Abstract

A display device includes an image acquisition device, a display which displays a reference color standard and displays a color standard acquired by photographing on a screen the reference color standard through the image acquisition device, a color measurer which measures color of the acquired color standard displayed on the screen of the display, and a color calibrator which calibrates colors of an image acquired through photographing by the image acquisition device using color information measured by the color measurer.

First claim

What is claimed is:

1. A display device comprising:
an image acquisition device for photographing a reference color standard;
a display which displays a screen comprising a first region, in which the reference color standard is displayed, and a second region in which a color standard, which is acquired by photographing the reference color standard through the image acquisition device, is displayed;
a color measurer which measures color of the acquired color standard displayed on the second region of the screen of the display; and
a color calibrator which calibrates colors of an image acquired through photographing by the image acquisition device using color information measured by the color measurer.

2. The display device according to claim 1 , wherein the color of the acquired color standard is measured at different positions of the second region of the screen by the color measurer.

3. The display device according to claim 2 , wherein the color calibrator calibrates the color of the color standard acquired by the image acquisition device, and the display displays on the screen the color standard, the color of which has been calibrated.

4. The display device according to claim 3 , further comprising an image transmitter which transmits the image through a network, the colors of which have been calibrated.

5. The display device according to claim 4 , wherein the image transmitter transmits the image, the colors of which have been calibrated, using a multimedia over internet protocol (MoIP).

6. A method of calibrating color of a display device, the method comprising:
displaying a reference color standard on a screen of a display, and photographing the reference color standard through an image acquisition device;
displaying a screen comprising a first region, in which the reference color standard is displayed, and a second region in which a color standard, which is acquired by photographing the reference color standard through the image acquisition device, is displayed, and measuring color of the acquired color standard displayed on the second region of the screen through a color measurer; and
calibrating colors of an image acquired through photographing by the image acquisition device using color information measured by the color measurer.

7. The method of calibrating color according to claim 6 , further comprising calibrating the color of the color standard acquired by the image acquisition device, and displaying on the screen of the display unit the color standard, the color of which has been calibrated.

8. The method of calibrating color according to claim 7 , further comprising transmitting the image, the colors of which have been calibrated, through a network.

9. The method of calibrating color according to claim 8 , wherein, in the transmission of the image, the colors of which have been calibrated, the image, the colors of which have been calibrated, is transmitted using a multimedia over internet protocol (MoIP).

10. A display device comprising:
a display which displays a screen comprising a first region, in which a reference color standard is displayed, and a second region in which a received color standard is displayed;
a color measurer which measures color of the received color standard; and
a color calibrator which calibrates colors of an image acquired using color information measured by the color measurer.

11. The display device of claim 10 , further comprising:
an image acquisition device for photographing the reference color standard;
wherein the received color standard is acquired by photographing the reference color standard through the image acquisition device.

12. The display device of claim 11 , wherein the image calibrated by the color calibrator is acquired by the image acquisition device.

13. The display device according to claim 12 , further comprising an image transmitter which transmits the image with the calibrated colors through a network.
