ISO 12233 — Picture resolution test chart Download Author：admin Date：2016-10-21 Hits： The Picture resolution test chart is designed to measure resolution of still cameras.

  1. Resolution Test Charts 1. Introduction In the reviews of digital cameras published by several organisations including DPREVIEW there is considerable variation between the resolution measurements which have been derived for the same camera model using the ISO 12233 test chart. As discussed here that is.

  • MTF Mapper is a really helpfull tool to check optical performace of lens-sensor-systems. Also the background information provided are going deep into the topic.

  • Wonderful program. I use this all the time to compare lens resolutions and calibrate them in a scientific way. Really helped with my new Sigma 150-600 and its USB dock to calibrate 4 focal lengths and 4 distances per focal length. You rock, Frans! I'd appreciate a more detailed description of the 'annotated' edge photo labels, e.g. yellow '0.10 (0.50)' versus green '0.10 (1.00)' versus blue.

  • Generates Edge Spread Functions, Line Spread Functions, MTF/OTF Spatial Frequency plots from slanted edges - and much, much more. No installation required, but ability to work in Command Line necessary for Windows executables. Highly recommended!

Resolution Chart

We use our resolution chart to help assess a camera's ability to resolve detail.

Eye Test Chart

We shoot the chart at every sensitivity (ISO) setting and examine the images closely on the computer screen. We show a cropped section of the images in our reviews, but the full images can be downloaded via the hyperlinks.

In the above example from the Olympus E-P3 the score would read 24 (see full image)

The cropped section shows the part of the chart that tests the camera's vertical resolution (ability to see fine detail) at the centre of the frame. The figures in the image captions give a measure of the camera's performance in line widths per picture height x100. The higher the value, the better the detail resolution and the better the camera's performance.

Images are primarily assessed at 100% on the computer screen, but it may be necessary to zoom in and out to determine the resolution limit properly.

With some cameras the resolution limit is the point beyond which the lines merge into each other to form a broad grey strip. Sometimes it may not be immediately apparent that two or more of the lines have merged, giving the appearance of detail even though a little has been lost. With other cameras interference patterns develop when the resolution limit is exceeded and these obscure the resolution lines.

Our resolution chart is based upon ISO-12233 and is supplied by Applied Image Inc. This chart is suitable for use with a variety of digital camera formats including full-frame, APS-C, Four Thirds and Micro Four Thirds.

Where possible (and unless stated otherwise) we use the Sigma 50mm f/1.4 EX DG HSM with the appropriate mount on the camera to minimise variables and ensure that images from different cameras are comparable. Final fantasy 7 hd mod.
