Omnivision to Benefit from Selfie Trend

Image Sensors World        Go to the original article...

Barron's: Rosenblatt Securities‘s analyst Brian Blair forecasts:

"We believe the most critical trend for OmniVision’s business this year is what we are calling the selfie trend. The basic idea is that front facing cameras on smartphones have generally been VGA – 1MP over the last 5 years. We believe that this is shifting in 2015 to 5MP — 13MP sensors for front-facing cameras. We expect to initially see this at the high end of the market, but we anticipate the trend will quickly filter into mid-tier models as well. We recently saw evidence of this trend at CES with a few models that had 5MP – 13MP front facing cameras (from Samsung and HTC notably) and we expect MWC in early March to showcase numerous additional models. This trend is critical, as it meaningfully lifts dollar content per handset and raises overall ASPs/ revenues, and provides a bump to gross margins as well."

Image Sensors World        Go to the original article...

Intel publishes more info on its F200 structured light front camera.

RealSense F200 camera

The IR Laser Projector emits a structured pattern of Class 1 infrared light used to determine the dimensional characteristics of objects by the depth camera:

Laser projected structured light patterns are quite unusual

Intel explains that the right (green) pattern is, in fact, changing at fast speed, so that if one makes a picture of it at 1/30s exposure, it blurs into the left (gray) pattern. EETimes says that the projector emits 16 different patterns.

Yole Updates CMOS Sensor Market Report

Image Sensors World        Go to the original article...

Yole Developpment releases an update to its CMOS sensor report with the new market data:

"Driven by mobile and automotive applications, the CIS industry is expected to grow at a CAGR of 10.6% from 2014 - 2020, reaching a market value of US$16.2B by 2020."

"Automotive is the big story this year, as car manufacturers like Tesla, Nissan and Ford are showing off their first camera-enabled features. Market traction is particularly impressive, with most CIS players enjoying growth rates of 30% - 50%. But this is only the beginning, with most CIS players looking at this market, total revenue should reach US$800M in 2020 – for CIS sensors only. Automotive’s emerging importance promises profound implications for the CIS ecosystem. As CIS moves from a “for display” application towards a “for sensing” application, new players such as processor and software providers will become key partners for sensor design and marketing."

"Since 2010, Yole Développment has well documented the rise of back side illumination (BSI), which has now become a mainstream technology that’s captured more than 50% of CIS production... Size constraints in mobile have pushed 3D stacking BSI, which currently has 20% of the market."

ST SPAD Array Captures Light in Flight

Image Sensors World        Go to the original article...

ST 32x32 SPAD array developed under EU funded FP6 project Megaframe with University of Edinburgh and partners is the basis of Heriot-Watt University 20 billion fps-fast camera. The open access Nature Communications' paper "Single-photon sensitive light-in-fight imaging" by Genevieve Gariepy, Nikola Krstajić, Robert Henderson, Chunyong Li, Robert Thomson, Gerald Buller, Barmak Heshmat, Ramesh Raskar, Jonathan Leach & Daniele Faccio.

A laser pulse is reflecting off multiple mirrors, passing three times
across the field of view of the SPAD camera (35 35 cm2).
The same laser is used to create a trigger sent to the camera.
The SPAD camera collects scattered photons from the laser pulse.
The field of view does not contain the mirrors because the
scattered light coming from the mirror surfaces is much more
intense than the Rayleigh-scattered light during propagation.
The histogram indicates the time of arrival of the laser pulse as
measured by pixel (22, 21). The time frames, shown at 0, 1, 2, 3
and 4 ns, show the evolution of the pulse in time as it propagates
across the scene. The integration of all frames gives the total
path followed by the light, similarly to what can be acquired
by an EMCCD camera at maximum gain for an exposure time of 7 s.

A Youtube video shows the light propagation process:

Rambus CEO on Lensless Image Sensor Platform

Image Sensors World        Go to the original article...

SeekingAlpha: Rambus CEO Ron Black talks about lensless image sensor project status: "Coming up in early March in Barcelona Spain is the Mobile World Congress or MWC, which is the premier wireless conference. If you recall last year at the conference, we launched our Lensless Smart Sensor, the smallest, lowest power, lowest cost image sensor on the planet and won a Best of Show from Tom's Hardware, something that frankly surprised us and that we're exceedingly proud of.

Last year's show sparked enormous interest, especially with press from prominent outlets such as the MIT Technology Review and Gizmondo, and we work inundated with interest from all segments of the industry from medical to automotive, to industrial, to consumer.

Many of the parties requested us to provide a platform for the industry at large and especially the maker community in which to innovate. At the risk of leaking too much, we will be launching such a platform at this year's MWC and hope to generate even more interest and more importantly some commercial relationships for the Lensless Smart Sensor this year and next.
"

Later, he says that Rambus is considering "various monetization options for our Binary Pixel and Lensless Smart Sensor solutions."

