Paper Abstract

Perspective distortion will occur in stereoscopic 3D (S3D) when the relative disparity between elements generates a depth not in accordance with the relative size of the presented objects. Subjective tests have been conducted using test sequences where shooting parameters are perfectly known and where vergence/accommodation conflict is not predominant. Perspective distortions will occur with some of the sequences, depending on viewing conditions. People were asked to qualify sequences in term of naturalness and visual comfort. Results of test revealed a clear correlation between perspective conflict and visual discomfort perceived. Whatever the shooting condition, parallel or toed-in cameras, results are similar. A factor between depth and perspective can be calculated for each shooting configuration and viewing condition. This factor seems a relevant indicator to evaluate the comfort of S3D content perception. Subjective tests allowed to better understand the link between perspective conflicts and visual comfort. Next, studies will be conducted to extend these tests to cinema conditions were the range of viewing conditions is larger.
