Abstract: An image processing apparatus for generating dot data to form an image by forming dots on a recording medium includes a receiving unit, a first, second, and third generating unit, and a correcting unit. The receiving unit receives first and second image data included in image data. The first generating unit generates, per the first image data, first ink color data representing a multi-valued signal value corresponding to an ink color. The second generating unit generates, per the second image data, second ink color data representing a multi-valued signal value corresponding to an ink color. The correcting unit corrects the signal value represented by the generated first and second ink color data. The third generating unit generates, per the first and second ink color data of which the signal values have been corrected, the dot data representing existence of formation of dots to form an image.

Abstract: As viewed for each processing unit in head shading (HS) processing, a processing unit width is more than one pixel, so that a threshold arrangement corresponding to a target quality of an image intended by a dither matrix is kept while a possibility of avoiding zero dots from being generated can be enhanced. Moreover, the threshold arrangement is kept while a possibility of generating the same number of dots in processing units can be enhanced. Consequently, the threshold arrangement corresponding to a predetermined target quality of an image intended by a dither matrix is kept while it is possible to reduce occurrence of uneven density caused by the HS processing. Thus, it is possible to prevent the threshold arrangement from being limited by the HS processing according to the degree of the reduction.
Abstract translation: 如在头部阴影（HS）处理中为每个处理单元所看到的，处理单元宽度大于一个像素，从而保持与由抖动矩阵预期的图像的目标质量相对应的阈值排列，同时避免零 可以增强生成的点。 此外，保持阈值布置，同时可以提高在处理单元中产生相同数量的点的可能性。 因此，保持对应于由抖动矩阵预期的图像的预定目标质量的阈值排列，同时可以减少由HS处理引起的不均匀浓度的发生。 因此，可以防止阈值布置受到根据减少程度的HS处理的限制。

Abstract: When an input image is shifted by 640 pixels from a test pattern with reference to the position of a nozzle, the remainder is obtained by dividing 640 pixels by pixels of the dither matrix in an x direction. For example, when the size of the dither matrix in the x direction is 256 pixels, the dither matrix is shifted by 128 pixels in a direction reverse to the x direction. In this manner, the phase of the dither matrix at the time of the quantization during test pattern printing matches the phase of the dither matrix at the time of the quantization during input image printing. Consequently, unevenness of the dither matrix at a position N becomes the same in both of the test pattern and the input image. The HS correction to density unevenness caused by the unevenness of the dither matrix becomes suitable for the input image.
Abstract translation: 当输入图像相对于喷嘴的位置从测试图案偏移了640个像素时，通过在x方向上划分抖动矩阵的640个像素来获得剩余部分。 例如，当x方向上的抖动矩阵的大小为256像素时，抖动矩阵沿与x方向相反的方向偏移128像素。 以这种方式，在测试图案打印期间的量化时的抖动矩阵的相位匹配输入图像打印期间的量化时的抖动矩阵的相位。 因此，在位置N处的抖动矩阵的不均匀性在测试图案和输入图像两者中都是相同的。 由抖动矩阵的不均匀度引起的对浓度不均匀性的HS校正变得适合于输入图像。
