Question

stormforge
Customer

I need a color video camera (not camcorder) with a standard NTSC output which gives good performance in low-light situations and costs less than $2,000.  My basic requirements are:

1. Color video camera with standard NTSC output
2. Better than average sensitivity (low-light performance)
3. (less important) Good performance in high-temperature environments
4. (less important) Fast electronic shutter
5. (less important) Noise-reducing internal processor

It would be great to have a table (excel?) comparing a variety of cameras from a bunch of different manufacturers.  Would be nice if the table included a bunch of info about each camera such as sensor size, resolution, signal to noise ratio, etc...  Here is an example of an almost suitable camera:

http://rock2000.com/products/panasonic/live/panasonic_wvcp484.php

This camera is rated at 0.5 Lux in color mode.  This is not so good.

Background:
Color video cameras typically have poor light sensitivity (usually measured in Lux) compared to similar monochrome video cameras.  I'm hoping that some manufacturer has made a breakthrough that has improved this situation.  One option, which may be too expensive, is to cool the sensor.  This $6K Hitachi camera uses this approach:

Please email if you need more guidance.

Thanks!

Hi Bill,

I have been studying the specs of many cameras and the Hitachi KP-D590 seems to meet your needs.

Hitachi KP-D590 1/2" High Sensitivity DSP Color Camera
"The KP-D590 is a DSP camera designed for low light observation, at levels down to 0.001 lux. Ideal for use in fluorescence and darkfield imaging systems, the camera uses a combination of CCD exposure time and field memory, to improve sensitivity as compared with a conventional single CCD camera. A maximum integration time of 8 seconds is available, allowing use in extremely low light situations.
Thermoelectric cooling is used on the CCD to reduce the effects of dark current noise at long exposure times. Digital signal processing is employed, and enables new functions such as digital noise reduction, backlight compensation, automatic sensitivity switching, positive or negative output, and a 2H enhancer for a sharp picture. White balance modes include memory, auto tracking white, and manual, where the user can adjust red and blue gains. A four times electronic zoom with pan and tilt feature is standard, and allows magnification of the picture even when a standard lens is used."
 * Illumination range from 0.001 to 100,000 lux
 * Thermoelectric Cooling for the CCD
 * Digital Noise Reduction
 * AES, BLC, ATW, and AGC functions
 * RS-232 Remote Control for all Camera Functions
[see specs]
http://avsupply.com/details/kpd590.shtml

KP-D590 $1799.00
http://www.jknelectronics.biz/servlet/Detail?no=57

Please let me know what you think. As you know, there are many conventional low light cameras available for under $1000 but as I understand it, you require a better quality and so I haven't pursued them. So far, the KP-D590 is the only one which seems to meet all of your needs and hopefully it's just what you are looking for.

I'll look forward to your reply,
Patricia

Thanks Patricia -- that camera is on the mark.  It's good to see that there are less expensive cooled cameras.  Did you find any others?  I'm a little concerned about the "integrating" feature since that means that the camera improves its low-light performance by leaving the shutter open for a long time -- this means it's not useful for moving images when it's using this feature.  I found the datasheet, but it's not clear what the performance is with the integration turned off...

What were you finding with non-cooled cameras?  Are they all still up around 0.5 lux?  If so, can you put a little more time into producing a spreadsheet which compares only actively cooled cameras?  If there are some non-cooled cameras with 0.1 lux or better performance, I'd like to see them too.

Thanks!
-Bill

Hi Bill,

Good, I'm glad to hear that I understood your question and that I'm on the right track.

The IK-1000 Starlight Color Video Camera is another cooled type but I think you'll have to get in touch with them to find out the price (pricey I believe).

IK-1000
Starlight Color Video Camera
*.00025 lux minimum illumination - Reproduces full color, full motion images in starlight conditions
*50 dB signal-to-noise ratio - Provides industry-leading sharpness in all light conditions
*Electron Multiplying CCD (EMCCD) - Generates new electronics dramatically increasing sensitivity at very fast speeds without the common readout noise of traditional CCDs
*Adaptive recursive noise reduction - Reduces CCD output buffer noise in low light conditions
*Peltier cooled CCD - Maintains constant temperature of CCD to maximize low light performance
*Unlimited distance range
*Compact and maintenance free design

Are you in a hurry? Narrowing down the search to .1 lux or better will help but it will take time.    

Thanks,
Pat

Bill, it's disappointing to me that I've ended up with such a short list to show for all of my efforts and really there is only one that covers all of your original parameters (Hitachi KP-D590).  It's easy to find 0.1 lux b/w cameras but the moment you add color, they seem to mysteriously disappear as you will see if you try the advanced search on the OPSCI website.

Good luck with your camera hunt :)

Thank you.
Sincerely,
Pat
