Are megapixels diff. in diff. digi- camera brands?

Question

For example, pretend there's a Sony digital camera, that has 10 megapixels. And A Casio, Canon, etc., that has 10 megapixels, also. Do they all have 10 megapixels and have the exact same good quality, or are there some slight or big differences? I hope I'm not being too confusing.

Thanks :)!

Answer 1

They all have approximately 10 megapixels, but the cameras may have very different features and may produce very different pictures. The lenses or optics can make a huge difference, the processing that goes on within the camera, (converting to a jpeg, compression ratios, the ability to handle low light situations, focus, etc), and lots of other things. All cameras are not created equal.

Answer 2

For the most part, megapixels are just megapixels regardless of manufacturer- Kodak, Canon, Nikon, Olympus etc. The reason that Nikon & Canon DSLRs yield better pictures isn't because of the difference in the electronics, but the superior quality of their lenses!

That said, there are a couple of notable exceptions in the megapixel game: Fuji and Foveon.

Fuji handles pixels differently by arranging them in a honeycomb pattern instead of a conventional grid, which they call a SuperCCD. The end result is that a 6 megapixel Fuji S2 creates images of 9 megapixel quality.

Also when Fuji introduced their S3 Pro camera, they decided to dedicate some megapixels to the specific purpose of recording shadow detail which conventional sensors might miss, instead of simply increasing the resolution, which resulted in improved dynamic range. So their 12 megapixel camera is essentially 10 megapixels with 2 megapixels used strictly for improving low-light detail.

The Foveon chip represents a fundamentally different approach to a digital sensor- unfortunately it's only found in Sigma (yes, Sigma- good luck finding someone who uses those) cameras to my knowledge...

Here are two articles which explain the differences- if you're really into the underlying technology, it's interesting reading...

Answer 3

Yes, 10 megapixels in all brands is exactly what it says it is.
However, not all brands have the exact same photo quality. Some are better than others, which is usually determined by the quality of optical lens used, and also the sensor and processor which is inside the camera.
Canon is probably at the top of the list...many of it's cameras are very good (that's why it sells more cameras than any other brand). There are some brands I would never ever consider buying because their photo quality is not good enough.

Answer 4

yes ..are differences in how the sensor is made to have those 10 Megapixels.
Not all digital camera are using CCD.

there is
a. The Foveon Sensors from Sigma where 10 Megapixels are counted different than regular array sensor type.
b.Color Filter Array Sensors = CMOS, JFET LBCAST and CCD

Answer 5

10 megapixels is 10 megapixels regardless of the brand

Answer 6

the pixel count is dependent on the chip that is light sensitive used in the camera. regardless of whether it is a ccd chip or cmos chip 10 megapixels is the same in all camera's, the main difference in camera quality is the lens and other features that the camera has.

Answer 7

sorry i have to add my $0.02....

most of those answers are correct

another thing to note is that some 'cheaper' camera's will say(using your example) 10megapixels and it might say 'interpolated' which means that it's not actually 10mp ccd/cmos in the camera. it could be less than half of what it's stated to have...

in otherwords the camera could take a 5MP picture and make it bigger so it will be a 10MP picture, quality will look significantly different, because the extra pixels will be 'calculated'/guessed

Answer 8

the dazzling image readability relies upon on 3 worry-loose components: The form of Mp. the customary of the digital camera lens. the customary of the sensor. i take advantage of a 6.1Mp DSLR. yet i take advantage of it with a expert lens. And the sensor is solid. i could say the print at A4 length could equivalent or exceed that of a customary P&S (element and shoot) digital camera of 10Mp. Rule of thumb is that 6.1Mp is solid adequate for A4. you like approximately 10Mp for A3 length yet then your lens would desire to be of expert high quality and the sensor would desire to be of expert or semi-professional variety. I truthfully have a digicamcorder with a sprint lens that takes photographs at 5Mp. yet my 2.1Mp Panasonic P&S digital camera with a Leica lens takes photographs that are a minimum of thrice as clean. yet to respond to your question, while you're utilizing a expert lens and sensor, 5Mp with yeild photographs solid to A4 and 10Mp will yield photographs solid to A3.
