| 摘要 | An image processing apparatus includes: a line noise detection section for detecting line noise pixels included in input image data; a segmentation process section for determining a pixel in a text region; and a line noise removal process section for (i) determining a replacement-target line noise pixel by excepting, from the line noise pixels, the pixel in the text region and a pixel within a first distance from the pixel in the text region and (ii) replacing the replacement-target line noise pixel with another pixel other than the line noise pixels, which another pixel is included in the input image data. | ||

| 主权项 | 1. An image processing apparatus, comprising: a line noise detection section for detecting line noise pixels included in input image data; a segmentation process section for determining at least a pixel belonging to a text region of the input image data; and a line noise removal process section for (i) determining a replacement-target line noise pixel which is a remaining line noise pixel obtained by excepting, from the line noise pixels, (a) a pixel which has been determined as belonging to the text region and (b) a line noise pixel within a first distance from the pixel determined as belonging to the text region and (ii) replacing the replacement-target line noise pixel with another pixel other than the line noise pixels, which another pixel is included in the input image data. | ||
