playbook arrived :-)

first impression: nice design, quality material and setup was super easy. update to newest OS started installing right away. only I was missing the confirmation dialog to ask for the power supply. the installer page mentions it, but no confirmation needed.

time for gambling... :-)

c64 dithering

needs some gamma correction, I'd say...

configurable...

made the dithering configurable to no, 4x4 or 8x8 bayer ordered and available for the C64 modes as well... GUI looks just more cluttered again :-(

lil' smaller actually...

to be honest, the gameboy camera had only a smaller resolution of 128x112 pixels. will add a mode for that, here a preview of the lil' smaller format:

it's even more cute ... :-)

ok, happy now :-)

bayer 8x8

after adding the bayer 8x8 matrix, have to do something about the brightness...


but this comes even closer to the gameboy cam :-)

the gameboy mode...

used some spare minutes last evenings and managed to implement the gameboy (camera) version. first approach without dithering was nice but not close to the original gameboy camera's dithering. it appears that it used some sort of ordered dithering. thanks to wikipedia:
http://en.wikipedia.org/wiki/Ordered_dithering
and the matrix
CGFloat bayer4x4[4][4] =
{{0.01,0.09,0.03,0.11},
{0.13,0.05,0.15,0.07},
{0.04,0.12,0.02,0.10},
{0.16,0.08,0.14,0.06}};
it is coming closer now.
here the first approach without dithering:


and now with ordered (bayer) dithering:


gameboy rocks! :-)
