Case 1 - Exposure Start With Frame Valid High
Figure 3-4: ExSync, Level-controlled Mode - Exposure Start with Frame Valid High
If the ExSync signal falls while frame valid is high as shown in Figure 3-4:
• The actual start of exposure can be up to 65 µs later than the fall of the ExSync signal.
(This is commonly referred to as an exposure start jitter.)
• Due to the jitter, you may find that the actual length of the exposure time decreases even
though you increase the length of the ExSync signal low time, or that the exposure time
increases even though you reduce the length of the ExSync signal low time.
• The actual length of the exposure time will be equal to the ExSync signal low time plus /
minus the jitter time.
As shown in Figure 3-4, FVAL must be low for at least 1 µs before the ExSync signal
rises.
