Embodiment Construction

[0058] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0059] see Figure 10 As shown, the method that the large picture MMS in the mobile phone uses ROI image compression to edit and process comprises the following steps:

[0060] (1) Open the MMS editing interface on the mobile phone;

[0061] (2) According to the user operation, obtain the picture that needs to be inserted into the MMS;

[0062] (3) compare the size of the picture with the limit size of the picture by MMS;

[0063] (4) If the picture does not exceed the limit, then directly insert it into the MMS to complete the MMS editing process;

[0064] (5) Otherwise, first open the picture editing interface;

[0065] (6) Reduce the size of the picture until it fits the screen size of the mobile phone;

[0066] (7) Select the shape of the region of interest ROI according to the user operation, wherein the shape of the region of inter...

Abstract

The invention relates to a method for using ROI image compression to edit large image. Wherein, said method comprises: opening the MMS edit interface of mobile phone to obtain the image inserted into MMS, to compare the size of said image, and if it is over the limit, then opening the image edit interface, to reduce the size to match the screen of mobile phone; according to the user operation, selecting the shape and size of preferred section ROI and selecting the compression qualities of preferred section ROI and non-preferred section, to process image data compression, to insert the compressed image into MMS. With said inventive method, the better effect of compressed image can be obtained than JPEG, while it can reduce the memory capacity of image, and meet the minimum demand of space limit of MMS.

Description

technical field [0001] The invention relates to the field of mobile data communication, in particular to the field of multimedia short messages (MMS) for mobile phones, and specifically refers to a method for editing large-picture MMS in mobile phones using ROI image compression. Background technique [0002] At present, mobile phones have become a necessary communication product for people to carry with them. At the same time, MMS and built-in camera functions have become the basic configuration of mobile phones. From 100,000 pixels to megapixels, the effect of mobile phones taking pictures has undergone a qualitative change, and mobile phones with built-in cameras have gained unprecedented popularity. A large part of the reason why users use mobile phones to take pictures is that mobile phones can provide MMS multimedia messaging services, which can easily edit pictures taken into multimedia messages and send them to friends and relatives to share. Since the operator limi...
