Sony Defines its Starvis Sensor Category

Sony publishes a short presentation explaining what sensors belong to Starvis class:

  1. Starvis - not Starviz.

    It is a short for "Vis"-ibility under "Star"-light.
    This is an old PPT, but IMX 183 / 226 / 290 / 390 and so on shows the technical direction. On of the best performing consumer pixel tech on my desk the last years.

  2. This information does look a little old. I wonder how the new IMX462 compares with IMX290.

    1. PPT is old. Around 5 years. And we laught about the bad photoshopped images. Night simulation by changing gradation of stockphotos. Poor.

      I think, the DCG feature is one key to success. Sure, also the pixel itself. The 462 is from last year and should be improved, compare to the quite old 290.

    2. IMX390 has been announced in 2017, but its mass production started just a year ago:

  3. The IMX390 is nice imager (on my desk here) but I think the new 490 is better due to 2x DCG and Split PD. HDR combining is much smoother in blending between the 4 images. Keyword: Visible SNR drop. Anyway. ISP knowlegde is much more important in the future.

    1. Just to add, there is an excellent HDR sensors review by Dana:

      I'm still thinking how to post it in the blog. There are too many good slides and it's hard to select a subset.

    2. Why only 2x DCG? it doesn't help much.

  4. Dear Sony,
    the age of CCD is long gone, so could you please stop using mV to quantify sensitivity? None of your sensors make voltages available at the output, so even if the measurement conditions were repeatable, no one could verify the result.
    I get that even though the image sensor market is rapidly evolving some traditions are hard to leave behind, best example would be the quite flexible sensor diagonal "inch". But when seeing such slides I can not be the only one who thinks "Thank you, but where is the EMVA1288 data?"

  5. Dear Sony,

    The age of CCD is long gone, so could you please keep using mV to quantify sensitivity considering that it's the easiest way to compare old and new sensors performances...

    Thanks !
