In this paper, we introduce the mobile embedded system implemented for capturing stereo image based on two CMOS camera module. We use WinCE as an operating system and capture the stereo image by using device driver for CMOS camera interface and Direct Draw API functions. We send the raw captured image data to the host computer by using WiFi wireless communication and then use GPU hardware and CUDA programming for implementation of real time three-dimensional stereo image by synthesizing the depth of ROI(region of interest). We also try to find and declare the mechanism of deblurring of CMOS camera module based on the Kirchhoff diffraction formula and propose a deblurring model. Synthesized stereo image is real time monitored on the shutter glass type three-dimensional LCD monitor and disparity values of each segment are analyzed to prove the validness of emphasizing effect of ROI.
