A good understanding of the meaning of color temperature will enable better adjustments of LCD monitor picture quality.Note: Below is the translation from the Japanese of the ITmedia article "Altering a color dramatically with a single setting: Examining color temperature on an LCD monitor" published March 30, 2009. While color temperature dramatically affects the picture quality of an LCD monitor, more often than not, people simply use the default settings. Making Full Use of the "External" LCD with Laptop ComputersIn this article, we'll focus on color temperature, a fundamental parameter in picture quality adjustments. The difference in image quality is perfectly obvious! – Let's check the LCD's display
Color temperature is specified in units of Kelvin (K) of absolute temperature, not the degrees Celsius (C) used to express the temperature of air and other materials. Color temperature refers to the color of light, serving as the standard index for color balance for a range of products, including monitors, cameras, and lighting equipment. Since color temperature settings affect color reproduction significantly on an LCD monitor, if a user wants to display an image with the appropriate color cast, he or she must choose the correct color temperature.We'll start with a brief explanation of the meaning of color temperature.
Since daylight has a color temperature of 5000-5500 K, setting the white balance to this figure makes it possible to capture photos with color reproduction close to that perceived by the eye.A diagram of color temperature. Most photographers shooting pictures with digital SLR cameras might set their white balance to 5000-5500 K. As you can probably guess, lower color temperatures mean redder light, while higher temperatures mean bluer light.
First, assume a subject that can completely absorb heat and light, then radiate this energy back out. Here we'll touch briefly on the technical definition of color temperature. Note that this diagram is merely a rough representation of how to think about color temperatures, not a precise indication of color temperatures under specific conditions.Color is expressed as a temperature due to the relationship between the color of light and temperatures when objects are heated to high temperatures. As color temperature increases, white gradually turns to blue.
While this is a complex topic with detailed explanations grounded in physics and mathematics, we do not need to understand this in depth to adjust the color temperature of an LCD monitor. For this reason, a black body is an idealized object, used to generate standard values by matching specific colors of radiated light to specific temperatures. This is how color temperature is defined.While any object will radiate various light frequencies when heated to high temperature, the temperature at which the light becomes a certain color differs from object to object. Third, assume that the temperature of the black body when it radiates a certain color of light is also understood to describe that color. Second, assume that this black body radiates light when heated and that the wavelength and spectrum of this light varies with the temperature of the black body.
Camera White Balance Plus 9300 K
Most offer significantly fewer options in the OSD menu: 5000, 6500, and 9300 K, for example.On most EIZO LCD monitors, users can adjust color temperature precisely from the OSD menu in 500-K intervals (photo at left). Some other LCD monitors allow users to designate color temperature by Kelvin value. This is industry-leading precision. For example, on most EIZO LCD monitors, users can choose from about 14 levels (in 500-K intervals from 4000 to 10,000 K, plus 9300 K).
In most cases, even products whose color-temperature settings use terms like "blue" and "red" will be adjusted to close to 6500 K for standard mode, although accuracy may be lacking. If a monitor offers an sRGB mode, setting it to this mode should present no problems. Most LCD monitors offer a setting of 6500 K among their color temperature options. Some major real-world examples are given below.A color temperature of 6500 K is standard for ordinary PC use and for the sRGB standard.
Some products offer a picture mode with a color temperature around 9300 K as a "movie" or similar mode. However, most people appear to be accustomed to television and often perceive PC screens as having a reddish cast. Television pictures actually have a pronounced blue cast. This is significantly above the 6500 K standard for PC environments.
When watching video on a PC, users should set the LCD monitor's color temperature between 6500 K and 9300 K, checking for differences in color reproduction.As a rule of thumb, most Japanese film titles assume a 9300 K environment, while non-Japanese films assume a 6500 K environment. The international standard for digital high-definition television (ITU-R BT.709) also specifies a color temperature of 6500 K. Broadcasting standard (NTSC) calls for a color temperature standard of 6500 K.
