Abstract
An optical sensor for a telecine application having a first group of odd sensor elements and a second group of even sensor elements where each sensor element is associated with a control electrode that controls the operation of the associated sensor element. An auxiliary control electrode is also associated with sensor elements of one of the two groups with a charge summing element being coupled to adjacent sensor elements assigned to the first and second group.
Claims7
An optical sensor comprising at least one linear array of sensor elements grouped in a first and a second group containing odd and even sensor elements, respectively,
- each sensor element being associated with a control electrode controlling the operation of the individual sensor element,
- the sensor elements of one group being additionally associated with an auxiliary control electrode controlling the operation of the individual sensor element, and
- a charge summing means coupled to adjacent sensor elements assigned to the first and to the second group, respectively, wherein the coupling is achieved by the control electrode and the auxiliary control electrode, respectively.
