发明名称 Imaging apparatus
摘要 An imaging apparatus for reading an image recorded on a photographic film includes: a solid-state imaging device on which an image derived from light transmitted through the photographic film is formed; a density-measuring device for receiving the light transmitted through the photographic film and for measuring a large area transmittance density of the image for each color of R, G, and B; and a correcting device for correcting image color signals on the respective colors of R, G, and B outputted from the solid-state imaging device, on the basis of a ratio of large area transmittance densities of the image for the respective colors of R, G, and B determined from an RGB output of the density-measuring device. Accordingly, since the image color signals on R, G, and B outputted from the solid-state imaging device are corrected in correspondence with the large area transmittance densities of the image for the respective colors of R, G, and B determined from the RGB output of the density-measuring device, it is possible to obtain image color signals having accurate color information irrespective of the spectral sensitivity characteristics of the solid-state imaging device.
