Image information communication apparatus, image processing apparatus, and storage medium

An image processing apparatus comprising:

• an image processing unit configured to perform predetermined image processing;
• a communication unit configured to communicate image information with an external device in response to receiving a communication request;
• a permission unit configured to permit the communication request on the basis of a result of comparison between a total band and an overall band, the total band being obtained by adding a communication band necessary for requested communication in the case where the communication unit receives the communication request and a band being used for other communications, and the overall band being obtained by converting an image processing capability of the apparatus into a band;
• and
• a controller configured to control the communication unit so as to communicate with the external device for the request permitted by the permission unit,
• wherein the permission unit is configured to acquire the communication band on the basis of a protocol matching a communication network requested by the communication request,
• wherein the permission unit is configured to compare a value obtained by subtracting a converted value from the overall band and the total band, the converted value being obtained by converting image processing being executed by the image processing unit into a band,
• wherein the image processing apparatus is configured for facsimile communication.
