ABSTRACT:
A visual information processing device has a pair of neural networks which respectively comprise an upper layer and a lower layer of the device. Each of the pair of neural networks comprises a semiconductor integrated circuit having a plurality of neuron circuit regions which are disposed in a matrix form, each of the neuron circuit regions performing a neuron function; a molecule film having a photoelectric function and provided on the semiconductor integrated circuit, the molecule film having (i) a plurality of T.sub.ij signal input sections each performing a wiring function among the plurality of neuron circuit regions, in each of which a T.sub.ij signal representing the bonding strength among the plurality of neuron circuit regions is optically written, and (ii) a plurality of video input sections each performing a sensor function of sensing a visual image in which one pixel corresponds to one neuron circuit region; and a wiring for electrically connecting the semiconductor integrated circuit and the molecule film. Each of the plurality of neuron circuit regions is bonded with the neighboring neuron circuit regions in each of the pair of neural networks comprising the upper and lower layers, and each of the plurality of neuron circuit regions is bonded with the corresponding one between the pair of neural networks.
