How to get Data image from the camera?

Question

Arduino

I would like to interact with the camera in arduino.

What camera to use?

How to get a pixel array of rgba values ​​from the current frame of an arduino camera in real time?

Answer 1

Spoiler: The performance of a standard arduino (with the atmega328 gem) is not enough to get practically usable frames in real time.
This requires a powerful stone with DMA and a graphics accelerator.

Answer 2

In your favorite search engine, type "arduino camera" and see a bunch of links to the modules used, examples of work, finished projects.

Answer 3

Change arduino to esp8266 or esp32 - then the question will more or less make sense

Answer 4

A normal arduino can't work properly with a camera.
If the goal is in the name, look for one of the boards that supports programming in the arduino environment like esp32
