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.

基础设备，电路和网络的研究是基于生物视觉系统进行的，以开发视觉LSIS的基本技术。一个模拟综合电路已开发出其外部视网膜的功能。通过利用连接所有感光器的MOS通道电阻来实现一个简单的网络。通过改变门电压来进行全局适应。还开发了用于局部适应的基本电路。对于运动检测，基于基于昆虫机制构建的相关模型设计和制造了基本的模拟整合电路。结果，在一维空间中检测到移动光点的方向和速度。还研究了基本电路在二维空间中进行运动检测。构建了目标跟踪模型，这对于运动检测至关重要。通过计算机模拟证实了平稳的追求。设计了该模型的基本电路，并通过香料模拟确认其正常运行。这些网络被重新设计，以使用当前的FinePattern技术来增加集成规模。他们将通过kyungpook国立大学的VDEC进行制造，根据外视网膜的基本网络设计和制造了一个大规模的集成巡回赛。两所大学都合作进行了视觉筹码的设计，制造和评估。该研究的结果在国际会议和期刊上提出。
