Abstract

An information processing apparatus includes a video signal output unit to output different video signals to a first display unit and a second display unit, a screen switching input unit to input an instruction for switching between a screen displayed on the first display unit and a screen displayed on the second display unit, a determining unit to determine whether an input source of the input path selected for the first display unit is the video signal output unit, and an input control unit turning on the first display unit when the first display unit is turned off at the time of reception of the switching instruction, the input control unit switching the input source to the video signal output unit when the determining unit determines that the input source is not the video signal output unit.

Claims

1. An information processing apparatus using devices as a multiscreen display, comprising:

a memory; and

a processor coupled to the memory, the processor configured to

select an input path of a video signal to be displayed on a screen from a plurality of input paths

output different video signals to a first display that includes information indicating an input source of the video signal for the first display and a second display,

input an instruction for switching between a screen displayed on the first display and a screen displayed on the second display,

determine, based on the information, whether the input source of the input path selected for the first display is the video signal output for the first display, and

turn on the first display when the first display is turned off at the time of reception of the switching instruction.

2. The information processing apparatus according to claim 1, wherein the processor is further configured to switch between the video signal output to the first display and the video signal output to the second display when it is determined that the first display is turned on and the input source of the video signal is the video signal output for the first display.

3. The information processing apparatus according to claim 1, wherein the processor is further configured to output a main operation screen of the information processing apparatus to one of the first display and the second display, the processor outputting the main operation screen to the second display when the input source of the video signal of the first display is not the video signal output for the first display or the first display is turned off when the switching instruction is not input.

4. The information processing apparatus according to claim 1, wherein the first display supports a function of consumer electronics control (CEC) defined in high definition multimedia interface (HDMI).

5. The information processing apparatus according to claim 1, wherein the second display is wirelessly connected to the information processing apparatus.

6. The information processing apparatus according to claim 1, wherein the processor is further configured to:

set one of the first display and the second display as a first screen and setting the other one of the first display and the second display as a second screen, and

output the main operation screen of the information processing apparatus to the first screen and output a sub operation screen of the information processing apparatus to the second screen.

7. A control method executed by an information processing apparatus using devices as a multiscreen display, the control method comprising:

outputting different video signals to a first display that includes information indicating an input source of the video signal for the first display and a second display, one input path of a video signal to be displayed being selected for each of the first display and the second display from a plurality of input paths of the video signals;

receiving input of an instruction for switching between the video signal displayed on the first display and the video signal displayed on the second display;

turning on the first display when the first display is turned off;

acquiring information on an input source of the video signal displayed on the first display;

determining, based on the information, whether the input source of the video signal displayed on the first display is the information processing apparatus;

switching the input source to the information processing apparatus when it is determined that the input source is not the information processing apparatus; and

switching between the video signal output to the first display and the video signal output to the second display.

8. The control method according to claim 7, wherein

the video signal output to the first display and the video signal output to the second display are switched between when it is determined that the first display is turned on and the input source of the video signal is the information processing apparatus at the time of reception of input of the switching instruction.

9. The control method according to claim 7, wherein

a main operation screen of the information processing apparatus is output to one of the first display and the second display, the main operation screen being output to the second display when the input source of the video signal of the first display is not the information processing apparatus or the first display is turned off when the switching instruction is not input.

10. The control method according to claim 7, wherein

the first display supports a function of consumer electronics control (CEC) defined in high definition multimedia interface (HDMI).

11. The control method according to claim 7, further comprising:

setting one of the first display and the second display as a first screen and setting the other one of the first display and the second display as a second screen, wherein

determining, based on the information, whether the input source of the video signal displayed on the first display is the information processing apparatus;

switching the input source to the information processing apparatus when it is determined that the input source is not the information processing apparatus; and

switching between the video signal output to the first display and the video signal output to the second display.

13. The non-transitory computer-readable recording medium according to claim 12, wherein

the video signal output to the first display and the video signal output to the second display are switched between when it is determined that the first display is turned on and the input source of the video signal is the information processing apparatus at the time of reception of input of the switching instruction.

14. The non-transitory computer-readable recording medium according to claim 12, wherein
