摘要： PROBLEM TO BE SOLVED: To enable suppression of an increased memory capacity in an image processing device, with a configuration having mutual correlation in the distribution of a multi-valued data. SOLUTION: Quantization processing is performed for data distributed by color (S104). Binary data obtained by the quantization processing is selected, only for the color that generates recording amount information (S106). Then, regarding the binary data of the selected color, the recording amount information is generated after filtering processing is performed (S107). In the quantization processing for a second plane, a value converted into a negative value from the recording amount information generated in the first plane processing is added to the multi-valued data. In the quantization of the second plane, after this addition, the value of the multi-valued data is decreased, and the probability of producing binary data for dot recording is decreased in the quantization. Namely, the proportion of overlaid dot formation between the first plane and the second plane can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：为了能够抑制图像处理装置中增加的存储容量，具有在多值数据的分布中具有相互关联的配置。解决方案：对颜色分布的数据进行量化处理（S104）。仅针对生成记录量信息的颜色选择通过量化处理获得的二进制数据（S106）。然后，关于选择的颜色的二进制数据，在执行滤波处理之后生成记录量信息（S107）。在第二平面的量化处理中，将从第一平面处理中生成的记录量信息转换为负值的值加到多值数据。在第二平面的量化中，在该加法之后，多值数据的值减小，并且在量化中产生用于点记录的二进制数据的概率降低。即，可以减少第一平面与第二平面之间的重叠点形成的比例。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image processing apparatus capable of simultaneously quantizing a plurality of pixel sequences in simple configuration in accordance with an error diffusion system, without the need to perform complicated timing control.
SOLUTION: An image processing apparatus comprises a first error diffusion means, a second error diffusion means and an error diffusion selection control means. In the first error diffusion means, a quantization error, which is caused when quantizing respective pixels from one end of a pixel sequence to the other end sequentially, is diffused to a non-processed pixel in a processing pixel sequence including a pixel of interest to be quantized and to a pixel positioned more on the side of the other end than the pixel of interest in a pixel sequence adjacent to the processing pixel sequence and including the non-processed pixel. In the second error diffusion means, the quantization error is diffused to the non-processed pixel of the processing pixel sequence including the pixel of interest and a pixel more on the side of the one end than at least the pixel of interest in the pixel sequence adjacent to the processing pixel sequence and including the non-processed pixel. In the error diffusion selection control means, control is performed to quantize the pixels while selecting any one of the first error diffusion means and the second error diffusion means for each pixel sequence.

摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of highly precisely embedding an accurately detectable digital watermark in data, and to provide a control method and a program thereof.
SOLUTION: The position of a poor ejection nozzle is detected (step S801). Next, a non-feasible area to embed the digital watermark is determined based on a detection result obtained at the step S801 (step S802). The non-feasible area to embed the digital watermark means an area wherein the digital watermark is not embedded intentionally in the subsequent processing. In this case, an area scanned by the poor ejection nozzle is included as the non-feasible area to embed the digital watermark. Next, whether or not a line (processing line) to which the digital watermark processing may be performed belongs to the non-feasible area to embed the digital watermark is judged (step S803). The digital watermark embedding processing is performed whenever the processing line does not belong to the non-feasible area to embed the digital watermark (step S804).
