Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0027]

[0028] FIG. 1 is a diagram showing an example of the configuration of an image color judging device 1 in the present embodiment. Here, the image color judging device 1 is a scanner, a printer, a copy machine, a facsimile machine, or a multifunction machine combining these functions. In addition, the image color judging device 1 can detect, for example, the background color of the document read by the scanner unit 41 .

[0029] As shown in FIG. 1 , the image color determination device 1 mainly includes a scanner unit 41 , a recording unit 51 , a ground color determination unit 70 , and a target image determination unit 80 . Here, the "underground color" refers to the background color existing in the document.

[0030] The modem 22 converts digital data into a voice signal for transmission, or converts a voice signal received by the image color judg...

Abstract

An image color determining device. A ground color presence detecting section determines the presence of a ground color of a target image based on image data relating to the target image. A ground color region specifying section specifies a ground color region in a color space when it is determined that the ground color is present. The ground color region determining section determines whether or not the image data to be determined is a ground color region based on the specified ground color region. The ground color replacing section replaces the image data determined as the ground color region with a predetermined color.

Description

technical field [0001] The present invention relates to an image color judging device and image color judging method for judging the background color of an object image, and particularly relates to an improvement for removing the background color or replacing the background color with a prescribed color. [0002] This application claims the priority of Japanese Patent Application No. 2006-242192 filed on September 6, 2006, the entire contents of which are incorporated herein. Background technique [0003] An image processing apparatus is known that performs predetermined processing based on the background color or background color of an original. In order to record or transmit an easy-to-read color original, the image processing device reads the front end of the original by the reading unit, judges the background color of the original, and places the part other than the background color of the original on the background. In the case of a darker color, it is replaced with a ...
