Yole Developpement analyst Pierre Cambou posts his guesses on what technology might be used in Apple iPhone 8 3D camera:

"Until earlier this year everyone thought 3D cameras would appear on the rear of Apple’s new iPhones, as is the case in the Lenovo Phab 2 Pro, in order to develop Augmented Reality applications. This changed radically when Ming Chi Kuo, an analyst from KGI Securities, confirmed in April 2017 that there would be a front 3D camera... Most analysts speculate that this camera would exploit “structured light”, because of Primesense’s involvement. However, Yole maintains its original idea of a Time of Flight (ToF) camera on the front due to the nature of the application, which is to be a new revolutionary user interface."

Digitimes comments on CSP packaging company Xintec ongoing losses:

"Xintec used to rely on orders from OmniVision. However, the acquisition of OmniVision by a group of China-based investors led by state-owned Hua Capital Management in 2016 has had an adverse impact on Xintec's business in the image sensor field, the observers indicated. Xintec is also facing increased competition from its China-based rivals in the fingerprint sensor sector.

Nevertheless, Xintec is reportedly among the companies joining Apple's and Qualcomm's 3D sensing supply chains, which also included its largest shareholder Taiwan Semiconductor Manufacturing Company (TSMC). Xintec may begin to see the light at the end of tunnel as early as 2018, the observers noted."

Macrumors and IF News quote KGI securities analyst Ming-Chi Kuo saying that Apple 3D camera technology is 1.5-2 years ahead of Qualcomm one. Apple is expected to use 3D frontside camera in one of its upcoming iPhones for face recognition and user interface.

"According to Kuo, Qualcomm is dealing with immature algorithms and an unfavorable hardware reference design for smartphones due to form factor design and thermal issues. Qualcomm may also be impacted by Apple's choice of suppliers. Many key component suppliers have already allocated resources to Apple, so Qualcomm has to find different suppliers in order to obtain sufficient resources."

So far, only Xiaomi 2018 flagship phone is expected to use Qualcomm 3D solution with volumes less than 10M units, according to Kuo. Even this might be cancelled, depending on the new iPhone success.

Sony patent application US20170229493 "Pixel circuit and imaging apparatus" by Kouichi Harada and Toshiyuki Nishihara proposes dark current reduction in bulk charge modulated device (BCMD).

"...the above image sensor needs to read 1000 times in one frame for example, and has problems of increase in read voltage and increase in read time. Also, as the number of reads per frame increases, dark current of the FD increases proportionally. As a result, the dark current of the FD becomes the main component of the dark current of the pixel. The dark current of the FD is unable to be reduced easily, and thus even if the conversion efficiency can be set to 600 μV/e−, the accuracy of detecting one photon is reduced. If there is no FD, the accuracy of detecting one photon is improved.

...According to the present technology, it is possible to obtain an excellent effect that the dark current of the FD in the image sensor is eliminated, and that the conversion efficiency of converting the electric charge to a voltage can be improved."

BASF spinoff Trimamix publishes an arxiv.org paper "Focus-Induced Photoresponse: a novel optoelectronic distance measurement technique" by Oili Pekkola, Christoph Lungenschmied, Peter Fejes, Anke Handreck, Wilfried Hermes, Stephan Irle, Christian Lennartz, Christian Schildknecht, Peter Schillen, Patrick Schindler, Robert Send, Sebastian Valouch, Erwin Thiel, and Ingmar Bruder.

"Here we introduce Focus-Induced Photoresponse (FIP), a novel method to measure distances. In a FIP-based system, distance is determined by using the analog photoresponse of a single pixel sensor. This means that the advantages of high-density pixelation and high-speed response are not necessary or even relevant for the FIP technique. High resolution can be achieved without the limitations of pixel size, and detectors selected for a FIP system can be orders of magnitude slower than those required by ToF based ones. A system based on FIP does not require advanced sensor manufacturing processes to function, making adoption of unusual sensors more economically feasible.

