Videobild vs. Kamerabild

Video vs. Camera image



Frage von sanmyaku:
November 2005

I am researching names from the area of video technology for a thesis and "hang" just a little. Can someone explain to me the difference between the camera image and video image in the video monitoring?
1000dank



Antwort von baddimi:

I think both terms are so general as to allow them only from the specific context out a specific meaning can be assigned. Maybe you should post two sets of views, which contain these two concepts.

LG domain



Antwort von Nightfly!:

There is no clear definition or terms are used differently or as a synonym.

Camera image would be for me the DIRECT Picture of the camera (although it can direct the active picture, so what will be recorded straight of the camera, the OR of the internal camera captured Picture)

Video image would be for me therefore the INDIRECT IMAGE of the photographic material, the external of the camera is stored (possibly with another codec).

PS: Ask your supervisor or otherwise Prof times in the course.








Antwort von baddimi:

One possible definition would be synonymous. understood by the primary camera image picture on the sensor, according to the final reflective picture on the retina in the eye and the video image than on the monitor and recordable.



Antwort von sanmyaku:

Thanks for the quick answers!

A context would be for example the detection of motion in the video surveillance. Where the motion is detected, the video image or in the camera image?

A second context is the representation of the monitored scene on my screen. What I see on my PC in my display area. Are the camera images or video images?

;-) 1000dank



Antwort von Stefan:

I would assign live camera image = Image and video recorded image = Picture.

A motion detection especially makes sense in the live image. When detected movement, a VCR can be started up or be sold, a signal s.den guard.

On the PC (TV): you can check both. The Wachman is more likely to view the live image and the recording of detectives.

Good luck

I Agree! The "Live View" (directly active Picture =) camera image or the stream is analyzed for motion.

Antwort von sama:

Therefore brings together the distinction of image vs camera. Video not much. Strictly speaking, formed on the sensor of the camera initially a photograph. In the video technology that converts unlike the silver film into an analog electrical signal and then today by AD converter (Analod-to-digital converters usually) into a digital video image. This can be analyzed in terms of content through software, so changes to the Example of one frame to another. How does a motion detector, and yet it is not relevant whether the jump is so life or afterwards, even though only the first case appears to be useful.
