in k750 this was cmd5B (0 = enabled, 1 = disabled) but this doesn't work on k800. it's hard to search proper command and value simply because of some commands which co-work with registers (this from my reg table at 4shared account). in this case good testing & searching procedures are priceless... and of course a lot of luck

OMG i just realized how poor is autofocus in K800. W800 can entirely kick his balls in every aspect of work

Can you explain that a little more?

i thought the k800 autofocus was a bit poor comparad to my k750i, also this was found in the k770

have a look at it, it's very odd some kind of half camdriver

@raiderski, have you managed to turn off the k800i's bilinear filter????

the Bilinear filter has got to go i researched it today
http://wiki.beyondunreal.com/wiki/Bilinear_Filtering
if you look at photos taken with the k800 Bilinear Filter on then look at pics taken with the k770i & t650 Bilinear Filter off, you can clearly the affect.

no i don't agree with you number1
from that pic showed in
k770 vs k810i thread it is obvious that sharpness is high.
bilinear filter is actually a low pass filter, and from that webpage you found you can see aliasing effect in "3x Scale Point filter" image and antialiasing effect(low pass filter) in "3x Scale Bilinear filter", and sharpness is actually high pass filter! low pass and high pass filter in the same time?!!
so i can conclude that that isn't bilinear effect on K800i.
and still i can't understand how bilinear filter will work when there is no resizing

Damn...the low pass filter interpretation of the interpolation is purely a mathematical point of view, our K800 is not doing fourier transforms. You can't think on interpolation only as a low pass filter, but as a low pass filtered spectrum of an expanded DFT. In practice, interpolation is a geometrical problem in what we calculate average distances/colours.

Ok, our K800 is not doing fourier transforms, but bilinear filtering is a low pass filter that works in spatial domain with the method called "convolution". it's actually a weighted matrix, sliding as a 'window' on the image(that can be considered as another matrix). on that webpage i provided you can see that weighted matrix(bilinear kernel).
