Frage von morrfa:
Hi All,
I need for my apprenticeship examination as a documentation written. For this work I need to know funtioniert like a camera.
The prism technology with the dichroic mirror and the 3CCD technology is known to me. I know how to digitize synonymous then the three colors R, G and B. But what I do not understand is what happens afterwards. I still do not understand how the digitized signal comes on tape. How does the process look like this? What exactly happened?
Can someone help me here?
Thanks

Hello,
na for such an important examination, I would rather get myself a reference book in a Biblothek / a book store.
A short version:
The Lens is the "eye" and catches the light for the camcorder. Which lenses are fitted, glass or plastics, or what compensation have the lenses is very important.
After that converts the CCD / CMOS sensor "The retina is" the light into digital signals, ie the light information is presented in digital form with the numbers 0 and 1st Depending on the prevailing light conditions, the sensor varies the amount of time needed for image sensing.
After that comes on it is previously mentioned a 3 CCD or 1 CCD - is Beyer filter sensor.
The data will be passed by the CCD / CMOS s.The signal electronics.
There, the microprocessor converts (eg at Canon de known DIG! C DV signal processor) and its electronic signal processing chips for the digital information. The technology of the microprocessor is responsible for the image quality. The color processing is of fundamental importance if the best results possible with intense color is desired. Also for the accurate processing of the gradation and detail, he is responsible.
Thus, the microprocessor and its signal processing chips to convert the CCD / CMOS digital information into a recognizable accurate picture, which in turn
then transferred to magnetic tape. The sound from the microphone is of course synonymous leaked, the processor controls the name that I do not know.
