Rendering and updating a colormap

I'm developing a library related to real-time image generation. To test it, I'm trying to make an app that can convert a

Color[,]

Color[,]

into an image and display it, updating at 60 fps (Color is a class with 3 float fields).
Ideally, I'd want my code to be like this:

DynamicImage dynImg = new DynamicImage();
every 1/60 seconds do{
  Color[,] colormap = dynImg.getImgAtTime(time);
  imageDisplay.setImage(colormap.convertToImage());
}

DynamicImage dynImg = new DynamicImage();
every 1/60 seconds do{
  Color[,] colormap = dynImg.getImgAtTime(time);
  imageDisplay.setImage(colormap.convertToImage());
}

where imageDisplay would probably be a PictureBox in a WPF app (with which I have no experience at all).
(This is of course pseudocode)
Any help is greatly appreciated.
