Mobile CIS Market Decline Predicted

Image Sensors World        Go to the original article...

IFNews quotes Sigmaintell forecast saying that mobile CIS market starts to shrink after the peaking in 2021:


"With the continuous innovation and upgrading of technology and the promotion of 5G networks, multi-camera 2020 will increase the function of video shooting. It is expected that starting from the second half of 2020, the multi-camera + ToF ranging technology will slowly start to enhance the effect of background blur. In addition, post-shooting ToF combined with AI algorithms has the opportunity to improve the accuracy of indoor navigation, which is also a key focus of technological development. Therefore , Sigmaintell believes that the mainstream rear camera in the future will develop in the direction of main camera wide angle + video shooting + large telephoto + ToF.

The upgrade of 48M and above pixels accelerated, with a market share of about 9% in the third quarter. Among them, Sony accounts for approximately 41%, Samsung accounts for approximately 56%, and OV accounts for approximately 3%. Due to the accelerated replacement of 48M and the insufficient production capacity of high-resolution camera sensor wafers, Sigmaintell expects supply shortages from Q4 to Q1 2019.

According to Sigmaintell data , global shipments of 48M camera sensors will exceed 450 million units in 2020.

IFNews quotes Mynavi review of Sony invited presentation at 2019 AEC/APC Symposium Asia on "The manufacturing and future of Sony CMOS Image Sensor."

"Sony aims to become a smart factory and is working on the following seven projects.
  1. Intelligent manufacturing equipment (utilization of edge computing) = Monitors the sensor output of all manufacturing equipment, automatically detects small fluctuations by machine learning, and performs feedback forward.
  2. Value chain (market submission survey, demand forecast, customer information collection) factory production management based on information)
  3. Intelligent MES (Manufacturing Execution System)
  4. Innovative energy system
  5. Integrated IT system
  6. Smart purchasing activities for parts and materials
  7. Smart engineering system (use of big data)
...a number of low-priced surveillance cameras are installed in the manufacturing process, and in combination with AI, efforts are being made to monitor process abnormalities in real time."


The same Symposium also published 2015 Sony paper on Vth variations.

More About New Snapdragons Imaging Features

Image Sensors World        Go to the original article...

Tech2 publishes photos from Qualcomm Summit held on Dec. 3-5, 2019 in Maui, Hawaii. Few interesting pictures, more are in Judd Heape, Qualcomm camera products manager, presentation:

Snapdragon 865 ISP development took 3 years:


Not sure what kind of lower than 1mW power image processing it can perform:


Now, Spectra ISP supports quad CFA processing at the hardware level. No need to convert it to the Bayer pattern:


Few other slides:


Qualcomm also announces Snapdragon XR2 AR/VR Platform supporting 7 cameras on a headset:

"With XR, for the first time a user can be virtually teleported to a new environment. To do this accurately and efficiently, the Snapdragon XR2 introduces support for seven (7) concurrent cameras and a custom computer vision processor. Multiple concurrent cameras enable real-time and highly accurate tracking of the head, lips and eyes together with 26-point skeletal hand tracking. Computer vision provides highly efficient scene understanding and 3D reconstruction. Together, these features allow users to be transported to new environments where they can intuitively interact within a digital world."


Even 7c and 8c compute platforms have quite impressive camera specs:


Qualcomm's competitor Mediatek announced its 5G platform Dimensity. The platform utilizes big-little processing approach featuring "the world’s first 5 core ISP in a unique 3 big plus 2 small design. It offers the best performance to power efficiency index by matching the right size sensor to the most appropriate ISP."

Snapdragon 865 & 765 Imaging Capabilities

Image Sensors World        Go to the original article...

Qualcomm announces Snapdragon 865 mobile platform with upgraded camera features:

"Gigapixel Speed ISP: The Snapdragon 865’s ISP operates at staggering speeds of up to 2 gigapixels per second and provides brand-new camera features and capabilities. You can capture in 4K HDR with over a billion shades of color, capture 8K video, or snap massive 200-megapixel photos [Old Snapdragon 845 announced in 2017, as well as the newer 855 and 855+ platforms already supported 192MP]. You can also take advantage of the gigapixel speeds to slow things down and capture every millisecond of detail with unlimited high-definition slow-motion video capture at 960 fps. And now, for the first time ever on a mobile platform, Dolby Vision for video capture creates brilliant HDR footage that’s primed and ready for the big screen. In tandem with the 5th generation Qualcomm AI Engine, the gigapixel speed ISP can quickly and intelligently identify different backgrounds, people, and objects, so they can be treated individually for a truly customized photo."

Gpixel Announces Red Fox NIR-Enhancing Technology

Image Sensors World        Go to the original article...

Gpixel announces a NIR-enhanced version of its GMAX0505 sensor, a 26MP global shutter CMOS sensor in a square 1.1” optical format. The GMAX0505 and the new NIR-enhanced GMAX0505RF are part of Gpixel’s 2.5 µm pixel family of pin-compatible C-mount sensors for industrial and scientific applications.

Typically, NIR sensitivity is enhanced by increasing the thickness of the sensor’s epitaxial layer. However, this impacts MTF and limits the effective resolution of the sensor. The new Red Fox process modifies the
sensor’s sensitive layer to achieve an optimal balance between NIR sensitivity and MTF.

The GMAX0505RF achieves a QE of almost 34% at 850 nm and 14% at 940 nm. In comparison, based on publicly available EMVA test data some competitive image sensors only offer a QE of 20% at 850 nm. This equates to a 70% improvement in QE performance.

As the Red Fox process can be applied to any GMAX products, Gpixel’s anticipates other GMAX RF products will be released in the near future. Engineering samples of the GMAX0505RF are available now for evaluation.
