Y/C Delay Controls
Written by The ISF Forum Library Community   
Thursday, 02 August 2007

Applies To:  All Display Types.

Y/C Delay Controls are required to minimize or correct artifacts that occur when the luminance (black & white) channel and/or one or more color channels in a video signal are not properly synchronized.

 
1:1 Pixel Mapping
Written by The ISF Forum Library Community   
Wednesday, 01 August 2007

Applies To:  All Non-CRT Displays

1:1 Pixel Matching is required to ensure that a video signal that is identical to a display's native resolution is delivered to the display on a matching, pixel-by-pixel basis, without extraneous processing or scaling that could introduce visible artifacts.

 
Auto-Defeat Controls

Wednesday, 01 August 2007

Applies To:  All Display Types

Auto Defeat Controls are required to manually disable any automated or default display features, such as black level enhancement, flesh tone correction, digital noise reduction, etc.
 
Color Isolation Controls
Written by The ISF Forum Library Community   
Wednesday, 01 August 2007

Applies To:  All Display Types

Color Isolation Controls are required to evaluate the accuracy of a display's conversion of non-RGB signals to RGB, and to correct any conversion errors via the display's color decoder controls. Where physical isolation isn't possible, an electronic means is needed in order to view each color channel separately.

 
Color Decoding Controls
Written by The ISF Forum Library Community   
Tuesday, 31 July 2007

Applies To:  All Display Types

Color Decoding Controls are required to accurately and independently adjust saturation and phase for each of the three primary color channels (red, green and blue).

 
Color Management Controls
Written by The ISF Forum Library Community   
Wednesday, 01 August 2007

Applies To:  All Non-CRT Displays

Color Management Controls are required to enable digital displays to be correctly aligned to the primary and secondary color gamut of SMPTE-C, EBU, or HDTV color standards.
 
Discrete Source Controls
Written by The ISF Forum Library Community   
Wednesday, 01 August 2007

Applies To:  All Display Types

Discrete Source Controls refer to a system architecture that allows a display to be independently adjusted for more than one signal type or video source, and to have the resulting settings for each signal or source type stored separately and then applied correctly to the active video source or signal type.

 
Edge Enhancement Controls
Written by The ISF Forum Library Community   
Wednesday, 01 August 2007

Applies To:  All Display Types

Edge Enhancement Controls are required to minimize excess sharpness or edge ringing created by the display's internal signal processing.

 
Gamma Controls
Written by The ISF Forum Library Community   
Thursday, 02 August 2007

Applies To:  All Display Types

Gamma Controls are required to achieve optimal light output at each measured step between video black and reference white.

 
Grayscale Controls (White Balance)
Written by The ISF Forum Library Community   
Thursday, 02 August 2007

Applies To:  All Display Types

Grayscale Controls are required to allow adjustment of the levels of red, green and blue light that collectively produce the shades of gray that range from video black to reference white. Grayscale is also sometimes referred to as Color Temperature or White Balance, and while these three terms are not completely interchangeable, they all relate to how a television produces the "color of white" from a mixture of the red, green and blue primary color components.

 
ISF Certified Calibration Configuration (3C)
Written by The ISF Forum Library Community   
Thursday, 02 August 2007

Applies To:  All Display Types

Certified Calibration Configuration, aka "3C," is an ISF-designed calibration system that manufacturers may incorporate into the design of their displays as a means of providing managed access to the controls needed for display calibration, including discrete controls for multiple sources and/or signal types and the ability to customize each source/signal type for day or night ambient lighting conditions.
