That'd give less than 0.35 e- leakage and therefore negligible noise penalty. Even at 10 ms read (1/100fps) you'd only get 3.5e- leakage resulting in 1.9e-rms - being therefore indeed insignificant compared to the 16e-rms.Andreas Süssnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-43000628917922279252016-09-21T19:04:13.695+03:002016-09-21T19:04:13.695+03:00Not true.

In this case, the dark current will be accumulated during the readout time, say, 20ms.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-1732000527880865052016-09-21T17:14:05.303+03:002016-09-21T17:14:05.303+03:00- 350 e-/sec "at 50 deg C", so about 100...- 350 e-/sec "at 50 deg C", so about 100 e-/sec at room temp, which still large<br />- Global shutter = fast exposure time, so dark current doesn't matter too much. The sensor has a noise of 16e-'s, so a couple of electrons don't matter.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-72166123552142910972016-09-21T11:45:51.860+03:002016-09-21T11:45:51.860+03:00350e/sec of dark current is huge.350e/sec of dark current is huge.Anonymousnoreply@blogger.com
