Estimation of image quality in autostereoscopic display

In autostereoscopic display systems which are based on lenticular, barrier, and lens array plates, the quality of perceived images is different in different regions of the viewing zone. In these systems, a visual image is a composition of several view images which depends on the current observer position. A quantification of the visual quality is suggested basing on the inverse number of different view images involved in a composed visual image. This definition of the quality can only be applied directly to the monoscopic seeing. A new method to estimate the quality value for binocular seeing is therefore devised. It is based on the mapping of different regions of the viewing zone onto a uniform map. The map is scanned by virtual probes "equipped" with single/dual sensors expressing observer's eyes for mono/stereo seeing. The virtual readings of both type probes can be represented in a matrix form giving very similar values for both cases. We found a generalized analytical solution which estimates the image quality as a coordinate-dependent function for both, monoscopic and stereoscopic cases. The generalized solution does not depend on the individual interocular distance.
