3nh ISO 12233:2014 standard esfr test charts with ISO Low Contrast
All 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

3nh iso 12233 resolution test chart (0.5x,1x,2x,4x,8x)
Resolution test chart is the standard proof which can provide aided
testing for vertical resolution and horizontal resolution of actual
Resolution test uses ISO 12233 resolution test chart and adopts
unified shooting angle and environment.
The calculation of resolution test uses HYRes software, and the
calculation will be done in two parts: vertical resolution and
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
ISO 12233 resolution test chart is in accordance with ISO 12233
standard “Photography- Electronic Photographic Image-Measurement”.
In active area of 1x size, the error is only 0.1mm when measuring
the height of 20cm. It has almost all the characteristics of most
