Abstract

An information processing apparatus includes circuitry. The circuitry controls a display to display a symbol corresponding to operation by a user during a first period of time since occurrence of the operation. The circuitry controls output of an image indicating a content displayed on the display to an external apparatus, so as not to output the image to the external apparatus during a second period of time that is equal to or longer than the first period of time.

First claim

What is claimed is:

1. An information processing apparatus comprising circuitry to:
control a display to display a symbol corresponding to an operation by a user during a first period of time subsequent to an occurrence of the operation;
control the display to mask display of the symbol upon the first period of time being elapsed; and
control output of an image indicating a content displayed on the display to an external apparatus, so as to prevent output of the image to the external apparatus during a second period of time, the second period of time being equal to or longer than the first period of time.

2. The information processing apparatus of claim 1 , further comprising a receiver to receive a request for acquisition of the image, the request being transmitted from the external apparatus in response to a user instruction to the external apparatus,
wherein the circuitry is configured to control the output so as to prevent transmission of the image to the external apparatus in response to the request received by the receiver during the second period of time.

3. The information processing apparatus of claim 1 , wherein:
the circuitry is further configured to detect the occurrence of the operation and an end of the operation;
wherein the first period of time starts when the occurrence of the operation is detected; and
the second period of time starts when the end of the operation is detected.

4. The information processing apparatus of claim 2 , wherein:
the circuitry is further configured to detect the occurrence of the operation and an end of the operation;
wherein the first period of time starts when the occurrence of the operation is detected; and
the second period of time starts when the end of the operation is detected.

5. The information processing apparatus of claim 1 , wherein the circuitry is configured to control the output so as to prevent output of the image to the external apparatus during a period of time from the occurrence of the operation to an end of the operation.

6. The information processing apparatus of claim 2 , wherein the circuitry is configured to control the output so as to prevent output of the image to the external apparatus during a period of time from the occurrence of the operation to an end of the operation.

7. The information processing apparatus of claim 1 , wherein the circuitry is further configured to:
accept setting of the first period of time; and
determine the second period of time based on the setting accepted, of the first period of time, and
wherein the circuitry is configured to control the output so as to prevent output of the image to the external apparatus during the second period of time determined based on the setting accepted, of the first period of time.

8. The information processing apparatus of claim 1 , wherein the circuitry being configured to control the display to mask the symbol, further includes the circuitry being configured to control the display to replace display of the symbol with display of another symbol upon the first period of time being elapsed.

9. An information processing method performed by an information processing apparatus, the method comprising:
controlling a display to display a symbol corresponding to an operation by a user during a first period of time subsequent to occurrence of the operation;
controlling the display to mask display of the symbol upon the first period of time being elapsed; and
controlling an output of an image indicating a content displayed on the display to an external apparatus, so as to prevent output of the image to the external apparatus during a second period of time, the second period of time being equal to or longer than the first period of time.

10. The information processing method of claim 9 , further comprising:
receiving a request for acquisition of the image, the request being transmitted from the external apparatus in response to a user instruction to the external apparatus,
wherein the controlling of the output includes controlling the output so as to prevent transmission of the image to the external apparatus in response to the received request during the second period of time.

11. The information processing method of claim 9 , further comprising detecting the occurrence of the operation and an end of the operation,
wherein the first period of time starts when the occurrence of the operation is detected, and
the second period of time starts when the end of the operation is detected.

12. The information processing method of claim 10 , further comprising detecting the occurrence of the operation and an end of the operation,
wherein the first period of time starts when the occurrence of the operation is detected, and
the second period of time starts when the end of the operation is detected.

13. The information processing method of claim 9 , wherein the controlling of the output includes controlling the output so as to prevent output of the image to the external apparatus during a period of time from the occurrence of the operation to an end of the operation.

14. The information processing method of claim 10 , wherein the controlling of the output includes controlling the output so as to prevent output of the image to the external apparatus during a period of time from the occurrence of the operation to an end of the operation.

15. The information processing method of claim 9 , further comprising:
accepting setting of the first period of time; and
determining the second period of time based on the setting accepted, of the first period of time,
wherein the controlling of the output includes controlling the output so as to prevent output of the image to the external apparatus during the second period of time determined.

16. The information processing method of claim 9 , wherein the controlling of the display to mask of the symbol includes replacing display of the symbol with display of another symbol upon the first period of time being elapsed.

17. A non-transitory computer-executable storage medium storing a computer-executable product that causes a computer to perform an information processing method, the method comprising:
controlling a display to display a symbol corresponding to an operation by a user during a first period of time subsequent to occurrence of the operation;
controlling the display to mask display of the symbol upon the first period of time being elapsed; and
controlling an output of an image indicating a content displayed on the display to an external apparatus, so as to prevent output of the image to the external apparatus during a second period of time, the second period of time being equal to or longer than the first period of time.

18. The non-transitory computer-executable storage medium of claim 17 , wherein the method further comprises:
receiving a request for acquisition of the image, the request being transmitted from the external apparatus in response to a user instruction to the external apparatus,
wherein the controlling of the output includes controlling the output so as to transmit prevent transmission of the image to the external apparatus in response to the received request during the second period of time.

19. The non-transitory computer-executable storage medium of claim 17 , wherein the method further comprises detecting the occurrence of the operation and an end of the operation,
wherein the first period of time starts when the occurrence of the operation is detected, and
the second period of time starts when the end of the operation is dete
