  • Patent number: 9864934
    Abstract: The optical scanning device includes a storage unit configured to store information on a scanning time of laser light and an emitted position of the laser light in a sub-scanning direction, the laser light measured on a plane. A scanning time for forming one scanning line is set based on the information on the measured scanning time and the measured emitted position, which is stored in the storage unit, and a radius of a photosensitive drum. This allows a magnification error in a main scanning direction to be reduced with an inexpensive configuration while realizing downsizing of an apparatus.

  • Patent number: 9860506
    Abstract: This invention converts input color data into output color data using a table which has been created based on spectral data generated by an appropriate generation method and indicates the correspondence between an input chromaticity and an output chromaticity. To do this, an input color data acquisition unit converts input color data into input chromaticity data. An output chromaticity data calculating unit converts the input chromaticity data into output chromaticity data by referring to an LUT indicating the correspondence between an input chromaticity and an output chromaticity. An output color data calculating unit converts the output chromaticity data into output color data using a conversion coefficient calculated from the input color data. The table indicating the correspondence is created based on spectral data generated by a generation method different for each of a low chroma color and a high chroma color.
