Smartphones Might Have 64MP and 108MP Sensors Soon, Credit Suisse Predicts

Smartphones

A technology and market analysis paper by Credit Suisse predicts smartphones with image sensors of over 100MP to be appear soon.

Excerpt from the report:

  • Demand from Huawei (32MP CIS mass production) and Xiaomi (long-term contract) has helped Samsung to gain market share in CIS.
  • Multi-camera smartphones are expected to comprise 65–70% of all models in 2019, up from 40% in 2018. Triple-camera models are expected to account for as much as 20% of all smartphone handsets (up from 1.5% in 2018).
  • The multi-camera percentage for Samsung Mobile is expected to reach 70% in 2019 (up from 21% in 2018).
  • Demand for 5MP CIS is booming due to the trend toward multi-camera smartphones (the 5MP CIS is an essential component of triple-camera handsets).
  • The CIS technology roadmap calls for further evolution towards higher megapixels, with development expected to bring 64MP in 2H 2019 and 100MP in 2020. The trend will increase the number of lenses required (though weight is an issue), demanding higher levels of cooperation between lens, module and AP manufacturers to achieve incremental improvements in image resolution.
  • With Line 11 undergoing conversion, Samsung is planning to boost the total monthly capacity of its CIS 300mm production lines to 75,000 units by end-2019 and 85,000 units by end-2020. No decision has been taken yet on whether to convert Line 13 to CIS production, but the general plan is to continue expanding capacity steadily.
  • CIS 300mm line development is underway at SK Hynix.

Canon Working On Global Shutter Sensor With Dual Memory Pixels, Research Paper

Global Shutter

Canon published a research paper in the Japanese Journal of Applied Physics, named “A 3.4 μm pixel pitch global shutter CMOS image sensor with dual in-pixel charge domain memory” (by Masahiro Kobayashi, Hiroshi Sekine, Takafumi Miki, Takashi Muto, Toshiki Tsuboi, Yusuke Onuki, Yasushi Matsuno, Hidekazu Takahashi, Takeshi Ichikawa, and Shunpike Inoue).

From the paper’s abstract:

In this paper, we describe a newly developed 3.4 μm pixel pitch global shutter CMOS image sensor (CIS) with dual in-pixel charge domain memories (CDMEMs) has about 5.3 M effective pixels and achieves 19 ke− full well capacity, 30 ke−/lxcenterdots sensitivity, 2.8 e- rms temporal noise, and −83 dB parasitic light sensitivity. In particular, we describe the sensor structure for improving the sensitivity and detail of the readout procedure. Furthermore, this image sensor realizes various readout with dual CDMEMs. For example, an alternate multiple-accumulation high dynamic range readout procedure achieves 60 fps operation and over 110 dB dynamic range in one-frame operation and is suitable in particular for moving object capturing. This front-side-illuminated CIS is fabricated in a 130 nm 1P4M with light shield CMOS process.

How To Make A Working Lens Out Of Sand And Rocks

If you are particularly keen to difficult DIY projects, this one may be for you.

Andy George of How To Make Everything redefines the concept of DIY with this project: a lens build from scratch using raw sand, rocks, and metal, and a huge amount of skills too, I guess.

Previously, Andy built a pinhole camera, as you can see in the video below.

Not satisfied with the pinhole camera, Andy decided to build a lens from the scratch. Well, it took him a dozen attempts before getting it done right. Guess making your own glass isn’t everyone’s thing. The video below explains all steps. Enjoy.

The Evolution Of Autofocus By Comparing Canon EOS R, Sony a7 III and Panasonic G9 Technology

Autofocus

We all know Canon has the best on sensor AF, Dual Pixel AF. But there are other AF technologies.

The video below by Gerald Undone compares the technology behind autofocus systems like Canon’s Dual Pixel AF in the new EOS R, the hybrid phase-detection in the Sony a7 III, and the Depth from Defocus Contrast Detection found in the Panasonic Lumix G9. Enjoy.

Canon EF 400mm f/2.8L IS III Teardown (Lens Rentals)

Canon EF 400mm

Roger Cicala and Aaron Closz of Lens Rentals disassembled the Canon EF 400mm f/2.8L IS III lens, a lens that costs like a used car.

From their conclusion:

The spring-loaded adjustable collar collection is something of a mystery to us and will remain so until we can spend some days doing optical adjustments on one. The use of the same motor as the RF lens is very interesting in several ways. Only some more tear downs will tell us if this is just a superior motor type that Canon is going to use in all electrically focused lenses (I suspect this is probably the case), or just in lenses with a lot of glass in the focusing element (another likely thing).

Canon has really been very quiet about this lens, despite the known changes inside. I had a lot of trouble finding out which elements are fluorite (two of them are, apparently). There has been some talk about improved focusing speed and accuracy, which I assume has something to do with the new electronic focus system, but not much.

The teardown is explained step by step with a lot of pictures, see it here.

Canon Explains The Advantages Of The Larger Mount On The Canon EOS R

Eos R

DCWatch posted some information about an internal Canon presentation.

The benefits and advantages of the large diameter of the RF mount featured on the Canon EOS R are discussed. The main reason is that the RF mount allows for a new and improved lens design.

Apparently, Canon had a try to use the EF M mount for their EOS R full frame mirrorless camera (machine translated text):

Initially, Canon also considered to realize a 35mm full size with the EF-M mount of the APS – C mirrorless “EOS M” series, but satisfactory results were not obtained, such as no performance aimed at . And since the system becomes large when unnecessarily increasing the mount diameter, we actually designed multiple lenses, decided to 54mm while looking at the balance of optical merit and size, the strength of the camera and so on.

This didn’t work out well, as it seems.

Canon sees these main advantages of the larger mount:

  • more flexibility on where the optical elements have to go
  • larger elements can be placed closer to the sensor
  • lenses are easier to design
  • complex lenses like the RF 50mm f/1.2L and 24-70mm f/2L are feasible
  • vignetting and other optical issues are better controlled

Note that while most of the above points would have been technically done also with the EF M mount, Canon clearly decided to go for the new mount type on the Canon EOS R because of the many advantages.

Some rumor outlets still push the rumor that Canon might release an APS-C model in the EOS R line-up; that’s not going to happen.
