Image Acquisition Application
An Android-based smartphone is utilized in this research to implement the image acquisition. Android is a Linux-Kernel operation system, which is running on Android Runtime. The program development platform is the free Eclipse Software Development Kit (SDK). Therefore, we choose an Android operated mobile phone to catch images and transmit image data via HSDPA. In this study, we used a Motorola Defy MB525 smart phone as the client and the remote computer as the server. The CPU is a 800 MHz TI OMAP3610 and the development platform is Eclipse version 3.6.2. The dpi of the camera is 5 megapixels and the Java Development Kit (JDK) is JDK 6. Figure 7 shows the real-time image capture interface and Figure 8 depicts the program of image acquisition and camera control settings
The remote real-time image transformation settings are shown in Figure 9. The function “Camera.PreviewCallback” is exploited for real-time image acquisition and transported to server by the function “DataOutputStream()”. On the other hand, the functions “ColorModel()” and “Raster()” are used for receiving and decoding images on server computer. The result of a real-time image on the server computer is shown in Figure 10, and the remote real-time image transformations are established
