Introduction to ISO12233: 2014 eSFR resolution test card

The SineImage eSFR resolution test card with software can automatically calculate several key image quality factors including sharpness, lateral chromatic aberration, tone response, color response, and noise.

Fully compatible with the Low Contrast Edge SFR specification, the new standard is ISO 12233: 2014 replacing the 2000 standard, because the previous use of high contrast test charts tends to cause out-of-bounds or measurement errors, and lacks the tone response of the progressive group evaluation system, Only a few features are available for automated analysis.

The design of the SineImage eSFR resolution test card is based on the low contrast edge SFR specification defined by ISO 12233: 2014.

There are three versions of the test card:

Standard Edition : Basic Features

Enhanced : Added additional squares, wedges, and color patterns

Extended version : Similar to the enhanced version, but expanded to 16: 9, suitable for HD movies and movies

At present, we are making inkjet printing eSFR resolution test cards, and the enhanced version is printing in photo mode. All Sine Image ISO12233: 2014 eSFR resolution test cards are fully ISO compliant. Imatest's eSFR ISO module provides highly automated support for inspection analysis test cards.

Standard Edition

ISO12233: 2014 eSFR Resolution Test Card Standard Edition

The standard version of the ISO12233: 2014 eSFR resolution test card is an aspect ratio of 3: 2. In order to meet more testing requirements, we have added enhanced and extended versions. The enhanced and extended versions add squares, hyperbola, and color blocks for testing performance at the edges of the image. These graphics cards are fully compliant.

The ISO12233: 2014 eSFR is similar to the low-contrast E-SFR test card made in accordance with ISO Standard Document 6.1 and Appendix C. But there are a few differences. Here are their different comparisons:

(1) The 20th-order OECF gray-scale block replaces the original 16th-order

(2) The square focusing pattern in the center area of the test card is right-angled (in order to increase the measurement area of the MTF). The purpose of this design is to reduce the interference of automatic detection edges.

(3) There are four registration marks, replacing the original three to help automate area detection.

(4) There is an additional mark above the registration mark at the bottom left for detecting the chart direction.

This test card is used for the fully automatic eSFR ISO module, which was added to Imatest version 4.0.

Enhanced Edition

ISO12233: 2014 eSFR Resolution Test Card Enhanced

The enhanced version of the 2014 eSFR test card has all the features of the standard version and also has an aspect ratio of 3: 2. Added 6 slanted squares at the edges of the image for testing performance and added hyperbola for visual analysis or analysis on Imatest's hypotenuse module. 16 color patches have also been added. These additional areas are not covered by the standard, but do not affect compliance. The differences between enhanced and standard editions are as follows:

(1) Added six additional oblique squares at the edges of the image for testing performance.

(2) Hyperbolic curves of several spatial frequencies, similar to CIPA with reference to the ISO standard, for visual analysis or analysis of the hypotenuse module in Imatest software.

(3) Added 16 color blocks (inkjet or color LVT), the color is similar to the industry standard 24 color card

This version of the resolution test card is for the fully automated eSFR ISO module, which was added to Imatest 4.0.

Extended version

ISO12233: 2014 eSFR resolution test card expansion board

The expanded version of the ISO12233: 2014 eSFR resolution test card contains all the features of the enhanced version (6 oblique squares, hyperbola, and 16 color patches), but the ratio is extended to a 16: 9 aspect ratio. 16: 9 is for HDTVs and movies (also 3: 3 aspect ratio required by cameras). It also meets the standards.

This version of the test card is for the fully automated eSFR ISO module, which was added to Imatest version 4.0.

ISO12233: 2014 eSFR Resolution Test Card Help

In the test chart, there are nine inclined rectangles with a contrast ratio of 4: 1. The OECF progressive group is used. The sides of the inclined rectangle can be used to test the spatial frequency response and lateral chromatic aberration.

The 20-level gray-scale OECF pattern surrounds the center of the chart to measure the tone response, gamma, white balance, and noise characteristics of the imaging system, to measure the average arrangement of plate radioactivity, and to reduce the measurement error of light drop. The noise test series covers a wide range, including density, scene-referenced original pixel noise, and ISO 15739 visual noise, signal-to-noise ratio, and dynamic range.

SineImage provides two additional versions of the eSFR test chart, which use extra space to optimize and extend the test chart beyond the standard. There are six additional oblique rectangles to measure the sharpness outside the imaging area.

According to another part of the ISO standard, four pairs of hyperbolic wedges were added to test the extreme resolution and moire.
