3511.0. "help with digitizing camera needed." by SHARE::DOYLE () Thu Feb 22 1990 14:11

	I'm posting this in a couple of area's, so if some parts of this 
      note seem inapropriate to the Topic I've posted to, please forgive.
	I have a Digiview Digitizer for my Amiga 500, and would like to be
      able to transfer a series of video frames to digital format for 
      animation.
	I also have a Sony B/W security camera (don't know the model # off
      hand).
	The process I'd follow is this.
	Hook the Sony to my VCR, then record the images I wanted to tape.
	Then run the VCR output to the digitizer and capture the frames,
	one after the other to achieve the animation I want.

	Problem #1: I bought the Sony camera at a flea market, and of course
		    I have no documentation...
		    Normaly, this wouldn't bother me but there are a number
		    of adjustments on the back, and I have don't know what
		    some of them are used for (adjustable with a screw-driver).
		     I've discovered that one control moves a inner tube
		   lens (reciever?) for fine adjustments of focus, by moving
		   it forwards and back along a track.
		     There are 3 others on the back that I can't really 
		   determine their purpose. 
		     It's missing the plate on the back, so there are no
	           identifying marks to speak of. But if these are standard
		   to Security Camera's perhaps someone could enlighten me.
	Problem #2: Although the camera can get good results taking still 
		    pictures (hooked straight into digitizer).
		    And the VCR can deliver adequate pictures (hooked straight
		    into the digitizer).
		    And the camera records well to the VCR, sort of...
		    When I record to the vcr with this camera, and play back
		    the tape, it looks good.
		    When I try to pause the picture to capture it with my 
		    digitizer, it scrambles... or for a better description-
		    leaves the picture warped looking with a large black wavy
		    line running through it. Tracking the VCR doesn't help
		    and the VCR pauses nicely with other tapes including the
		    ones shot with a rental cam-corder.
		     This leads me to believe that it is the camera's "SYNC"
		    that isn't matched up correctly.
   After reading some other notes relating to the same problem, these were
 resolved with a switch found inside the camera that allowed it to switch
 between internal and external sync.
   Mine doesn't have one....
    
	Questions- Is there a unit that I can place in line between the Sony
		   and the VCR to adjust the Sync ?
		   Does someone out there have a similar unit (I know the
		   model # would help.. I'll post it when I get a chance to
		   look at it), if so, would it be possible to get me a copy
		   of the schematics? 
		   I'm afraid the lens has a slight (burn-in?), when ever I
		   leave on an area for a length of time then move it, the old 
		   image will ghost the new one for a few seconds till it 
		   adjusts. Can I get this repaired, will it cost major $$$?
		    If a video-signal booster, will allow a better picture
		   for a VCR taping to VCR, will it increase the quality of
		   VCR to digitizer? How about Camera to VCR/Digitizer?
		    And finaly, is it possible that someone out there could
		   tell me what those adjustments on the back of the camera
		   are?

								Thanks

Ed,
		I've tried something similar with a top-of-the-line
		Sony Betamax, the problem of course is that the
		freeze frame function is NO WHERE near as good
		as a framegrabber.

		I've been able to improve it some by trying to
		get a frame without the 'scan bar' midway down
		the screen (using the jog/shuttle wheel) but the
		improvement is not like getting a good digitization
		with the camera and the Digiview moduel.

		The best bet is a framegrabber($$$), or if you can
		get a deck that uses DRAM in the freeze frame
		circuit the picture will be better.  Also if
		you want b/w you can set that up in the first
		menu of DIGIview (for me that seemed to add 
				   some improvement)

		On the burned in image, my site A/V guy suggested
		opening up the aperture and focusing on a white
		page, it will even out the vidcon tube in the
		camera. He did WARN that while this fixes it,
		its unwise to make a habit of it as it shortens
		the life of the camera.


