From an old similar question (see http://www.mathworks.com/matlabcentral/newsreader/view_thread/83267), getframe is perhaps the most simple way to save a colorbased image by e.g.:

imID=imread('image.tif');
imagesc(imID);
axis image;
colormap('jet');
set(gca,'CLim',[0 255]); %Important!
im=getframe;
image(im.cdata);
imwrite(im.cdata,'nice_image.tif');

Note that you use the command (see "%Important" above)

set(gca,'CLim',[lower upper]);

to set your color limits (lower and upper respectively).

I just realized I might have misunderstood your question: is it the black/white image you want to have saved?

image in the comment is the image to be saved ... I used imwrite to save the image ... but the result was as in the question

Looks like it was somehow quantized before you saved it. Just don't do that.
