Инфо за това , как стоят нещата от техническа гледна точка при съвременните камерафони :
"OK, so the camera is 8 MPix (3265x2448 pixels). Is it? It's actually much more correct to say that the IMAGING SENSOR is 8 Mpix. But there's also a lens covering it, not to mention that protective piece of plastic on top of it. While the sensor indeed generates 8 Megapixel images, the actual detailness of pictures highly depends on the optical resolution of the lens, i.e. its ability to resolve detail (optical quality of the glass letting more or less detail pass through it to the sensor). The truth is, that even mid-range dSLR lenses of diameters measured in centimetres often have problems with delivering optical resolution matching high resolution sensors, so how can a lens of a mobile phone with 2 mm diameter do it? Shortly speaking, it can't. This means that while the resulting image file consists of 8 million pixels, the level of detail of pictures is actually by an order of magnitude lower. This is why the images appear sharp when watched at magnifications lower than 1:1 but turn out to be somehow smooth or a little bit blurry at 100% magnification. It's a result of the optical resolution of the lens being lower than the resolution of the sensor, causing that each group of several neighbouring photosites (pixels) of the sensor get the same piece of information (detail). So, shortly speaking, the sensor creates 8 Megapixel files but with level of magnitude less worth detail.
Now a word of clarification. I am mentioning this NOT to indicate that the camera of the Omnia HD is a bad one. As I wrote, it's actually the best camera phone on the market and the above rant about optical resolution of the lens does not change it at all. It's just to help you understand how cameras work. I described it in this review and not in any previous one of any other camera phone simply because it's one of the first camera phone actually WORTH getting into such details. Even though the actual level of detail is lower than the advertised 8 Megapixels, it's actually not unique to this phone model or manufacturer but it's a common thing to all camera phones. With one important difference: the lens of the Omnia i8910 is a "high definition" one, i.e. optimized to support recording of HD 720p video, which is 1280x720 i.e. about 1 Megapixel. This ensures that the optical resolution of the lens at least isn't lower than that, which is not guaranteed by lenses of other camera phones."

Каква е резолюцията на камерафона ви?
Re: Каква е резолюцията на камерафона ви?
Поредната глупост от човека, който е твърде възрастен, за да спори с мен.
Аналогова камера явно е съвсем различно понятие от лентов фотоапарат. Умно.
Относно максималната резолюция, аз по принцип не отказва някой-друг допълнителен мегапиксел, ставайки въпрос за фотоапарати. При телефоните ме дразни, че наблягат основно на това, а не на другите по-важни характеристики. Иначе съм с 1920х1200 резолюция на екрана и 2МР в никакъв случай не ми стигат.
Снимам с 10МР, максималната резолюция на фотоапарата ми.
