IMAGE SENSOR THAT IS ABLE TO WORK IN A MODE UNDER NORMAL RESOLUTION

摘要

The sensor has a set of elementary pixels (10, 11) forming battery cells including photosensitive diodes (D), and a readout circuit connected to a column bus for allowing acquisition of a charge value of the diode. The battery cells are grouped into sub-assemblies forming macropixels (20), where each sub-assembly comprises a common electrical connection at which each elementary cell is connected by respective reset transistor (T1), so as to allow load sharing between the diodes of the cells of the sub-assembly. The electrical connection is connected to a reference voltage source (VDD).
