connecting a ccd camera to a TFT LCD?

[almo]

Hi,

I bought 2 ccd cameras (PAL/NTSC) one color, and one b/w, and I bought
a 1.8 LCD from a different place. But they didn't come with data
sheets, and there's no markings to find out the mfg. They were from
surplus stores. Anyway, I've got a couple wires coming out of the ccd,
and a bunch of connectors going into the LCD, so I'm hoping somebody
can point me to a schematic on converting the signal from NTSC to the
LCD. I've found some info on NTSC, but nothing like a tutorial on the
electronics involved. I'm just trying to avoid re-inventing the wheel.
Hopefully somebody can give me some guidance. I've worked in image
processing for several years, but it was always military stuff and the
imagery came to me in a frame buffer, and I've lost contact with those
H/W people. But, for the moment, I just want to run the video straight
through to the LCD.

Thanks,
Alan

Parts numbers, type of lcd, photos could be useful..

I guess the CCD output regular composite video. And guess the LCD is an
TFT/STN variant where the LCD takes RGB data + Hsync + Vsync + PixelClock.
LCD also need power and then power to it's backlight. IF so then you need
sample the input video at high frequency. Seperate colours & sync.
Rescale output. And then feed this into the lcd.

Sorry bud but it sounds like that LCD only takes digital signal in.
Probably 3 or 4 bit of each color channels plus synch and power.
Trying to build a converter to change NTSC signal to LCD is a major
pain in the butt and not cheap.

Consider looking for used 4" PSOne LCD on eBay, it already takes
composite video in. Or for smaller LCD, look for pocket TV with
composite video in. Trust me is'a lot easier than trying to adopt an
unknown LCD display.
