Abstract

Claims (64)

1. An information processing device comprising:

processing circuitry configured to:

accept an input of an emulation setting relating to a function of a display monitor as a target of emulation, the emulation setting comprising a variable range including a lower-limit value and an upper-limit value of a variable refresh rate during implementation of the emulation on the display monitor;

manage execution of an application program; and

execute a display output of an image rendered by executing the application program on the display monitor, in such a manner as to emulate a state in which the emulation is implemented as a virtual display monitor with a function represented by the accepted emulation setting on the display monitor.

2. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

accept the emulation setting by acquiring information representing a function of the display monitor connected to the information processing device;

present options of emulation that are allowed to be virtually set, on a basis of the acquired information; and

cause the presented options to be selected.

3. The information processing device according to claim 1 , wherein the emulation setting includes

whether or not to limit variation of the variable refresh rate of each frame.

4. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

obtain a target value of a refresh rate demanded by the application program,

determine whether the target value is between the lower-limit value and the upper-limit value of the variable refresh rate indicated by the emulation setting, and

execute processing defined in a system program when the target value is not between the lower-limit value and the upper-limit value.

5. The information processing device according to claim 4 , wherein the processing circuitry is further configured to

set the target value to the upper-limit value when the target value exceeds the upper-limit value,

set the target value to the lower-limit value when the target value is below the lower-limit value, and

notify the application program of the emulation setting change.

6. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

obtain an absolute value of a difference between a current refresh rate and a target refresh rate,

determine whether the absolute value exceeds a predetermined limit defined in the emulation setting, and

adjust the target refresh rate when the absolute value exceeds the predetermined limit.

7. The information processing device according to claim 6 , wherein the processing circuitry is further configured to

set the target refresh rate to a sum of the current refresh rate and the predetermined limit when the target refresh rate is greater than the current refresh rate.

8. The information processing device according to claim 6 , wherein the processing circuitry is further configured to

set the target refresh rate to a difference between the current refresh rate and the predetermined limit when the target refresh rate is less than the current refresh rate.

9. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

output a settled target refresh rate to the display monitor,

complete rendering of a frame by processing of the application program,

output a signal of video of the rendered frame to the display monitor, and

repeat a target value setting processing when a target value specified by the application program and the settled target refresh rate are different.

10. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

acquire a lower-limit value and an upper-limit value of a variable refresh rate range from the display monitor,

present options for selecting the lower-limit value and the upper-limit value of the variable refresh rate for the emulation within the acquired range, and

accept user input for selecting the lower-limit value and the upper-limit value for the emulation setting.

11. The information processing device according to claim 1 , wherein the processing circuitry is further configured to

acquire information indicating whether the display monitor physically connected is a limited display monitor involving a limit on a rate of variation in the variable refresh rate between frames,

present an option for selecting whether to emulate a limited display monitor when the acquired information indicates that the display monitor physically connected is not a limited display monitor, and

accept user input for selecting whether to emulate a limited display monitor.

12. A control method of an information processing device in which the information processing device including a processor is used, the method comprising:

by the processor,

accepting an input of an emulation setting relating to a function of a display monitor as a target of emulation, the emulation setting comprising a variable range including a lower-limit value and an upper-limit value of a variable refresh rate during implementation of the emulation on the display monitor;

managing execution of an application program; and

executing a display output of an image rendered by executing the application program on the display monitor, in such a manner as to emulate a state in which the emulation is implemented as a virtual a display monitor with a function represented by the accepted emulation setting on the display monitor.

13. The control method of claim 12 , further comprising:

obtaining a target value of a refresh rate demanded by the application program;

determining whether the target value is between a lower-limit value and an upper-limit value of a variable refresh rate indicated by the emulation setting; and

executing processing defined in a system program when the target value is not between the lower-limit value and the upper-limit value.

14. The control method of claim 13 , further comprising:

setting the target value to the upper-limit value when the target value exceeds the upper-limit value;

setting the target value to the lower-limit value when the target value is below the lower-limit value; and

notifying the application program of the emulation setting change.

15. The control method of claim 12 , further comprising:

obtaining an absolute value of a difference between a current refresh rate and a target refresh rate;

determining whether the absolute value exceeds a predetermined limit defined in the emulation setting; and

adjusting the target refresh rate when the absolute value exceeds the predetermined limit.

16. The control method of claim 15 , further comprising:

setting the target refresh rate to a sum of the current refresh rate and the predetermined limit when the target refresh rate is greater than the current refresh rate.

17. The control method of claim 15 , further comprising:

set the target refresh rate to a difference between the current refresh rate and the predetermined limit when the target refresh rate is less than the current refresh rate.

18. A non-transitory computer-readable recording medium that stores a program for a computer thereon which, when executed by the computer causes the computer to perform a method comprising:
