Abstract
An imaging element includes a photosensor and a transfer transistor to transfer electrical charges from the photosensor to a charge accumulation node. A selector is configured to receive at least two logic selection signals and to supply an activation signal, which is a function of the selection signals, to a control terminal of the transfer transistor. The selector is configured to receive at least two selection signals, each having a positive voltage when it is at a logic value 1 and a negative voltage when it is a logic value 0, and to supply the activation signal having a negative voltage when the imaging element is not selected.
