摘要： A skew processing circuit 33 includes two line buffers, a skew processing type line buffer 331 and an original type line buffer 332, and a write/read control circuit 333 for controlling the two line buffers. The write/read control circuit 333 is a control circuit for writing a given image data in the line buffers 331, 332 in single lines and selectively reading the data written in the two line buffers 331, 332. When an image data is written in the original type line buffer 332, addressed are sequentially written from the head address 0. On the other hand, when the image data is written in the skew processing type line buffer 331, a write start address RH0 is determined in correspondence with a skew angle, and the write start address RH0 is shifted in each line to discard the head portion of the image data by specified dots (specified addresses). Thus, by controlling the writing of data in the two line buffers 331, 332 and reading data from them, an image in an arbitrary area can be processed into the skew with an arbitrary angle.

摘要： An apparatus for and a method of judging a dotted image area using a small-capacity memory. Image data corresponding to one line out of image data representing an original image are stored in a line memory. On the line corresponding to the image data stored in the line memory, a target pixel is successively set along the main scanning direction. Image data corresponding to the target pixel is compared with image data corresponding to pixels around the target pixel. It is judged whether or not the target pixel is a peculiar point pixel on the basis of the result of the comparison. Further, the distance between peculiar point pixels is operated. The operated distance between the peculiar point pixels is referred to a predetermined judgment basis, to judge whether or not a judging area including the finite number of pixels is a dotted image area.
