Andreas,
Why do you need pulse _before_ trigger? With this senor exposure of the
first line start 8 scan lines after the trigger, last line exposure starts
1/15 sec later. So if you want to use a flash, you need to set the exposure
time 1/15 sec and trigger flash 1/15 after the trigger.
The FPGA
Andrey,
In fact we develop a led light and not a discharge flash, therefore the
light isn't deposited in a short period. You say the exposure of the
last scanline starts 67ms after the first line. I'm trying the get light
intensity high enough for an exposure time of 5ms. This means that the
leds

Andreas,
that depends on what are you trying to capture. If ERS distortion is not a
problem in your case, and the LED is just to provide more light, not limit
the exposure - yes, you can do that (same as if LEDs were always ON for the
camera). If on the other hand, you need LED as a snapshot

Hello,
First, please let me introduce our use case; we are trying to use Elphel
cameras (353 + Computar 4-8mm 1/2) to get maximum resolution ( FullHD), 25
fps video.
Our current problems are about image quality
