Frage von gesa:
more recently I have with my camcorder (about four years old), a white pixel in the display, which is recorded seemingly synonymous, at least he appears to imagine s.gleicher synonymous when I play recorded tapes with other cameras. it usually occurs after 10 to 15 min after recording commenced at synonymous and remains in stby mode. when I turn off the camera and again anmache, he's gone and not coming back.
schonmal someone had a similar problem? what's the problem? probably a thermal problem? it's pretty annoying when it is overlooked that the pixel "as is" ...

Hmm, I would expect for a 3CCD model actually more a colored pixel errors. or all three sensors angleicherStelle should really be concerned?
Any dust on the prism? But probably would be black, right?
Errors in the process electronics? - Is the error always s.der same place in the Picture?

yes, the error is always s.der same places, but not permanently ...

Hello Gesa,
a technical failure would not, of course, so beautiful. Let time rule out the possibility with the dust grain:
Clasp your camcorder s.den on television, so you, the picture on the screen and you can compare directly s.TV device. Now the camera moves so that they learn different lighting situations (with the light / light). Occurs while the disturbing point on? - If so, is visible on the front lens dirt?

... and time go into the digital zoom. When the dot is increased, it is a defective pixel on the (a) CCD.

hello together,
've got something new rausgekriegt:
I infer from dust slowly.
the point is always the same s.der stelle.
He is white, its color does not change. in digitized zoomed state can be seen very slight fluctuations.
occurs in stby and on the rec mode.
I'm completely out of the camera and then once again, is to minimize the point and not First of coming back. that's funny because ...
He will definitely turn to the record, if I have a band synonymous with playing other video camera he has seen and synonymous to the log on the computer. is not only a matter of opinion.
If I zoom in digital, it changes its minimum size. the alteration is almost invisible.
you can order what to do? You can fix this somehow?
cordial greetings,

Antwort von Kiara Borini:
I have about the process paths for 3-chip cameras have never made a serious thought, but the images from the three individual chips should be saved to go somewhere together, before she picks up the codec and the tape wurschtelt.
Does that mean that in the camera as a sort of video RAM, of which is read from the frame? At the 1 - CCD-camera can indeed count done directly from the chip, the abergeht synonymous with the 3-chip version? If there is a cache, then it could indeed, in the matrix Kapazitzätsprobleme have a location and then to a false pixels (FFF / white lead).
If it is the CCD, to me not quite so obvious, why the white pixel is wrong. Any other color would make sense to me reason, but I know?! In a 1-chip camera I see it more easily. Something has just caught a complete square Bayer, OK. But why should the same three chips s.genau the same place are damaged? You're sitting s.zudem s.völlig different places separated by several prisms.
Even with a targeted laser destroys fire (through the lens pointers point exactly) a pixel, the intensity of the beam should be in the colors green and blue and appear to lower the resulting error Fabig, right?
And got error larger than a pixel? Have you ever captured a frame and analyzes the bitmap?

Hello,
A few years ago I had such a problem synonymous with a Canon XM 1st Also a white dot, but was when zooming in the digital area, much bigger. MUs that could only be a defective pixels on a CCD. Luckily I was still under warranty and the camera was repaired in just one week of Canon. The TRV 900 is not a guarantee but probably have more. Either there is a way to touch up in post the point or you sell it on Ebay s.einen hobbyist. A repair s.den chips, I think, is worthwhile in any case for such an old device. ... and then still synonymous Sony! As you can ensure you buy something new for it.

But since the outbreak of Geizzeit has the "toys" portion of consumer camcorders increased dramatically. I've synonymous nor a TRV900, and if something should go something breaks, I would have it repaired in any case - synonymous if I could buy myself a new device for the price (s.end with 3x 1 / 6 "- CMOS!). something like the TRV900, there are now no longer what to show the relatively high synonymous Used prices on eBay. ;-)
According to all previous descriptions of the way, I bet on a defect in the DSP unit (DSP = Digital Signal Processing). This can be - positive terms - difficult to repair itself ...

Hello,
Just read through your problem.
I need 1-2 days maybe I could get out what.
For all cameras synonymous consumer (prosumer) Is there the possibility the error memory for pixels delete them. As it specifically in the TRV 900 proof, I will not (not) yet. But I once saw in the subject after.
See you soon

Hello,
now I've found something. But with you it will bring nothing.
Because you said. After some time, will then get a meadow on point.
The stored memory on which that information is. remembers das
And when dauerzustand is weggerechnet these pixels. Plain language "of the defective pixel is turned" This is only valid if an error Permanently applied voltage. With you it is ok s.anfang. Then no more. That is why this effect occurs.
The defective pixels would be if he would augeschaltet of anfangan (da) after power up.
