Image sensor operating in a persistence-integration mode
Abstract
A novel solid-state image sensor based on a new charge integration concept is proposed. This sensor is suitable for imaging low-speed or static objects at low light levels. A model of the sensor as well as the experimental results of a single pixel device are presented. The dynamic range is about 110 dB. The linearity is about 0.71 at low-light levels. The signal gain of the device can automatically increase with a decrease of incident light power.
