Digital device, and system and method for controlling color using same

A color control system, comprising:

• a remote control device calculating and sensing a gain value of a prescribed color through a color gain adjusting window having a multitude colors arrayed thereon, the remote control device comprising a mobile terminal, a remote controller, a smartphone, or a smartwatch;
• and
• a digital device comprising a display unit and adjusting calibration of a display panel according to a color gain value received from the remote control device,
• wherein the remote control device displays the color gain adjusting window on a display of the remote control device in response to a first input,
• wherein the remote control device extracts each of unique R, G and B values of a color selected from the color gain adjusting window,
• wherein the remote control device adds or subtracts the extracted unique R, G and B values to or from R, G and B buffers, respectively, in response to a second input received via the color gain adjusting window,
• wherein the remote control device increases a gain value of the color when at least one of accumulated values of the R, G and B buffers is equal to or greater than ‘1’,
• wherein the remote control device decreases a gain value of the corresponding color when at least one of accumulated values of the R, G and B buffers is equal to or less than ‘0’, and
• wherein the remote control device sends the increased or decreased gain value of the color to the digital device.

A color control method, comprising:

• checking whether a first input is received;
• when the first input is received via an input unit comprising at least one of a touch screen, a keypad, a dome switch, a touchpad, a jog wheel, or a jog switch, displaying, on a display unit, a color gain adjusting window having a multitude of colors arrayed thereon;
• checking whether a prescribed color is selected from the color gain adjusting window;
• extracting each of unique R, G and B values of the selected color in response to selection of a color from the color gain adjusting window;
• checking whether a second input is received from the color gain adjusting window;
• adding or subtracting the extracted unique R, G and B values to or from R, G and B buffers, respectively, in response to the second input;
• checking whether at least one of accumulated values of the R, G and B buffers is equal to or greater than ‘1’ or equal to or less than ‘0’;
• when the at least one of accumulated values of the R, G and B buffers is equal to or greater than ‘1’, increasing a gain value of the color;
• and
• when the at least one of the accumulated values of the R, G and B buffers is equal to or less than ‘0’, decreasing the gain value of the color.
