The image that i took is not so clear like before , and it is bright very light when i take picture under sun light .

Not clear when you have white lines. While looking on the screen or really on a image.
Lots of camera's produce lines on the LCD, when using the LCD to frame the picture. Special when there are small and sharp lights in the image. But the sensor is not capturing that while making the picture. It is a sort of smear on the screen.
Also, when you try to make a picture in bright lights, you can get flares, but those you can see on the screen and in the picture. To fight flares, most camera's and lenses come with sun hoods. Your camera does not have a hood, so try to avoid shining bright lights on the front of the lens.

The whole point of a webcam is to be able to see the person you are speaking with, and let them see you. When the image broadcasted by your camera is too dark, the person on the viewing end won't see anything but shadows and dark shapes. Learn how to brighten your webcam image so the people you chat with can see you.

Place lamps behind and to the side of the webcam. This casts a light on your face, but the lamps will not wash out the image because they are behind the camera. Turn off lamps that are behind you. You have trouble seeing things when you are looking in the direction of the sun or a light bulb. Your webcam has the same problems. Don't make it stare at a bright light. Open up a white screen on your computer to brighten your face. The white screen will create the brightest possible light from you computer screen and help lighten your webcam image. This option is best when lamps are not available. Open up an empty tab in your Internet browser, or a blank Notepad document, and expand it to the full of your screen. Adjust your webcam settings. The settings available to you will depend on your webcam, but many of them offer a "Brightness" setting that you can increase to lighten your webcam. Open the program that came with your webcam, then look for a "Settings" or "Options" menu. Increase the "Brightness" setting until it has lightened your webcam enough.

Hi, Don't put screen in direct sun light or bright light. Bright lights will destroy LCD screen. The LCD screen has some adjustments on back. You might be able to readjust picture brightness.
Good luck.

This problem may occur if camera got too much bright inside the lens. Try to turn off the flash light and try to avoid taking picture in front of direct light, sun or lamp.

Please RATE.

If the sun was reflecting off the water, it fooled your camera into thinking there was so much light, it had to decrease the exposure. You could have used "exposure compensation" to get a better picture.

its sound like if the iris motor wont go to the good position its could be the light sensor thats needs to be tested...
?

hope that give you an idea

They are normal.

using the blue Fn key(usually on bottom left to side of space bar)..look at Funtion keys on top, under the screen. One of them(F5 or F8) will have a blue sun image or a monitor image to increase or decrease the brightness. press the Fn key first, then the one that increases brightness until it's good .

change the lcd setting by pressing menu then right arrow. go down to the sun picture and then click the left arrow and put it in the middle. i hope this helps.

This is a common problem with all LCD screens without anti-reflective coatings.This is normal. Increase the brightness of LCD while shooting in the sun. Internal memory normally takes only a few images. This is normal. Use a memory card to shoot more images.
