The resolution should be the same. The picture quality is also determined by how well the camera copes with light and other factors such as being able to replicate true colours, so there is variation. Some will be better than others.
The higher the pixel count the better the quality the picture will be since there is more saturation of the actual picture. A lower pixel count will give less crisp pictures if you plan to print them out at larger sizes. A 4x6 picture should be ok with a middle of the road pixel count.
The content of the picture and the "Quality" level you are using affects how many pictures a memory card will hold. A 1 GB card in a 6 MP camera will hold something like 450 pictures on medium quality and 225 pictures on high quality.
All other things being equal, the minimum number of megapixels required is 4, and that will give good postcard-sized snapshots. Anything less is inferior.
Yes, that's fine. You won't get a perfect quality, but it's fine. And when you look for good cameras you shouldn't only look at the pixels. There are other things that may affect the picture quality as well. And also, too many pixels aren't good either. A 12 mega pixel camera has a better quality than a 14 mega pixel camera if the picture size is a normal size. You don't need more than 10 mega pixels unless you're going to print a huge wallpaper or something.
the 4 mega pixel 1gb camera would have more space but the 6 mega pixel camera takes a better picture
This model Toshiba television will have theater quality picture due to it's 720 pixel LCD screen. Toshiba is known for it's picture quality, as well.
The content of the picture and what "Quality" level you are using affects how many pictures a memory card will hold. A 2 GB card in a 7.2 MP camera will hold something like 800 pictures on medium quality and 400 pictures on high quality.
Sadly, Windows Movie Maker cannot do this. If you would like a clearer picture, I suggest a camera with Higher Resolutions or a higher Pixel number. Personally I would buy a Kodak Camera, but that's just me.
That depends on the camera model, picture quality settings, JPG or RAW, and what you are photographing. Rough estimate = 200-400 shots
Depending on what you use it for is one matter. A 10 million pixel (10 megapixiel)camera takes great quality photos. My 3.2 mega-pixel phone camera is great for taking photos with and viewing on the phone and sometimes even on a computer screen, but it is just not good enough for expanding the photo and printing, but on the other hand a 10 mega-pixel camera is great for taking picture's, expanding them and printing them. So yes, 10 million pixels are good.
A 3MP camera phone is a 3 Mega Pixel camera phone. It is the quality related to how the pictures come out, relevant to their size. The resolution is length and width.
In general, higher Megapixels (MPs) are better if the pixel size is not reduced. So the sensor size needs to increase proportionately with the number of MPs. Why? Because a reduced pixel will gather less light, hence will be more noisy (poor signal to noise ratio). That inevitably leads to poor dynamic range (range of captured brightness levels). Nevertheless as the technology of manufacturing and data processing improves, it is possible to cope with incremental reduction in pixel size while holding on to image quality. e.g. jump from 7 to 8MPs on same sensor area. In general higher pixel camera will facilitate larger print size (all else being equal). For lab quality 8"x10" print (at 300DPI), at least 7.2Megapixels will be required. In practical terms, the type of picture desired dictates the number of MPs required. For studio-quality A4-size portraits or close-ups, especially wedding photos, you need a high-pixel camera . At the other extreme, if you just want to take snapshots of friends at parties, then only a low-pixel camera is needed: 5MP would be sufficient.
