<p>PURPOSE:To obtain satisfactory color reproducibility irrespective of a color temperature and the kind of a light source, and also, by a simple signal processing. CONSTITUTION:A flattened film 4 consisting of a thermosetting acryl resin is formed on the whole surface containing a laminated film 3, and thereafter, on the flattened film 4, an Mg filter (having the maximum absorption in 500-500nm wavelength), a Cy filter (having the maximum absorption in 620-680nm wavelength), and a Ye filter (having the maximum absorption in 420-460nm wavelength) are formed in laminated layer. A G filter is formed by laminating the Cy filter and the Ye filter. Subsequently, this element is constituted by forming a correction filter 6 (having the maximum absorption in 470-510nm wavelength) only on the Cy filter. In addition the thickness of Ye filter is thinner than the film thickness used useally, and for instance, formed to film thickness to satisfy that a slope on a short wavelength side is shifted to a short wavelength side by 20nm maximum, when the Ye filter is converted by spectral sensitivity characteristic. Also, relative sensitivity in a wavelength area in which spectral sensitivity characteristic curves of green and blue are superposed to each other is set to <=50%.</p> |
