Camera Sensor Questions - Raspberry Pi Forums
good day everyone,
first wanted huge raspifan, keep amazing work.
pinoir blowing mind wanted ir photography never wanted pay mod fees charge 'convert' camera.
question imaging chip used , possible, impossible, , community can , can't help.
learn more things mean , understand how chip works better. think camera great way teach lot of different technical , artistic things.
here question, there list of capabilities image sensor , implimented , might in future on wiki somewhere?
know additional capture modes enabled after original camera release(thank broadcom chaps , omnivision) - http://www.raspberrypi.org/new-camera-mode-released/
amazing motion method using h264 vectors(thanks gordon) - http://www.raspberrypi.org/vectors-from ... estimation
oh , before clog post anymore, wanted send huge jamesh hard work on camera.
here list of stuff omnivision site , guesses on them, starting own document , once data collected post or give post on wiki or internet in general.
sensor uses called 'rolling shutter' - http://en.m.wikipedia.org/wiki/rolling_shutter
omnivision ov5647
http://www.ovt.com/products/sensor.php?id=66
1.4 µm x 1.4 µm pixel omnibsi technology high performance (high sensitivity, low crosstalk, low noise)
optical size of 1/4"
automatic image control functions:(all implemented on pi - no manual controls)
- automatic exposure control (aec)
- automatic white balance (awb)
- automatic band filter (abf)
- automatic 50/60 hz luminance detection
- automatic black level calibration (ablc)
programmable controls for:
- frame rate - yes 1 120fps(smaller capture rez allows higher framerate - see above link details)
- aec/agc 16-zone size/position/weight control - think not sure how control
- mirror , flip - yes
- cropping - yes
- windowing - not sure is
- panning - not sure is
image quality controls:
- lens correction - not sure
- defective pixel canceling - not sure
support output formats:
- 8-/10-bit raw rgb data - yes, raw direct sensor data see https://github.com/illes/raspiraw way convert image raw dng
support video or snapshot operations - yes
support led , flash strobe mode - no, not sure if added later
support internal , external frame synchronization frame exposure mode - no, not sure if added later
support 2x2 binning better snr in low light conditions - think used when use night option not sure
post binning resampling filter minimize spatial/aliasing artifacts on 2x2 binned image - yes
support horizontal , vertical sub-sampling - not sure
standard serial sccb interface - not sure
digital video port (dvp) parallel output interface - don't know is
mipi interface (two lanes) - yes
32 bytes of embedded one-time programmable (otp) memory - don't know or if used
on-chip phase lock loop (pll) - don't know is
embedded 1.5v regulator core power - yes
programmable i/o drive capability, i/o tri-state configurability - don't know is
support black sun cancellation - don't know is
help.
