Re: My Camera arrived today... what now?

I thought that wasn't working yet! Or is it just 720p30 silently pretending to be 720p60 (youtube converts everthing to 30fps, so no way to tell by looking at the posted video).

Re: Foundation Camera Board information

For IR work, completely untuned raw pixel data would be preferable (you'd be ignoring the bayer pattern entirely and treating each subpixel as a pixel).

Re: Camera Interface Specs

Broadcom (very busy at the moment and will NOT be interested in the project - no money in it) Opening up their SoCs to the DVR and video processor market has no money in it? Time to scrawl 'CLUE' on an inflatable squeaky mallet and go bob some Broadcom executives! £30k-£50k dev costs are easily wit...

Re: Supported Formats or modes?

we only have a specific mode for 1080p30. It's not a huge leap to provide other mode though, but probably not at launch due to time constraints.
I felt a great disturbance in the Force, as if millions of machine vision researchers cried out in terror and were suddenly silenced.

Re: Camera Interface Specs

It also takes a long time to get right. Camera modules are always a PITA, the documentation is never sufficient, and the tuning takes ages, unless its a camera module that has an internal ISP, which is passed through and bypasses the Videocore ISP. But the OV5647 does have an internal ISP. Or is it...

The only HDMI->CSI-2 bridge chip I can find is the Toshiba TC358743XBG. Would that be the one?

Re: Camera module! (And a picture of JamesH)

Seeing that the port that this camera will hook up to is capable of pushing a lot more data straight into the GPU than would be possible via USB, how feasible would HDMI capture be? I could only dream of a bunch of Raspberries processing each other output and overlaying graphics or applying effects...

Re: Camera Interface Specs

Component video input would be quite useful for making a standalone video processor. There are dedicated boxes for doing things like adding scanlines to video (to replicate the look of older consoles on non-CRT displays), scaling to correct aspect ratios, colour correction, etc that could all be don...

Re: Camera Interface Specs

We've done something similar with HDMI in - converted the HDMI to CSi-2.
Is this a "we've done it with some other board, so it's theoretically possible", or a "we have a HDMI-in driver in the works for the 'Pi"?

Re: Lenses

While it would require some fiddly soldering, is there any reason why you could not purchase a raw OV5647 sensor chip, and mount it in place of the module? Of course, you'd need to spec and assemble your own lens assembly, but would the camera board/GPU driver balk at talking to a sensor chip that i...

Re: Camera module! (And a picture of JamesH)

Disclaimer: I am not a camera engineer. Looking through the OV5647 datasheet, the closest thing I could find to EDOF is the LENC (Lens compensation) setting, which can be disabled by setting a bit in one of the ISP control registers (0x5000 bit[7]). I may simply be looking for the wrong thing in th...
