  • Patent number: 9576342
    Abstract: An image processing apparatus includes an acquiring unit, an identifying unit, and a correcting unit. The acquiring unit acquires input data including shape data on a concave-convex area having a convex part and a concave part and image data of an image formed on the concave-convex area. The identifying unit identifies an uneven area which is within a bottom surface of the concave part and is continuous with a wall surface connecting the bottom surface and a convex surface of the convex part. The correcting unit corrects the image data so that the brightness of a first image area in the uneven area stacked with multiple dots and the brightness of a second image area continuous with the first image area become about the same.

  • Patent number: 9227395
    Abstract: An image processing apparatus includes an acquiring unit, a first calculating unit, a setting unit, a second calculating unit, a first generating unit, and a second generating unit. The acquiring unit acquires image data of an image to be formed by a recording unit using an inkjet system. The first calculating unit calculates a thickness of ejected ink for each pixel based on the image data. The setting unit sets a target thickness of the image. The second calculating unit calculates a difference between the target thickness and the thickness of ink for each pixel. The first generating unit generates complementary data, in which an ejection amount of an additional droplet to realize a thickness corresponding to the difference is defined for each pixel. The second generating unit generates print data containing the image data and the complementary data.
