Abstract

This article presents a method of color transmission of full depth stereoscopic television that is compatible with monocular reception on a standard television set. Both channels are compressed onto a standard single channel bandwidth format with negligible loss of quality. Life is aligned with gravity, trees grow up and water lies flat, and, therefore, most images have a spatial frequency spectral density containing stronger horizontal and vertical components than diagonal. Perhaps in adaptation to this, the human eye also is anisotropic in sensitivity by typically 25%. Multiplying the biases of both the image and eye yields the perceived importance, i.e., energy sent times attenuation at the receiver, which when plotted on a two-dimensional image spatial frequency graph gives a diamond-shaped bandwidth requirement.
