Facsimile machine having resolution compatible with data terminal device

摘要

The facsimile machine connected with a personal computer such that it can send image data to the personal computer. The facsimile machine first requests the personal computer to supply data about communication capability of the personal computer such as resolution mode (scanning line density) and coding method to the personal computer. Upon this request, the personal computer outputs necessary data to the facsimile machine. If a user of the facsimile machine sets to scan the image at a resolution finer than a resolution of the personal computer, then resolution is automatically changed to a rougher resolution to conform with the personal computer. The facsimile machine then scans the image at the modified resolution. The scanned image is coded by the same coding method as the personal computer. The image scanned and coded in line with the communication capability of the personal computer is then stored in a memory and transmitted to the personal computer from the memory.
