If you like fast zebras, it may be possible to get focus peaking with a similar method - with DIGIC registers.
We have 4 scenarios for focus peaking:
- movie recording: we can only use C0F14xxx (display device), since these registers do not affect recording.
- photo mode (1x) or movie mode standby: we can also use registers that adjust image sharpness.
- zoom mode (5x, 10x): same as photo mode, but some registers may be different.
- playback mode: C0F14xxx (display device) or any custom image processing algorithm (not real-time).
The method of using sharpness registers looks very promising, at least for photo mode, so here are my findings on this:
- c0f2116c controls picture style sharpness: 0 = none, ffff0000 = max. It affects most of the other sharpness controls, so set a positive sharpness in picture style menu or in this register.
- c0f0f280 looks like a high-pass filter, but amplifies noise a lot. c0f2135c does some noise reduction and can be used here.
- c0f23164 enhances edges from bright areas, and looks great for peaking as long as the image is exposed to the right. If this could be configured to enhance edges from midtones, it's probably what we are looking for.
- c0f0f29c (cartoon look) enhances most edges, but it's too strong and adds a lot of noise. Doesn't work in zoom mode.
- other registers that seem to enhance edges or alter sharpness: c0f0f17c, c0f23140, c0f2314c, c0f2313c, c0f23134, c0f23128, c0f23124, c0f2311c, c0f23118, c0f230bc.
You can already try these things with some older binaries, or by compiling digic poke yourself, see
