CCD Camera FAQ
What is the lux rating of a camera and how is it measured?
The lux rating of a camera refers to the sensitivity of the camera, and is a
measure of the minimum illumination needed for a usable image. Several factors
determine the lux rating of a camera, including F-Stop, color temperature,
IRE level, and reflection ratio. The lower the lux number, the more sensitive the
camera is.
What does the F-Stop describe?
The F-Stop of a lense is the ratio of the aperture diameter to the focal length.
It describes the ammount of light that the lense will gather. The smaller the
number, the more light the lense will gather.
What does the color temperature describe?
Color temperature is a measure of the wavelength of the light. Natural daylight
is around 5,500 degrees Kelvin. The higher the color temperature, the more energy
is contained in the light, which affects the camera sensitivity.
What is the IRE level?
The IRE level measures the anolog signal strenght. It is measured on a scale from
0 to 100 IRE units, 0 no signal and 100 is full strength. The output strenght needs
to be around 30 IRE to see a meaningful picture.
What is the reflection ratio?
