[origin: US5854659A] PCT No. PCT/EP96/01760 Sec. 371 Date Jan. 7, 1997 Sec. 102(e) Date Jan. 7, 1997 PCT Filed Apr. 26, 1996 PCT Pub. No. WO96/36175 PCT Pub. Date Nov. 14, 1996In a process for processing a first video picture with image points in m1 lines, whose image points in the l1-th line have an intensity I1(t, l1) depending on a parameter t, in particular depending on time, for generating a second video picture with m2 lines, the respective intensity I2(t, l2) of an image point in the l2-th line of the second video picture is interpolated from the intensities of the image points of the first video picture I1(t, l1), wherein I2 is obtained according to the following equation: I2(t,l2)=Max(J(t,l2)+ 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 is provided for partial compensation of negative intensities of the discretized signal waveform J so that the interpolation with respect to the lines is effected with A as a freely selectable amplitude of positive value according to the following equation: <IMAGE> An apparatus contains corresponding circuit parts for generating the second video picture according to the indicated process.
