Hi,

Just uploaded new file here: http://code.google.com/p/400d/downloads/list
New:
- Focus point Pattern mode light illumination
- Corrected bug: display off when exit menu or Picture viewer mode if enter Menu or Picture viewer while Pattern dialog on.

Edit: name of bin file now added release date. Please rename to AUTOEXEC.BIN after copy to CF card.

Hi thaibv.
Hi installed the chdk firmware on my 400D. It's all ok. But the filename of the images is changed in _MG_5000 (the old filename was IMG_5000).
Is this a modify of the new firmware?

Another question, can You explain this "Focus point Pattern mode light illumination "?
Thanks

Some how or another you changed from sRGB color space to adobeRGB color space. Just go into your settings and change it back to small rgb
cheers. . . .

Red and blue led blink when you double press focus button to notice you "Focus point pattern mode" on.

------ FYI -- ------
can change position of items in Canon default dialogs (ex: Iso dialog, Measure mode dialog) but
not success to add something to those default dialogs.

thaibv:
have you ever test your hack with usb connection?
i noticed your modification at line 235, line 283 and line 417 in entry.S
this maybe cause usb function failed (at lease on 350d)
try to do some "ADD" to get the right value 0x386d4000 and 0xc00000b8.

Hi, I'm starting having problems with hight ISO's iso's greater then 100. The images are getting Horizontal Lines in them. The Greater the ISO the more line and the image produced is reddish. What could cause this issue and how could i solve it?

Thanks

reset all camera settings and custom functions too.

does it happen at all Iso speed greater than 100?

tetu_024

Done It Already But Still Invain. what could causing this ? Thanks

thaibv

don't know why, too little information to guess a reason
pls try this:
format your cf and reboot your cam from default canon rom.
take some pic and post result

tetu_024

sure will do some sample shots this afternoon. formatted the cf and booted from the default rom. Issue still persits. When the issue first started was when i was using the default rom. Could it be a ccd failure?

thaibv

not sure that the CCD error

try change lens, clean the ccd surface, reflash rom

tetu_024

I Re flashed with the original 1.1.1 rom again problem still there and i changed 3 lens and problem still there. I never cleaned the CCD. Could you please guide me on how to clean it?

thaibv

pls google for how to clean CCD and upload an image so I can see yours problem

This is the Image

tetu_024

The Above was taken with ISO 200 one could notice horizontal lines passing through the image

thaibv

sound like you have a bad CCD, but very strange that ISO 100 is OK

To make sure that it is not caused by a bad CF card, Pls try this final test to make conclusion:

Remove CF card, Set "Custom Function 10" to 1, Set "Shoot without card" on, set "Review time" to hold and take some picture at low iso, low shutter speed, high iso, high shutter speed... Press Direct Print button same time with Zoom button to zoom image and find whether horizontal lines occurence or not.

tetu_024

So @ low ISO (ISO 100) image OK.
@ low shutter with ISO 100 image OK
@ high iso (ISO 1600) image turns into red with lines
@ high shutter speed with ISO 100 image OK.

It really strange because if the CCD is faulty then all images at any ISO are wrong i suppose.

I placed a raw file @ the following URL i don't know if it could help u diagnose the issue.

Could a large speaker magnet cause this issue?Like electro magnetic interference? Because now i recall that the camera bag was near a Sub Woofer. From there onwards the images started to get like that. Is there a way to degauss the cmos? or else discharge it totally ?

Thanks

I guess anything is possible, take out 'both' batteries and let the camera sit for about 20 minutes. See if that helps. If it doesn't it looks like your CMOS sensor is toast.
