Dear Kaien, How do you change the exposure? a) camvc ui? b) parameters editor (parsedit)? where you need to set ProgramAhead from 3 to 0. c) calling a function in php or C? like "elphel_set_P_arr($parsForRaw, $thisFrameNumber)" which when called with one parameter elphel_set_P_arr($parsForRaw) affects the 3rd frame by default. A php example can be found in the "raw.php".
Also you can can check the exposure changing more precisely if you: 1) go to parsedit->check autoexposure and follow View/Edit Current<%20http://192.168.0.9/parsedit.php?title=Parameters+for+groups:+autoexposure+&EXPOS&AUTOEXP_ON&AUTOEXP_EXP_MAX&AEXP_FRACPIX&AEXP_LEVEL&HDR_DUR&HDR_VEXPOS&AE_THRESH&AE_PERIOD&HIST_DIM_01&HIST_DIM_23>link. 2) mark the "Test" checkbox (if it's not there change the EXPOS parameter for example) 3) when Test is checked - change the EXPOS once more and follow the Last acquired images<http://192.168.0.9/parsedit.php?images=9:3:0.200000&done=91891/COMPRESSOR_RUN:2/91893/EXPOS:13000/91895/COMPRESSOR_RUN:0/>link where you can find out to what image exactly the change had effect on since COMPRESSOR_RUN state 0x2 (try different ProgramAhead values).
