Abstract: An image processing apparatus includes an adjustment unit, an acquisition unit, and a forming unit. The adjustment unit is configured to adjust an output value corresponding to an input value including a predetermined value in a first lookup table storing the output value corresponding to the input value. The acquisition unit is configured to acquire a second lookup table by adjusting the first lookup table through adjustment of the output value by the adjustment unit. The forming unit is configured to form an image using color-adjusted image data generated by performing color adjustment on image data to be processed using a color conversion table generated based on the second lookup table acquired by the acquisition unit.

Abstract: An application amount of developer on a printing medium on which a page that is to be processed has been formed is obtained based on image data that includes a plurality of pages, and based on the image data, a coverage ratio of the developer on a printing medium on which a predetermined page has been formed is obtained. Then, setting temperatures of the heater that respectively correspond to the application amount and the coverage ratio are obtained, and the temperature of the heater is controlled based on the measured actual temperature of the heater and the obtained setting temperatures of the heater, thereby performing control to subject the printing medium on which the page that is to be processed has been formed to fixing.

Abstract: The prior art has such a problem that image quality degrades because dots are conspicuous in the case where the size of each dot is not so small and the black or white dots are regularly aligned, in particular, in a bright part close to white or in a dark part close to black. It is determined whether a black or white pixel exists at a point-symmetric position with respect to a notice pixel using pattern matching for a binarized image and in the case where a pixel exists at the point-symmetric position, the notice pixel is replaced with a specific output pattern.

Abstract: In the event that the printing operations of a printing job have been interrupted by an interruption cause, and the cause of interruption for the interruption job is removed, resuming of the printing operations of the interrupted job is enabled with a resuming method corresponding to a user request, received from a user via a user interface, for a selection option that has been selected from multiple selection operations relating to resuming methods of the printing operations. This enables job resuming processing of a job regarding which printing has been interrupted to be suitably executed even under a printing environment such as a POD environment.

Abstract: The present invention provides an Image processing apparatus, etc. by which a user is able to set which of graphics, etc. and characters are enlarged to be printed on a priority basis. An image processing apparatus according to an embodiment of the present invention includes the steps of separating a character object from a graphic object included in an image and adjusting sizes of the character object and the graphic object according to a priority of an object designated by a user. The adjusting step enlarges the size of a high-priority object and reduces the size of a low-priority object. Furthermore, the adjusting step includes the step of automatically adjusting the sizes of the character object and the graphic object.
