ISO12233: 2014 eSFR resolution test card

　　SineImage eSFR resolution test card with the software can automatically calculate several key image quality factors including sharpness, horizontal color, tone response, color reaction and noise.

　　And the low contrast Edge SFR specification is fully compatible with the new standard ISO 12233: 2014 replaced by the 2000 standard, because the previous use of high-contrast test chart can easily lead to out of bounds or measurement errors, but also the lack of progressive group assessment system tone response, and Only a small number of features are available for automatic analysis.

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

　　The test card has the following three versions:

　　Standard Edition: Basic functionality

　　Enhanced version: Added extra square, wedge and color pattern

　　Extensions: Similar to the enhanced version, just extended to 16: 9 for HD movies and movies

　　At present we are all inkjet printing production eSFR resolution test card, enhanced version is photographic mode printing. All Sine Image ISO12233: 2014 eSFR resolution test cards are fully compliant with ISO standards. Imatest's eSFR ISO module provides a highly automated test analysis test card.

　　Standard Edition

　　ISO12233:2014 eSFR分辨率测试卡简介

　　SineImage eSFR分辨率测试卡配合软件可以自动计算几个关键图像质量因素包括锐度、横向色差、阶调反应、色彩反应及噪点。

　　与低反差 Edge SFR 规格完全相容，新的标准为 ISO 12233:2014取代了2000标准，分辨率测试卡因为之前使用高反差测试图容易引起出界或量度误差，也缺少渐进组别评定系统的阶调反应，并且只有少量功能适用于自动分析。

　　SineImage eSFR分辨率测试卡的设计基于ISO 12233:2014 定义的低反差edge SFR规格。

　　测试卡有以下三种版本：

　　标准版：基础的功能

　　增强版：增加了额外的正方形、楔形和色彩图案

　　扩展版：类似于增强版，只是扩展到16:9，适用于高清电影和电影

　　目前我们都是喷墨打印制作eSFR分辨率测试卡，分辨率测试卡增强版本是照相模式打印。所有Sine Image的ISO12233:2014 eSFR分辨率测试卡是完全符合ISO标准的。Imatest的eSFR ISO模块提供高度自动支持检测分析测试卡。

　　标准版

　　ISO12233: 2014 eSFR resolution test card Standard Edition is 3: 2 aspect ratio. In order to meet more testing requirements we have added enhanced and extended versions, enhanced and expanded versions at the edge of the image to increase the performance of the box for testing, hyperbolic and color blocks. These cards are fully compliant.

　　ISO12233: 2014 eSFR is similar to the low-contrast E-SFR test card produced in accordance with Section 6.1 and Appendix C of the ISO standard document. But there are a few different. Here are their different comparisons:

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

　　(2) The square focus pattern of the center area of the test card is at right angles (in order to increase the measurement area of the MTF), the purpose of this design is to reduce the automatic detection of edge interference.

　　(3) has four focus marks, replacing the original three to help automate the area detection.

　　(4) There is an additional mark on the lower left of the focus mark to detect the direction of the chart.

　　This test card for the automatic eSFR ISO module, Imatest 4.0 version added this module.

　　Enhanced Edition

　　ISO12233:2014 eSFR分辨率测试卡标准版是3:2的长宽比。为了满足更多的测试要求我们增加了增强版和扩展版，增强版和扩展版在图像边缘增加了用于测试性能的方块，双曲线以及色块。这些图卡是完全符合标准的。

　　ISO12233:2014 eSFR类似于依据ISO标准文件的6.1章节和附录C制作的低对比度的E-SFR测试卡。但是却又有几点不同。下面是它们的不同对比：

　　(1)20阶OECF灰阶块取代了原先的16阶

　　(2)测试卡中心区域的方形聚焦图案是直角的(为了增加MTF的测量区域)，这样设计的目的是为了减少自动检测边缘的干扰。

　　(3)有四个对焦标记,替换了原先的三个帮助自动化区域检测。

　　(4)在左下方的对焦标记上面有一个附加记号用于检测图表方向。

　　这种测试卡用于全自动eSFR ISO 模块，Imatest 4.0版本添加了这一模块。

　　增强版

　　The enhanced version of the 2014 eSFR test card has all the features of the standard version, also the 3: 2 aspect ratio. Add six slanted squares at the edge of the image for testing performance and increased hyperbolicity for visual analysis or analysis on Imatest's hypotenuse module. Also added 16 patches. These increased areas are not covered by the standard, but do not affect compliance. The difference between the Enhanced and Standard Edition is as follows:

　　(1) Six additional squares are added to the edge 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 of the Imatest software.

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

　　This version of the resolution test card for the automatic eSFR ISO module, Imatest 4.0 version added this module.

　　Extended version

　　增强版的2014 eSFR测试卡有标准版的所有功能，也是3:2的长宽比。在图像的边缘增加了6个倾斜的方块用于测试性能和增加了双曲线用于视觉分析或者在Imatest的斜边模块上分析。也增加了16个色块。这些增加的区域没有被标准覆盖，但是并不影响符合标准。增强型和标准版之间的不同如下：

　　(1)在图像的边缘增加了六个额外的倾斜方块用于测试性能。

　　(2)几个空间频率的双曲线，类似于参考ISO标准的CIPA，用于视觉分析或者在Imatest软件的斜边模块分析。

　　(3)增加了16个色块(喷墨或者色彩LVT)，色彩类似于工业标准24色卡

　　这一版本的分辨率测试卡用于全自动的eSFR ISO模块，Imatest 4.0版本添加了这一模块。

　　扩展版

　　The extended version of the ISO12233: 2014 eSFR resolution test card contains all the features of the enhanced version (6 squares, hyperbolic and 16 patches), but extends to a 16: 9 aspect ratio. 16: 9 is intended for use in high-definition televisions and movies (also satisfying the camera's required 3: 2 aspect ratio). It also meets the standard.

　　This version of the test card for the automatic eSFR ISO module, Imatest 4.0 version added this module.
