Abstract: The present invention concerns an analysis process of a line transfer photosensitive device.The charge-signal and the charge noise transfers from the columns towards the memory have the same duration and are made by using a same training charge, stored in memory, that must be at least sufficient to allow to pass in high inversion at the beginning of the transfer from the columns towards the memory. The transfers of the charge-signal and the charge-noise from the memory towards the read-out register or the drain have the same duration and are made by using training charges at least sufficient to allow to pass in high inversion at the beginning of the transfer. These training charges are read with the charge-signal or collected with the charge-noise.
