Abstract

An image display device including an image input means to which image signals are input, an image display means for forming an optical image based on the image signals, and a device adjusting means for adjusting internal conditions of the device is provided with an adjusting operation support means for supporting an operation of the device adjusting means. Because the adjusting operation support means is provided, a user may easily adjust the image display device while confirming adjusting operation support information displayed by the adjusting operation support means.

Claims

1. A method of displaying support information which enables an operator to adjust settings of an image display device or to solve a problem occurring in the image display device, the method comprising:

detecting, with a central processing unit, internal conditions of the image display device;

providing inquiring messages based on the detected internal conditions identifying problems occurring in the image display device and assisting messages each showing information for assisting an operator to solve a respective one of the identified problems;

providing associations between the inquiring messages and the assisting messages, each of the associations being defined by at least one of the detected internal conditions;

displaying the inquiring messages on a help screen such that an operator can select one of the inquiring messages; and

displaying at least one assisting message on the help screen in accordance with the associations, if the operator selects one of the inquiring messages.

2. A method of displaying support information according to claim 1, wherein one or more assisting messages are not displayed on the help screen, if the one or more assisting messages are determined to be unnecessary for the operator by a detected internal condition.

3. A method of displaying support information according to claim 1, further comprising:

providing operation switches operable by the operator to adjust the at least one of the detected internal conditions of the image display device; and

displaying a value identifying the at least one of the detected internal conditions with the assisting message on the help screen.

4. A method of displaying support information according to claim 1, further comprising:

providing a signal input terminal on the image display device, the signal input terminal configured to receive a plurality of types of signal; and

detecting a signal mode identifying what type of signal is received,

each of the associations being defined by the signal mode.

5. A method of displaying support information according to claim 1, wherein the assisting messages contain information regarding events that will occur for an object to be adjusted.

6. An image display device capable of displaying support information which enables an operator to adjust settings of an image display device or to solve a problem occurring in the image display device, the image display device comprising:

a detecting unit that detects, with a central processing unit, internal conditions of the image display device;

a storage device that stores inquiring messages based on the detected internal conditions identifying problems occurring in the image display device and assisting messages each showing information for assisting an operator to solve a respective one of the identified problems;

a table that associates the inquiring messages with the assisting messages, each of the associations in the table being defined by one of the detected internal conditions; and

an adjusting operation support device that displays the inquiring messages on a help screen such that an operator can select one of the inquiring messages, and displays at least one assisting message in accordance with the associations, if the operator selects one of the inquiring messages.

7. An image display device according to claim 6, wherein one or more assisting messages are not displayed on the help screen, if the one or more assisting messages are determined to be unnecessary for the operator by a detected internal condition.

8. An image display device according to claim 6, further comprising:

operation switches operable by the operator to adjust the one of the detected internal conditions of the image display device, wherein the adjusting operation support device displays a value identifying the one of the detected internal conditions with the assisting message on the help screen.

9. An image display device according to claim 6, further comprising:

a signal input unit that is configured to receive a plurality of types of signal,

wherein the detecting unit detects a signal mode identifying what type of signal is received by the signal input unit, and each of the associations is defined by the signal mode.

10. An image display device according to claim 6, wherein the assisting messages contain information regarding events that will occur for an object to be adjusted.
