Is video output from a camera possible?

Projects General Guidance
1

There are a range of boards that have a camera and an Arduino IDE option, such as Sparkfun Edge, and CoralMicro which either have HM01B0 camera or option.
The latter definitely can output video over USB.
What other boards might?
ie might Sparkfun Edge?
Are there others? in particular any supporting TensorFlow Lite.

coralmicro is QVGA 24bit colour (jpeg) 324*324 @25fps
however I did not find anyone has implemented this example using Arduino IDE as yet. Grayscale is just as much of interest hence Sparkfun Edge.

Depends what you mean by "video"

People have done basic PAL/NTSC composite on AVRs...

eg,

The Arduino Uno can produce low resolution black and white video. Use the TVout library.

PAL/NTSC not what I had in mind, tx

So what did you have in mind?

There is no evidence for "video over USB" in the module data sheet. If you ever manage to get it working, let us know.

Look a little harder, here are 2 projects:
This one:

is part of the initial setup:

This one is a little simpler:

there are others, but the ones that I found that use Arduino IDE are currently limited to single frames. Not clear to me why at this stage.

thanks!

If you consider sending image frames over USB to be "video", fine. You can do that over UART serial, too, just slower, using just about any MCU.

10

fine, did you have a link to any project with a camera and a comparable data rate?
if not...

In my experience frames are often preferable.

They have less or no data compression, and don't require expansion.
The Raspberry Pi was problematical for many years, as the data compression was high, and the raw pixel data wasn't available, meaning that for OpenGLES or other shader or tensor type applications, the quality was just rather poor.

thanks again
