Provided is an image processing method and a apparatus of converting a color input image or a partial region thereof in accordance with a color gamut of a color image output apparatus is provided. The method and apparatus is characterized in that only the region requiring color gamut compression can be put to color gamut compression depending on the distribution of an input image, that the direction of the color gamut compression can be controlled continuously for each of the regions; the amount of the color gamut compression can be controlled continuously including clipping, that when color gamut compression is conducted by a color converter of a multi-dimensional DLUT interpolating calculation type, an excessively unnecessary color gamut compression can be avoided particularly upon clipping, and that there is enabled correction for visual bending in iso-hue lines caused by distortion of a color space in each of the regions of the color space.

Image processing method and image processing apparatus

The invention provides an image processing apparatus having a device for inputting image data, a color distribution recognition device for recognizing a color distribution in a color space and position information in an image space of the image data input through the input device, and a device for determining one or more color reproduction parameters of the image data based on the color distribution and position information recognized by the color distribution recognition device and a color reproduction range of an output device.

Image processing apparatus, image processing method, and image processing system

An image processing apparatus is disclosed which includes an input device that inputs image data, a color distribution recognition device that recognizes a color distribution in a color space and position information in an image space of the image data input through the input device, and a device that determines one or more color reproduction parameters of the image data based on the color distribution and position information recognized by the color distribution recognition device and a color reproduction range of an output device.

An image processing apparatus is disclosed which comprises:

Image processing apparatus, image processing method, and image

Data for use in specifying an image to be registered and data indicative of processing contents to be executed are listed in list structure and registered in a 'reference list to image storage unit' and a 'reference list to processing-content storage unit,' respectively. The aggregate area thus listed is subordinated to another aggregate area. When image processing and output are performed and produced, an aggregate area is designated and the processing contents are applied to the image registered in the aggregate area. Even a low-order aggregate area is processed in accordance with the listed contents of the high-order aggregate area.

Image processing apparatus and image attribute altering method

An original image 402, conversion images 404a-404c provided by executing gamut compression systems, and a mix percentage scale 406 are displayed on a display. The user can click on any one of the conversion images 404a-404c for specifying a user-adjusted image 403. Further, when the user clicks on the mix percentage scale 406, the conversion images 404a-404c are mixed in response to the point on which the user clicks (point 406p), and the result is specified as the user-adjusted image 403.

Image processing system

A state transition display window displays a hue circle and a number of setting points corresponding to respective color adjustment levels. As the user makes color adjustments, a history of the color adjustments is displayed in the form of arrows connecting related setting points. If the user specifies two setting points, images corresponding to setting point located on the line connecting the two specified setting points are displayed on an image display subwindow. A current image and six images adjacent thereto are displayed in a 6 near images display window.

Image processing apparatus and method with multi-dimensional display of

A color-image forming apparatus includes: an electrostatic latent image holder; electrostatic latent image forming unit for forming a plurality of electrostatic latent images on the image holder; a scanning unit for scanning the electrostatic latent image holder periodically at predetermined timings; developing devices for developing each of the plurality of electrostatic latent images by toners of each of different colors respectively, and forming thus developed toner image on the image holder; a simultaneously transferring device for simultaneously transferring the plurality of toner images onto a transfer medium; fixing device for fixing the toner image on the transfer medium; and timing-setting unit for setting a timing at which said scanning means starts scanning at each of slow scanning pitches in the direction of fast scanning for each of the plurality of colors; wherein the timings which are allotted to each of the colors are different each other so that the starting position of the scanning of each color at each of slow scanning pitches in the direction of the fast scanning is successively shifted at a predetermined distance.
