Research And Implementation Of Camera And Effects Mode Based On Android Platform

In recent years, the combination and promotion of electrical information technology and intelligent mobile terminal, the mobile terminal equipment also entered a period of rapid development. The Android operating system is combined developed by Google and the open mobile phone alliance, has become the development and application of operating system platform for mainstream mobile intelligent terminal because of the openness of hardware and software, strong expansibility, source code open source and smooth user experience. With the platform is becoming more and more powerful and rich, people’s requirements for the application are are also increasing. The camera built in Android provide users with the simple functions of previewing, taking photos and video recording.The design of application and browse interface is monotonous. To rich and meet the customer’s requests of taking photos and browsing, it is of great research and practical value to develop the camera application of the Android and increase the effects mode function, and design the individuation of the photo album function.Under this background, the main work of this paper is to develop camera real time special effects mode and show photos with effects based on the hardware platform of android system and utilizing the native camera. According to the customer demands the paper designed the development of camera applications on the Android platform, to achieve the personalized interface and special effects of taking photos and the camera view mode.The research content mainly includes:(1) Analysis of the Android system architecture, application development module and related technology, a detailed analysis of the calling flow of camera, and designed feasible solution of real time special effects Camera mode using camera API.(2) In real time special effects based on Android camera mode of various specific algorithm analysis and implementation, the Open CV library ported to the Android system, combined with the method of mature Open CV image algorithm library provides written sp-ecific algorithm, called by JNI specific algorithm library, the realization of various types of real-time effects previews.(3) Analysis of the camera album display and browse module, such as 3D display i-ncreased and automatic playback switch picture browsing mode, display the browser can c-hoose a different way to photograph.In the paper, the application of the eclipse is developed in the Windows development platform, combining library Open CV that can be transplanted to Android platform computer vision to achieve real-time camera design and special effects Camera application on the Android panel. The test showed that it is need to continue to explore and research of the application of the effects of changes in the processing speed of gesture interaction. It is a certain guiding significance and application value for the development of the design of Android system on the effects of image algorithm and camera functions.
