing the picture after the lossless compression, converting a format of the picture after the lossless compression into a JPG format, and then performing compression; and obtaining the picture, which has the smaller volume in the two pictures, through a comparison, and selecting the picture as a processed picture. In the scheme, judgments are performed through combinations with the picture transparent characteristic, the color value and the area of the PNG picture, original picture information is represented well in the smaller picture volume, the picture expression effect is improved, and the picture volume and quality cost performance are improved.

Description

technical field [0001] The present invention relates to the field of picture processing, in particular to a picture processing method, a picture processing device and a picture processing platform. Background technique [0002] With the development and popularization of network information technology and electronic information technology, people often use electronic pictures in their daily life, such as mobile phones, digital cameras, etc., all have the function of taking pictures, and the sharing of a lot of image information has become simple and convenient. In many current network platforms, there are functions of picture sharing, such as uploading profile pictures, photo albums and so on. When users use a picture, they often hope that the picture quality is good and the size is small. However, for a picture with a fixed format, generally speaking, the quality and volume of the picture are directly proportional. To obtain a higher picture quality, the picture must meet a...
