ISO­compliant SFRplus test charts work with all Imatest software to provide automated, comprehensive image qualit

Imatest’s ISO­compliant SFRplus charts are designed to work with all Imatest software to provide automated, comprehensive image quality analysis. SFRplus charts:

●Test for MTF, noise, lateral chromatic aberration, dynamic range, among many other image quality factors.

●Maximize the use of available chart space compared with standard ISO charts.

●Reduce clipping of high­contrast edges to increase accuracy and consistency including better overexposure and underexposure testing performance.

●Contain added signal processing measurement information like sharpening and noise reduction.

●Support automated region detection to identify regions of interest without manual input.

Available sizes: 0.5 x 0.5 cm to 110 x 182 cm (5 x 5mm to 1100 x 1820 mm)

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. Please contact your reseller for details.

This chart has 36 low-noise density patches with density steps of approximately 0.1, for a density range of at least 3.2 (density from base to base + 3.1 minimum). A nearly circular patch arrangement ensures that vignetting has minimal effect on results. A CSV reference file with actual densities will be supplied. The chart has an active area of 197x235 mm (7.75x9.25 inches) on 203x254 mm (8x10 inch) film.

It also contains slanted edges in the center and corners with 4:1 contrast for measuring MTF. The edges have an MTF50 >= 16 cycles/mm, which is about 3 times better than the best inkjet charts. Registration marks make the regions easy to select. A neutral gray background helps ensure that the chart will be well-exposed in auto exposure cameras (compared to charts with black backgrounds, which are sometimes strongly overexposed).

It is supported by Stepchart, Multicharts, Multitest and can be used with the Dynamic Range postprocessor if several manual exposures are available. Dmax >= 3.4 is sufficient for camera phones and digital cameras with small pixel sizes, but high-end DSLRs generally have higher dynamic ranges (and also manual exposure), which makes them well suited for Dynamic Range.

This chart is produced with a high-precision LVT film recording process for the best possible density range, low noise, and fine detail.

LVT Targets with reference files are guaranteed to remain accurate for one year from first use. After this time the targets can be returned for re-calibration and will be returned with a new reference file.

ISO 12233:2014 E­SFR test charts with the ISO Low Contrast EdgeSFR test chart standard

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 options.

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 1820 mm)

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 features:

  • 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 Leaves charts.
  • 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. technique.
  • 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 chromatic aberration

SFRreg Charts:

Required Description:

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 module.

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 impractically long

● 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

Required Description:

The target is well suited for measuring both camera and sensor Dynamic
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 >6.0).

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 shooting.
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 horizontal resolution.
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 results.
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 resolution charts.
