<p>An image transmission apparatus includes a color codec section (108) for performing color image coding of a color image, a run-length codec section (109) for performing run-length coding of a monochrome image, and a switching unit (110) for arbitrarily switching the codec sections (108,109) and to perform coding in units of pages in one communication cycle depending on whether each page is a color image or a monochrome image. Whether each page is constituted by a color image or a monochrome image is set in advance, and corresponding information is stored in a memory (105). Coding is performed by a coding scheme set for each page, and the coded data is transmitted. Alternatively, coded data obtained by both the codec sections (108,109) are stored in a hard disk (107) and the data coded by a coding scheme, which an apparatus (300) at the other end of a communication line can handle, is read out and transmitted. <IMAGE></p> |
