好多都看不懂.转过来看看,不合适就请版主删了吧....

One more foveon like Sony patent!

The three layer design from Sony


And here it is the next back-illuminated and three color layer Sony sensor patent! You can read the full (and very technical) description at freepatentsonline (Click here). It is not the first time we see such a “foveon like” patent. Sigma is currently the only manufactures that produces cameras based on that concept Like the new Sigma DP2s and SD15.

Here is the original patent description:
“In recent years, in the CCD image sensor or the CMOS image sensor, since the size of a pixel decreases and the number of photons incident on a unit pixel decreases, sensitivity deteriorates and thus a decrease in S/N occurs. In widely used pixel arrangement where red, green, and blue pixels are arranged on a planar surface, for example, the Bayer arrangement using the primary color filters, green and blue light does not penetrate a color filter in red pixels and is not used in photoelectric conversion. Therefore, sensitivity may decrease. Moreover, when a color signal is formed by executing an interpolation process between pixels, a problem of a false color may arise.
In order to solve these problems, Japanese Unexamined Patent Application Publication No. 2007-12796 discloses a solid-state imaging device in which green, blue, and red photoelectric conversion units are laminated in a depth direction of the same pixel. In the solid-state imaging device, a blue photodiode (photoelectric conversion unit) and a red photodiode (photoelectric conversion unit) are formed in the depth direction in a silicon substrate. In addition, the solid-state imaging device includes an organic photoelectric conversion unit in which a green organic photoelectric conversion layer interposed between electrodes is formed on the upper layer of the front surface of the silicon substrate on the side of a light incident side with a wiring layer interposed therebetween. According to the configuration disclosed in Japanese Unexamined Patent Application Publication No. 2007-12796, since a light loss does not occur in the above-mentioned color filter, the sensitivity is improved. Moreover, since the interpolation process is not performed between pixels, a false color does not occur.”

The patent description is very long and complicated and I would appreciate if you could help me to find some interesting details. Thanks!

P.S.: I don’t expect the A77 or NEX-7 cameras to feature such a sensor. But in my opinion “Foveon-like” sensors are the future!

Title:SOLID-STATE IMAGING DEVICE, METHOD OF MANUFACTURING THE SAME, AND ELECTRONIC APPARATUS

Document Type and Number:United States Patent Application 20110019042

Kind Code:A1

全色传感器的技术突破只能指望索尼松下这样的电子大佬，佳能指望不上，它就想老这么挤牙膏挤下去

但即使是3层或多层全色感应，也需要一定的密度，适马那块460W的明显密度不够，现在SD1提高了

sony公司本身说的，In recent years, in the CCD image sensor or the CMOS image sensor, since the size of a pixel decreases and the number of photons incident on a unit pixel decreases, sensitivity deteriorates and thus a decrease in S/N occurs.
这个总不会有疑问了吧

刚才看到说松下的专利号搞错，只能指望索尼哥了。。。
传感器不突破，打补丁似的新机实在没劲。。。

喜欢用高感拍人像？都是暗夜私房？

有说法好相像素太高时,用小光圈衍射斑会增强?画质下降,

好像在YY新的APS-C画幅CMOS是2400万像素,像素太高,

今后SONY的APS-C画幅用X3会早些来的吧?如像SIGMA的SD1有1600万像素点位,每个像素点位重叠3个绿,蓝,红像素,达到4500万像素,

平面单层的CMOS达到4500像素画质会下降,而X3多层CMOS效果会很好....

这个专利是背照上的，所以要用也是小dc/dv先用上。
