Abstract:
PURPOSE: A calibrating device of a camera module is provided to calibrating differences of optical properties of left and right images of a binocular camera on a real time basis by photographing a plurality of rotating test boards. CONSTITUTION: A calibrating device of a camera module comprises a test unit(110) and a calibration unit(120). Two or more test boards are connected to the test unit so that the test unit rotates at a preset angle. The camera module photographs the images of the test boards. The calibration unit receives the images photographed by the camera module, thereby calibrating optical properties of the images.

PURPOSE: A stereo camera module and a stereo camera thereof are provided to reduce manufacturing costs by removing a correction IC. CONSTITUTION: A first camera(111) and a second camera(112) of a camera unit(110) are separated at a set interval. The first and second cameras receive a left image and a right image, respectively. A correction coefficient storage unit(120) stores a correction coefficient. The correction coefficient indicates how much the first and second cameras get out of a preset arrangement state.

Abstract:
PURPOSE: A 3D camera system and a convergence angle control method are provided to perform a convergence angle correction process with a line movement method, thereby reducing the amount of calculation. CONSTITUTION: An image compensation unit(120) compensates a binocular image. A filter unit(130) detects a reference line of a left-eye image. A line memory unit(140) stores data for the detected reference line and a reference line of a right-eye image corresponding to the reference line. A convergence angle control unit(150) calculates image control amount which corresponds to a convergence angle of the binocular image through comparison calculation of the reference line data. The convergence angle control unit generates an optimized synthesis image of the binocular image by applying the image control amount.

Abstract:
PURPOSE: A barrier panel and a stereoscopic image display apparatus and method are provided to produce a multi view glassless 3D image display by controlling brightness of a barrier area. CONSTITUTION: An image display device comprises an image panel(30), a barrier panel(10), and a controller(50). The image panel comprises a plurality of pixels and displays an image for a stereoscopic image. The barrier panel is corresponded to a front side or a rear surface of the image panel. The barrier panel controls brightness according to each barrier area. The controller controls the brightness according to each barrier area and displays the stereoscopic image from the image panel.
