| Abstract(in English) | We have investigated a excellent method to extend the dynamic range of a CMOS image sensor and product trial sensor array. The resolution of the sensor is QVGA. The sensor has two marked features. First, it effectively takes advantage of negative feedback method to set any mid-voltage into a PD-capacitance a pixel circuit while in motion. Second, we implemented quasi-holding each pixel value by resetting the pixel-output voltage to the PD-capacitance. We offer an extending dynamic-range of a CMOS image sensor with a help of an individual selecting the setting mid-voltage or the quasi holding for the each pixel. We can drastically reduce external memories that are need for our previous method. The trial chip was fabricated TSMC 0.25μm CMOS technology. Pixel size is 5um x 5um and fillfactor is 40%. |
