  • Television camera
    Patent number: 4200887
    Abstract: A television camera in which during picture pick-up a same, non-interlaced line raster of lines of half the standard line period are processed in a standard field period. Thereafter signal processing such as a vertical aperture correction and/or an interlace-flicker reduction, takes place in an advantageous manner without a field period delay for improving the picture quality by combining the information of spatially directly adjacent lines. Thereafter signal expansion of the information from half the standard line periods to the standard line periods take place so that ultimately a video signal in accordance with the standard is obtained.
