For those of you that wanted to see one of my test setups, here is what my workbench looked like today:

http://expert.ics.purdue.edu/~pertierr/dsc00005.jpg

I did some more tests capturing 7-bit/blue sections of frames and recording DV output at the same time. I confirmed that the camera indeed will work perfectly as normal while the raw RGB output is being piped out. It definitely seems that the raw frames are 771 pixels wide and a bit taller than 480(486?) but not much taller. There is a lot of the CCD (horizontally)physically masked off...maybe the masking can be removed somehow for a wider image???

Tomorrow i should make a lot of progress, because I am hooking it all up to my desktop for continous capture(instead of sections of frames with the logic analyzer in the picture), and also, the big brown truck comes tomorrow with some parts that might solve the whole probing issue....looking good so far.

Cheers,
Juan

Rotating the CCD's

Juan-
Since you have first hand knowledge of the ins and outs of this camera's CCD's I have a question for you.

How hard would it be to physically rotate the CCDs 180 degrees and remount them?

This would be very helpful for the all the DVX100 people over at the Homemade Mini35 forums.

Thanks and sorry about the off subject question.

-B

It doesn't look hard at all. The CCD's are easily accessible, and seem to be glued on to the prism. The trick would simply be to find some way which they can be re-attached(or glued?) while allowing time to align them correctly....i think the alignment of the 3CCD's would be the critical part, i'm pretty sure it needs to be done with test equipment.

Continous capture works. I was able to capture continous frames for the blue A/D at 7-bits. The raw frame size is:
771x494

I might be off by a pixel. From what I see, a small part of this is cropped when put onto tape, and the rest is compressed to fit in 720x480.

The only part left is to set it up to capture all RGB signals at full precision, which I am working on right now.

If this is adaptable to an XL1s I have the money waiting ;)

(although i've been silent untill now, because i'm waiting to see what success Juan has with his setup before i jump in bugging about the possibility of porting it to an XL1)

This is totally portable to the XL1s...the only problem is that i haven't been able to get the service manual which i need...if anyone can get a service manual for the XL1/s, please let me know asap.

A quote from Don Palomaki:
Quote:
In the US service manuals can be ordered from Canon, cost is on the order of US$55. To get one you may have to pass a gatekeeper that may ask you to sign a warranty waiver for any damage or alignment problem caused by attempting to repair or work on your unit.

The manual for the XL1, which I've seen, is very technical, does not cover all internal components and circuits, just the major ones, and would be useless to anyone but a knowledgeable technician with a bench of test equipment and specialized tools. If the XL1s manual is like the manuals for the old L2 and A1 series, it may build on the content earlier manuals by reference to them rather than reprinting material that is not changed from the XL1. The lens has a separate service manual

In the USA, start at 800-828-4040. Follow the prompts for parts if there is one

Keep in mind that this is the XL1 manual, not the XL1S. There
doesn't seem to be a service manual for it.

Thanks Rob...

I contacted Canon directly a while back ago and they told me that they do not sell service manuals to the public, but i'll try and see if this can be ordered directly.

Can you elaborate on what you want it to do? I'm not very familiar with LANC but i beleive it's an interface to do remote controlling of common functions like focus, zoom, VTR, etc....i might be wrong.

I beleive the DVX already has a LANC port, what do you want it to do differently?
