A couple of questions from today
Jonathan asked me a couple of very good questions today and I thought I would share my answers.
What is the difference between a linear CCD and a Array CCD?
- A linear CCD is used in scanners and consists of a row of CCDs that moves down the document.
- A CCD array is used in digital cameras and consists of a grid of CCDs as shown in this picture
Is it just CCDs that are used in digital cameras.
- Some cameras use cheaper CMOS sensors, these sensors are not as fast and do not produce the same quality as a CCD. Wikipedia has this to say.
What does WRL stand for
- This has taken a fair bit of research and the answer was on the blog the whole time… “World Description Language”. Personally I take the view of a lot of the websites WRL is the file suffix for VRML files and stands for WoRLd.
So with all this on the blog I updated the Multimedia Glossary, after all what else did I have to do.
