Hi Everybody
I am having a pop at porting this to firmware version 102B, using 100D as a reference
I highly recommend that you look at some other ports with the same dryos version. SX30 and G12 should be good examples. The existing ixus1000 port has many problems.
Don't forget what the H stands for.

Thanks for the advice reyalp, I have at least got it to the same level as the 100D version now (I hope so anyway!) - Ive never used CHDK before completing this port so I have a lot to learn now! I am going to play with it and see what works well and doesn't.

So far tried running a few intervalometer scripts, iso/aperture overrides and using the on screen zebra/histrogram modes have worked well, my biggest frustration with this camera was there was no manual control of ISO in a long exposure shot this has fixed this for me at least!

I haven't got any access to contrib changes back to the trunk (perhaps thats a good thing if my reference has a lot of issues) but ill post some links to the sources and bins in case anybody needs them.

See that post. in later posts you find image

http://chdk.setepontos.com/index.php?topic=5722.msg58881#msg58881

later i find out it is a

#define cam_CFAPattern 0x01020001 // Green  red  blue  Green

pattern i do testcode that show me number of 1 bayer pattern row and heigt (2*2) on display.I hold kamera on some red or green or  blue areas and see which number is the highest.so i see which pixel is sensitiv to the color.

but no other camera seem have this pattern.
the pattern of the IX1000 can reach with known patterns in chdk when, shift 1 pixel.but because every pixel need 12 bit i guess it do not work.

with this  0x01020001 images look correct, only in dark places its more blue than black.In bright places white balance is correct.

but because there is no dng4cr here that support this pixel format, no color matrix can calc and i try some color matrix settings and choose the best.

The Ixus 300 have same sensor, but the settings of Ixus 300 do complete wrong colors with Ixus 1000

FYI: With this changeset, philmoz has implemented support for DNG on this camera. Bug / success reports are welcome :)

thanks, i test the release 1.0 source and the pattern is correct now

Here i have attach a testimage and you can see in white areas red green and blue are ok, but in dark (right down quarter) red is 27, green is 2, and blue is 19 in the RAW.
here is a very huge color diffrence.
jpg is ok and red green and blue is 5

How can the color matrix modify that this is correct ?.

in imageprocessing i need lower green contrast and raise a little the red contrast to get good results.but maybe it can done in color matrix too

because of the diffrent pattern i can not use dng2ps

The autoISO work with newest 1.0 files too stable now and i use now overexp compensate.I see no diffrence.but i test more

#define USE_REAL_AUTOISO                1
#define OVEREXP_COMPENSATE_OVERALL      1

Can somebody please add this 2 defines to chdk camera source of this camera ?

this defines work too,

  #undef  CAM_CAN_SD_OVER_NOT_IN_MF
    #define CAM_USE_ZOOM_FOR_MF             1
    #define CAM_CAN_SD_OVER_IN_AF_LOCK      1

but i am not sure if this is save to any focus overwrite value.
Or have all Canon same values for focus near and focus infinity, so no camera special limit values are need ?

If so, then this can add to camera.h too

Hi everybody, been taking loads of pics on my 102B firmware. It seems to be bug free even takes good DNG's with Bernd R's change in Reply #343. I was hoping that somebody could commit it to the svn, I can check out but cant seem to commit.

CHDK has been totally awesome for astrophotography really enjoying it :) my only niggles so far are turning screen off in scripts does not work (have to plug in video cable to keep screen off) and I cant fathom manual focus and preview for afocal projection yet, thus far though so good!

Hello, I want to ask if someone can help me with finding firmware for photo camera Canon ixus 1000hs.? I have a problem with the camera as a photograph of iso3200 and ask to shoot iso3200 camera straight off, not even removable lens. Otherwise it works perfectly. So I think that is a problem with something firmware camera. So I decided to update the camera but no new firmware in official website. If anyone can help me please write to me by email: fx.tunay@gmail.com

Thanks in advance.
