Camera and screen

>>1047792
Bumping for interest. I am trying to do something similar, but I don't know how to start.

I got some advice from a friend, he told me I should first should the camera, then see which Arduino interfaces with it. Then pick the one fitting the best for my needs (Input/output options, computing power)

You dont even need arduino for this.
Get a camera that outputs rca ( pretty much any board camera) and a screen that accepts rca

Warning: I've never done this particular thing....

There are "ov7670" CCD imagers on aliexpress for $5 that communicate over I2C. Presumably there is a library out there somewhere.

The thing I've read about "Arduino video" is tho that with a regular Arduino Uno, one single 640 x 480 raw image just about fills the entire Uno's memory up. So you have to put a SD card drive on it too, and use it like a scratch disk: you stream the image directly to a file on the SD card, and then down-sample that image to a second file on the SD card, and then display *that* 2nd image. You can't just do it in the Uno's memory, there's not enough room.
And it's slow. Like 1 frame per 2 seconds, is the "live video" speed.

There was another place on aliexpress making an "Arduino Mega camera" that had an FPGA on the back of the circuit board, that you could set up to automatically downsample the images in real-time. So this worked a lot faster, but then you got images that were like 100 x 100 or something. I can't find it at all on aliexpress now tho, all I can find is the ov7670 cameras, above.

Adafruit sells a "TTL Serial JPEG Camera with NTSC Video" for $40 that can do jpeg compression on the fly as small as 160 x 120, so it may be the Adafruit version of the same thing.
It is adafruit product # 397
