Abstract

PURPOSE:To ensure both the contraction and magnification with modulation for a picture without any change of the hue, by sampling the picture element of a supplied picture out of a coded color TV signal in a nonlinear way and based on a certain function. CONSTITUTION:An input picture signal (a) is coded 1 by a sampling pulse K of a writing pulse generator 9 and under the control of an intermittent pulse (n) of an intermittent pulse generator 11. This coded signal is separated to a luminance signal (c) and a chrominance signal (d) through a YC separator 2. For the signal (c), the picture element is sampled by a picture element samping circuit 4 in accordance with the ratio of contraction after the signal (c) passed through a delaying device 3. For the signal (d), the picture element is sampled after a compensation of hue is carried out through a chrominances signal processing circuit 5 and then synthesized again through a mixer 6 to be stored in a memory 7.
