In
microscopy, digital SLR cameras are the better video cameras!
Digital
single lens reflex (DSLR) cameras are the better video cameras thanks
to their HDMI
video output and “Live View” function.
Modern
DSLR cameras with HDMI output (High Definition Multimedia Interface)
and Live View function are ideally suited to presentations and
discussions using large HD monitors and projectors.
Old
analogue NTSC or PAL
video cameras only have a maximum resolution of 768 x 576 pixels.
With the aid of the digital HDMI output, a maximum resolution of 1920
x 1080 (FULL HD) is possible.
Using
large-area sensors (36 mm x 24 mm “full frame”) results in a much
better signal to noise ratio than is the case with the majority of
video cameras (CCD and CMOS), which generally only use small sensors.

A
far superior image
quality is achieved through the digital transfer. The
high data transfer rate (10.2 Gbit/s) of the HDMI 1.3 connection
permits colour depths and 30 to 48 bits for each pixel.
The
versatility of digital SLR cameras and the superior image quality at
very reasonable prices make them indispensable for many applications.
Large batch sizes result in an unbeatable price/performance ratio.
Unfortunately,
HDMI output is not yet the standard video output for all digital
cameras.
In
most cases, only analogue video output (TV out) is available.
However,
with the better DSLRs, HDMI output is available.