						Hope that helps,

3511.2Can't afford the logical fix...SHARE::DOYLEFri Feb 23 1990 12:0929
     Well, my VCR is not a top of the line model and I really don't have the
  $$$ to invest in one, same goes for the framegrabber (although I'd love to
  have both and a camcorder to boot.... and more memory....and a hard drive..
  ..,etc...)
     What I do have is the sony b/w camera and a 4head recorder with a decent
  freeze frame. 
     As I stated in my original I believe the problem is in syncing the camera
  signal to the vcr.
     I remember in the early digiview notes, many noters who had sent away for
  the WV*** Camera had problems with their first images because the sync switch
  inside the camera, was factory-set the wrong way. I believe the symptoms they 
  described are much like mine except thier's happened during digitizing and
  mine occurs during recording.
   The VCR will freezeframe nicely on movies, it will also freeze frame the
  the home movies recorded with a camcorder.
   The only time I get the symptoms mentioned in .0 is when I use the Sony B/W
  to record.
   Unfortunately, there is no switch inside my camera (that I can find) to
  switch sync. 
   Hooked straight to the digitizer, it performs flawlessly.
 
   P.S. Thanks for the cure on burn in, I'll try it.
   
   P.S.S. Has anyone tried using signal-boosters or other vcr related enhancers
          in line with their camera to the digiview module?
	  If so, any interesting results?

3511.3Digi-View/digital camerasTOOK::KEEGANFri Feb 23 1990 19:1738
I know this isn't a solution to your problem, but I recently
had occasion to try out Canon's new XAP-Shot digital still
camera with Digi-View.  This camera records up to 40 (or 50?)
images on a microfloppy diskette. It is very compact and has
the feel of pocket size field glasses. A playback unit allows
the camera to connect to a TV or Digi-View thru a composite
signal with standard RCA plug cables.

I fed some images into Digi-View, using the SunRize color
splitter to separate the RGB, and I was very impressed with
the results.  The rock-solid freeze frame resulted in a nice
clean image.  The color saturation was very good, and the
resolution was satisfactory for non-critical work.

I own the recommended Panasonic 1410 b&w camera and an Olympus
8mm color camcorder.  Although the Panasonic yields better
resolution, I find that getting decent color saturation
through those lousy plastic color filters is very difficult,
unless the ambient lighting is plentiful.  The camcorder
produces a reasonable image on a live subject, but using the
freeze frame mode on a recorded tape is nowhere near as good.

So, basically, the XAP-shot gives you the freedom of shooting
your subject without having an umbilical connected to your 
Amiga, and teamed up with the color-splitter, filter-free
digitizing.

Unfortunately, the price of this baby is still too high for me.
	~ $700 (down from $900 when they first came out)

Oh, by the way, I learned the hard way that to get the best
results out of digitizing (especially with a color splitter),
you must use good, video quality, shielded cables.

3511.4My two CentsCGHUB::MILLER_CChuck - Don't Worry, be HOPpy!Wed Feb 28 1990 01:0721
    Just a follow up to Peter Keegan's comments on the Canon
    XAP-Shot...
    I recently picked up a new magazine called GRAF/x at
    System Eyes in Nashua NH.  It has a feature article on
    this floppy-based camera.  They also speak very highly about
    it.  By the way, the magazine notes the list price at $999.
    
    Here is a quote...
    "As this goes to press, Canon has just started advertising some
    'big-brother' Xap-Shot models with more features and even better
    video resolution - but at a higher price."
    
    Canon RC-250 is the model number, it is available in a bloack or
    white finish.  the $999 price includes one video floppy disk, battery
    pack, battery charger, AC Coupler, Pin Cable, Mini-Plug Pin Cable,
    Soft Case and wrist strap.
    
    This sounds like a great gadget as the prices begin to fall in line
    with reality.

3511.5Yeah, I'd like one of those myself!SHARE::DOYLEWed Feb 28 1990 11:0811
    I've been watching the "zapshot" since they first introduced it in an 
    article last year (I can't remember the Mag, or exact date).
     I was hoping it would end up in DAK or COMB so I could pick one up
    without having to take out a loan. :')
     I think they have a lower priced model than the one reviewed in Graph/x,
    I remember seeing a sale at Leachmere's actually offering one for
    ~$650.

    What would be REALLY neat is to get a drive and the required software
    to transfer the shots directly in the Amiga, otherwise, you would still
    need a frame grabber.
