3. Light (50% gray or whiter) portions of the image must touch all four sides of the image.
Or else: IDEA Auto-SYNC may fail to recognize image boundaries. Images will be clipped
or there may be no image capture at all.
4. Wide solid black (3% gray or blacker) bars stretching across the entire image in any
direction should be avoided.
Or else: If composite video is not being used, the stripes may mimic composite sync
information. IDEA Auto-SYNC is very resistant to this type of mistake but not completely
immune to it. Images will appear scrambled.
5. Include many edges (as with text, fine stripes or a checker pattern).
In addition to the criteria listed above, future enhancements to IDEA
Auto-SYNC may be able to take advantage of other image characteristics. If you are developing a
standard test pattern for IDEA Auto-SYNC for long-term use, the pattern should include sharp
pixel transitions from light to dark and dark to light. A pixel transition is considered "sharp" if the
change in gray-scale from one pixel to the next (to the left or right) exceeds 50% of the full black
to white range. Including test or vertical or near-vertical fine grill patterns in the image would
suit the purpose.