In the FIP technique, a light source is imaged onto the photodetector by a lens. The size of its image depends on the position of the detector with respect to the focused image plane. FIP exploits the nonlinearly irradiance-dependent photoresponse of semiconductor devices. This means that the signal of a photodetector not only depends on the incident radiant power, but also on its density on the sensor area, the irradiance. This phenomenon will cause the output of the detector to change when the same amount of light is focused or defocused on it. This is what we call the FIP effect."

Coolpad, one of the large China-based smartphone makers that uses 13MP monochrome + 13MP RGB dual camera in its devices, says about the benefits of that configuration:

"The two lenses may look the same, but they have very different functions. One shoots in RGB to produce a color image, while the other takes care of the monochrome images. The monochrome lens brings out the detail, and engage more light than the RGB lens when in low-light condition, which takes care of the colors. The Dual camera 2.0 technology in Cool Dual actually enhanced the overall clarity of the image by 20%, help reduce image noise by 8% and improved brightness by 20%. “With these, we believe the real dual 13MP cameras brings us smart framing and the 6P lens gives customers the best quality of pictures”, said Jeff Liu, Coolpad Group CEO."

Pinnacle Imaging Systems launches Denali-MC HDR ISP IP core said to preserve a scene’s color fidelity and full contrast range throughout the tone mapping process, all without producing halos, color shifts, and undesired motion artifacts.

Denali-MC provides a 16-bit data path capable of producing 100 dB or 16-EV steps of dynamic range. Denali-MC HDR IP completely eliminates halo artifacts and color shifts, and mitigates the ghost artifacts and transition noise often seen when merging multiple exposures. This allows Denali-MC to capture up to four exposure frames from 1080p video at 120 fps, while merging and tone mapping at 30 fps in real time. For applications requiring faster output frame rates, Denali-MC also supports a two frame merge mode exporting at 60 fps. Furthermore, Denali-MC can support up to 29 different CMOS sensors, including 9 Aptina/ON Semi, 6 Omnivision and 11 Sony sensors, and 12 different pixel-level gain and frame-set HDR methods, and is said to be easily ported to the most widely-used logic platforms.

HDR-Specific Features:

• Advanced motion compensation algorithms virtually eliminate HDR merge artifacts and transition noise
• Proprietary Locally Adaptive Tone Mapping technology preserves color fidelity through the entire tonal range without creating halo artifacts or color shifts
• Automatic EV bracketing
• Automatic or manual contrast adaptation for global or local video correction
• React concurrent still frame and video capture feature, non-destructively extracts four source LDR Bayer images, merged Bayer HDR, tone mapped Bayer or HDMI RGB still frames without interrupting video
• Ability to capture separate HDR and tone mapped output video streams concurrently (ideal for ADAS applications)
• Two or four frame multiple exposure merge (with Sony IMX290 implementation)
• HDR + Low illumination capabilities with Sony IMX290 sensor enable 24/7 round the clock video capture capabilities for any contrast and lighting condition

“At Fairchild Imaging, we have been very impressed with the Denali-MC ISP state of the art locally adaptive tone mapping (LATM) functionality,” said Vern Klein, Director of Sales and Marketing Fairchild Imaging. “I’ve seen first-hand how they can make a great sensor perform even better in its native WDR mode. Camera manufacturers will benefit from this technology, which provides high quality HDR functionality without requiring companion chips or additional hardware cost to support the algorithms.”

“Pinnacle’s new Denali-MC HDR ISP is a significant achievement addressing HDR video requirements in surveillance, monocular camera automotive markets and machine learning with its customization, artifact compensation, color accuracy and quantifiable high dynamic range of 100 dB,” said Paul Gallagher, image sensor industry veteran and futurist. “Camera system developers in these markets would benefit from utilizing these attributes of the Denali-MC ISP as a standalone ISP or integrate Pinnacle’s HDR IP blocks within their existing ISP.”


Pinnacle also publishes a video demo of its HDR capabilities (short version, long version):
