What do you do with the old mobile phone after changing the model?I don't feel like throwing away the memories of my youth, so I still have it when I moved to Germany.

Specifically, SH901IS, SH704I, and F04A are in the corner of the shelf, and sometimes they are rarely touched.When you open it and turn on the power (it is really charged), the sensation of the time is revived, and it is very nostalgic, but when you look at the screen and photos, you will feel the big difference from the current smartphone.

I think it's because I sometimes do that, but last month, when I interviewed an announcement that Omnivision has developed an image sensor "OVB0B" for smartphones for smartphones, "Oh, have you finally come here?"I felt it.

"OVB0B" is a pixel size of the world's smallest "company" with 200 million pixels..It is a product for high -end smartphones that are realized at 61 μm and also has a 16 -cell vining function and a phase difference detection function.This is not the first time that Samsung Electronics has announced "ISOCELL HP1" in September 2021 for the 200 million pixel image sensor itself ( * ISOCELL HP1 pixel size is 0..64μm).The smartphones equipped with the 200 million pixel image sensors of both companies are expected to appear later this year.

When I heard again, "200 million pixels," I was deeply moved by saying, "I was happy with about 1.3 million pixels until this time (10 years ago)."

By the way, in recent years, the polensification and microscopification of such smartphone sensors for smartphone sensors is mainly led by Samsung, which is the second largest market share in the mature smartphone market, has differentiated from competitors.It has been advanced.
