Re: Camera Interface Specs

Sorry, I posted before I had completed my thought. Right now, we are getting the performance we need with a 720 x 1280 CCD (approximately 1 Mega Pixel) and a 15:1 analog zoom lens. If I understand this correctly, I would need a 15 Mega Pixel CCD to get the same performance doing strictly digital zoo...

Re: Camera Interface Specs

Unfortunately, we are a very small start up company with a very limited development budget. After an extensive search, I’m finding most IC manufactures of H.264 encoders are as paranoid as Broadcom. If you don’t want to buy a gazillion chips, you can’t even get a data sheet. TI is the one exception ...

Re: Camera Interface Specs

I’m shocked!

Yet no one has replied. Shocked, to...

Re: Camera Interface Specs

For our application, the camera has to be very small, very light weight and have a remotely controllable analog / mechanical zoom lens. We also need both an SD composite video output and some type of HD video output. So far, the only camera modules that we have found that meet these requirements do ...

Re: Camera Interface Specs

Jamesh, We have tested the Sony FCB-ix11. This is only a SD camera (480i, composite video out) and got excellent results using the factory default settings for everything. We only used the VISCA to initiate a self calibration after power up and to control the zoom lens. We are moving up to a HD (720...

Re: Camera Interface Specs

Getting back to the "universal" video input concept, the Pi would not have to control the camera in this situation.

Re: Camera Interface Specs

Jamesh, Most of these camera modules have a separate serial data bidirectional port. They usually support both RS-232 Voltage levels and also logic levels. They tend to use the Sony Visca data format for controlling the camera and getting data and acknowledgements back from the camera. Sony Visca is...

Re: Camera Interface Specs

Jamesh, Above is another example of a need for a “universal” video input. The camera that you are developing and tuning for the Pi will work for many people in many applications. But it won’t work for all people in all applications as cjowers7 noted above. He has a need for a very close focus distan...

Re: Camera Interface Specs

Jamesh,

As this thread seems to have gone the way of “where is my camera!” people, could you reply to my suggestion of posting an article on your home page to see what kind of interest is generated for an HDMI input (or maybe high definition analog component, possibly more universal)?

Re: Camera Interface Specs

I meant the video INPUT takes a “back seat”. As I said earlier, you really did make the video output “universal” with both composite SD on an RCA jack and HDMI. So you can use “anything” from the dusty old black and white (with an inexpensive modulator) to the new “gazillion” inch HDTV. And you made...

Re: Camera Interface Specs

I agree finding the right firmware writer isn’t an easy job. But it isn’t impossible either. I had offered to do the hardware earlier in this thread. But without the firmware, it wouldn’t work. And even if I had the firmware expertise, without access to the documentation it wouldn’t be possible to w...

Plus, you have the added advantage that you already have your camera driver so that a firmware writer can look at it as a code example. There are employment agencies that specialize in technica...

Interesting post on your home page today, “Coffee!”

I wonder if Quentin Stafford-Fraser had to go through this much techno-politics to get a video input on his frame grabber back in 1991? I guess this is progress ;.)

Re: Camera Interface Specs

Hardware, an HDMI to CSI-2 converter adaptor board. Not too expensive.

Firmware, I have no idea. I would think that over time, you would make more and more options of the input video processor available through OpenMAX. To start off, simply going "through" the video input processor.
