摘要

针对Visual CNN (cellular neural network)芯片的光接口，提出了一种新的多模光传感器结构。该传感器为用户提供选择光敏器件以及将光产生的电荷转换成相应像素电压的机制的可能性。线性或对数压缩采集模式是可用的。这使得传感器非常适合在非常不同的照明条件下使用。

A multimode gray-scale CMOS optical sensor for visual computers

This paper presents a new multimode optical sensor architecture for the optical interface of Visual CNN (cellular neural net) chips. The sensor offers to the user the possibility of choosing the photo-sensitive device as well as the mechanism for transducing the photogenerated charges into the correspondent pixel voltage. Both linear or logarithmic compression acquisition modes are available. This makes the sensor very suitable to be used in very different illumination conditions.
