Unfortunately I do have to agree with you ....<br />But about 15 years ago I was part of the ISSCC selection committee for image sensors. The committee decided to reject papers that had not listed the conversion gain, and to inform the authors of rejected papers about this request. This way of working was very efficient. But since 2010 I am no longer involved in ISSCC, so I do not know the process of today.Albert Theuwissen - Harvest Imagingnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-69523974432340490212020-11-21T20:19:12.073+02:002020-11-21T20:19:12.073+02:00The figures of merit are there and we all know tha...The figures of merit are there and we all know that. Hiding the true performance is deliberate. "Specmenship" driving by the desire of avoiding to be benchmarked against competition. We all know that and none of us will change it.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-67823623511527008602020-11-21T12:47:43.413+02:002020-11-21T12:47:43.413+02:00This hasn't changed much in 40 years starting ...This hasn't changed much in 40 years starting with CCD specs. Sometimes even in IEEE TED or JSSC (or IEDM or ISSCC) papers the full conditions of measurement or hidden parameters are not revealed. But as long as you mention this, here is an old article I wrote in 1999 talking about this issue, at least a little bit:<br />http://ericfossum.com/Publications/Papers/CMOS%20digital%20cameras%20need%20new%20figures%20of%20merit.pdf<br />Eric R Fossumhttps://www.blogger.com/profile/09413387887974939684noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-62357775142194104892020-11-21T10:53:00.749+02:002020-11-21T10:53:00.749+02:00I am always surprised that companies express the s...I am always surprised that companies express the sensitivity of their sensor in mV/lux.s without telling us anything about the spectrum of the light source, exposure time, etc. Moreover, I do not know these sensors, but I guess that they have all digital outputs. So a customer is even not able to measure the output in mV, only digital numbers are available at the output. <br />In other words, the performance of the sensors are specified in an unknown condition of light input, unknown condition of sensor operation and in a unit that nobody can measure. <br />Why not simply give us numbers that we can work with ... ?Albert Theuwissen - Harvest Imagingnoreply@blogger.com
