<p>PURPOSE:To obtain the titled filter having a good color reproducibility and color balance by composing the 1st and the 2nd lines of a color constitution of the repetition of magenta and green and the 3rd and the 4th lines of a color constitution of the repetition of green and yellow respectively, and by forming the green with overlapping cyan and yellow and by forming the blue color with overlapping magenta and cyan respectively. CONSTITUTION:The titled filter is composed of the repetition of the four lines using the 3 kinds of the coloring matters comprising magenta, cyan and yellow, and the 1st and 2nd lines of said filter are composed of the repetition of magenta Mg. and green G, and the 3rd and the 4th lines are composed of the repetition of yellow Ye and blue B respectively. Thus, the green is formed by overlapping cyan and yellow and the blue is formed by overlapping cyan and magenta. As a video signal, luminance signals Yn [(n) line] and Y(n+1) (n+1 line) of the 1st and the 2nd fields are the same to each other, and are Yn=Mg+G, and Y(n+1)=B+Ye, respectively. The spectacle characteristics of each colors are adjusted in such a way that the shading of the line is quiet in a visible range (a wavelength of 400-700nm), whereby the shading of the line becomes quiet, and the balance of colors are improved.</p> |
