An object of the present invention is to reduce influences of showthrough where a copy-forgery-inhibited pattern is visualized after printing. In order to attain the above object, the apparatus of the present invention is provided with determination means for determining whether a setting for printing a copy-forgery-inhibited pattern image in which a character portion is rendered to a minor dot portion on both sides of a sheet is made and control means for controlling so that a warning screen is displayed where the determination means determines that the above setting has been made.

Apparatus including a determination unit, and method and program including a determination step

The present invention provides an information processing apparatus and control method thereof and a storage medium that stores its control program capable of generating a code image with the optimum device in accordance with the amount and/or contents of the information to be encoded, and/or considering the load of the equipment. The information processing apparatus is electrically connected to an image processing apparatus, and includes: a deciding section for deciding on whether to generate a code image by encoding information or to issue a command for causing to generate the code image by encoding the information; and a processing section for generating, when the deciding section decides to generate, the code image by encoding the information and transmitting it to the image processing apparatus, and for transmitting, when the deciding section decides to issue, the command to the image processing apparatus.

Information processing apparatus and control method thereof

The image data with the copy-forgery-inhibited pattern image added and an image area flag signal stored in the hard disk drive are inputted into a thinning filter. A thinning circuit does not perform thinning processing on these pieces of data and outputs the inputted image, as it is. The filter performs processing so that an image of a copy-forgery-inhibited pattern background part may be deleted. A selector selects an image signal not passing through the filter for a latent mark of the copy-forgery-inhibited pattern whose image area flag is set as 'Character,' and select an image signal subjected to the processing by the filter for a copy-forgery-inhibited pattern background part whose image area flag is set as 'Photograph.' By doing so, it is possible to perform low pass processing on only the copy-forgery-inhibited pattern background part and perform processing of making a latent-mark part emerge.

Copy-forgery-inhibited pattern or stamp image combined with image data based on user actions

In a printing process, an image quality identifier is referred to in a packet header of image data. It is determined whether the image quality identifier is '1' or '0', and when the image quality identifier is &#x2018;1&#x2019; indicating a high-quality image, six color printing is set. When the image quality identifier is &#x2018;0&#x2019; indicating a low-quality image, four color printing is set. Thus, six color printing is executed for an image read out by a scanner in the CCD technique while four color printing is executed for an image read out by a scanner in the CIS technique. Accordingly, it can be determined according to a simple standard such as kind of scanner.

Printing information processing device, printing device, printing information processing method and printing system

In an image reading apparatus for reading an original image using a light source containing a plurality of color components, a control pulse for dimming the light source is generated by pulse-width modulation symmetrically with respect to a reference timing (for example, the central position in one storage time or the storage start timing) in one predetermined storage time of a line sensor.

Image reading apparatus, and dimming control method and line sensor layout method therefor

Predetermined additional information is superposed as a dot pattern on image information read by an image scanner, and the image information superposed with the additional information is modulated. The modulated information is demodulated and recorded on a recording medium to perform a series of operations, i.e., to simultaneously satisfy both pattern addition and modulation/demodulation.

To control a light emitted from a fluorescent lamp having phosphors with different afterglow properties for different colors, a center of a lighting control signal for controlling the lighting of the fluorescent lamp is controlled to constantly align with the center of a Hsync period so that despite the variation of the lighting time of the fluorescent lamp, a barycenter of the quantity of light from the fluorescent lamp in the Hsync period almost aligns with the center of the Hsync period to reduce the offset of the barycenter.

Image reading apparatus and control method thereof

A device for controlling the copying of an original includes a discriminator for discriminating a specific original in accordance with the degree of significance of the specific original, when discriminating a plurality of specific originals in forming one image. According to another embodiment, the device includes an inhibitor for inhibiting the copying of a specific original, when a memory or peripheral circuit having the discrimination criteria of the specific original is removed or exchanged, or it is out of order, and making a discrimination of the specific original by the same characteristic data of the specific original, even if the image is input from different input equipment, wherein the correct discrimination is effected based on the color tint distribution of the specific original.

Image processing apparatus and method

An image processing apparatus including an area setting unit for setting an area in an image, an image processing setting unit for setting a desired image processing to each area set by the area setting unit, a calculation unit for calculating an outer frame in accordance with the set area, and a designating unit for a user to designate a color of the outer frame, wherein the image is synthesized with the set outer frame having the designated color, and the synthesized image is displayed.

In an image forming apparatus having a printing function and a copying function, the copying operation can be performed as fast as possible without increasing the costs. An image forming apparatus in which an original image is read out by an image reader unit and a copy image is outputted from an image forming unit is constructed by: a measuring unit for previously counting a necessary time from the start of activation of a light source of the image reader unit to timing when the light source enters a usable state; and a control unit for controlling in a manner such that in the case where the necessary time counted by the measuring unit is shorter than a predetermined time, the image forming unit is activated when the light source is activated or after the elapse of a specified time, and in the case where the necessary time counted by the measuring unit is longer than the predetermined time, the image forming unit is activated after it was detected that the light source of the image reader unit entered the usable state.

Image forming apparatus with controller to activate the image forming unit depending on light source cycle-up time

A plurality of apparatuses can execute an encrypting process on an image signal are connected. The encrypting processes which are executed in those apparatuses are independently performed, so that the connection of an improper apparatus is made impossible and, in this state, a more advanced signal process can be performed, thereby giving no disadvantage to the user. For this purpose, there is disclosed an image processing apparatus comprising a first encrypting circuit for encrypting the image data and supplying to a first apparatus and a second encrypting circuit for encrypting image data and supplying to a second apparatus different from the first apparatus, wherein the first and second encrypting means execute independently the encryption.
