Very interesting, from Hermann SW (minimal shutter time is per line):
Wrong, minimal shutter time is the time it takes to capture a single row.
That is maximal for highest imx477 resolution, and for that it is 0x5dc0=24000ns=24µs
Then according to my calculation for the HQ sensor at 4056x3040 and 0x5dc0=24000ns a frame=3040x24000ns=72.96ms => 13.7 fps should result.
With GScam at max. 1456x1088p60, that would be 1/(1088*60)=15318.6 ns per line. A maximum of 510 fps should then be possible with 128 lines. Does the width then have no influence at all on the fps? Then 1456 pixel width should also be possible with 128 lines at 510 fps, or have I misunderstood something?
