    摘要: An image processing apparatus to perform an edge intensifying processing of an image includes an obtaining unit, a calculating unit, a setting unit, and a processing unit. The obtaining unit obtains image data composed of pixels aligned in a main scanning direction and a sub-scanning direction perpendicular to the main scanning direction. The calculating unit obtains an edge direction of an image and a variation amount indicating a magnitude of change in a luminance value. The setting unit sets an intensity of the edge intensifying processing. The processing unit performs the edge intensifying processing. In a case where the image data resolution in the sub-scanning direction is higher than in the main scanning direction, the setting unit sets the intensity of the edge intensifying processing to an amount that is higher when the edge direction is the sub-scanning direction than when the edge direction is the main scanning direction.

    摘要: This invention allows printing an image with less image deterioration with respect to a document including both text and an image. An image processing apparatus includes a pixel value acquisition unit which acquires a pixel value of a pixel as a target in an input digital image, and a pixel value correction/modification processing unit which executes a correction/modification process based on the pixel value of the pixel acquired by the pixel value acquisition unit. The pixel value correction/modification processing unit includes a contrast correcting unit which executes contrast correction based on information representing a brightness value corresponding to the pixel value of the pixel, and an intermediate color removing unit which removes intermediate color in the digital image by replacing the pixel value of the pixel by pixel values of pixels around that pixel.

    摘要: An increase in energy applied to a heating element can be prevented and the service life of a printhead can be prolonged even when the temperature of the printing element having a negative temperature coefficient rises and the resistance of the heating element decreases. A printhead having heating elements connected to a common power supply comprises a switching element series-connected to and controlling driving of the heating element at a voltage applied to a control terminal; a constant voltage source; a wiring resistance generated at a connection wiring line serial-connected to the heating element; and a voltage control circuit which controls to make the potential difference between both ends of the wiring resistance equal to the voltage of the constant voltage source when driving the heating element. A current flowing through the heating element is made constant without any influence of the temperature.

    摘要: In this invention, to enable printing of an image that has undergone an image process or print process complying with the desire of a user on an image supply device side, real object handles and virtual object handles are set to, of images to be supplied to the printing device, images that require a predetermined image process and remaining images, respectively. A print job including the object handle of a print target image is issued in accordance with a print instruction. If the handle of an image requested by the printing device in response to the issued print job is a virtual object handle, the predetermined image process is executed for image data corresponding to the handle, and the processed image data is supplied to the printing device.
