Abstract:
1. A communication control method in a facsimile apparatus that is capable of communicating color information, comprising the steps of: receiving, in a preliminary procedure, notification information from a receiving machine, the notification information indicating whether the receiving machine has a function for receiving JPEG-encoded information in Lab color space, whether it has a function for receiving full-color information in Lab color space, and whether it has a function for receiving JPEG-encoded information in sYCC color space; notifying the receiving machine of an image to be transmitted being JPEG-encoded in Lab color space, full-color information in Lab color space, or JPEG-encoded information in sYCC color space; and if a JPEG file in sYCC color space stored on a removable storage medium has been specified as an image to be transmitted, transmitting an image in sYCC color space that has been stored on the removable storage medium to the receiving machine as a file on the condition that the received notification information indicates the existence of the function for receiving JPEG-encoded information in sYCC color space, if a plurality of JPEG files in sYCC color space stored on the removable storage medium have been selected as image files to be transmitted, transmitting a PPS-MPS signal at a timing between successive image files to be transmitted, irrespective of the number of pixels in the main-scan direction in respective image file information, and then transmitting a subsequence image file without performing a pre-procedure for the subsequent image file, and if a plurality of document images in Lab color space are transmitted, transmitting a PPS-EOM signal depending on a change of the number of pixels in the main-scan direction between a document image having just been transmitted and a subsequent document image to be transmitted, and then transmitting the subsequent document image after performing the pre-procedure for the subsequent document image, while transmitting a PPS-MPS signal if there is no change in the number of pixels in the main-scan direction between the document image having just been transmitted and the subsequent document image to be transmitted, and then transmitting the subsequent document image without performing the pre-procedure for the subsequent document image.
