  • Publication number: 20180009169
    Abstract: A three-dimensional data generation device includes a data division unit, a detection unit, an output command unit, and a data correction unit. The data division unit divides sectional shape data on one layer of a shaped object into mark data for shaping a mark for correction of sectional shape data on a different layer to be output as superposed on the one layer and post-removal data obtained by removing the mark data from the sectional shape data on the one layer. The detection unit detects an amount of misregistration of the mark output using the mark data from a position determined in advance. The output command unit commands output using the post-removal data so as to form the one layer of the shaped object together with the mark. The data correction unit corrects the sectional shape data on the different layer using the amount of misregistration of the detected mark.

  • Patent number: 9122978
    Abstract: An image processing device includes an accepting unit, and a conversion information generating unit. The accepting unit accepts items of read data in a device-dependent color space that are generated by reading color patches, items of reference data in a device-independent color space of the color patches, and items of specific color component data each indicating a specific color component in a corresponding one of the color patches. The conversion information generating unit generates conversion information reflecting the presence or amount of a specific color component included in each color patch as information for converting input data in the device-dependent color space to output data in the device-independent color space, on the basis of the items of read data, the items of reference data, and the items of specific color component data.
