Output selection device and output selection method for video signals
View Patent ↗Video signals that are reproduced or processed are outputted to a first video image display device. An illuminance detection section detects the ambient illuminance during the output of the video signals. In the case that the detected illuminance is equal to or greater than a predetermined threshold, the reproduced or processed video signals are outputted to a second video image display device which provides a display with lower brightness than that for a display provided by the first video image display device.
1. A video signal output device comprising:
a first output section which outputs video signals to a first display device;
an illuminance detection section which detects ambient illuminance;
a determining section which determines whether or not the ambient illuminance detected by said illuminance detection section is equal to or greater than a predetermined value; and
a second output section which, in a case that said determining section determines that the ambient illuminance is equal to or greater than the predetermined value, outputs the video signals to a second display device, said second display device providing a display with higher brightness than that for a display provided by said first display device.
2. The device according to claim 1 , further comprising a reproducing section which reproduces video signals, wherein the video signals reproduced by said reproducing section are inputted to said first output section or/and said second output section.
3. The device according to claim 1 , further comprising a signal processing section which executes given processing on the video signals, wherein the video signals processed by said signal processing section are inputted to said first output section or/and said second output section.
4. The device according to claim 3 , further comprising a value input section which allows a user to input the predetermined value.
5. The device according to claim 3 , wherein, in a case that said determining section determines that the ambient illuminance is equal to or greater than the predetermined value, said first output section refrains from outputting the video signals to said first display device.
6. The device according to claim 3 , wherein, in a case that said determining section determines that the ambient illuminance is equal to or greater than the predetermined value, said first output section outputs the video signals to said first display.
7. The device according to claim 3 , wherein said second display device is provided externally.
8. The device according to claim 3 , wherein said second display device is provided internally.
9. The device according to claim 3 , further comprising a signal superimposing section which superimposes a given video signal on the processed video signals.
10. The device according to claim 9 , further comprising an instruction input section which allows a user to input an instruction to make said signal imposing section superimpose a given video signal on the video signals.
11. A method for outputting video signals, comprising:
outputting video signals to a first display device;
detecting ambient illuminance during the output of the video signals;
determining whether or not detected illuminance is equal to or greater than a predetermined value; and
outputting, in a case that it is determined that the ambient illuminance is equal to or greater than the predetermined value, the video signals to a second display device, said second display device providing a display with higher brightness than that for a display provided by said first display device.
12. The method according to claim 11 , further comprising reproducing video signals, wherein the video signals reproduced by said reproducing are inputted to said first display device or/and said second display device.
13. The method according to claim 11 , further comprising executing given processing on the video signals, wherein the video signals processed by said executing are inputted to said first display device or/and said second display device.
14. The method according to claim 13 , wherein the predetermined value is inputted by a user.
15. The method according to claim 13 , wherein the inputted video signals are, in a case that it is determined that the ambient illuminance is equal to or greater than the predetermined value, refrained from being outputted to said second display device.
16. The method according to claim 13 , wherein the inputted video signals are, in a case that it is determined that the ambient illuminance is equal to or greater than the predetermined value, outputted to said second display device.
17. The method according to claim 13 , wherein a given video signal is further superimposed on the processed video signals.
18. The method according to claim 17 , wherein an instruction to superimpose a specified video signal on the processed video signals is inputted by a user.
