which arduino do i need

i am very new to arduino or electricity and i am doing my first project but i am not sure which arduino do i need. i dont have a lot of money and do want to make an expensive, stupid mistake.
in connect to the arduino an oled 0.96" blue screen, a camera like this, an arduino Bluetooth like this.
and the arduino is connected by the end to a phone via Bluetooth.
thanks

What do you want the Arduino to do? Why do you think an Arduino is the right choice?

thy are going to be smart glasses that get the image from the camera, then run a program i made than return the output to the screen. the program is not too big its just that there is a lot of data but not to much around 1 to 5 megabyte(i dont have a good approximation now).
there would be another arduino connect via Bluetooth to the other arduino/phone which sands a signal when a button is pressed.
i dont want to say exactly what the thing is. even though its not like i am selling this, its still a good idea.
i think that arduino is good for this project is because i did resource and its seems like arduino is the must handy for my purpose.

An Arduino is too slow and has too little memory to process images - even still images.

I suspect you need something like a RaspberryPi for your project.

You need to get some real numbers to work with. How many pixels wide? How many pixels high? How much data per pixel? That will give you a quantity of data.

Then, you can look at the interface between the camera and the Arduino, to see how long it takes to transfer a frame of data from the camera to the Arduino.

Then, look at how long it will take to transfer that frame of data over the bluetooth link to the phone AND to transfer the modified frame back.

Then, look at how long it will take to transfer the modified frame to the OLED screen.

I think that you'll find that a frame a minute is unachievable. Forget anything like 30 frames a second for decent videos on youtube.

Teensys are small, and much faster, but the bottlenecks are still going to be the serial connection to the bluetooth device and the slow draw speed on the OLED.
