W and H

[udibit]

Hi,

I would like to know if I can change W and H (which are set to 128, 96)?
How does it actually works if my input video resolution is from a camera with much higher resolution?

Thanks.

The TVout library resolution only affects the resolution of the overlay. The resolution of the input signal is unaffected.

Thanks Michael for your fast replay.

I have 2 more questions:
1. Is there a documentation describing the used libraries?
2. Do u know how many frames are being processed per second? and why did you add the 2 frames delay at the end of the loop?

Best regards.

The TVout library documentation is here:
https://code.google.com/archive/p/arduino-tvout/

But it’s not very useful. You can see the API drawing primitives by looking at the header file TVout.h. It’s simple to use.

The enhancements for the Video Experimenter are documented on the product page:
http://nootropicdesign.com/ve/

It can only do about 5-10 frames per second. I’m not sure which program you are referring to when you ask about the delay. There are many example programs for the VE. The Overlay example has a delay to give you time to actually see the output before erasing it again to capture a new frame.

Hi Michael,

I also measured it, and it took 140ms for each loop in the image processing example.
I need much higher frame rate, therefore I thought of using ARDUINO zero, the problem is that it has 3.3v pins logic.
from your experience will the ‘video experimenter’ board will work from 3.3v? analog pin?

Do you have other suggestion for compatible enhanced board which will work with ‘video experimenter’?

Thanks a lot for your support – Udi.

The Video Experimenter will not work with any Arduino that does not have an ATmega328 chip. It only works on Uno or Duemilanove.

I was able to get it to work on the Seeeduino Mega: http://nootropicdesign.com/projectlab/2011/07/13/ve-on-the-seeeduino-mega/
