  • Patent number: 10369746
    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: 9942419
    Abstract: An image forming apparatus includes a forming unit, a detecting unit, and a creating unit. The forming unit forms a first image and at least one of second and third images on a recording medium. The first image is used to create correction data for gradation correction. The second image is used to detect a streak in a cross direction which is produced in the first image. The cross direction intersects a conveying direction in which the recording medium is conveyed. The third image is used to detect the streak in the conveying direction which is produced in the first image. The detecting unit detects the streak by using at least one of the second and third images. When the detecting unit detects the streak, the creating unit creates the correction data on the basis of a portion other than a region corresponding to the streak in the first image.
