Embodiment Construction

[0070] The present invention provides an adaptive image scaling method and device for mobile platform information. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0071] The adaptive image scaling method for mobile platform information provided by the embodiment of the present invention is applicable to various systems. Taking the Firefox OS system as an example, the adaptive image scaling method for mobile platform information is based on compressing according to the number of images. Added an adaptive scaling process based on capacity, so that when there are few images in the attachment and the images are not very large, the image should be kept a...

Abstract

The invention discloses a self-adaptive image scaling method and device of mobile platform information. The method comprises the steps that when an information editing interface is opened to add files, whether a current file can be added or not is judged according to the maximum capacity of an attachment; when the file is added, scaling processing of a corresponding compression level is conducted on all images in the attachment according to the types, the number, the size and the maximum capacity of the attachment of the added files; the surplus capacity of the attachment is detected, a user is prompted to add files continuously when the surplus capacity is available, and when the surplus capacity is insufficient, the user is prompted to delete the file. According to the self-adaptive image scaling method and device of the mobile platform information, self-adaptive compression of the corresponding compression level can be chosen according to the capacity, finite space is completely used, meanwhile, the maximum image accuracy can be maintained, and the demand of users is met.

Description

technical field [0001] The invention relates to image compression technology, in particular to an adaptive image scaling method and device for mobile platform information. Background technique [0002] Currently, the compression mechanism for adding images in information applications (such as SMS and MMS) on the operating system is very simple, resulting in very limited attachment content. Generally, there are three forms of attachment content added in MMS: audio, video and image. For audio and video, there is usually no compression in the sending process, so image compression is the main content of MMS attachment compression. However, in the existing operating systems, compression is triggered when an image is added, and audio and video files are added without any processing. It lacks customization and reversible operations, so the following problems will occur: [0003] 1. When adding attachment content, if you select the image first, in order to ensure the accuracy of t...
