    At present, I have a DGCAM DS 3661 6.6m with 4x digital zoom

    When i take pictures I never use the zoom as its digital and makes pics blurry

    Just used my Cam in dubai, i got home and alot of the pics r blurry.
    Before ive printed them. In the past my pics havent printed too good.

    What do u think is wrong?

    I have it on the highest quality setting.
    The pics come out at 2976x2232

    Im thinking of gettin a new camera has my mams camera of 2mp, seems to do them better, when printed. How can that be when mines 6.6mp??

    Never heard of your camera. Do you have a link to a review site or makers homepage?

    In a camera the lens is one of the most expensive components. If your camera is digital zoom only and not optical then it sounds like the lens is where they saved money. Does not matter how many pixels you have if they are not getting a clear sharp image to start with.

    Just guessing - it could be some other reason.

    Probably best just to cut your losses and get a new camera. There's lots of good 4 MP cameras available nowadays which will give excellent pictures for about £100-£150. The longer you leave it, the more pictures you will miss.

    Not much help, I know, but that's what I'd do.

    Thats my camera pottsy, good find

    why on earth does it say its 6.6m but then
    3.2

    What does interpolated mean? im presuming this is why my cams crap.

    Iguess all of this explains my poor quality pictures and why my mams 2mp makes loads better ones than mine.

    Looks like im gonna have 2 get another Cam. Definitely with optical zoom.
    Any advice on cams with good zooms, good pixels (4m+), shutter speeds etc i guess. Im not looking to spend £100's. But would compare depending on prices

    Interpolated means guessed :)

    Go back a page or 2 in this forum for threads where your suggestions question has already been asked (and answered)

    Sounds like a cheap and nasty camera to me. I'd stick with the bigger brands like canon, olympus, fuji, pentax .....etc

    It's like enlarging an image on a photocopier. It can only be as sharp as the original source material - so the images gets ropier the more you enlarge it. Basically to make the image bigger using interpolation the software takes the pixels and then guesses what would happeen to those pixels if you tried to enlarge it 3 times. But there is only the original data to work from and so it looks blurry and soft.

    A higher quality lens can capture more detail in the first place. In some cases you get 2 cameras that have the same Megapixel resolution but the one with the better lens will give sharper pictures. Basically digital zoom ain't worth a damn.

    To sum up, you will get the best (sharpest) picture from the camera by changing the settings to the 3mp (1600x1400 or something like that) mode.

    Try that out before splashing the cash, you may be surprised.

    Interpolation is not guessing, it is a mathematical algorithm. An example of simple linear interpolation would be if I had the sequence 1,3,5,7,9 then applied linear interpolation I would get 1,2,3,4,5,6,7,8,9. In other words I am using some sceme to derive a mid-value between two values I already know.

    The image interpolation schemes work in a similar way, only with more complex algorithms. The more detailed image you start with the more accurate the interpolated image will be, you cannot add detail with interpolation.

    Yes, but any computer image software worth its salt would have a more advanced algorithm. A decent algorithm will take minutes, not fractions of a second to run.

    There is no point taking photo's above the camera's max real res, just as there is no point in using a digital zoom. Unless you don't have a computer.

    Digital zoom is generally a bit of a joke but if its the only way to get closer then use it. I tested digital zoom on my Oly 5050 against cropping a picture without digital zoom and the digital zoom was better. There is less compression applied to the digital zoom shot so you end up with more detail.

    If you are shooting without jpeg compression then digital zoom will be the same quality as just cropping.

    2048x1536

    which is the best for me to use then,taking into consideration my quality problems? and what m pixel would it be closest to?

    Its simple maths to get Mega Pixels (Mega = million) from the numbers your posted...

    2048 times 1536 equals 3145728 = 3.145728 mega pixels.

    From what you have said so far about this camera I would suggest you put it down to experience, sell it on ebay and buy something with a brand name behind it.
