To me anything more than 12 MP is not going to be good unless, you are a professional(I mean real professional photographer, not some monkeys with DSLRs!!!). 12 MP is more than enough for a mobile - I would not recommend to go for a mobile with anything greater than 8 MP.Arun Kumarhttp://hindisms.org/sms/hindi-love-smsnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-58508802286485358792012-02-28T23:07:27.736+02:002012-02-28T23:07:27.736+02:00One of the figures Vladimir included indicates tha...One of the figures Vladimir included indicates that even though there are north of 41 million pixels, the two operating modes are a 4:3 mode using 38.391 million pixels and a 16:9 mode using 33.647 million pixels. The specifications give lossless zoom figures of 3x for still images and 4x for full HD 1080p video. At 30 frames per second, the 16:9 mode would have something like 1 Gs/sec A/D throughput, which suggests to me that there's some immediate binning to get down to data rates that are easier to digest. Then you could get the lossless zoom by omitting some of the binning operations. It doesn't seem likely to me that the video would allow lossless zoom after capture. I would guess if the chip can handle 2 Mpixel at 30 fps, full-resolution stills would take a little more than half a second each.CDMhttps://www.blogger.com/profile/16405088162729045793noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-79939581835136620702012-02-28T22:48:39.085+02:002012-02-28T22:48:39.085+02:00The statement that the sensor was "developed ...The statement that the sensor was "<i>developed with Toshiba and other Nokia partners</i>" appears on many sites all other the Net.

Pushing the images a lot did not show any noise issues, so I wonder where you saw this awful noise. Considering the level of details and low noise levels, it is hardly a marketing gimmick.<br /><br />(Unfortunately the phone doesn't seem to allow raw image output, so performance data of the sensor itself is not possible to get.)<br /><br />Also, it is the size of the sensor and the quality, not size of the pixels which are relevant to the noise in the output image.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-3213383827059310222012-02-28T19:53:03.987+02:002012-02-28T19:53:03.987+02:00http://www.arnnet.com.au/article/416662/nokia_unve...http://www.arnnet.com.au/article/416662/nokia_unveils_41-megapixel_imaging_sensor_technology<br /><br />This article seems to confirm that its made by Toshiba?<br /><br />Interesting to know the power consumption for the 38MP mode or even the 8M/5M modes scaled down from higher resolution?<br />Any idea on the # of CSI-2 lanes?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-77930000772419726202012-02-28T15:17:19.828+02:002012-02-28T15:17:19.828+02:00The noise in the sample images that are @ISO50 is ...The noise in the sample images that are @ISO50 is awful, and that's what you get from 1.4um pixels.<br />41mpx is only a marketing gimmick, so that the user will get a better 'digital zoom'.

While digital zoom and re-framing etc in post are useful they are covering for a lack of thought when the user presses the shutter. There is the argument that as cameras become ever more automated it forces the loss of knowledge from the user, thereby prompting more automation. <br /><br />The use of oversampling is a good one, reducing the noise of the 7:1 output pixel is a nice touch, probably will give a nice colour rendition too depending on the interpolation algorithm. It will be interesting to see low light images from the sensor.Anonymousnoreply@blogger.com
