Abstract

The invention discloses an image processing method which comprises inputting source portable network graphics (PNG) images, and acquiring red green blue (RGB) values of each pixel point from palette data of the source PNG images. According to the RGB values of each pixel point and a pixel size of a target image, the RGB values of each pixel point of the target image are calculated by a closest point interpolation method. According to the RGB values of each pixel point of the target image, the target image is drawn and displayed. The invention further discloses an image processing device. Target images with different sizes can be established according to different screen sizes, and therefore the same source PNG image can be displayed in screens with the different sizes. The image processing method and the image processing method device have the advantages of simplifying calculation and saving calculative resources of a user terminal.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method and device. Background technique [0002] J2ME (Java 2 Micro Edition) is a highly optimized Java operating environment, mainly for consumer electronic devices, such as cellular phones and video phones, digital set-top boxes, car navigation systems, etc. [0003] In the J2ME architecture, the goal of Connected, Limited Device Configuration (CLDC for short) is to provide a standardized, highly portable, and small memory capacity Java application development platform for devices with limited resources and network access capabilities. Supported devices include mobile terminals; Mobile Information Device Profile (MIDP for short) creates a development application environment for small, resource-constrained mobile devices. [0004] The development of J2ME mobile phone applications is based on CLDC and MIDP specifications. The capacity of mobile phon...
