摘要： PROBLEM TO BE SOLVED: To suppress blurring of an outline part of line images in an image in which regions expressing natural images and regions expressing line images are mixed. SOLUTION: Black region extraction data for expressing black regions in which a pixel color is black is generated according to multi-gradation image data, and at the same time, at least a part of pixels for forming outlines of the black regions is extracted according to the black region extraction data. Printing data is adjusted so that an ink amount of black ink dots to be formed to the extracted pixels is reduced. Accordingly, blurring due to bleeding of ink which is brought about to the outline part of line images can be suppressed without extraordinarily degrading the image quality of natural images in the image in which regions expressing line images such as a text or an illustration having a black pixel color and regions expressing natural images are mixed.
摘要翻译：要解决的问题：抑制表示自然图像和表示线图像的区域的区域混合的图像中的线图像的轮廓部分的模糊。解决方案：根据多灰度级图像数据生成用于表示黑色区域的黑色区域的黑色区域提取数据，并且同时根据多灰度级图像数据提取用于形成黑色区域轮廓的至少一部分像素黑色区域提取数据。调整打印数据，使得对提取的像素形成的黑色墨点的墨量减少。因此，可以抑制由于导致线图像的轮廓部分的墨的渗色引起的模糊，而不会使表示例如具有黑色的文本或图示的线图像的区域的图像中的自然图像的图像质量异常降低像素颜色和表示自然图像的区域是混合的。

摘要： PROBLEM TO BE SOLVED: To provide a recorder for properly correcting recording timing along a main scanning direction with respect to a target, and a method of correcting the recording timing. SOLUTION: This recorder includes a PF motor for conveying a paper sheet 38 along the sub-scanning direction Y, a recording head 35 for conducting printing on the paper sheet 38 while repetition-moving in the first direction and the second direction along a main scanning direction X, and a control part for controlling a driving state of the PF motor and the recording head 35, to form correction patterns A-F on the paper sheet 38, and for correcting a relative positional displacement amount when moved in the first direction and the second direction by the recording head 35, based on the correction pattern C obtained based on the first positional displacement amount between the first pattern 52 formed while moving along the first direction, and the second pattern 53 formed while moving along the second direction, and based on the correction pattern E obtained based on the second positional displacement amount between the third pattern 54 formed while moving along the first direction, and the second pattern 53.
