Abstract

We analyzed the apparent depth and size of stereoscopic images and verified the results by a psycho-physical experiment. Random dot stereograms containing horizontal disparity (parallax) were displayed field-sequentially on a CRT display, and the apparent depth and size of the image was measured by using two LED's as a matching index. The conclusions derived are: stereoscopic images are larger than the image on the screen when formed behind it and smaller when formed in front. When an image is formed in front of the screen, its apparent depth saturates as a function of parallax, resulting in a decrease in the sensitivity of apparent depth at large values of parallax. Neither is a linear function of disparity between the left and right images on the screen.
