Synchronization Modes with Variable Exposure Time
T
pix
: Timing Pixel. During this uncompressible period, the pixel and its black reference are read out to
the Digital converter. During the first half of this timing pixel (read out of the black reference), we can
consider that the exposure is still active.
Digital Conversion
:
During the conversion, the analog Gain is applied by the gradient of the counting
ramp (see next chapter : Gain & Offset). The conversion time depends on the pixel format :
>
8 or 10 bits :
6µs
>
12 bits :
24µs
This conversion is done in masked time, eventually during the next exposure period.
T
d
: Delay between the Start exposure required and the real start of the exposure.
