Benefits of technology

The present invention provides an image processing apparatus that can add an additional image to an input image based on the characteristics of the input image. The apparatus can output the image without decreasing productivity and prevent the content of the additional image from being dropped. Additionally, the apparatus can calculate the charge amount accurately, regardless of whether the additional image is a color or black / white image. The apparatus can also convert the characteristics of the additional image to avoid dropping the content of the additional image. These technical effects improve the efficiency and accuracy of image processing.

Problems solved by technology

As a result, there is such a risk that productivity is considerably lowered.
As a consequence, the following problem may occur.
That is, since the image formed for the color image is black / white-converted, certain colors are dropped out, and color differences cannot be discriminated from each other, so that the content of the image cannot be correctly informed.

first embodiment

[0025]FIG. 1 is a block diagram for indicating an image processing apparatus according to the present invention. In this drawing, reference numeral 1 shows an interface unit, reference numeral 2 indicates a color judging unit, reference numeral 3 represents an additional image storage unit, reference numeral 4 shows a color image storage unit, and reference numeral 5 demotes a black / white image storage unit. Also, reference numeral 6 shows an image synthesizing unit, reference numeral 7 indicates an image output unit, and reference numeral 8 is a control unit. The interface unit 1 receives an input image which is transferred outside this image processing apparatus. The input image may be realized by, for example, image data represented by a raster format, and other various data such as image data described by a page description language (will be referred to as a “PDL” hereinafter). The input image is supplied to both the color judging unit 2 and the image synthesizing unit 6.

second embodiment

[0050]Since the above-explained operation of this image processing apparatus is carried out, for instance, as shown in FIGS. 3A and 3B, the color additional image is added with respect to the color input image, whereas the additional image which is converted into the black / white additional image is added with respect to the black / white input image. As a consequence, even when a time duration required to form a color image becomes several times longer than a time duration required to form a black / white image, since the black / white additional image is added to the black / white input image, the additional image can be added, while the productivity is not lowered when the black / white image is outputted. As apparent from the foregoing description, in the case that a time duration required to form a color image is not made different from a time duration required to form a black / white image, as shown in FIGS. 5A and 5B, a color additional image may be added to a black / white input image.

third embodiment

[0053]In this third embodiment, the image synthesizing unit 6 switches one instruction and another instruction in response to a judgment result obtained by the color judging unit 2 as a PDL command by which a color additional image stored in the color image storage unit 4 is added to an input image. In one instruction, such a command for adding a color additional image is added to the input image. In another instruction, such a command for adding a black / white additional image is added to the input image. As a result, for example, when an image described in the PDL format is interpreted in either the image output unit 7 or an externally-provided image forming apparatus, either the color additional image or the black / white input image is added to this input image in response to the PDL command.

[0054]FIG. 9 is a flowchart for describing an example of operations of the above-described image processing apparatus according to the third embodiment of the present invention. In the flow cha...

Abstract

There is provided an image processing apparatus where in an additional image storage unit 3, a color additional image is stored into a color image storage unit 4, and a black / white additional image is stored into a black / white image storage unit 5. A color judging unit 2 judges as to whether an input image corresponds to a color image, or a black / white image every page thereof. Based upon the judgment result of the color judging unit 2, an image synthesizing unit 6 adds the color additional image stored in the color image storage unit 4 to the input image when the input image is the color image, and adds the black / white additional image stored in the black / white image storage unit 5 in the input image when the input image is the black / white image. Then, the image synthesizing unit 6 outputs the resulting image synthesized with the additional image. When the input image is the black / white image, the black / white additional image is added to this input image charge amount for the black / white image can be determined.

Description

[0001]This application is a Reissue of U.S. Pat. No. 7,006,247, issued Feb. 28, 2006, which issued from U.S. application Ser. No. 09 / 716,958, filed Nov. 22, 2000, which claims priority to Japanese Patent Application No. 2000-133635, filed on May 2, 2000.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention is related to an image processing apparatus which may be applied to various sorts of image output systems such as a facsimile, a copying machine, and a printer.[0004]2. Description of the Related Art[0005]Image output apparatuses known as facsimiles, copying machines, and printers are manufactured in composite forms by digitally combining various functions thereof. On the other hand, these image output apparatuses are gradually connectable to networks such as the Internet and an intranet. In addition, data transfer speeds via networks are gradually increased. On the other hand, while hard disks and semiconductor memories are manufactured in low cost...
