ELECTRONIC STILL PICTURE RESOLUTION CHART 16:9(ISO 12233)

                                              REFLECTANCE

The TE170 is designed to measure resolution of still cameras.

It contains resolution wedges up to 2000 lines per picture height. Furthermore it contains

slanted edges for SFR measurement.

On the test chart marks for the respective picture size are arranged (square = 1:1; usual

digital format = 4:3, small picture = 3:2 etc.). The camera has to be adjusted that the

whole picture height is captured an the appropriate picture proportion is seen. The

numbers at the lines each mean “lines/picture height x 100”; e.g. 12 = 1200 etc. Thus

evaluation of a camera is possible with the aid of the horizontal and vertical lines.

The specified resolution should be the value in the center of the picture on optimal

conditions. Thus the quality of lenses, sensor and image computation is evaluated

simultaneously.

With open iris end extreme zoom position the result can be worse. This has to be

tested and noted separately in the test report. Important is the separate evaluation

of resolution in the picture corners.
