Lens positioning, blurriness - Toshiba 57H81 57" Rear Projection Television

Step 1:
A webcam is first and foremost a camera that uses a lens to gather light reflected by an object. There are a number of reasons why the image captured by the webcam can be blurry, all of which can be remedied. Supplies from a photography store or hobby shop, along with items that most people already have in their homes, are needed. The webcam does not need to be disassembled in any way in order to obtain a sharp and clear image.

Launch the webcam's video program by selecting it from the "Start," and the "All Applications" menu. Aim the webcam towards you so that you can see the blurry image presented in the program's video window. Rotate the knurled focus ring that surrounds the lens at the front of the webcam until the image is sharp; if there is no focus ring, position the webcam closer or farther from you until the video image is sharp. Blow off the lens at the front of the webcam with compressed air. Moisten the end of a cotton swab in photo lens cleaning solution. Wipe the lens with the moistened end of the swab, beginning at the center and rotating in a circle until you reach the outer edge. Wipe the lens dry with a lens tissue in the same manner as was just done, to remove the contaminants that caused the blurry image. Launch the webcam video program that is on the hard drive. Select the "Advanced" or "Options" tab at the top of the program's main window -- depending on how the program is set up to bring up a settings window. Reset the "Sharpness" control to 65 percent of the total possible, using a slider control or entering "65" in a text field. Click the "Apply" button at the bottom of the window, followed by the "OK" button to sharpen the image transmitted by the webcam.

You did not say which lens or lenses you are using, but most auto-focus lenses have a switch for selecting manual or auto-focus. First, check your camera's menu settings to make sure auto-focus is enabled and then your lens to make sure you did not accidently leave it in the manual focus position? If it is in the auto-focus position and still not taking sharp pictures, switch it to manual and see if you can get it to focus correctly. It is also possible that your auto-focus alignment is out because your camera was bumped, jolted or dropped. If realignment is necessary, you can send the camera and lens to Nikon for repair or find a knowledgeable camera repairman.

No picture or one that is all blurry? If blurry,
Clean the lens and make sure it is not loose or damaged. The camera cannot produce blurry pictures at distances greater than around 0.3m ish as it has a fixed focus lens. If it really is blurred either you are too close to the lens, the lens to sensor distance is wrong (mechanical damage) or the lens is dirty.
I hope that helps

Most likely your fisheye lens attachment is out of alignment. An internal element may have come unscrewed or unglued. The other option (I'm assuming you have already checked this) is that it is incorrectly attached to the camera - check your threads and make sure it wasn't cross threaded and that there are no blockages to the lens attachment being screwed in completely. If the fisheye lens is not in the correct position relative to the CoolPix lens, then the pictures will be blurry.

Try cleaning the lens gently with a lens cloth or maybe a damp paper towel? Other than that - you may have something stuck in your lens that is making everything blurry when you zooom in...or the lens may need to be replaced to be fully functional. Do you notice any blurry spots when you zoom out that get bigger when you zoom in? If so something may be stuck in your lens. Good luck!

If your images are blurry and the lens wont move smoothly it is very probable that some kind of force on the lens has damaged a gear, barrel or even dislodged an element internally. When the lens detects an obstruction in its movement the camera reports accordingly,"lens error". You should have the camera checked by a service centre, it will most likely need the lens replaced as they are not serviceable.

Lens motor or lens servo amp is not working properly. Factory service is require. They will replace the circuit boards and or assemblies as required.

Just returned from trip to Cuba..most photos taken outside and few inside...all photos were exc. or good except the ones I used with the telephoto feature. Had I left it on the W feature,these photos would have been ok...also make sure the focus ring lens adj. is not on the macro imaging feature..found that focus ring lens setting sometimes moved when I put the camera into its case
Pancho-poppa..

I did the same thing to my Photosmart E327 and upon inspection, I found that the len had fallen out. I could not find it so I am trying to find how to get it replaced. The blurry picture began for me after the drop. Suggest that you check to see if your len has become dislodged, or fallen out as mine did.

Make sure the lens is clean. Soft spectacle cloth nothing harsh Check the you have not got it set to Macro. Make sure you are not holding the camera in such a way that the focus window is obscured by your finger, If all that checks out HP technical Support for further advice.
