I have a scenario where I am trying to see whether an IR led has flickered on. This flicker can be as short as 6ms. When I set the framerate of the depth camera, I can only set the exposure up to a specific value "less than" the exposure. So for example, when I try to set the frame rate to 30fps or (1/30) * 1000000 = 33333 microseconds, the camera will only allow me to set the exposure less than that up to 32200 microseconds before dropping the frame rate on my behalf to 15fps. So to be clear, 32201 will cause my frame rate to drop to 15fps although I set it to 30fps which is a difference of 1133 microseconds. I am pretty sure I am getting about 6ms of flicker from my IR led who's exposure time is 6000 microseconds but I am in fact not detecting the flicker in my image frame. I experience this regardless which frame rate I set it at with the corresponding maximum allowed exposure(90, 60, 30, 15). I have experienced that this is the case with the 455 and 415 which confirms the issue exists with both global and rolling depth shutter. Is there an inherent limitation on the hardware or software that will not allow me to get complete exposure at the frame rate?
