Moin,
Just wanted to ask if someone is already experience with LED lights (as eg used for concerts), since in my case the light is dimmed occur Rolling Shutter (ExomorR CMOS chips).
Is it Led lights which can be dimmed without experiencing the rolling shutter? [100% light (color) occur at any Rollings]
thx
Xinon
Antwort von Büschel:
What makes you think that the RS-trigger LEDs Effect? That has nothing to do, the RS-effect is due to the fact that the sensor is read too slowly.
The LEDs flicker very high frequency, that is the case. The human eye does not see (some of it can supposedly), the camera already ...
When the RS-Lighting Effect at full does not occur, it is rather to the fact that is caused by a shorter read faster shutter speed of the sensor.

Thank you for the quick reply.
What makes you think that the RS-trigger LEDs Effect? That has nothing to do, the RS-effect is due to the fact that the sensor is read too slowly. How do I know? Because I have described the rolling shutter wrong. Sorry. It's about to black stripes which run through the picture (as before the filming of monitors). It is not dependent of the brightness as ambient light (or is conventional lights) to see still normal.
At the same time - the effect only occurs in CMOS cameras on ...
Thus, it is probably s.der combination of CMOS and LED headlamps.
The LEDs flicker very high frequency, that is the case. The human eye does not see (some of it can supposedly), the camera already ... I've already seen flickering LED synonymous Banks;) - but that is where my problem really begins / my question. Who has experience with LED headlamps and CMOS cameras? For it is not only the dim, they are synonymous, the gradients of these ugly stripes Show.

Once high-frequency pulsed LEDs give her light, and a weaker light is achieved by longer dark periods between the pulses, you can only with a CCD recording good results or even by special LED video lights that do not have this behavior.
