title: Digital vision theory: Boolean logic model.
abstract: Guild (1932) stated the general requirements for processing signals in color vision system and a digital format of his paradigm is developed in this paper. The disk structure generates the digital receptor pulse. The input modalities form sets, linked by intersections, joins, and complement junctions. The synapses are elements in these junctions. Complex synapses form junctions to create Boolean logic processing. A computer program using these Boolean logic functions calculates: Light and dark adaptation responses; Color matching and spectral coordinate functions; Chromatic adaptation; Color shift responses; and Dynamic neural responses. These calculations compare favorably with the experimental data. The processing criteria for signals in the vision system are given by Guild (1932). The analysis in this paper uses his criteria to develop a model of the vision system. A computer program simulates the digital processing of signals from the external photon source to the neural output signals from the ganglion cells in the inner-plexiform layer. The responses are compared with the responses of actual vision systems.
