We are creating a projetct for our university.
Our goal is that the camera takes one Photo and the arduino process it and gets the RGB code of the pixels aroud the middle and show its values on the Display. - In other words a color picker.
I would like to know if you guys can give us some orientation, the university lended us the Arduino UNO and now we have 1 month to do that. The camera and display will arrive in 15 days. I HOPE! We have an SD shield too
But well, some of my questions are:
How do I access the RGB matrix inside an image stored in the MicroSD shield? Is there any library for that?
Does the Arduino´s Processor have the power to do That?
First thing to make sure is that you don't make things too hard for yourself by trying to work on JPEG images.
So, you need to find out what other image formats your camera supports, then you need to work on code to parse your chosen image format.

Thanks for you Answer.
My University bought this camera: Micro Camera with LED Lamp 420TVL. I have no idea if they made a good deal as this camera is not made specially for Arduino. Will I have problems using it?
You have no hope with that camera and an UNO, even with the right type of camera just capturing an image and transferring it to the SD card will take 10s of seconds.
It's your project so it's up to you to do the system design and the calculations in fact I think you have been setup by your instructors in order to teach you the importance of doing the System Design BEFORE you do anything else.
But here are a few thing to look at
How fast can the camera send data
How fast can the Uno accept the data
How is the data to be sent and in what format and why
Then you can look at the the websites and maybe find something
After that you can ask the same kind of questions about the SD card
And remember you have only 2K of SRAM to work with on the UNO
If all you need to produce is a colour-picker, a camera may not be the best choice anyway - there are colour sensors with illuminators available.
Almost certainly quicker, though you haven't mentioned any time constraints.
So why are you going to use Arduino?
What kind of course is this? Engineering, Comp Sci, ???

I´am using Arduino because i find it incredible and i aways wanted to know how to use it. The teacher lended us the Starter Kit that the university has and said to google some tutorials. I´am doing that since then.

Thank you have much. I didn´t know such think exists for arduino. I will search that now.
It´s just a prototype for our project, there is no time constraints.
