Abstract
Provided is an image communication apparatus which, if encoded image information is received, controls the form in which the received image information is printed in dependence upon whether a specific type of printing paper has been loaded or in dependence upon whether color-space information of the received image information matches a prescribed color space.
Claims22
An image communication apparatus capable of communicating color image information, comprising:
- a first notifying unit for notifying the transmitting machine of whether this communication apparatus has a function for receiving JPEG code information in Lab color space;
- a second notifying unit for notifying a transmitting machine of whether this communication apparatus has a function for receiving full-color information in Lab color space;
- a third notifying unit for notifying the transmitting machine of whether this communication apparatus has a function for receiving JPEG code information in sYCC color space;
- a discriminating unit for discriminating type of printing paper that has been loaded in a printing unit;
- and
- a control unit which, if the JPEG code information is transmitted from the transmitting machine, is for controlling printing of the received JPEG code information by the printing unit in dependence upon whether said discriminating unit has discriminated that a specific type of printing paper has been loaded.
A method of controlling an image communication apparatus capable of communicating color image information, comprising:
- a step of notifying the transmitting machine of whether this communication apparatus has a function for receiving JPEG code information in Lab color space;
- a step of notifying a transmitting machine of whether this communication apparatus has a function for receiving full-color information in Lab color space;
- a step of notifying the transmitting machine of whether this communication apparatus has a function for receiving JPEG code information in sYCC color space;
- a discriminating step of discriminating type of printing paper that has been loaded in a printing unit;
- and
- a control step which, if the JPEG code information is transmitted from the transmitting machine, is a step of controlling printing of the received JPEG code information by the printing unit in dependence upon whether it has been discriminated at said discriminating step that a specific type of printing paper has been loaded.
An image communication method for communicating color image information between a transmit-side apparatus and a receive-side apparatus, said method comprising the following steps executed at said receive-side apparatus:
- a color-space information receiving step of receiving color-space information of an image file transmitted from said transmit-side apparatus;
- a printing method decision step of deciding a method of printing the received image file based upon the color-space information;
- and
- a printing step of printing the received image file by the printing method decided.
An image communication apparatus for receiving color image information from a connected apparatus of a communicating party, comprising:
- a color-space information receiving unit for receiving color-space information of an image file transmitted from the apparatus of a communicating party;
- a printing method decision unit for deciding a method of printing the received image file based upon the color-space information;
- and
- a printing unit for printing the received image file by the printing method decided.
