Test Pattern FPD shows Description
1-Pixel
Horizontal
Lines
HLIN This test pattern consists of an alternating series of 1-pixel black and white horizontal lines. The test pattern alternates
black and white pixels in only the vertical direction. This pattern is useful for exactly matching the iScan’s output resolu-
tion to that of the display to achieve 1:1 pixel mapping and bypass any scaling operation which may be incorporated in
the display. Its use is similar to that of the 1-pixel checkerboard, but it operates only in the vertical direction.
This pattern is blacked-out for the 1080i output resolution due to the severe flicker it causes on some displays.
Frame Rate JUDD The Frame Rate Conversion test pattern consists of a vertical bar which moves slowly back and forth across the screen. The
bar’s motion is updated once in each output frame period of the iScan, and it moves a fixed number of pixels
horizontally in each frame period. This moving bar test pattern is intended to identify the frame rates at which a display
will operate. If the display is not performing any frame rate conversion, i.e., it is actually displaying the output frame rate
of the iScan – the motion will be very smooth. However, if the display is performing any type of frame rate
conversion there will be very noticeable stutter introduced in the smooth motion. There may also be other objectionable
artifacts introduced depending on how the display actually performs the conversion. These include tearing (top and
bottom portion of the bar are horizontally misaligned) and distortion.
75% Color
Bars
8F75 This is a standard full-height color bar pattern. There are 7 vertical bars across the screen at a 75% saturation level. From
left to right the bars are white, yellow, cyan, green, magenta, red, blue, and black.
100% Color
Bars
8F10 This is a standard full-height color bar pattern. There are 7 vertical bars across the screen at a 100% saturation level.
From left to right the bars are white, yellow, cyan, green, magenta, red, blue, and black.
10-100 IRE
Gray Window
I10 -
I100
This sequence of patterns consists of a centered, quarter-screen gray window. The gray level varies from 10 IRE to 100 IRE
in 10 IRE steps
Gray Ramp GRYR This test pattern is a horizontal gray ramp. There is a black level (0 IRE) vertical bar along the left of the pattern and a
white level (100 IRE) vertical bar along the right side of the pattern. Between the two bars is a monotonic gray ramp which
ranges from the minimum luminence level (i.e., blacker than black) at the left to the maximum luminence level (i.e., whiter
than white) at the right. The minimum level of the ramp is a 10-bit digital value of 4 (equivalent to an 8-bit value of 1);
the maximum level of the ramp is a 10-bit value of 1020 (equivalent to an 8-bit value of 254).
Coarse Cross-
Hatch
COAR This test pattern is a coarse cross-hatch, useful for convergence and geometry on CRT displays. It consists of a 75% white
level hatch with approximately 20 divisions across the width of the image.
Fine Cross-
Hatch
FINE This test pattern is a fine cross-hatch, useful for convergence and geometry on CRT displays. It consists of a 75% white
level hatch with approximately 40 divisions across the width of the image.
Focus FCS This test pattern is a regular array of small crosses, useful for focusing of CRT displays. It consists of a 75% white level
array of horizontal/vertical crosses with approximately 60 crosses across the width of the image.
Half-
Transparent
Black/White
HBW This test pattern has the left half of the image transparent (i.e., the left half of the current video source is displayed on
the left half of the image), with the right half of the image composed of a standard black level on the top half and a
standard white level on the bottom half. The black level is 0 IRE (10-bit value of 64, or an 8-bit value of 16) and the
white level is 100 IRE (10-bit value of 940, or an 8-bit value of 235). This pattern is useful for matching the black/white
levels of an input source to the reference black/white levels of the test pattern. If a display is first set up for black and
white levels using the iScan HD+'s test patterns (e.g., TP2, TP19), then each input source can be quickly and accurately
matched to these reference levels by visually comparing the video source image on the left half of the display to the ref-
erence test pattern levels on the right half of the display. The test pattern's black and white blocks are designed to match
up with standard test patterns available from hardware or software (e.g., DVD) test pattern generators.
Half-
Transparent
Color Bars
7H75,
7H10,
8H75,
8H10
These test patterns have the top half of the image transparent (i.e., the top half of the current video source is displayed
on the top half of the image), with the bottom half of the image composed of a standard set of color bars. These patterns
are useful for matching the color levels of an input source to the reference color levels of the test patterns. If a display is
first set up for color levels using the iScan HD+'s test patterns (e.g., TP7, TP8), then each input source can be quickly and
accurately matched to these reference levels by visually comparing the video source image on the top half of the display
to the reference test pattern levels on the bottom half of the display. The test pattern color bars are designed to match
up with standard test patterns available from hardware or software (e.g., DVD) test pattern generators. To ensure compati-
bility with a wide variety of color bar patterns, there are four different half-transparent color bar patterns available – 75%
color bars with 7 bars (white, yellow, cyan, green, magenta, red, blue), 100% color bars with 7 bars, 75% color bars with
8 bars (white, yellow, cyan, green, magenta, red, blue, black), and 100% color bars with 8 bars.
