Abstract (en)
[origin: WO9946935A2] In a method of processing input image and/or data signals (Ri, Gi, Bi) having an input frequency (Hi) and a number of active input lines, the input image and/or data signals (Ri, Gi, Bi) are written into a buffer (LM-R, LM-G, LM-B) at the input frequency (Hi), and output image and/or data signals (Ro, Go, Bo) are read from the buffer (LM-R, LM-G, LM-B) at an output frequency (Ho) other than the input frequency (Hi) thereby ensuring that the output image and/or data signals (Ro, Go, Bo) have a number of active output lines other than the number of active input lines.
