ISO12233 2000 Edition Resolution Test Chart Standard Security Monitoring Target

ISO12233 2000 Edition Resolution Test Chart Standard Security Monitoring Target

This resolution chart is an adaptation of the features of the ISO12233 standard to higher aspect ratios and also includes higher resolution features.

Note that this chart does not conform to the new ISO 12233:2014 standard, released in February, 2014 (although an image is included in the standard for reference). We recommend the ISO 12233:2014 E-SFR chart for new work that does not specifically require the old chart.

Details


Notes: This chart is used to measure sharpness from slanted-edge patterns (as Spatial Frequency Response = SFR) using the Imatest SFR module. It can also measure resolution from the hyperbolic wedges using the Imatest Wedge module (a part of Rescharts).

General Description: This test pattern is an image evaluation tool for determination of resolving power, limiting resolution and spatial frequency response (SFR) in digital CINE imaging.

Image Description: Adapted from the ISO-12223 test chart for use with imaging systems having higher aspect ratios, this target includes all features specified in the ISO-12233 standard with the following additions or modifications. (For reference, please refer to the ISO-12233 standard document.)

•Star sector targets added in two places cover a range of 150 to 2000 line widths per picture height. (¼ to 3⅓ cy/mm)

•Dual-frequency zone plates on a black square background with hyperbolic wedges in a vertical orientation allow evaluation at 500 to 2000 lw/ph vertical resolution.

•Checkerboard patterns rotated to 45 degrees and made up of squares having 1.5 mm edge length (200 lw/ph) aid in focus and evaluation of aliasing.

•Additional framing arrows are included to define aspect ratios out to 2.4:1.

•This target’s overall size is equivalent to exactly three times that of the ISO12233 standard 1X target.

Image Forming Material: Photographic emulsion

Polarity: Positive image features

Image Contrast: 40:1 typical

Terms: Line widths per picture height (lw/ph); resolution features on this chart are labeled in line widths x 100 per picture height. Note that each line transition is counted.

Guidelines for Usage: This document is not intended to replace the International Standard Document ISO-12233. However, the following guidelines will aid the first use of this chart.

•The chart should be illuminated uniformly (±10% of center luminance) against a surround of low reflectance and with a minimum of flare light. The illuminant should be effectively neutral with respect to either daylight or tungsten illuminants (ISO-7589). Camera white balance should be adjusted to provide equal red, green and blue signal levels.

•The camera should be positioned to provide centered, full-frame-height rendering of the chart’s active area. Use the chart’s framing arrows and horizontal edges to aid positioning. The camera to test chart distance should be noted.

•Achieve good focus using the chart’s zone plate feature(s).

•Set camera lens aperture and exposure time to provide maximum signal from white areas while avoiding any signal clipping.

•Where possible, image compression features should be disabled.

•Camera output signal should be linearized using the standard reflection camera OECF (Opto-Electronic Conversion Function) test chart.

•Line width features can be viewed with any file viewer for an indication of the visual resolution limits of the device. International Standard Document ISO12233 contains instruction regarding a quantitative determination of resolution limits. Visual and limiting resolution values should be reported in values of lw/ph.

•Slant-edge features can be analyzed using SFR software freely,this topic is also described in greater detail in the International Standard Document ISO-12233.

•Aliasing level is determined using the slanted burst patterns. It is quantified for each frequency by the ratio of the maximum minus minimum responses divided by the difference of average maximum minus average minimum within each frequency burst.
