dead/stuck pixels

catman · Sep 12, 2003

I have an Olympus C3030Z and want to move up to the 300D. One problem I'm having with my Olympus is that there are some dead or stuck pixels. I see one stuck at green and one stuck at red. It shows up in every picture and bothers me. I called Olympus and there isn't a solution other than to send it in for repairs. However, they hinted that the newer cameras has the ability to turn off these stuck pixels.

I'm wondering if the 300D has something like that. I hate to spend so much money and have the sensor go bad. I haven't read anything about this capability so maybe someone can enlighten me.

Thanks. Huy

I hope not to many pixels are dead. The solution is to repair the picture in psp or P.S. or another program. With the clone brush you"ve fixed it in a minute. A new fotosensor is much more expensive.

Can anyone (with 10D CMOS experience) comment this? Does the CMOS sensor have the same dead-pixel problems as CCD?

my 10D does not, but any sensor can have it. They typically map those out at manufacturing line, but one can show up. If it shows up you need to send it to Canon service and have it mapped out.

I was hoping that the current solution these days is something we can do at home perhaps via our PCs. Sending it back to Canon or any manufacturers is kind of a pain in the butt and that doesn't even account for the $$ if out of warrantee.

You have to send it Canon to have it re-mapped.

The process requires some precise mathematical computations and you are liable to make mistakes without the expensive calibration tools.

Last time I checked they still do not sell "Do-it-yourself" brain surgery kit.

that doesn't even

No do it yourself brain surgery kits yet...but just wait!

Seriously, it is a shame Canon has not come up with an automatic way to do this. The E-10, E-20 and some of the other Olympus cams have the feature in the menu. You simply select "map out bad pixels", turn the camera off, and turn it back on again. In less than 30 seconds you are pixel free! All they do is map the adjacent "good" pixel over the bad pixels slot. You'd never notice!

every 4th time you return it they give you a new one.

I can't believe it's brain surgery. It's quite obvious at times to see when a pixel gets stuck at green or red. My eyes can tell me that without the need for precise mathematical computations.

If seems to be an all software solution and reversible. So, if a user messed up, they can always send it in. But I still believe they should let us try to fix it ourselves first. Aside from the money, I don't like my camera shipped and away from me.

Tried it successfully on my c3000. Can't help with the 300D, sorry ;-)
