Research Abstract

Research on fundamental devices, circuits and networks was carried out based on biological vision systems in order to develop basic technologies for vision LSIs.
An analog integrated circuit was developed into which the function of an outer retina was implemented. A simple network was realized by utilizing a MOS channel resistance connecting all photoreceptors. Global adaptation was performed by varying a gate voltage. A fundamental circuit for local adaptation was also developed.
For motion detection, a basic analog integrated circuit was designed and fabricated based on the correlation model constructed with the mechanism of an insect. As a result, the direction and speed of a moving light spot were detected in an one-dimensional space. A basic circuit was also studied for motion detection in a two-dimensional space.
A model for target tracking was constructed, which is essential for the motion detection. Smooth pursuit was confirmed by computer simulation. Fundamental circuits for the model were designed and their normal operation was confirmed by SPICE simulation.
These networks were redesigned to increase the scale of integration using a current finepattern technology. They are going to be fabricated through VDEC.
In Kyungpook National University, a large-scale integrated circuit was designed and fabricated based on the fundamental network of the outer retina. Both universities collaborated for design, fabrication and evaluation of vision chips. Results of the research were presented at international conferences and in journals.
