Image processing apparatus, image forming apparatus, information embedding method, and information embedding program

A data sending apparatus, on sending data to a receiving apparatus, searches its storage for a transmission method to the receiving apparatus. After sending data to the receiving apparatus, the sending apparatus receives from the receiving apparatus a transmission result including a transmission condition and capabilities of the receiving apparatus. When an error occurs during the data transmission, the sending apparatus reads the communication and processing capabilities of the receiving apparatus from the transmission result, and resends the data by a transmission method in accordance with the receiving apparatus. It then acquires the transmission result and stores the same in the storage.

Device and method for data transfer

An image editing apparatus capable of accurately registering a texture pattern from a document has the following configuration. The image data of a read document is displayed on a liquid crystal display. A user designates a point C therein and designates a range P for incorporating texture pattern around the point. The user also designates the size and range of the texture pattern used for displaying the texture using cursors S and E so that the texture patterns can be displayed smoothly connected when displayed serially in the vertical and horizontal direction.

Image editing device permitting user to register desired patterns

An image read by an image reader is rendered into binary data and then is stored in a document reading memory. In accordance with the color information provided to the document by a color marker which is stored in the document reading memory, a document image subjected to image processing is displayed on a color LCD. The user can check the color LCD before printing by a printer, such that photocopying by mistake and the like can be prevented.

An image forming apparatus with a plurality of image forming units for forming an input image on a recording medium, a fixing unit for fusing the image formed on the recording medium to the recording medium, a fixing temperature detecting unit for detecting the temperature of the fixing unit, a registration pattern detecting unit for detecting a registration pattern formed by a plurality of image forming units, a calculator for determining a registration correction value for correcting the input image based on output from the registration pattern detecting unit, and an update requesting unit for requesting an update of the registration correction value. The update requesting unit requests an update of the registration correction value based on the temperature detected temperature of the fixing unit.

Image forming apparatus and registration correction method to correct dislocation of formed images

In a digital image forming apparatus wherein a user can change a gradation curve of the density of reproduced image plotted against the input image signal obtained by reading a document, it is needed to compensate a change of color of a reproduced image accompanied by the selection of a changed gradation curve. Then, when input multi-tone image signals of R, G and B are converted to multi-tone image signals of Y, M and C for printing, the masking coefficient used for the conversion from R, G and B to Y, M and C is changed according to the changed gradation curve. Then, the multi-tone image signals of Y, M and C are converted to light quantity data of a beam for exposing a photoconductor to form an image on the photoconductor according to the gradation curve.

Digital image forming apparatus

In marker edition mode, characters such as a character line is read in a closed area on a document marked with a marker. Then, the image data is analyzed to decide image processing means for marker edition such as coloring. A rectangular area including the image is recognized as image processing area. Even if the image is included partially in the closed area marked with a marker, a rectangular area including the image wholly can be specified as image processing area.

Image processor with marker edition mode

An image editing apparatus reads a document image and obtains image data. Thus obtained image data is separately stored as data to be displayed on a display and data for recognizing a closed region in the image. In order to more readily recognize such a closed region, only the latter data is processed without changing the data to be displayed on the display. Thus, an image much easier to view can be displayed on the display.

Image editing device for processing image data

In order to improve operability of a copying machine which applies an image processing to an area of an original surrounded by a marker, following processes are carried out. An area of an original surrounded by a marker is detected. It is determined whether or not the number of the detected areas exceeds 30, or the time from starting of detection exceeds three minutes during the detection. If any of those two conditions is satisfied, edit based on the marker is not executed and image data which has undergone full-color copying is output.

Another image processing device includes a reader for reading an original and outputting image data; a determination device for determining an orientation of the original document read by said reader; a rotater for rotating the image data outputted from the reader on the basis of the direction of said original determined by said determination device; and a display for displaying an original image on the basis of the rotated image data.

Image processing device with original image determination means

In a digital image forming apparatus, a user can select a desired gradation curve representing the relation of the density of reproduced image to the input image signal obtained by reading a document among a plurality of gradation data stored in a memory in correspondence to image forming conditions of an electrophotographic process of forming an image. The image forming condition is determined separately. A gradation correction data is calculated from the gradation data to realize the object gradation curve. Then, an input image signal is converted to light quantity data for a beam for exposing a photoconductor by using the calculated gradation correction data to form a latent image on a photoconductor in the image forming conditions.
