When trying to take a picture up close it is blury.

Try turning on your flash for fill light. Steady your camera when shooting pictures

IT CAN'T DUE TO THE PIXELS IN THE IMAGE, IF YOU BLOW UP ANY PICTURE MORE THAN IS NECESSARY YOU WILL GET A BLURRED PICTURE TRY A SMALLER SIZE THEN GRADUALLY GO UP

Try a head cleaning cartridge.

You need to put the camera into "macro" mode. Check your manual for instructions.

What's your definition of "close up"?
Sorry to say its a very cheap camera. It will not focus on anything under 3 feet. It's called a fixed focal camera. Anything beyond 3 feet should be fine.

for the close up photo u have to use micro or close lens set

try pushing it back in and after you do that turn it on and see if the pictures aare blury ....

change the resolution setting in setting. and also you can adjust diplay bright ness and contrast for bets view & pics .thsi will solve the problem. Thanks Sangita

It sounds like your lens's focus element is stuck. Given the events you describe it is possible that a grain of sand has worked its way into the focus motor's gearing and jammed it up. Normally the small motor moves the focus optic in and out to achieve proper focus, if its movement is limited or completely jammed you will experience blurry pictures. The camera will have to be disassembled and the sand cleaned out to restore normal function. There are repair providers you can find online who can work on your camera.
