ABSTRACT:
A method for the operation of a CID sensor matrix, in accordance with the parallel injection readout method, having coordinate rows and column lines, and sensing elements at the line intersections, in the operation of which the charges of the sensing elements of a row are transferred to the column lines and subsequently serially transferred, over corresponding column lines, to output means, in which the information charges of a selected row are shifted to the associated column line, the charge values on the column lines, are shifted, in parallel, out of the matrix proper into parallel temporary storage positions, and the charge values are serially readout from said temporary storage positions, with the information charges in the matrix proper being simultaneously erased, and following readout, any stored charge values at said temporary storage positions being erased, and to apparatus for practicing such method.
