摘要： A liquid ejection method involves supplying liquid along a heat generating element disposed along a flow path from upstream of the heat generating element, applying heat generated by the heat generating element to the thus supplied liquid to generate a bubble, thus moving a free end of a movable member having the free end adjacent the ejection outlet side by pressure produced by the bubble, the movable member facing the heat generating element, supplying, to a heat generating element for applying thermal energy to the bubble generating region, a driving pulse divided into a first pulse and an adjacent second pulse with interval time therebetween, pre-heating the liquid by the first pulse to an extent insufficient to eject liquid through the ejection outlet, and generating a bubble by heating the liquid by the second pulse to eject the liquid through the ejection outlet. The method also includes ejecting liquid in an amount determined by controlling a degree of pre-heating of the liquid by changing at least one of a width of the first pulse or the interval time. The change rate of the ejection amount of the liquid increases non-linearly with an increase of the width of the first pulse or an increase of the interval time period. Recording heads and apparatuses control the ejection amount of liquid in like manner.

摘要： There is disclosed an image processing apparatus which determines an attribute of an image including a pixel to be processed. An image area having a predetermined size including the pixel to be processed is extracted (S701). A variation related to the image area is calculated based on pixel values included in the image area (S705). Pixels in the image area are converted into N-ary data (ternary data or higher) in accordance with the calculated variation (S709). The attribute of the pixel to be processed is determined by analyzing the N-ary data as a result of the N-ary conversion (S711).

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.

When error diffusion processing is performed on multivalued image data having plural density components and the result of processing is outputted, upon execution of error diffusion processing on a first density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of a second density component, then the error diffusion processing is performed on the first density component based on the determined threshold value, and the result of execution of the error diffusion processing is outputted. Further, upon execution of the error diffusion processing on the second density component among the plural density components, a threshold value used in the error diffusion processing is determined based on a density value of the first density component, then the error diffusion processing is performed on the second density component based on the determined threshold value, and the result of the error diffusion processing is outputted.

摘要： Upon outputting halftone image data to an output device, density transformation is prevalently performed to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct for color fog and the like that may occur in a photo image. Hence, lightness and color-difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness and color-difference transform amount of the halftone image data is set on the basis of the acquired lightness and color-difference information.
