GnF that looks like the difference between canons "Market ISO" and "real ISO"

Damn that is so true. Why does canon reports completly different iso?

Because Canon havnt high end firmware like CHDK^^ Also because it isnt a Camera for Professional use, so canon think its enough to show the "wrong" value

hello, why optical zoom does not work on video with last chdk? thanks

semi-automatic AF after zoom sounds OK, if you can find a reasonable way to do it. Add it to the bug tracker and submit a patch.

BTW, I have such patch for old (Allbest?) CHDK version. If anyone interested, I will upload it tomorrow.

well, who wouldnt want such a patch? probably in a new thread though, so it doesnt get lost 😀

I've the on/off problem again with sx110is-100b-0.9.8-755-full.zip too.
I hold the on/off button, the lens comes out, but the camera turn itself off with lens out...
Sometimes it seems all right. I try to find where it comes from.

The first beta versions didn't do that.

Live histogram in "always" mode shows only "noise", but with half pressed shutter and in "shoot" mode it's ok.
I know zebra is not supported yet, but it turns itself on sometimes.

I'm using the first beta's cfg file. Shall I delete it and setup everything again??

I'm thinking about beer. Would be nice. What are you thinking about ? 😉

😉 Yep. Where?

Hmmm, have to think about...

Turning on the AF lamp might be nice, but I'd be slightly concerned that LED is being over driven and is only designed to be on for short periods. It's also not really bright enough to help very much, at least not on any powershot I've used.

I'm afraid you are right.

@PhyrePhoX: do we need a new category like d3enc_v2 or am I wrong?

It uses the D4 values.

edit:
I've merged chdkj's patch, set the (hopefully) correct FI2 options, the blacklevel and done a couple other minor cleanups. SVN rev 755.

Thank you indeed!!!

Are your sure that core/gui.c in SVN 755 is clean? First line looks strange.

Strange. I dont have any clue... Please try to narrow it down. Did you check your camera firmware version? Is your SD card free of errors (filesystem check or physical write test)?

really strange i dont have problems like that after the soundfix.

I'm not sure what you mean ? gui.c didn't change in 755

The first line of the file looks normal to me gvim, windows

zodiac757

i've moved the old chdk config and started to reconfig - maybe it was
since then no error

Code is correct , sorry. Mixed something up on my own installation with diffs.

Autobuild is working again...

4) Has anyone managed to make any of the motion detection scripts work on the SX110IS?

Nope ??? I tried everything I found from wiki but couldn't get them to work properly.. The "Multipurpose Motion Detection" runs but seems to detect motion everywhere, no matter how I try to calibrate it. 🙁

same here...

@axu89
Try fudgey's Fast MD script...

just tried.. same problem

Greetings

I tried it too, works like the Multipurpose MD. If I turn threshold up to >100 it wont trigger by itself nor with motion. I also tried tuning the other parameters like with the other scripts but no, it wont work like it should. 🙁

Didn't play with scripts so far but did you try do mask some cells? There are hints about at the sx1-thread (https://chdk.setepontos.com/d/3410/211).

I tried. But if you try running the script, you will notice that masking the border cells is useless since motion is detected everywhere "randomly". Its strange..? ??? Maybe Im doing something terribly wrong? 😛

Just an update:
Still some issues left (http://chdk.wikia.com/wiki/SX110IS#Known bugs.
- Scripts (at least Motion Detection Scripts) are not working as expected --> ?.
- Zebra draws dots over whole LCD screen (and from time to time even the expected zebra patterns -blink 2 or 3 times-) already with low sensitivity for both over and under exposured areas (the more sensitivity the more dots will be drawn) --> No clue.
- GetBatteryTemperature crashes the cam: hmm, what do to? Do we have really an originally broken function here?
- Auto-ISO-Shift doesn't work (https://chdk.setepontos.com/d/2838/235) -->I'm really unsure about this. It seems to me that Auto-ISO-Shift works as expected: ISO selecting by camera will controlled by user settings.
- ColorMatrix (for RAW/DNG) is still unsolved.

I've checked all camera dependent code and now I'm running out of ideas.

Ok, thanks for testing. Don't think that you are doing something wrong regarding MD-scripts 😉. Can't exclude that some other things are broken in SX110-port and you are trapping in a subsequent error.

PhyrePhoX

perhaps ewavr or fudgey can take a look at the getbattery stuff in the dumps. if they cant find the function, nobody can 😉

hmm... why are you unsure about this...
here is what i do (an example):

(auto-iso-shift must be enabled in the canon-options and alt-key must be the print-button)

I am sitting in a dark room. Boot the cam WITHOUT CHDK. P-Mode. Iso is manually set to 80.
I am holding the shutter half-pressed. it shows:
ISO 80 ; exposure 1/5
The print button glows blue. I press it. Now the settings changed to recommended auto-settings
ISO 320^ ; exposure 1/20

now i boot the cam WITH CHDK. (same room. same settings)
I am holding the shutter half-pressed. it shows:
ISO 80 ; exposure 1/5
The print button glows blue. I press it. and nothing changes. neither with a short press nor a long press.

what are you doing (or rather why does it work as expected with your cam)?

greetings
