Test Pattern Notes
Color 75 Group
-
75% Tri-split Color Bars
- Adjust Color Saturation and Hue controls by
matching color bars while individually viewing each primary color. (Use display
controls to enable single primary colors, or view through color filters.) Similar to
SMPTE Color Bars, but offset and split for easier use.
-
75% Color Bars
- Standard Color Bars
-
75% Color Windows
(7) – Primary, complementary, and gray windows provide
accurate CIE color measurements by using the same screen area.
Color 100 Group
-
100% Tri-split Color Bars
- Check Color Saturation & Hue at 100% levels.
-
100% Color Bars
- Standard Color Bars at 100% levels.
-
100% Color Fields
(7)
- Measure color field uniformity and chroma noise.
User Colors
- Replaces 75% and 100% gray colors in both Color 75 and Color 100
group patterns to provide easy comparison with other standard colors.
Special Group
-
Cross-Hatch
- Low APL pattern to measure geometry & convergence.
-
Inverse Cross-Hatch
- High APL pattern for geometry & convergence.
-
Dual Needle Pulse
– Adjust CRT Contrast. Measure short-term CRT high-
voltage stability and check for CRT Scan Velocity Modulation.
-
Color Pixel Multiburst
- Adjust chroma-luma delay and signal peaking
(Sharpness/Detail Controls). Red/cyan, black/white, and blue/yellow bursts.
1080i/p & 720p - 5,4,3,2,1 pixel bursts - 7.4, 9.3, 12.4, 18.5, 37.1 MHz
480p & 576p – 5,4,3,2,1 pixel bursts - 2.7, 3.4, 4.5, 6.75, 13.5 MHz
480i & 576i –
-
Luma Pixel Multiburst
- Adjust signal peaking (Sharpness/Detail Controls).
1080i/720p - 5,4,3,2,1 pixel bursts - 7.4, 9.3, 12.4, 18.5, 37.1 MHz
480p & 576p – 5,4,3,2,1 pixel bursts - 2.7, 3.4, 4.5, 6.75, 13.5 MHz
480i & 576i –
-
Polyphase Chroma Sweep –
Measure Y/C and CVBS Pb & Pr chroma
bandwidth with 1.0, 1.5, 2.0, 2.5, and 3.0 MHz frequency markers.
-
CrossHair
– Check centering and edge artifacts on lines.
-
Sharpness
- 1,2,3,4,5 pixel-width black vertical lines, 1,2,3,4,5 pixel-height
(480p/576p/720p/1080p) or 2,4,6,8,10 (480i/576i/1080i) pixel-height black
horizontal lines. Adjust Sharpness, Detail Enhancement. 50% background.
-
4x4 100% Checkerboard/Inverse & 4x4 User Level Checkboard/Inverse
(4) -
Measure ANSI & m-ANSI contrast ratio at multiple luma levels.
