Patent ID: 8481956

Claim:
A method of signal processing in a dental radiology apparatus comprising an intraoral sensor that includes an active pixel array produced using biCMOS technology, the pixels being arranged in rows and columns, the sensor delivering an analog output signal produced from the data values held by the array's pixels exposed to radiation, characterized in that, the pixels of at least one array column being optically inactive, comprising: converting the analog output signal into a digital output signal; reading in the digital output signal of one or more data values coming from each optically inactive pixel of an array row; reading in the digital output signal of one or more data values coming from each optically inactive pixel of at least one adjacent row, the relevant pixel(s) of each of the two rows being equal in number and arranged in the same column(s); comparing the data value(s) read respectively for the inactive pixel(s) of a row with the data value(s) read respectively for the inactive pixel(s) of the at least one adjacent row; and according to the result of the comparison, decision-making as to any modification in the output signal of the data values of all the pixels of one of the rows used for the comparison.
