<p>The invention relates to a method for controlling a light-sensitive device, for example, a digital X-ray detector including an array of light-sensitive points. The light-sensitive device includes a column conductor, line conductors, and light-sensitive points. Each light-sensitive point is connected between the column conductor and one of the line conductors, and includes a light-sensitive element capable of converting a photon flux into electrical charges, and a transistor capable of transferring the electrical charges to the column conductor based on the control of a signal received by the corresponding line conductor. The invention depends on the presence of a capacitor for cross-coupling between the drain and the source of each transistor in the off state. Said capacitor provides a potential variation to the column conductor upon receiving photons. The method according to the invention comprises steps (21, 22, 23, 24) for comparing the potential variation with a threshold, and a step (25) of reading the light-sensitive points is carried out in the event that the result of the comparison is positive.</p> |
