摘要： An image of an original document supplied from a scanner portion or the like is, in an attribute-determining portion, subjected to a process for determining whether each pixel is a character pixel or a picture pixel. Thus, separating information is transmitted to a two-layer separating portion and transmitted to a resolution converting portion as data of a separating information plane. The two-layer separating portion separates the image of the original document into a character information plane and a picture information plane in accordance with separating information. The resolution converting portion has a plurality of resolution converting methods. In accordance with transmission attribute information supplied from outside, a transmission-attribute-information recognizing portion selects a resolution converting method independently for each plane. The resolution converting portion uses the selected resolution converting method to subject each plane to the resolution converting process. Each plane submitted to the resolution conversion is formatted in an image-format-lapping portion so as to be transmitted from a transmitting portion through a network.
摘要翻译：在属性确定部分中，从扫描仪部分等提供的原始文档的图像经受用于确定每个像素是字符像素还是图像像素的处理。因此，分离信息被发送到两层分离部分，并作为分离信息平面的数据传送到分辨率转换部分。两层分离部分根据分离信息将原始文档的图像分离成字符信息平面和图像信息平面。分辨率转换部分具有多个分辨率转换方法。根据从外部提供的传输属性信息，传输属性信息识别部分针对每个平面独立地选择分辨率转换方法。分辨率转换部分使用所选择的分辨率转换方法来对每个平面进行分辨率转换处理。提交到分辨率转换的每个平面被格式化为图像格式研磨部分，以便通过网络从发送部分发送。
