Embodiment Construction

[0022] Next, an image processing device according to an embodiment of the present invention will be described with reference to the drawings.

[0023] figure 1 It is a configuration diagram of the image processing device 1 of the present embodiment. The image processing device 1 of the present embodiment includes a scanner unit 20 , a printer unit 30 , an operation panel 40 , and a control unit 50 .

[0024] The image processing device 1 includes a processor (not shown), a memory, and the like, and executes a predetermined computer program to realize each component or function of the control unit 50 described below. All or part of the program can be stored in a predetermined recording medium and distributed, or can be transmitted via a network.

[0025] The scanning unit 20 reads an image of a document to obtain image data (scanned image data) of the image of the document. For example, the image processing apparatus 1 may have a document table (not shown), and the scanning ...

Abstract

The invention relates to an image processing apparatus, a method, and a computer program, which are used for enhancing the readability of the watermark characters in the watermark character synthesis copy. An overlap determining unit 510 determines whether or not it is difficult to read watermark characters by overlap between the watermark characters of the watermark image and pixels having a pixel value of the scan image equal to or more than a predetermined value using image data of a watermark image and image data of a scan image read by a scanner unit 20 when the watermark image and the scan image area overlapped. A watermark image generating unit 503 generates a correction watermark image obtained by correcting the watermark image to improve readability of the watermark characters when it is determined that it is difficult to read the watermark characters. A synthesis image generating unit 508 generates a synthesis image in which the correction watermark image and the scan image are overlapped. A printer unit 30 forms the synthesis image on a printing medium.

Description

technical field [0001] The present invention relates to composite copying of watermark characters in which watermark characters are superimposed and printed on an original image, and particularly relates to a technique for making watermark characters easily recognizable. Background technique [0002] When copying a document, there is a watermark character composite copy in which a watermark character not included in the original document is superimposed on a printed copy (for example, Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2007-94620 [0004] In conventional watermark character composite copying, a user designates a position of a composite watermark character at the start of copying, arranges the watermark character at the position, prints a composite image, and performs copying. In this case, the watermark characters may overlap with the characters in the document, making it difficult to recognize. In the case of a document having mu...
