Abstract

Sony has introduced "sRGB color," which is standardized by IEC (International Electro technical Commission). The sRGB is a standard to prescribe the standardized color between display monitor, printer, digital camera and so on. The specification of the sRGB color for a monitor is prescribed by the IEC:

sRGB COLOR SWITCHING CONTROL

Sony has introduced "sRGB color," which is standardized by IEC (International Electro technical Commission). The sRGB is a standard to prescribe the standardized color between display monitor, printer, digital camera and so on. The specification of the sRGB color for a monitor is prescribed by the IEC:

Sony monitors that possess the sRGB color feature realize results that exceed specification in color temperature control, contrast control, and brightness control-the color temperature is adjusted to 6500K, the contrast is adjusted to some value to satisfy 80 nit of brightness, and brightness is adjusted to some value to satisfy 2.2 of gamma. The monitors with sRGB also allow the user to adjust contrast and brightness to select their own colors.

The problem is that the user can be confused between the original sRGB color setting and their own setting, with the user being unable to maintain his/her designated user setting if the user later changes the setting back to the original sRGB setting.

When the user selects the sRGB color by using the front key, the micro-controller loads the color registers (R/G/B cutoff and R/G/B drive) for sRGB color from EEPROM via the 12C Bus. The micro-controller also loads the contrast and brightness settings according to the sRGB color switch condition. For example, if the switch is on, the micro-controller loads the data from the EEPROM factory default area, selecting the original setting of contrast and brightness. Otherwise,...
