Abstract
A definition control method and an image display device using the same are provided. The definition control method includes displaying a first pattern and a second pattern, inputting a control value, and changing a display state of the first pattern according to the input control value, wherein a display state of the second pattern is not changed by the control value.
Claims59
A definition control method of an image display device, the method comprising:
- displaying a first pattern and a second pattern;
- inputting a control value;
- and
- changing a display state of the first pattern according to the input control value,
- wherein the first pattern includes a plurality of regions having different levels of brightness,
- wherein, in brightness control, the first pattern includes a first region having a level of brightness greater than 0 IRE, a second region having a level of brightness equal to 0 IRE and a third region having a level of brightness less than 0 IRE, and
- wherein a display state of the second pattern is not changed by the control value.

An image display device comprising:
- a memory storing a first pattern and a second pattern;
- a user input unit through which a user inputs a control value;
- a signal processing unit performing imaging processing upon the first pattern according to the input control value;
- and
- a display unit displaying a first pattern input from the signal processing unit, and a second pattern stored in the memory,
- wherein the first pattern includes a plurality of regions having different levels of brightness, and
- wherein, in brightness control, the first pattern includes a first region having a level of brightness greater than 0 IRE, a second region having a level of brightness equal to 0 IRE and a third region having a level of brightness less than 0 IRE.
4 more elements
An image display device having a control menu, comprising:
- an image displayed in a first region;
- a first pattern displayed in a second region,
- wherein the first pattern includes a plurality of areas having different levels of brightness, and
- wherein, in brightness control, the first pattern includes a first area having a level of brightness greater than 0 IRE, a second area having a level of brightness equal to 0 IRE and a third area having a level of brightness less than 0 IRE;
- a second pattern displayed in a third region;
- and
- a control value display On Screen Display (OSD) displayed in a fourth region,
- wherein the control value display OSD includes a fixed region and a variable region, the variable region is variably displayed according the input control value and displays a value of a definition element by using a number, a character or an abstract degree, and the image in the first region and the first pattern in the second region are changed according to a change in the control value,
- wherein the input control value is set when the levels of brightness of the second and third regions visually match each other.
