摘要
An image-data transmitter, applicable to a FAX and an image file apparatus, receives image data including a plurality of image-data portions, and identifies the image data for each image-data portion so as to detect a kind of image data for each image-data portion, such as a binary image and a multilevel image. Then the image-data transmitter codes the image data for each image-data portion in accordance with a coding scheme corresponding to the kind of image data of the image-data portion. Thus, a coding efficiency and an image quality of a restored image are not so much degraded.
