Abstract

A display device displaying image information transmitted from a main body device on a display, the display device includes: an obtaining unit configured to obtain state information of a monitoring object related to a state of the display device; and a control unit configured to update an update table storing the state information in response to periodically obtaining the state information from the obtaining unit, update state display information for visually displaying the state information stored in the update table, and display the state display information in a state of being superimposed on the image information for a given period.

Claims

1. A display device displaying image information transmitted from a main body device on a display, the display device comprising:

an obtaining unit configured to obtain state information of a monitoring object related to a state of the display device; and

a control unit configured to update an update table storing the state information in response to periodically obtaining the state information from the obtaining unit, update state display information for visually displaying the state information stored in the update table, and display the state display information in a state of being superimposed on the image information for a given period.

2. The device according to claim 1,

wherein there are a plurality of monitoring objects, and

wherein the control unit updates the update table each time state information of one of the plurality of monitoring objects is obtained, and updates a plurality of pieces of state display information for visually displaying a plurality of pieces of state information stored in the update table and displays the plurality of pieces of state display information in a state of being superimposed on the image information for the given period in response to detecting an instruction to display the state display information in a state of being superimposed on the image information.

3. A display control circuit incorporated in a display device displaying image information transmitted from a main body device on a display, the display control circuit comprising:

a microcomputer configured to obtain state information of a monitoring object related to a state of the display device; and

a processor configured to update an update table storing the state information in response to periodically obtaining the state information from the microcomputer, update state display information for visually displaying the state information stored in the update table, and display the state display information in a state of being superimposed on the image information for a given period.

4. The circuit according to claim 3,

wherein there are a plurality of monitoring objects, and

wherein the processor updates the update table each time state information of one of the plurality of monitoring objects is obtained, and updates a plurality of pieces of state display information for visually displaying a plurality of pieces of state information stored in the update table and displays the plurality of pieces of state display information in a state of being superimposed on the image information for the given period in response to detecting an instruction to display the state display information in a state of being superimposed on the image information.

5. A display method displaying image information transmitted from a main body device on a display, the display method comprising:

obtaining state information of a monitoring object related to a state of a display device; and

updating, by a computer processor, an update table storing the state information in response to periodically obtaining the state information from an obtaining unit, updating state display information for visually displaying the state information stored in the update table, and displaying and controlling the state display information in a state of being superimposed on the image information for a given period.

6. The method according to claim 5,

wherein there are a plurality of monitoring objects, and

wherein the controlling updates the update table each time state information of one of the plurality of monitoring objects is obtained, and updates a plurality of pieces of state display information for visually displaying a plurality of pieces of state information stored in the update table and displays the plurality of pieces of state display information in a state of being superimposed on the image information for the given period in response to detecting an instruction to display the state display information in a state of being superimposed on the image information.
