摘要： A raster image processor (RIP) can process data for one page for each of a plurality of small areas, and handles each individual small area as a display list. Each individual display list holds information required to determine a rendering resolution. The RIP renders a small area including a text object with a high resolution, and a small area which does not include any text object with a low resolution. The RIP renders the respective small areas with the designated resolutions, and temporarily holds the rendering results in a memory for respective small areas. Upon generating a page image, the RIP directly transfers the high-resolution rendering result to a page memory. The RIP transfers the low-resolution rendering result to the page memory with applying an enlarging pixel process to the rendering result.

摘要： An image processing method processes image data to be output to an image forming apparatus that is capable of making a two-way recording to form an image on a recording medium by recording in a forward path and a return path of a scan by an ink-jet recording head. The image processing method includes a halftone process that is based on an inclined line-group keytone and maintains keytone continuity, including a dither process in which the inclined line-group keytone appears at a stage where the recording in the forward path is made.

摘要： An image processing apparatus transfers scan image data acquired by a document reader to an editing apparatus and receives print data based on the scan image data from the editing apparatus. The apparatus includes a first generator generating first attribute data from the scan image data and a second generator generating second attribute data based on the print data received from the editing apparatus. The first and second attribute data indicate an image attribute constituting the scan image data and an image attribute constituting print image data generated based on the print data, respectively. The image processing apparatus further includes a third generator generating third attribute data for each of the pixels constituting the print image data based on attribute information of the corresponding pixel in the first and second attribute data.
