What is an ISO 12233 Chart?

The ISO 12233 Chart is the I3A/ISO standard for measuring the resolution of electronic still imaging cameras. The chart I am using is a very expensive, finely printed variation of the ISO 12233 standard that extends resolution to 4,000 lines per picture height (l/ph) and features other benefits as well. This chart serves as a good visual indicator of sharpness as well as CA (Chromatic Aberration) and distortion.

Application

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.

The following is a complete product line:

Enhanced Version

Enhanced Version

The Imatest Enhanced ISO 12233:2014 E-SFR chart has all the features of the Standard chart, keeping the 3:2 aspect ratio, with the addition of six added slanted squaresfor measuring performance near the image boundaries and hyperbolic wedges for visual analysis or analysis with the Imatest Wedge module. It also has 16 color patches when produced with technologies that allow color. Since these additions are in regions of the chart not covered by the standard, compliance with the standard is unaffected.

The differences between the Imatest charts and the chart illustrated in the standard are listed below. Even with these differences the Imatest chart is in full compliance with the standard.

  • A 20 patch OECF grayscale pattern* is used as opposed to the 16 patch version.
  • The Focus Patterns in the centers of the squares are rectangular (to increase the MTF measurement area) and are designed to reduce interference with automatic edge detection.
  • There are four registration marks instead of three to facilitate automated region detection. (Four features are required for a projective transform.)
  • An additional mark above the lower-left registration mark is used for detecting chart orientation.

The differences between the Enhanced and Standard Versions are as follows:

  • Six extra slanted squares are added for measuring performance near the image boundaries.
  • Several hyperbolic wedges with spatial frequencies, similar to the CIPA chart referenced in the ISO standard, for visual analysis or use with the Imatest Wedge module.
  • 16 color patches when produced with technologies that allow color (inkjet or color LVT), with colors similar to the industry-standard 24-color test chart.

This chart will work with the fully-automated eSFR ISO module.


The values of the 11-graduated gray scale are as follows:


StepDensityReflectance in %
10.0589
20.1374
30.2260
40.3248
50.4337
60.5528
70.6920
80.8813
91.068
101.315
111.652

The density values are based on BaSo4 = 0. Two black fields and a white field are located between the gray scales, the density of the black filed is D > 2.4 (reflectance < 0.5 %). The density of the white filed is D = 0.05 (reflectance = 89.9 %).
