Maturation of the technologies enabling stereoscopic image capture and display offer attractive opportunities for enriching the user experience in hand-held devices, thus expanding possibilities of stereoscopic content creation from experienced stereoscopic practitioners to the general public. Content with inappropriate disparities or artifacts can cause negative experiences. There is therefore a need to ensure the quality of content created with a stereoscopic camera system to ensure positive user experiences and applicability of stereoscopic techniques in the mobile domain. We have investigated how the properties of a stereoscopic camera system can be characterized, and how a range of aspects in the imaging chain and display properties affect perceived disparities and artifacts in the content. Design considerations arising from adapting stereoscopic imaging to hand-held devices have been identified. We propose a methodology for disparity range optimization by basing camera geometry calculations on the limitations in viewing space extremities. A stereoscopic camera testing system with controllable camera parameters and a test scene for generating disparities has been developed to assist in evaluating contributing factors and to confirm the results. As a result, methods and equations for the stereo image calculations are assessed. This paper presents several techniques for reducing unwanted artifacts in a captured scene and improving the quality of the user-created stereoscopic content.
