please fell free to post pictures and stories here in this thread,

about the KX151 cam (also knows as KPC-S700)

Datasheet the C type

Datasheet the CH type (hires)

http://www.ktnc-usa.net/KT&C%20Products/PD...CH%20Series.pdf

I have tested the KPC-S700C (lo res NTSC)

and the KPC-S700CH (hires PAL)

My comments on those two

power supply arcording to spec 12V +/-10% = 10.8 to 13.2V

mine craps at 7.5V and works perfectly down to 8V stable.

12V input 108mA = 1.296W

10V input 121mA = 1.21W

8V input 143mA = 1.144W

So if you have an unregulated voltage from 8-13V you can use that,

I have no idea about the max voltage (I dont dare to find out my self)

Temperatures:

50C at 12V, 45C at 10V and 43C at 8V after a few hrs at my desk.

again arcording to spec that have a max of 45C opperating !!

so they actually need active cooling or indoor temperatures below 19C to be within spec.

Picture: not much difference to see between the hires and the lores type,

not on a 42" plasma screen directly connected via scart connector.

they both perform extreamly well indoors, even with low light.

here is a picture indoor with a digicam a really good one without flash,

this picture looks really much like how dark it actually was.

This picture show bright even in color picture of the KPC-S700CH, picture taken on my TV set since I did now have a portable video grapper,

I had exactly the same light in the room, as the picture above !

Nice Thomas! I guess the low lux works fairly well in the dark room. Will you post some pictures of this camera behaving in an outdoor environment? Pointing straight, at the ground and then up in the sky?

Kilran have done that on a new video recording yesterday,

it shows bad AGC and colors changing when AGC is changing,

and bad sun and clouds handling, he said he liked the KX131 more,

since it handle AGC better and sun better and so on,

he also said he likes the KX151 for its fine hi res.

please kilran post pictures, comments, links to video clip.

AGC what means?

then kx131 is better than kx151, right?

AGC stands for, Auto Gain Control.

About KX131 being better, it depends, what is important to you, AGC or resolution.

For me resolution is very important so, comparing the AGC between both cameras, in my opinion it's not too big, but resolution has a big difference.

In fact there are better cameras out there than Kx151, I prefer1/3 of ccd sensor instead 1/4.

Any way, usually portable video recorder dont allow more than 640x480 (video in)

and with a camera of 520 lines you lost 40 lines (well... you don't if you use a mini-dv)

Some people say that there is a limit of lines you can send thru airwaves, they said the limit is about 400 lines, any one know if that's true? how many lines is the limit?

--------------------------------------------------------------------

well for me is better to see good a "low" resolution video

than see "bad" an high resolution video :P

wich one you think is better than kx151 and as light-weight as kx131?

1080 lines will still look better than 520 lines at 680x480.

Exact.

HD video downconverted to SD is better than video shot directly in SD. A camera never will give all the format allows (a DV camcorder will give you ~480-520 lines even if the format is 720x576, while an HD one will give you ~900 with a 1920x1080 format). So in a way shooting in SD still needs upscaling while downconverted HD will make full use of the format.

I prefer1/3 of ccd sensor instead 1/4.

The KX151 actually has a 1/3'' sensor. Personally I prefer 1/4'' as it gives more interesting angles with the usual lenses. For example a 2.1mm gives a cool fisheye effect on 1/4'' with 120° diagonal, but can't be used with a 1/3'' because of vignetting (black corners).

Regarding my thoughts on the KPC-S700CH, yes the resolution is much higher which is ver nice, but color handling is bad. Firstly saturation is a bit too strong, and especially the white balance will change with the picture. It's VERY annoying IMO, when you're flying and the picture always changes from pretty cold colors to overly warm and saturated ones and back all the time.

I have some footage showing it here but it's pretty crappy, I had been recording some NTSC video before and forgot to change the recorder settings after that, so the bottom quarter of the image is cropped and one can't see the ground that much anymore.

have you tried this with Goggle?

We have the same camera and i Theater goggles and the color is off and too dark even in good sunlight

Thanks 3R

Other example here, especially between 2:05 and 2:20 approximately.
