Sony patent discloses global shutter technology and foveon like sensor.

Sony fulfilled a new patent describing a sensor with global shutter (Click here to see the original patent). This is Sony’s description:
“In the CMOS type image sensor, the photoelectric conversion unit reads out the signal charges for each pixel or for each row where a plurality of pixels is arranged. In this case, exposure time for accumulating the signal charges is difficult to match in all the pixels, and thus in some cases, a captured image is distorted. Particularly, if the motion of a subject is great, this defect is noticeably generated. In order to prevent this defect from being generated, a “global exposure” is performed in which all the pixels start exposure at the same time and finish the exposure at the same time. The “global exposure” is performed by simultaneously driving all the pixels through an electrical control without using the mechanical shutter

The same patent describes also how Sony wants to increase the number of Megapixels without to lose image quality. It’s the “foveon” alike approach. It’s not the first time we see such a patent:
In order to realize the high sensitivity, there has been proposed one where a chalcopyrite based compound semiconductor film such as a CuInGaSe2 film with high light absorption coefficient is used in the photoelectric conversion unit (for example, refer to Japanese Unexamined Patent Application Publications No. 2007-123720).
In addition, there has been proposed a “lamination type” where photoelectric conversion units for respective colors are laminated and disposed in a depth direction perpendicular to an imaging surface, instead of disposing the photoelectric conversion units which selectively sense light beams of respective colors in a direction along the imaging surface. In the “lamination type,” each pixel senses not only light of one color but also light of plural colors. For this reason, a light sensing surface is extensively formed and thus use efficiency of light can be improved, thereby improving sensitivity (for example, refer to Japanese Unexamined Patent Application Publications No. 2006-245088).

 

Can’t wait to see such a sensor coming soon!!!

Merry Christmas SAR readers!

Dear SAR readers,

I am ready to spend my time with my family, and I want to share some very few words here. I am not going to stop to work on SAR in these days. Quite the opposite, I have some time off from my work and I am planning to think on a whole redesign of the website. If you want you can send me your suggestions to sonyalpharumors@gmail.com. I will also write a full 2012 Sony camera and lens prediction list. It will be a mix of rumors and speculation. And if there is no new Tsunami, Flood or Nucelar catastrophe like we had in that year I am sure Sony will be able to announce ALL the much expected FF cameras and lenses.

That said I wish all of you a peaceful Christmas, and a nice time with all the person you love! Thanks for all the great time you shared here on SAR this year!

P.S.: I hope most of you got the Sony NEX-7/A77/A65 camera in time to take pictures of the Christmas dinner (my NEX-7 didn’t arrive yet). Last check of  in Stock status:
A77 in Stock at BHphoto (Click here), Amazon Germany (Click here).
NEX-7 auctions on eBay US (Click here to see the seven auctions), eBay Germany (Click here), eBay Austria (Click here) and eBay France (Click here).

Interview with the Sony NEX-7 designers (New Tamron for NEX in Stock).

Sony Japan (Click here) posted the full English translation of the interview made with the Sony NEX-7 designers. I didn’t know that “All we had decided initially was that three dials would be used….It was essentially our only beacon in design“. Would love to know who had the idea…quite a genius that guy ;)

Meanwhile the first “european” NEX-7 is on auction on eBay (Click here). Fotomundus had five in Stock, but they are now sold out (one is mine…LOL). USA readers are far more lucky. There are now eleven(!) NEX-7 bodies for auction on eBay (Click here to see them all). This means the price will finally go down.
