WDR PIXEL ARRAY, IMAGE SENSOR INCLUDING THE PIXEL ARRAY AND METHOD FOR OPERATING THE SAME

摘要

The present invention is based on the WDR pixel array , the so-called 4T pixel structure with high sensitivity characteristics (sensitivity) in low light use provides WDR pixel array having high sensitivity characteristics in Figs. sodium bicarbonate and heightened . Discard overflow charges generated for a very high surge , according to the present invention instead of storing only part , by reading out the charges overflow to the 3T pixel added to the internal operation of a separate transistor or theft or heightened 4T pixel structure without photo diode nor even from the pixel array and heightened baking soda can be implemented WDR pixel array by a high sensitivity characteristics .
