The
KP-D531 features an auto-change integration mode
for use in low light observation, at levels down
to 0 .02 lux. With auto-change integration, the
IR cut filter is removed and the camera is switched
to a monochrome mode to improve sensitivity. By
using a combination of CCD exposure time and field
memory, sensitivity is increased by 64 times compared
with a conventional single CCD camera. 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 noise reduction,
backlight compensation, automatic
sensitivity switching, auto change integration,
positive or negative output, and a 2H enhancer for
a sharp picture. Automatic color tracking can maintain
proper color balance with changing light levels
and color temperature. 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.
