Here is a preliminary test with the NEW Kodak 2/3" CCD sensor cameras.

I used a cheap Pentax 2/3" Standard Definition TV lens in the test, hence the softness...besides it was wide open at f1.5

30 fps video grab with normal house lighting.

No Color Correction at all:

BTW, the grab is from a camera of our 3D HDTV system:

Here a couple more grabs, now I used a Fujinon 12.5mm l” C-mount Lens. (saved as BMP straight out from the recording software)

Wide open at f1.4, 1/30th 30 fps.

I resize the frames (from 1080p) to 720p in Photoshop without any color correction at all.

This time I had less light on the scene, just 3 small lights in a fan overhead, plus the 2 lights in the background. (all 13 watts Compact Fluorescents)

Last time I had an overhead kitchen light on, that consist in two 2 feet 40 watts Tube Fluorescent lights with a plastic diffuser.

I lowered the contrast in camera to be able to “gain” a little bit more exposure (but is not the same as real Gain per say...) :

With my Nikon D700, I had to use ISO 400 to have a similar exposure...

Sometime in the few days I will go out and record something (with my Macbook Pro).

Probably a LOT of snow or something....

Thanks,

CR.

I apologize because this project has been canceled due to the fact that we are going out of business.

Thanks,
