Provided is a color compensation method in an image forming apparatus. The color compensation method may include imaging a first color chart by a first image forming apparatus, scanning the imaged first color chart, comparing information regarding the scanned first color chart and information regarding a reference color chart to determine an international color consortium (ICC) profile of the first image forming apparatus, and performing color compensation on the first image forming apparatus based on the determined ICC profile.

Method and device for color compensation

An image forming apparatus is provided. The image forming apparatus includes: a storage configured to store a color conversion table; an image former configured to print a compensation chart corresponding to the color conversion table; a scanner configured to scan the printed compensation chart; and a changer configured to understand a range of brightness that the image former is able to represent using the scanned compensation chart, generate a gamma curve corresponding to the understood range of brightness, and change the color conversion table based on the generated gamma curve.

Image forming apparatus and method for revising color

An image forming apparatus having a toner saving function is disclosed. The image forming apparatus includes a printer configured to perform a printing job, a communicator configured to communicate with a host device, a storage configured to store information of a toner saving option which is differently set to respective data characteristics, and a controller configured to, in response to a print data being received from the host device through the communicator, control the printer to detect characteristics of the print data, and print the print data according to the toner saving option which is set to correspond to the detected characteristics.

Image forming apparatus having toner saving function and method for printing

An image forming apparatus includes a storage unit to store a color conversion table, a user interface unit to receive a color revision initiation command, an image forming unit to print a color chart generated based on the color conversion table if the color revision initiation command is received, the color chart having a plurality of CMYK mixed colors having at least one of brightness and chroma changed, a scan unit to scan the printed color chart, and a change unit to revise the color conversion table using the scanned color chart.

Image forming apparatus and method of color revising

An image revising method, an image forming apparatus, and a method for revising image spreading are provided. The image revising method includes regulating a black color level in a black area of an input image; adjusting a color level of at least one other color excluding the black color in the black area; and revising the image by applying the regulated black color level and the adjusted color level of the at least one other color. Thus, in copying a document, the black color with the enhanced legibility can be serviced.

Image revising method, image forming apparatus and method for revising image spreading

A color conversion method includes determining a race by recognizing a skin region in an input image, selecting a preferred skin color to apply to the skin region based on a plurality of preferred skin color information preset per race, and correcting a color of the skin region using the selected preferred skin color. Additionally, a color conversation apparatus includes a control unit to determine a race by recognizing a skin region in an input image input, and to select a preferred skin color to apply to the skin region, based on the plurality of the preferred skin color information stored in a storage unit, and a compensation unit to correct a color of the skin region using the preferred skin color selected by the control unit. Hence, the skin color per race can be adequately converted to the color which can satisfy the user.

Color conversion apparatus and method thereof

An image forming apparatus includes a user interface, and an image forming unit to perform an image forming job in a new image mode by combining two or more image modes when the two or more image modes are selected through the user interface. The image forming unit may include a controller to combine color lookup tables of the two or more selected image modes and to create a new color lookup table, and an engine unit to perform the image forming job in an image mode corresponding to the new color lookup table. Therefore, it is possible for the image forming apparatus to support various image modes.

Image forming apparatus and method thereof to generate a new image mode by combining selected image modes

An apparatus includes a gray converter to convert an inputted color image to be printed into a gray conversion image and to outputs the gray conversion image a difference calculator to calculate a at least one difference value between at least one color channel image with respect to the color image and the gray conversion image; and a gray reviser to revise the gray conversion image based on the at least one difference value and to output a gray conversion image.

Image forming apparatus and image forming method capable of revising gray image

A service framework which can control devices to be controlled according to a device/service profile by creating the device/service profile to control a plurality of the controlled devices. Accordingly without using a middleware with a complicated structure, it is possible to control home devices.

Service framework for a home network

An image forming apparatus including a scanning unit to scan an image and to output corresponding digital color coordinates; a determining unit to determine a local color gamut including the digital color coordinates, based on a reference matrix computed from a standard color gamut, which includes the local color gamut, and the plurality of digital color coordinates; a matrix selecting unit to select a color conversion matrix that corresponds to the determined local color gamut; and a computing unit to compute LAB color coordinates based on the selected color conversion matrix and the digital color coordinates. A method of color conversion using the image forming apparatus is also provided.

Image forming apparatus and color converting method thereof

Image forming apparatus and method of combining processing modes

An apparatus includes a gray converter to convert an inputted color image to be printed into a gray conversion image and to outputs the gray conversion image a difference calculator to calculate a at least one difference value between a at least one color channel image with respect to the color image and the gray conversion image; and a gray reviser to revise the gray conversion image based on the at least one difference value and to output a gray conversion image.

Disclosed is an apparatus for providing device information via a network and method thereof. A message processing unit processes input and output messages. The information producing unit dynamically produces updated information based on the data stored in the database and provides it in a web document format. The information managing unit manages characteristic information and additional information of a device. The data processing unit processes a transaction of the data stored in the database. The characteristic information and the additional information of the device existing in the home network created in an XML format is converted into a predetermined document structure and stored in the database. Accordingly, the remote users can have different access authority from each other by assuring independence between the domestic devices and the remote devices, and easily use the home network service by providing the device information in a web document format.

Apparatus for providing device information via network and a method thereof

An apparatus and method for managing device information through networks. The apparatus for managing device information through networks includes a polling list for storing polling information including device IP addresses assigned to home devices, polling intervals, and last polling times; a poller for checking the polling list and sending out a polling list listing devices to be polled; and a message processor for generating a polling message based on received registration request messages from the home devices, sending out the polling message verifying whether corresponding devices are activated with reference to the polling list, and updating the polling information stored in the polling list based on a response message with respect to the polling message received from the home devices. As different polling intervals are used with respect to devices existing on a home network, the reliability of device information improves and network traffic reduces.
