Taken (will some mod.) from
pys60 (the full name is python for series 60) 1.1.3
provide both camera and graphics display.
So, it is trivial to take photo and preview.
from appuifw import *
image = camera.take_photo(size= (160,120))
canvas.blit(image, target=(8, 12, 168, 132)) # center it
Here I use the small size (160x120) for preview.
When the real photo is taken I can use the full (defualt)
size of (640x480) on my 6600 phone.
