Abstract
An image forming apparatus is provided which includes an input unit to receive an input image; an area determination unit to divide the input image into a plurality of areas, to compute a weight for at least one of a position, a density and a color of each of the plurality of divided areas and to determine an area on which a copy prevention pattern is to be superimposed among the plurality of divided areas; a generation unit to superimpose the copy prevention pattern on the determined area of the input image and to generate a copy prevention image; and an output unit to output the generated copy prevention image. Therefore, it is possible to select a position of a document into which the copy prevention pattern is to be inserted.
Claims31
An image forming apparatus, comprising:
- an input unit to receive an input image;
- an area determination unit to divide the input image into a plurality of areas computing a weight for at least one characteristic of each of the plurality of divided areas and to determine an area on which a copy prevention pattern is to be superimposed among the plurality of divided areas based on the computed weight;
- a generation unit to superimpose the copy prevention pattern on the determined area of the input image and to generate a copy prevention image;
- and
- an output unit to output the generated copy prevention image.
An image processing method of an image forming apparatus, the method comprising:
- receiving an input image;
- dividing the input image into a plurality of areas, computing a weight for at least one characteristic of each of the plurality of divided areas and determining an area on which a copy prevention pattern is to be superimposed among the plurality of divided areas, at an area determination unit, based on the computed weight;
- superimposing the copy prevention pattern on the determined area of the input image and generating a copy prevention image;
- and
- outputting the generated copy prevention image.
An image forming apparatus, comprising:
- an input unit to receive an input image;
- an area determination unit to divide the input image into a plurality of areas, to compute a weight for at least one of a position, a density and a color of each of the plurality of divided areas when a user command to determine an area on which a money notes copy prevention pattern is to be superimposed is not received and determining an area on which the money notes copy prevention pattern is to be superimposed among the plurality of divided areas based on the computed weight when the user command is not received;
- a generation unit to superimpose the money notes copy prevention pattern on the determined area of the input image and to generate a copy prevention image;
- and
- an output unit to output the generated copy prevention image.
An image forming apparatus, comprising:
- an input unit to receive an input image;
- an area determination unit to determine an area of the input image on which a money notes copy prevention pattern is to be superimposed based on a user input by scrolling through portions of the input image;
- a generation unit to superimpose the money notes copy prevention pattern on the determined area of the input image and to generate a copy prevention image;
- and
- an output unit to output the generated copy prevention image.
