3.Terms and definitions
a) Resolution resolution Apart from the jagged, and distinguished fine pattern to the limit. Expressed in per unit height of the frame number.

4. Test chart
4.1 ISO12233Resolution test card
This standard to 12233On the basis of ,Test chart (Figure 4.1,Hereinafter ISO Chart) also directly use ISO12233Using charts. ISO Chart contains a variety of styles, the standard (Visual resolution) which is mainly used in horizontal direction J1, K1; Vertical direction J2, K2; Tilt 45Degree directions JD , KD And other styles. (ISO12233Recorded in the 3Types of measurement methods, ISO Chart of the procurement methods, please refer to 9. About 12233. ) ISO Charts, not necessarily directly using the chart. You can also cut out must be part of the arranged and partitions using
ISO12233Mainly by the United States Sine Patterns Company and Applied Image Company and Japan production
4.2 ISO Recorded in the chart number means
Photography, to the effective height of the chart (horizontal long side pictures 4.1Height of the rough inside of the box when) fill the screen ,Patterns figures *100Height of the picture in each unit .When shooting is not necessarily to make effective height to fill the screen ,You want calibrate.

ISO12233Test target test, each test unit test coverage

1: Unit tests:

Mainly use the horizontal J1, K1; Vertical direction J2, K2; Tilt 45 Degree directions JD , KD Styles, there are four cross area.

2: Each test unit test coverage:

J1, K1: Used to measure levels of Visual resolution, with 100~2000LW/PH Test coverage;

J2, K2: Used to measure vertical video resolution, with 100~2000LW/PH Test coverage;

JD , KD : Used for measuring inclined 45Visual resolution, with 100~1000LW/PH Test coverage;

Four cross-test units: used to measure the corners of the horizontal and vertical resolution, with 100~1000LW/PH Test scope.

Using software for reading

According to CIPA Standard, you can use the software HYRes Judge limits resolution

Use HYRes Method of reading:

a. Use HYRes Software, open a picture, cut out of the reading area. When selected, click Trim Execute.

Note that the reductions required prior to selecting the correct line (Wedge Type ) And direction (Direction)
