If I turn on the IR LEDs on my H7 (default sensor and lens), the live preview image in the IDE loses practically all contrast. It’s a wash of gray showing just the barest ghost of an image of the scene (if I point at literal lights or the computer screen, the image comes through, although washed out). Now, the initial suspicion would be that the sensor is EXCEEDINGLY sensitive to IR and that I the LEDs are actually blowing the sensor out of the water.
But that can’t be the case. First of all, my M7 behaves normally, with the IR LEDs simply brightening up the image a little bit. But it has a different sensor, so that could explain the difference. They also have different LEDs, so again, maybe that’s the difference.
But I left the H7’s LEDs off and then pointed the M7 at the scene with its LEDs on, and the H7 preview image didn’t go to hell. It was just slightly brightened by having the M7’s LEDs pointed at the scene. But still, one could argue that the H7’s LEDs are insanely more powerful, so maybe that’s the explanation.
But then I turned on the H7’s LEDs and the live feed, once again blowing out the image, and then covered the LEDs with my fingers, careful to do a good job really covering them up. And the image did not improve. Pointedly, even if a little IR light was leaking out, the image didn’t improve a little bit, to be honest. At this point, I’m convinced there is a hardware or software error occurring. This error only seems to occur with the IR LEDs. The RGB LEDs (or three color single LED, whatever it is) doesn’t do this.
Is the circuit to the IR LEDs (which are physically a different object than the RGB LED) doing something to the sensor circuit?
I’ve attached some screenshots.
