Connecting a digital camera to a computer via video output 

connecting a digital camera via video output with a computer

With this method the camera's video output is connected to the video input of a video card (cheapest solution: standard TV cards).
The analogue signal coming out of the digital camera's video output is digitized and can be shown on the computer monitor.
For simple watching on the monitor the hardware requirements are quite low (CPU from 200 MHz upwards). For hard disc recording in full quality it is recommendable to use a CPU from 1000 MHz upwards.

Nikon Coolpix: connecting camera with video cable

Open carefully the side coverage of the digital camera. Turn it aside and insert carefully the plug of the video cable into the socket next to the USB port.

Video cable for microscopy use

After connecting one end of the video cable with the digital camera, connect the other end with the computer. In our example a standard TV card was used. To connect the video cable with the composit input of the TV card, you need another adapter (normally supplied with the TV card).

WinTV software for watching microscope videos

Just switch your software (e.g. WinTV32®) to the video channel and watch your images on the monitor.

Methodic Properties:

All methods mentioned above use only a small part of the maximum capacity of the video chips. In the digital camera, the primary digital image information is being transformed into an analogue video signal (PAL or NTSC). Compared to the digital camera's photo mode, this results in a heavy loss of information, but moving sequences can be watched realtime in return. The image quality is sufficient for examination or control purposes.
