Re: Bad color on 8MP camera output

Unfortunately there is no way to know what the AWB did in that particular scene easily. Few questions: 1) How long was preview running before the capture was taken? 2) If you run with "-st" in raspistill, does it improve the result? 3) If you take a picture with more of the grass in the FoV does it ...

Re: Pi Camera V2 raw bayer data

Direct comparison: http://www2.pic-upload.de/thumb/30656067/2016-05-15-RAW-vs-Processed.jpg A real good job in getting the colours right! But looking the RawTherapee picture, a few more details and a bit more sharpness should be possible to get. Looking at the lawn or the details of the fence mesh ...

Re: CamV2: raspistill stops working after some time ENOSPC

@Koepi, we are adding some more logging to the firmware to try and narrow down the cause of the failure. Will keep you posted and ask you to send some logs again soon.

Re: CamV2: raspistill stops working after some time ENOSPC

Hi James, probably not related to memory allocs, they were provided in another thread and nothing suspicious there. I suspect it might be an I2C issue during camera probe: 3980780.092: assert( open_camera_driver: camera open failed ) failed; ../../../../../middleware/camplus/cdi/cdi_camera.c::open_c...

Re: New 8MP Camera - Q&A thread

Let me correct any misconceptions; 4 colours refers to the 4 colours in the bayer pattern, i.e. R, Gr, B, Gb. It is standard practice in ISP pipelines to treat the two G pixels independently. It does not mean there is a W pixel. Press release is interesting http://www.sony.net/Products/SC-HP/new_pro...

Re: New 8MP Camera - Q&A thread

From http://www.sony.net/Products/SC-HP/IS/s ... index.html, IMX219 does not have an RGBW array filter. No mention of any conversion hardware in the datasheet either.

Re: New 8MP Camera - Q&A thread

All the colour processing is handled by the Broadcom chip, just like the v1 camera. I do not recall any functionality for RGBW->Bayer conversions on chip, do you have any source for this? Seem to remember on the V1 RPI said they used the Broadcom chip to do the colour processing not the camera chip?...

Re: New 8MP Camera - Q&A thread

24h later - Cam crashed again. sudo reboot left the Pi in an unusable state, needed to pull the plug (power supply). Calling raspistill again threw this error: mmal: mmal_vc_component_enable: failed to enable component: ENOSPC mmal: camera component couldn't be enabled mmal: main: Failed to create ...

Re: New 8MP Camera - Q&A thread

@jbeale, good suggestion. I would be interested to see those results as well. @Koepi, could you capture the jpeg with full resolution (3280x2464)? Looking at the image http://www.pic-upload.de/view-30501599/snapshot.jpg.html , I think I might look to tweak the sharpening tuning a bit if I get some t...

Re: New 8MP Camera - Q&A thread

Read it as "I personally haven't tried it, but that's what the driver advertises". Naush (also ex Broadcom and has done most of this driver and tuning) has said he has had 10second exposures, however that is possibly from a lower level test app than raspistill. It is listed as working as both a sti...
