6.4 Rolling Shutter Readout
NOTE:
All timing diagrams incorporate rising edge triggers.
The Expose Out I/O signal goes high only when all rows within a single frame are being
exposed simultaneously. The length of the Expose Out signal is equal to the time
between the start of the last row's exposure and the end of the first row's exposure. This
is also equal to the exposure time configured in LightField provided the exposure time is
greater than the readout time.
With Rolling Shutter mode, there are two timing scenarios:
• Exposure Time < Readout Time
Figure 6-2 illustrates the timing diagram for this mode.
