  • Device for the filtering of a video signal
    Patent number: 5384602
    Abstract: To filter a signal delivered in interleaved form, there is provision for the introduction, in series, of a filter on half frames having a bandpass transfer function on the horizontal plane and a high-pass transfer function on the vertical plane. It is shown that this filter then carries out a general bandpass transfer function on the total image signal. Steps are taken to make the center frequency of this filter correspond to a desired resolution of the image. It is shown then that by acting in this way it is possible to heighten the contours of the structures. The invention can be applied particularly to medical radiography.
