Abstract: A memory for pixel factors has somewhat more than enough capacity for storing pixel factors for all the pixels of a television picture. A special effect pattern for use in fading from one input picture to another is stored in the memory either as a contour or as an area within a contour. Additional memory capacity is used for start addresses for shifting the pattern. The memory is read out line by line to provide a multiplier control signal for one video input of a mixer and a complementary multiplier control signal for another video input of a video mixer. While one set of pixel factor signals is read out from the memory it is possible to write in an increased or diminished pattern contour or area to provide special effect fading.
