Abstract: A reference pixel PB is specified for a specified pixel P0 whose (luminance) value is below a threshold, for example, in the RGB data obtained in image pickup. The reference pixel PB should be on a straight line passing through the specified pixel P0 and the center O of the image and spaced from the specified pixel P0 by a distance, dr, depending on a reduction or expansion rate of a blue component (or B) image of the optical image corresponding to an optical zoom magnification in the image pickup. Only when the B value of the specified pixel P0 is greater than that of the reference pixel PB, the B value of the specified pixel P0 is replaced with that of the reference pixel PB. By expanding or reducing the blue component image alone for the original RGB data, image data is obtained in which the magnification chromatism is corrected.

Abstract: What is disclosed is a novel system and method for implementing a color model function for a printer that uses a relatively large number of colorants. The model is based upon several four color printer color models that contain more complete color models by storing output data for a higher number of input color value combinations and a small number of additional measurements that characterize the response of the printer to outputs using more than four colorants. Results from more complete printer models are determined and combined with a CMYKOV printer model that stores output values for only a coarse resolution of inputs. Transitions between various regions of color space defined by the colorant model definitions are then smoothed. A higher dimension printer color model output is produced. The present method effectively determines a higher dimension color printer model output corresponding to values of an N+2 dimension color model input.

The expendable amount deriving unit derives the amount of the expendable item in accordance with a size of an image printed by the printer. The expendable amount storing control unit stores information representing the amount of the expendable item derived by the expendable amount deriving unit in a memory unit.

Abstract: A system is provided for supporting multiple platforms with common personal preferences for printer drivers. The set preferences for the printer driver are therefore reusable and may be moved from one driver to another. The system involves the provision of a common format for printer driver preferences. When a new printer is brought to a system or a user moves to a station that uses a different printer, the preferences are readily moved to that location. Further, an MIS department may provide a corporate wide printer preference solution, for example for printing a particular page or printing in a particular style. The preferences may not be identical for each printer due to differences in the capabilities of various platforms. The printer preferences overwrite a default value in printers with preferences, to the extent that each printer has the options available. To the extent that these options are not available, the printer reverts to its default setting.
