Abstract: In a process for processing a first video picture with image points in m.sub.1 lines, whose image points in the l.sub.1 -th line have an intensity I.sub.1 (t, l.sub.1) depending on a parameter t, in particular depending on time, for generating a second video picture with m.sub.2 lines, the respective intensity I.sub.2 (t, l.sub.2) of an image point in the l.sub.2 -th line of the second video picture is interpolated from the intensities of the image points of the first video picture I.sub.1 (t, l.sub.1), wherein I.sub.2 is obtained according to the following equation:I.sub.2 (t,l.sub.2)=Max(J(t,l.sub.2)+.DELTA.;0),where the values J, with respect to the lines, represent discretized values of a signal waveform given by the sampling theorem and in which an offset .DELTA.

Abstract: In a video system for displaying a video picture composed of image points, whose color values and/or brightness values can be stored sequentially, according to a first set of parameters with predetermined parameter values containing number of lines, number of image points, line frequency and frame frequency as parameters, in an image storage which can be read out in accordance with a second set of parameters with different or identical parameter values for the parameters for displaying the stored video picture by means of a display device, the display device contains an individual light source which can be controlled in accordance with the color values and/or brightness values of the image points and whose light bundle can be projected onto a picture screen via an optical system, wherein the optical system has a raster scanning device by which the light bundle can be directed onto the picture screen on optional points within an image field for displaying the video picture of suitable dimensions and for which
