Abstract
An image processing apparatus includes an information acquiring portion that acquires information on image process conditions for processing image data, a creating portion that creates additional image data, serving as a watermark image, with additional information to be embedded into the image data on the basis of the information on the image process conditions acquired, and a merging portion that merges the image data with the additional image data to create composite image data.
Claims6
An image processing apparatus comprising:
- an information acquiring portion that acquires setting information of a printer driver on image process conditions for processing image data, the setting information including information on an angle of a screen lattice used for pseudo-tone processing;
- a creating portion that creates additional image data, serving as a watermark image, to be embedded into the image data based on the acquired information on the image process conditions and additional information;
- and
- a merging portion that merges the image data with the additional image data to create composite image data, wherein the creating portion creates a pattern image of an integral multiple of a screen shape, which is converted from a rectangular shape to a parallelogram shape by an affine process;
- wherein the pattern image has a size adjusted according to a print resolution and wherein the merging portion selects pattern images corresponding to the additional information and arranges multiple pattern images in a given order.
An image processing method comprising:
- acquiring setting information of a printer driver on image process conditions for processing image data, the setting information including information on an angle of a screen lattice of a screen used for pseudo-tone processing;
- creating additional image data, serving as a watermark image, to be embedded into the image data based on the acquired information on the image process conditions and additional information;
- converting the screen from a rectangular shape to a parallelogram shape by an affine process;
- merging the image data with the additional image data to create composite image data;
- and outputting the composite image data to the printer, wherein the created additional image data is a pattern image of an integral multiple of a screen shape;
- wherein the pattern image has a size adjusted according to a print resolution and selecting pattern images corresponding to the additional information and arranging multiple pattern images in a given order.
A non-transitory computer-readable medium encoded with instructions capable of being executed by a computer to perform image processing, the image processing comprising:
- acquiring setting information of a printer driver on image process conditions for processing image data, the setting information including information on an angle of a screen lattice of a screen used for pseudo-tone processing;
- creating additional image data, serving as a watermark image, to be embedded into the image data based on the acquired information on the image process conditions and additional information;
- converting the screen shape from a rectangular shape to a parallelogram shape by an affine process;
- merging the image data with the additional image data to create composite image data;
- and outputting the composite image data to the printer, wherein the created additional image data is a pattern image of an integral multiple of a screen shape;
- wherein the pattern image has a size adjusted according to a print resolution and selecting pattern images corresponding to the additional information and arranging multiple pattern images in a given order.
