Non-transitory storage medium storing instructions executable by communication terminal, communication terminal, and processing apparatus

A communication terminal comprising:

• a display;
• an input device configured to detect an instructed point which is a point on the display and at which an instruction is provided with an input object;
• a communication device configured to communicate with a processing apparatus;
• and
• a controller configured to:
• receive instruction image data from the processing apparatus, the instruction image data being for displaying, on the display, an instruction image for instructing a processing to be executed by the processing apparatus;
• display the instruction image on the display based on the received instruction image data;
• identify an input event on the input device in response to an instruction provided on the input device with the input object in a state in which the instruction image is displayed;
• and
• transmit, to the processing apparatus via the communication device, the identified input event and coordinate information about the instructed point on the display which is detected by the input device in a state in which the instruction image is displayed,
• the coordinate information being based on standard-size positional information and a location of the instructed point on the display regardless of whether a size of an instruction image being displayed on the display is increased or reduced, the standard-size positional information being for indentifying a location of the instructed point when the instruction image is of a standard size,
• control of the controller being achieved by at least one of a software processing and a hardware processing.

A processing apparatus controllable by a communication terminal, the processing apparatus comprising a controller,

• the communication terminal comprising:
• a display;
• an input device configured to detect an instructed point which is a point on the display and at which an instruction is provided with an input object;
• and a communication device configured to communicate with the processing apparatus,
• the communication terminal being configured to, when at least one of a size-increase instruction and a size-reduction instruction for an instruction image which is displayed on the display of the communication terminal and which is for instructing a processing to be executed by the processing apparatus is performed on the input device of the communication terminal, perform a corresponding one of increasing and reducing a size of the instruction image,
• the processing apparatus being configured to:
• transmit, to the communication terminal, instruction image data for displaying the instruction image on the display;
• and
• receive, from the communication terminal, an input event on the input device and coordinate information about the instructed point on the display which is detected by the input device,
• the coordinate information being based on standard-size positional information and a location of the instructed point on the display regardless of whether the size of the instruction image displayed on the display is increased or reduced, the standard-size positional information being for indentifying a location of the instructed point when the instruction image is of a standard size,
• the controller of the processing apparatus being configured to execute a processing based on the received input event and coordinate information as input.
