Abstract

A misoperation processing method includes determining, in response to triggering a misoperation cancellation step, display status information of a display device. The display status information is stored in a data storage area of the display device before the misoperation occurs. The method also includes restoring a display status of the display device that existed before the misoperation occurred based on the determined display status information.

First claim

What is claimed is:

1. A misoperation processing method comprising:
determining, in response to triggering a misoperation cancellation, display status information of a display device, the display status information stored in a data storage area of the display device before the misoperation occurs; and
restoring a display status of the display device that existed before the misoperation occurred based on the determined display status information;
wherein, triggering the misoperation cancellation comprises:
evaluating whether there is an image input by a signal resource when not receiving any display image;
displaying the image input by the signal resource in response to determining that the image input is present;
evaluating, in response to determining that the image input is not present, whether to wait for the signal resource to input an image;
entering a standby state of NO SIGNAL in response to determining to wait for the signal resource; and
triggering the misoperation cancellation in response to determining not to wait for the signal resource.

2. The method according to claim 1 , wherein the display status information of the display device includes structure variable information of a display image on the display device.

3. The method according to claim 2 , wherein the structure variable information includes a path, a channel and a volume of the display image.

4. The method according to claim 3 , further comprising storing the structure variable information of the display image as pre-stored information in an inerasable data storage area in a stack of the data storage area of the display device before the misoperation occurs.

5. The method according to claim 4 , wherein, determining the display status information of the display device before the misoperation occurs comprises:
determining the structure variable information of the display image based on an address pointer of the structure variable information of the display image stored in the inerasable data storage area before the misoperation occurs.

6. The method according to claim 1 , wherein, evaluating whether to wait for the signal resource to input the image, further comprises:
outputting a prompt interface for a user to choose whether to wait for the signal resource to input an image, and waiting for receiving a user instruction through the prompt interface, wherein a waiting time for receiving the user instruction through the prompt interface is less than a waiting time for the standby state of NO SIGNAL; and
entering the standby state of NO SIGNAL if the user instruction for entering the standby state of NO SIGNAL is received in the period of waiting for receiving user instruction through the prompt interface, otherwise, triggering the misoperation cancellation.

7. The method according to claim 1 , further comprising:
receiving an interrupt message to switch signal resources;
evaluating whether there is a signal resource inputting an image;
determining format information of the image and displaying the image input by the signal resource in response to determining that the signal resource is inputting an image; and
determining that no display image is being received in response to determining that the signal resource is not inputting an image.

8. The method according to claim 1 , wherein triggering the misoperation comprises: receiving a display image and a user instruction of triggering the misoperation cancellation, and triggering the misoperation cancellation.

9. A misoperation processing apparatus comprising:
a storage unit for pre-storing display status information of a display device in a data storage area before a misoperation occurs;
a judgment unit for evaluating whether to trigger a misoperation cancellation;
a determination unit for determining, in response to triggering the misoperation cancellation, the display status information of the display device pre-stored in the data storage area of the display device; and
a display unit for restoring the display status of the display device based on the display status information pre-stored in the data storage area,
wherein the display status information of the display device comprises structure variable information of a display image on the display device,
wherein the judgment unit is configured to evaluate whether there is a signal resource inputting an image when not receiving any display image, to display the image input by the signal resource in response to determining that the signal resource is inputting the image, to evaluate whether to wait for the signal resource to input the image in response to determining that the signal resource is not inputting the image, to enter a standby state of NO SIGNAL in response to determining to wait for the signal resource, and to trigger the misoperation cancellation in response to determining not to wait for the signal resource.

10. The apparatus according to claim 9 , wherein the structure variable information comprises a path, a channel and a volume of the display image.

11. The apparatus according to claim 10 , wherein the structure variable information of the display image pre-stored in the data storage area is stored in an inerasable data storage area in a stack.

12. The apparatus according to claim 11 , wherein, the determination unit is configured to determine the structure variable information of the display image based on an address pointer of the structure variable of the display image pre-stored in the inerasable data storage area before the misoperation occurs.

13. The apparatus according to claim 9 , wherein the judgment unit is further configured to output a prompt interface for a user to choose whether to wait for the signal resource to input the image, and to wait for receiving a user instruction through the prompt interface, wherein a waiting time for receiving the user instruction through the prompt interface is less than a waiting time for the standby state of NO SIGNAL;
wherein the judgment unit is configured to, in response to receiving the user instruction of entering the standby state of NO SIGNAL in the period of waiting for receiving the user instruction through the prompt interface, enter the standby state of NO SIGNAL; and
wherein the judgment unit is configured to trigger the misoperation cancellation after the period of waiting for receiving the user instruction expires without the judgment unit having received the user instruction.

14. The apparatus according to claim 9 , wherein the judgment unit is configured to:
receive an interrupt message to switch signal resources; and
evaluate whether there is a signal resource inputting an image, determine format information of the image and display the image input by the signal resource in response to determining that the signal resource is inputting the image, and to determine that the display image is not received in response to determining that the signal resource is not inputting the image.

15. The apparatus according to claim 9 , wherein, the judgment unit is configured to, in response to receiving a display image and a user instruction of triggering misoperation cancellation trigger the misoperation cancellation.

16. A display device comprising the apparatus according to claim 9 .

17. A display device comprising the apparatus according to claim 15 .
