Readout method and readout device for reading electrical signals from a photosensitive sensor

Abstract

A readout method for reading a sensor includes a matrix of pixels sensitive to a physical phenomenon and delivering an electrical signal the level of which depends on the intensity of the physical phenomenon, the pixels being organized into rows and being connected, via conductors, to readout circuits of the sensor, the readout circuits each comprising an analogue-to-digital converter receiving the electrical signal and delivering digital information depending on the electrical signal. The method comprises the following phases for the readout of each pixel: the matrix of pixels acquiring electric charges; and reading the matrix by transferring the charges acquired during the acquisition phase to the readout circuits, wherein, during the readout phase, multiple successive analogue-to-digital conversions of the acquired charges are carried out in parallel with one and the same acquisition phase. A readout device comprising the readout circuits of the sensor and configured to implement the readout method.
