SineImage YE0237 High Resolution Sector Star Test Chart
| Material | Film or HD photographic paper |
The sineimage YE0237 high resolution sector star test chart serves for checking resolution over the whole picture area.
The test chart consists of three rows of three complete and two half sector stars of 72 (black and white) sectors. The stars are marked with three white circles which indicate resolution. This also applies to the outer diameter and the inner unresolved white circle. The marked resolution are (beginning with the outer diameter):
outer diameter 50 cph 100 TV lines
first circle 100 cph 200 TV lines
second circle 200 cph 400 TV lines
third circle 400 cph 800 TV lines
unresolved circle 1000 cph 2000 TV lines
The chart has an aspect ratio of 4:3 but additional markings for 16:9 between the stars in the first and third row. Because the chart is used especially for HDTV the height of the cph measure relates to the 16:9 aspect ratio.
Resolution measurement with TV lines is independent from TV standard.
