Sony DSC HX80 Sensor

How does 1/2.3 figure in ? Sensor sizes are expressed in inches notation because at the time of the popularization of digital image sensors they were used to replace video camera tubes. The common 1" circular video camera tubes have a rectangular photo sensitive area about 16mm diagonal, so a digital sensor with a 16mm diagonal size is a 1" video tube equivalent. The name of a 1" digital sensor should more accurately be read as "one inch video camera tube equivalent" sensor. Current digital image sensor size descriptors are the video camera tube equivalency size, not the actual size of the sensor. For example, a 1" sensor has a diagonal measurement of 16mm. Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system brings a result approximately 1.5 times the length of the diagonal of the sensor. This “optical format” measure goes back to the way image sizes of video cameras used until the late 1980s were expressed, referring to the outside diameter of the glass envelope of the video camera tube. The actual sensor size is much smaller than the camera companies publish – about one-third smaller." For example, a camera advertising a 1/2.7" sensor does not have a sensor with a diagonal of 0.37"; instead, the diagonal is closer to 0.26. Your 1/ 2.3” sensor will have a diagonal measurement of approximately 7.66mm. Fascinating. I had always guessed that might be the derivation, nice to have it confirmed. Imperial tubes of course because that was in the days when the USA was driving the technology. |

No you didn't. You most definitely didn't. You cited two wep pages which the OP has clearly failed to read. You could, if you had been so motivated, pointed out that the second web page said that the maximum resolution is 4896 x 3672 and the sensor was sized 6.17 x 4.55mm. That would have been extremely helpful and would have immediately answered the OP's questions. But no, rather than pointing out that the specific information was in the 2nd URL you kept on being difficult .... -- Regards, Eric Stevens |

No you didn't. You most definitely didn't. yes i very definitely did, and more than once. You cited two wep pages which the OP has clearly failed to read. it's not my problem if someone else does not read the provided links, or if they did ask questions if they don't fully understand it. You could, if you had been so motivated, pointed out that the second web page said that the maximum resolution is 4896 x 3672 and the sensor was sized 6.17 x 4.55mm. which is exactly what i did when it became apparent he was still confused.

With a bit of willingness on your part you could have made it in one. also wrong. the problem was that the original poster didn't understand what aspect ratio meant and cannot do basic math. |

the problem was that the original poster didn't understand what aspect ratio meant and cannot do basic math. I knew what aspect ratio was before you were born. As a license professional engineer, I'm confident that my math skills well exceed yours. |

I knew what aspect ratio was before you were born. you don't know when i was born, therefore that statement is false on its face. OK, I'm 72 and first dealt with aspect ratios in regards to my hobby astronomy, in the mid 1950s. if you knew what aspect ratio meant, then you would know what calculation to do from the specs *and* would be able to determine its shape (which is always rectangular). As I said, I hadn't seen the specs, when I posted my questions regarding the sensor. Just thought someone would know some quick answers. As a license professional engineer, I'm confident that my math skills well exceed yours. given that you admitted to not understanding what aspect ratio is and how to calculate it, that statement is clearly false. Where did I say that I didn't know what aspest ratio was ?! I only asked what the aspect ratio of the sensor was. Again, at that point I hadn't seen the specs. BTW, my math aspecialty is Differential Equations. What's yours ? |

What's yours ? diffeqs has nothing to do with aspect ratio, which is nothing more than division, something a grade school kid can do. |

Yes of course BUT, as I've stated several times, I hadn't seen those specs at the time I posed my questions. If I had, then it would all be a non-issue. AND, I thanked you for giving me the site with the info, which I had not had previously. you certainly saw the specs when i posted links to them, yet you still failed to determine the aspect ratio, which means you really *don't* understand it. NO, once I saw the dimensions, I obviously had the answers to my questions, but not before. diffeqs has nothing to do with aspect ratio, which is nothing more than division, something a grade school kid can do. No indeed, not much to do with aspect ratios, but I was challenging your assertion that I lacked math capabilities. Rest assured that I well knew that aspect ratio is the height divided by the width of the sensor. When I see a fat person, I always tell my wife, that they have a low aspect ratio. |
