    • 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.
    • 执行图像的边缘增强处理的图像处理装置包括获取单元,计算单元,设置单元和处理单元。 获取单元获取由与主扫描方向垂直的主扫描方向和副扫描方向对齐的像素构成的图像数据。 计算单元获得图像的边缘方向和指示亮度值的变化幅度的变化量。 设定单元设定边缘增强处理的强度。 处理单元执行边缘增强处理。 在副扫描方向上的图像数据分辨率高于主扫描方向的情况下,设定单元将边缘增强处理的强度设定为边缘方向为副扫描方向时的高度 比边缘方向为主扫描方向。

    • Image processing apparatus and image processing method for formation of high quality image by high-speed error diffusion processing by execution of more complicated threshold condition processing in a simple manner. 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.
    • 通过以简单的方式执行更复杂的阈值条件处理,通过高速误差扩散处理形成高质量图像的图像处理装置和图像处理方法。 当对具有多个浓度分量的多值图像数据执行误差扩散处理并且输出处理结果时,在对多个浓度分量中的第一密度分量执行误差扩散处理时,确定在误差扩散处理中使用的阈值 基于第二密度分量的密度值,然后基于所确定的阈值对第一密度分量执行误差扩散处理,并且输出误差扩散处理的执行结果。 此外,在对多个密度分量中的第二密度分量执行误差扩散处理之后,基于第一密度分量的密度值来确定误差扩散处理中使用的阈值,然后进行误差扩散处理 输出基于所确定的阈值的第二密度分量和误差扩散处理的结果。
