I have been playing with my camera board a few minutes and found that even if I try to set the -t option to low values and suppress preview output, the camera LED is on for about 4 seconds when taking a picture with raspistill. Is it possible to access the camera faster to take exactly one picture? Also, unfortunately the documentation on the RPi-Side is rather lacking, given they are producing and selling thousands of these things - can the camera LED be used to synchronize to the acquisition (e.g. flash)? I read that the "warning, camera is on" LED output can be suppressed and reactivated by IO, which leaves to the assumption that the LED is not controlled by the camera and thus triggering is not possible due to latency (unless this is fixed and comes on before acquisition). http://www.raspberrypi.org/camera https://github.com/raspberrypi/userland/blob/master/host_applications/linux/apps/raspicam/RaspiCamDocs.odt http://elinux.org/Rpi_Camera_Module Sensor: OmniVision OV5647 http://ovt.com/products/sensor.php?id=66
