ABSTRACT:
A scanner for line-sequentially scanning a film frame by means of linear image sensors in which the charges of the light-sensitive pixels (1) are transferred to two shift registers (4, 5). To enhance the horizontal resolution in the picture display, the outputs of the two shift registers are line-sequentially and alternately connected (10) to the common input of the subsequent signal--processing channel for generating a progressive quincunx structure of the line-sequential pixel charges.
