3nh TE183 A REFLECTANCE 14 horizontal and 19 vertical lines 19 / 14
– TV cameras GRID TEST CHART
A grid structure of 14 horizontal and 19 vertical lines is arranged
on a white background. The grid corresponds to a grid generated
electronically by a test generator. The grid structure also
corresponds to the ball structure of the T01 Geometry Test Chart.
The test chart is designed for operational adjustment and control
of TV cameras. The grid permits rough visual appraisal of scan
linearity and the lines serve the purpose of adjusting
The chart is available also with white lines on a black background.
The TE97 corresponds to the 4:3 part of the HDTV test chart TE117.
It is designed for measuring and quick (most visual) appraisal of
transmission characteristics of high resolution non-broadcast
In the center of the test chart on a gray background (D=0.75;
reflectance = 18%) a white circle with four gray scales of 11 steps
each is located. They are graduated in equal linear steps from
D=0.15 to D=1.65 and are used for checking halftone rendition of
cameras. Due to the white surrounding area the results may,
however, be qualified.
On both sides of this central circle four circles with resolution
wedges are arranged.
All frequency values in the test chart are indicated in cph (cycles
per height). In the central circle three resolution wedges with
different frequencies are arranged vertically and horizontally.
They reach from 100 to 250, from 200 to 500 and from 400 to 1000
cph. In addition, two resolution wedges angled in 45°generate
frequencies of 200 to 500 cph.
In the middle of the test chart and on the left and right sides
there are four squares with multi bursts that are inclined at
angles of 0°, 45°, 90°and 135 °generate a different frequency
(141.4 cph) in horizontal and vertical direction (due to their
inclination). The inner white and the four outer circles enable a
rough appraisal of the scan linearity. The outer ones show
cross-shaped resolution wedges. The circular rings, which can also
be used for checking geometry, are designed for marking the
resolution in vertical and horizontal direction. Resolution is
shown at 200, 300, 400, 600 and 800 cph.
In the center of the test chart both in the gray and the white area
bar elements are arranged with a length of 1 (= half the
picture-height), 2, 4, 8, 16, 32 and 64 cph. Left of the right
vertical gray scale.there are five additional short bars with 100,
300, 500, 700 and 900 cph.
All Imatest ISO 12233:2014 ESFR charts are fully compliant with
the ISO Low Contrast EdgeSFR test chart standard.
eSFR ISO charts are available in three versions:
1.Standard: basic, no extra measurement features, inkjet prints.
2.Enhanced: extra squares, wedges and color patterns when printed
with technologies that allow color. Inkjet and photographic print
3.Extended: similar to Enhanced, but with a 16:9 aspect ratio,
suitable for HDTV and cinema, inkjet prints.
Available sizes: 0.5 x 0.5 cm to 110 x 182 cm (5 x 5mm to 1100 x
Available Substrates: Matte, Semigloss, Backlit Media
(DisplayTrans), Photographic Paper, B&W or Color LVT Film, and
Chrome on Glass for high precision needs.
All Imatest charts can be customized to fit your testing needs.
Reflective Matte Color Spilled Coins Dead Leaves Test Chart for
measuring texture sharpness
The Color Imatest Spilled Coins chart (a variant of the Dead Leaves chart) for measuring texture
sharpness has several advantages over older Dead Leaves charts. Key
- The Scattered Coins pattern in the central region is almost
perfectly scale-invariant (unlike conventional dead leaves charts),
enhancing the accuracy and robustness of MTF measurements so they
correlate well with other methods (such as the slanted-edge) for
RAW images (which have no nonuniform or nonlinear processing).
- Maximum contrast range is 3:1, as called for in the CPIQ Phase 3
draft Texture Blur Metric draft specification.
- It is more uniform, i.e., is more shift-invariant than other Dead
- It contains slanted edges (2:1 and 4:1 contrast) for convenient
comparisons with the dead leaves pattern.
- The gray area to the left and right of the dead leaves pattern has
the same mean density as the dead leaves pattern, allowing it to be
used for effective noise PSD removal using the McElvain et. al.
- Registration marks and 16 grayscale patches are included. The
linear levels used to create the grayscale patches are 0 through
255 in steps of 17 (same as the Siemens Star chart in the draft of
the upcoming ISO 12233 standard).

SFRreg test target test Charts for measuring MTF and lateral
The SFRreg test target consists of a slantededge quadrant pattern
enclosed within a circle. It is used for measuring MTF and lateral
chromatic aberration. A test image typically contains several
targets that are automatically detected and analyzed by the SFRreg
SFRreg targets can be placed at arbitrary positions and angles to
accommodate a wide variety of test cases:
● Long distance tests where conventional charts would be
● Ultrawide Field of View tests (>180) where a flat target
cannot reach the outer field
● Autofocus tests where a single frame can contain several targets
placed at different distances.d
ITHDR36 High Dynamic Range Charts for measuring both camera and
sensor Dynamic Range
The target is well suited for measuring both camera and sensor
Range, which are fundamentally different. Measure the dynamic
range, tonal response and noise of HDR cameras with a single image
instead of multiple, exposure bracketed images. The chart contains
slanted edges for MTF measurements and gray background density to
enable proper exposure with automatic exposure cameras. The HDR
target has a density range exceeding 120 dB (optical density

Digital camera assessment is different from other products. It’s
unlike laptop and DIY which have a lot of software to test
objective data and everything can be seen from the data. However,
assessing the quality of digital camera not only needs certain
objective data, but also needs to combine actual operation and the
shooting proofs. Therefore, our assessment is based on the
principle of objective data and combined rational analysis from the
experienced reviewers to obtain the most objective assessment
