Question about Pentax Optio S4 Digital Camera

Optio S4 Pixel problem

I got my S4 today and it has a wite spot on every picture in the same place. I guess that it is a dead pixel, or group of pixels on the sensor. Can I do anything about it? On my Olympus camera I can use a utility to map the bad pixel out. Can I do that with the Pentax?

That is a stuck pixel that never changes - always full on - and causes a clump of adjacent pixels to do the same. Exchange it if you can.

White spot on screen


Sounds like you are describing stuck/dead pixel.

There is no fix, it is a Pixel gone out in display panel, good chance it is just stuck and will right itself but sadly sometimes they dont and the only fix is to replace the entire display panel
Manufactures warrant such defects different depending on amount of dead pixels on screen is considered faulty, ie 3 pixels grouped or 5 separate ones .

Why the white or black spot on LCD Display


Dead and Stuck Pixels <br /> Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel. <br /> A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background. <br /> A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed. <br /> Hope this helps, if so do rate the Tip

Tiny black spot lcd


Erika, Do you mean you have a black spot on the LCD of your camera?
We call that a dead pixel. Can be black and can be white. Most LCD's sooner or later have a one or more dead pixel(s). As long as they are not in the centre of the screen you won't notice them. Even dead pixels on the camera sensor can happen. These you won't see at all, because the software does calculate what that pixel would look like in that specific shot. And the software will place a correct colour on that spot.
Try to live with the dead pixel(s). you won't see them on the actual pictures. Not on the computer to tablet and not on a print.

I have a Nikon coolpix 5700. Recently have taken a bunch of pictures that ended up having pink spots show up on the pictures. It does not matter what setting the camera is on or how the zoom is set it...


Your CCD sensor most likely has what is referred to as a "dead pixel" or "stuck pixel", which is a pixel in the sensor that is not functioning properly anymore. There is not much to do to get it fixed. If you have an image editing program such as photoshop, corel draw or gimp, it is very simple to clone or heal the pixel out.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Black spots on screen in the top corner and bottem of screen


how big are the black spots? are they pixel size? i have one black spot too but its called a "dead pixel" when ya buy laptops these days, sometimes...they will have a dead pixel gaurentee for like 25 dollars, but i didnt choose that so now im stuck with one annoying dead pixel on my 5 thousand dollar laptop but im fine with it i guess. when my screen gets bad, im rich enough to just replace the whole screen anyway. dead pixels cant be fixed i dont think just replaced by the whole screen.

Black spots appeared on 17" LCD Monitor-SyncMaster740N


you might have what you call "dead pixels" or a "stuck pixel" try a simple test like this one now it is not the most creative one, but it does help to see if that is the case. u might be able to Fix a STUCK pixel, but unfortunately you can not fix a "DEAD pixel" simply because it is DEAD.
try this website for simple fix instructions.
if is dead pixel what you have, if u can live with it, great, if not , it might be a good reason to get yourself an another monitor.

Good luck

DSC W1 dead pixel


If it has the remapping option, it doesn't say so in the manual. from what I understand, every camera comes already with "dead pixels" and its already remapped so that you won't easily notice it. with time, more pixels drop off and you need to remap it again. Now the thing is, the remapping just makes the dead pixel an average of its surounding pixels, and there are photo editing programs that do the same thing, have the remapping option. so basicaly what i'm saying is that if you're out of warranty dont be in a rush to get it fixed. cheers
