3. Repeat steps 1 and 2 for all formats and test images. Use the following guidelines to

verify proper operation:

When testing photometry such as chrominence, use the

ColorBar

,

SMPTE133

, or

SMPTEbar

images. Look for missing bars which may indicate a dead or

unconnected channel. Also, look at the transitions between the bars; they should
be sharp and distinct. Each bar also should be uniform in color and intensity across
its entire width.

When testing luminance, you can use the

SMPTE133

(grayscale) images. To test

gamma correction, you can use the

SMPTE133

(checkerbox) image. The detailed

methods for verifying these parameters on the

SMPTE133

image are provided in

Appendix B, “
