A linear sensor composed of substantially like-sized segments generates a high definition television signal from a line scan of a motion picture film. By staggering the linear segments and overlapping adjoining ends thereof, the sampled signal outputs of the several segments can be applied to a series of digital filters that operate independently to provide filtered output signals that can be grouped together without processing artifacts at the crossover points. More particularly, the overlapping regions of the linear segments are configured in relation to the processing kernal required by the digital filters such that contiguous, processed samples on either side of each crossover point are derived from sample strings wholly within a respective linear segment.
