Abstract

This paper deals with human factor requirements for the conception of a stereoscopic camera made up of two cameras. With this concept, geometric, optic, and electric differences between the two cameras are possible. These differences have a direct influence on the subjective quality of natural stereoscopic images. In this context, we describe the study of the admissible contrast differences between the two channels of a stereoscopic camera. The main aim of this analysis is the definition of the acceptability thresholds of the defects produced by an inadequate adjustment of the white and black levels between the two cameras. In both cases, the acceptability thresholds are determined with subjective assessments. The studies on the white and black levels are focused on the red, green, and blue levels of each of the two views. The recommendations are aimed at ensuring comfortable images to look at in a stereoscopic television service.
