Mobile apparatus and method for changing image size

Abstract

The invention relates to a mobile device, which comprises a picture acquisition module, a first operation module, a second operation module, a third operation module and a picture formation module. The picture acquisition module is used to obtain the pixel data of the original picture and the template picture. The first operation module is used to operate the accuracy digit of the length and the width of the template picture. The second operation module is used to operate the accumulated value of the length and the width of the template picture and to take the integer from the accumulated value to operate. The third operation module is used to obtain the corresponding relationship of the template picture pixel and the original picture pixel through summation and displacement operation. The picture formation module is used to form new pictures according to the corresponding relationship. And the invention also provides a method for modifying the size of picture for the mobile device. The mobile device and the method for modifying the size of picture cause the original floating-point arithmetic to be replaced with the integer arithmetic and the original multiply operation to be replaced with the additive operation, thereby the processing speed to the picture size of the mobile device is quickened, the time is saved, and the user satisfaction is improved.

Description

technical field [0001] The invention relates to a mobile device, in particular to a mobile device and a method for changing the size of a picture. Background technique [0002] With the continuous development of communication technology, mobile devices have more and more new functions, for example, mobile devices can receive and display external pictures. The speed and slowness of displaying images on mobile devices are generally the focus of attention of users. The size of the external picture is often inconsistent with the size of the picture that the mobile device can display. Existing mobile devices perform floating-point operations and multiplication operations on the external picture to obtain a picture size suitable for display on the mobile device. However, the processing of floating-point operations and multiplication operations is relatively complicated, which leads to a relatively long time for the mobile device to process pictures. If the external picture is lar...

Problems solved by technology

However, the process of floating-point operations and multiplication operations is relatively complicated, which leads to a relatively long time for the mobile device to process pictures. If the external picture is large, it will cause the mobile device to be in the state of processing pictures for a long time, which will affect the user's mood.
