Quick Overview

The ISO Camera Resolution Chart conforms to the ISO-12233:2000 standard, "Photography-Electronic still picture cameras - Resolution measurements". Hyperbolic wedges for resolution evaluation range from 100 - 2000 lines per picture height. Other features include checker patterns, multiple slant-edge lines, a center-focus zone plate and framing marks for 1:1, 4:3, 3:2, and 16:9 aspect ratios.

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.

* Required Fields



  • Active Area: Charts are available in two sizes. It is recommended that the smaller charts be used to test imaging systems with sensors up to 8 MP, and the larger charts be used for testing of sensors above 8 MP.
    • The smaller chart has an active area of of approximately 22 X 39 inches and is printed on 24 x 40 inch paper.
    • The larger chart has an active area of approximately 33 X 59 inches and is printed on 40 X 60 inch paper.
  • Paper/ink type: Semi-gloss OR Matte. Matte paper/ink can be used to reduce reflected light, but is slightly less sharp than semi-gloss paper. Semi-gloss paper/ink is recommended for most applications.

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).
