Abstract

We propose a novel solid-state image sensor based on a new charge integration concept. 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 is presented. The dynamic range is ∼110 dB. The linearity is γ ≃ 0.71 at low-light levels. The signal gain of the device can automatically increase with a decrease of incident light power.
