PURPOSE: To inexpensively evade a trouble such as deterioration in recolution and a generation of fringe pattern, etc., and omission of image information. CONSTITUTION: An NTSC signal s1 is separated to RGB and converted to a digital signal by an A/D converter 4. The signal is inputted to a shift register 14 or 15 by a changeover switch 13 switched synchronizing with a switching signal s10, and after it is converted to the parallel data in synchronism with a shift clock 18 and stored in one line memories 16, 17. This data correspond to phosphors R, G, B arranged on a panel 29, e.g. the data equivalent to G11, G12,...R1480 of a first row and the data equivalent to B21, G22,...G2480 of a second row are obtained from the signal of a first line, and they are displayed. Similarly, the data of the second row and the third row of the panel are obtained from the signal of a second line, and the second row is displayed repeatedly by the signal of the first line and the signal of the second line. Thus, an image becomes the state where an LPF is applied in human visual sense, and it is realized by a simple circuit. |
