ISO 12233 Digital still-camera resolution chart - Inkjet on Paper
- 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).
