000 micro-seconds after the Frame 1 readout begins (5,000 microseconds before the end of
the Frame 1 readout time) and the first WDR exposure (E1) begins 1,000 micro-seconds
before the end of Frame 1 readout. Finally, the 2

nd

WDR exposure (E2) begins 100 micro-

seconds before the end of the Frame 1 readout. In this example, two line artifacts may be
seen. These artifacts will be located where they occurred with respect to the readout of
Frame 1 in time. For the E1 exposure, the artifact may be seen at image line 150 (1000
micro-seconds before the end of the frame readout) and, for the E2 exposure, an artifact at
line 15 (100 micro-seconds before the end of the Frame 1 readout) maybe observed. If the
E1 and E2 exposures do not overlap with the readout of Frame 1, no artifacts will be
observed.

To eliminate these artifacts when trying to achieve maximum frame rates:



Enable the

Fixed Frame Period

control to increase the frame time slightly so

the WDR exposures occur after the frame readout ends. For example, if the
minimum frame time is 20ms (50 fps) and the longest WDR exposure desired is
2ms (so the WDR exposure occurs 2ms before the end of the frame time), then
use the Fixed Frame Period control to increase the frame time by 2ms to 22ms.



Use trigger mode, WDR image artifacts will never be present, because the
exposure and readout are not overlapped in triggered mode.

DATA OUTPUT FORMAT

2.12.1 Bit Depth

The  internal  digitization  level  within  the  image  sensor  can  be  varied  to  improve
frame rate. 10-bit digitization level allows the on-chip A/D converters to settle more
quickly enabling higher  frame  rates while 12-bit  digitization levels  provides  higher
dynamic range at the expense of frame rate. The camera can output the data in 12, 10
or 8 bit format.  In 8-bit  output, standard bit reduction process  is  used and  the least
significant bits are truncated

-

“12-bit” digitization (See Figure 2.12)

If the camera is set to output 12-bit data, the image sensor data bits are
mapped to D0 (LSB) to D11 (MSB) output bits.

If the camera is set to output 10-bit data, the image sensor most-
significant data bits [D2 to D11] are mapped to the D0 (LSB) to D9
(MSB) output bits.
