In this paper, we examine the cardboard effect by varying such image acquisition parameters as lighting intercamera distances, lens focal length, and presence or absence of motion parallax and backgrounds in program production. Subjective evaluation tests show that binocular disparity calculated from camera-separation lens selection and convergence point are dominant factors. The cardboard effect can be effectively avoided or lessened by enhancing increasing the binocular parallax. In case of actual program production, it is practical to use standard lenses or ones close in focal length to standard lenses, and to set camera separation around the same as the average eye separation of human eyes in order to mitigate the cardboard effect. When binocular disparity is small using lenses with long focal length, other cues, such as motion parallax accompanied by the relative movement between subjects and cameras, are effective
