In stereoscopy, stereoscopic depth distortion is a serious problem in terms of determining the correct depth sense. There have been few studies pertaining to the problem in terms of the focused object distance (FOD). In this investigation, we discuss the FOD as one of the factors inducing an incorrect depth sense in using common stereo camera systems and propose a method for compensating the incorrect depth sense, which is strongly related to the process of demagnifying the size of displayed stereo image on the screen. The incorrect depth sense increases when the FOD becomes shortened. Our method illustrates that the depth sense difference between a correct depth sense and an induced depth error is compensated completely. We verified the validation of our concerns by both a theoretical simulation and a practical experiment.
