Abstract

Provided is a multi-monitor system that includes display devices having different luminance levels with respect to the same set luminance value and that can easily match the luminance levels of the display devices. A multi-monitor system including a plurality of display devices includes a processor that, on the basis of respective luminance information values of a particular display device and the other display device of the plurality of display devices and a set luminance value of the particular display device arbitrarily set by a user, calculates set luminance value of the other display device in such a manner that luminance level of the other display device becomes substantially equal to a luminance level of the particular display device.

First claim

1 - 33 . (canceled)

34 . A multi-monitor system comprising a plurality of display devices, the multi-monitor system comprising:
a processor that, on the basis of a relationship between luminance information values of one display device and the other display device of the plurality of display devices, the one display device serving as a master display device, the other display device serving as slave display device, and a set luminance value of the master display device arbitrarily set by a user, calculates set luminance value of the slave display device.

35 . The multi-monitor system of claim 34 , wherein the processor calculates the set luminance values of the slave display devices in such a manner that luminance level of the slave display device is substantially equal to a luminance level of the master display device.

36 . The multi-monitor system of claim 34 , wherein the luminance information value is an actually measured luminance value corresponding to a particular set luminance value, a representative luminance value corresponding to a particular set luminance value of a display device of an identical type, or a set luminance value corresponding to a particular actually measured luminance value, or a value calculated on the basis of one of these values.

37 . The multi-monitor system of claim 34 , wherein the processor calculates the set luminance value of the slave display device on the basis of Formula 1-3:
set luminance value of slave display device=set luminance value of master display device×(luminance information value of master display device/luminance information value of slave display device).

38 . The multi-monitor system of claim 34 , wherein the luminance information value is calculated on the basis of at least RGB luminance information values and RGB gain values, the RGB luminance information values being composed of luminance information values of R, G, and B.

39 . The multi-monitor system of claim 34 , wherein the luminance information value is determined according to a particular color temperature arbitrarily set by a user.

40 . The multi-monitor system of claim 34 , wherein the particular set luminance value is a maximum value.

41 . The multi-monitor system of claim 34 , wherein the processor is disposed in one of the display devices in the multi-monitor system or disposed in a controller, the controller being disposed independently of the display devices.

42 . A computer program used by a multi-monitor system comprising a plurality of display devices, the computer program causing a computer to perform:
a calculation step of, on the basis of a relationship between luminance information values of one display device and the other display device of the plurality of display devices, the one display device serving as a master display device, the other display device serving as slave display device and a set luminance value of the master display device arbitrarily set by a user, calculating set luminance value of the slave display device.

43 . The computer program of claim 42 , wherein the calculation step comprises calculating the set luminance value of the slave display device in such a manner that luminance level of the slave display device is substantially equal to a luminance level of the master display device.

44 . The computer program of claim 42 , wherein the luminance information value is an actually measured luminance value corresponding to a particular set luminance value, a representative luminance value corresponding to a particular set luminance value of a display device of an identical type, or a set luminance value corresponding to a particular actually measured luminance value, or a value calculated on the basis of one of these values.

45 . The computer program of claim 42 , wherein the calculation step comprises calculating the set luminance value of the slave display device on the basis of Formula 1-3:
set luminance value of slave display device=set luminance value of master display device×(luminance information value of master display device/luminance information value of slave display device).

46 . The computer program of claim 42 , wherein the luminance information value is calculated on the basis of at least RGB luminance information values and RGB gain values, the RGB luminance information values being composed of luminance information values of R, G, and B.

47 . The computer program of claim 42 , wherein the luminance information value is determined according to a particular color temperature arbitrarily set by a user.

48 . The computer program of claim 42 , wherein the particular set luminance value is a maximum value.

49 . A display device used by a multi-monitor system comprising a plurality of display devices, the display device comprising:
a processor that, on the basis of a relationship between luminance information values of one display device and the other display device of the plurality of display devices, the one display device serving as a master display device, the other display device serving as slave display device, and a set luminance value of the master display device arbitrarily set by a user, calculates set luminance value of the slave display device; and a transmitting unit that transmits the set luminance values calculated by the processor to the slave display device.

50 . The display device of claim 49 , wherein the processor calculates the set luminance value of the slave display device in such a manner that luminance level of the slave display device is substantially equal to a luminance level of the master display device.

51 . The display device of claim 49 , wherein the luminance information value is an actually measured luminance value corresponding to a particular set luminance value, a representative luminance value corresponding to a particular set luminance value of a display device of an identical type, or a set luminance value corresponding to a particular actually measured luminance value, or a value calculated on the basis of one of these values.

52 . The display device of claim 49 , wherein the processor calculates the set luminance value of the slave display device on the basis of Formula 1-3:
set luminance value of slave display device=set luminance value of master display device×(luminance information value of master display device/luminance information value of slave display device).
