No, sorry, I don't mean exposure value, by "external exposure" I meant the EXPOSURE pin. But in fact, as I see now, it is just another name for the TRIGGER pin:( But what we do have on some sensors, e.g., on MT9T031. On mt9t031 they distinguish between the beginning of the shutter sequence, the exposure and the read sequence, and depending on a parameter they decide which signals to use to start which action. > Are there any public datasheets that you know of on these? I think, I just searched for mt9t031 and found a datasheet somewhere in the wild...
