  • Image signal sensing process including altering charges of capacitances
    Patent number: 6198086
    Abstract: In a method for detecting an image signal by means of an array (30) of photosensitive devices (10) with each of which the charge of a capacitance (12) can be altered, an optical signal (20) of each photosensitive device is first detected by means of the following substeps: creating a charge condition of the capacitance with a predetermined voltage (+U_DD), changing the charge of the capacitance (12) either with a photocurrent generated in the photosensitive device (10) by the optical signal (20) or with a quantity derived from the same and detecting the voltage across the capacitance (12) after a predetermined time period, deciding whether the detected voltage lies within a valid range and, if this is so, determining on the basis of the detected voltage a valid signal which characterizes the detected optical signal, and, if this is not so, repeating the cited steps with a time period which differs from the predetermined time period either a predetermined number of times or until it is determined that the