Omnivision patent application US20150015757 "Image sensor pixel cell readout architecture" by Trygve Willassen says "The sum of the floating diffusion voltage swing and pinning voltage typically limits the supply voltage for the active pixel sensor to a minimum of 2.5-3 Volts. However, there is a continuing demand for active pixel sensors with a supply voltage of less than 2.5-3 Volts as the demands for further miniaturization of active pixel sensors increase." So, the proposal is to reduce the FD swing by a capacitive feedback through Cfb 116:

Microsoft presents a augmented reality HoloLens headset mixing the real world with computer data, featuring in a Youtube video:



Another Youtube video shows Microsoft HoloLens demo driven by gesture control:



Engadget says "There are at least four cameras or sensors on the front of the HoloLens prototype." Mashable writes "Based on a quick look at the headset, it appears to have four front-facing cameras that could be used to detect the positions of the user's hands as she interacts with holographic objects."

Another Mashable article says "The augmented-reality headgear is full of sensors, but the most powerful one may be the 3D depth sensor. It’s the same one you’ll find in the Kinect and it is capable of building a detailed 3D mesh map of a room and everything in it. Once HoloLens knows what’s in the room, it can essentially drape 3D imagery over it so that it looks as if the digital objects and textures are part of the same environment as real world walls and furniture."

Microsoft HoloLens

Another Microsoft video briefly shows HoloLens internal design:

Wired reports that "the headset is still a prototype being developed under the codename Project Baraboo, or sometimes just “B.” Hololens chief inventor, Alex Kipman has "been working on this pair of holographic goggles for five years. No, even longer. Seven years, if you go back to the idea he first pitched to Microsoft, which became Kinect."

Seattle Times reports "The company isn’t saying how much a HoloLens will cost or when it will be broadly available but it’s likely to cost less than a high-end computer. Chief Executive Satya Nadella said it’s intended to be accessible to consumers as well as business users, though the latter seems to be a primary target."

Image Sensors London Conference

Image Sensor conference to be held on March 17-19, 2015 in London, UK, has published its final agenda:

Workshop – If you can’t make it global, then let the shutter roll!
Dr Albert Theuwissen, Founder, Harvest Imaging

This workshop will deal with needs, advantages, disadvantages and characteristics of several shutter that are being used with CMOS image sensors. Most devices on the market do have a rolling shutter, but there is a need to have a global shutter like it was the case for CCDs.

Fast moving objects in the scene do deform when read out in rolling shutter mode. But switching from a rolling shutter to a global shutter is not straight forward, for sure not in the case today's characteristics of the rolling shutter devices need to be maintained (correlated-double sampling, anti-blooming, electronic shuttering, low dark current). Two global shutter types are introduced in commercial products: storage of the signals in the charge domain or in the voltage domain.

The first part of the workshop will concentrate on the basic properties of the two shutter types, as well as on the effect the rolling and global shutter have on the imager characteristics. In the second part of the workshop two existing solutions, resp. of the global shutter in the charge domain as well as the global shutter in the voltage domain will be analyzed and compared with each other. Finally a look into the future will close the workshop.

Aptina Proposes In-Pixel Ramp for ADC

Image Sensors World        Go to the original article...

Aptina's patent application US20150009379 "Imagers with improved analog-to-digital circuitry" by Hai Yan and Kwang-bo Cho adds a capacitor on FD of the pixel to deliver ramp for the ADC:

"Conventional ramp circuitry applies the ramp voltage to a capacitor at the input of the comparator of the sample-and-hold circuitry. However, such an arrangement requires a high pixel supply voltage in order to support a wide range of pixel output signals sampled onto the capacitor (e.g., sufficient to support the well capacity of the pixel). The capacitor is required to have a capacitance sufficient to satisfy noise requirements such as a maximum amount of thermal (k*T/C) noise, which in turn requires the ramp circuitry to have high driving capability for driving the large capacitor. Conventional capacitors used in ramp circuitry can be hundreds of femtofarads (fF). The large sample-and-hold capacitor also occupies valuable circuit area of the imager. In addition, the pixel array is typically read by scanning pixel rows in sequential order. This sequential scanning can lead to row-dependent noise in the image output signals of the pixel array. For example, transient noise in a power supply signal is consistent throughout the pixels of a row but varies between rows. It would therefore be desirable to provide imagers with improved pixel readout and analog-to-digital conversion capabilities."

Aptina Proposes Discontinuous Exposure Mode

Image Sensors World        Go to the original article...

Aptina's patent application US20150009375 "Imaging systems with dynamic shutter operation" by Gennadiy Agranov, Sergey Velichko, and John Ladd presents the artifacts issue:

"In conventional imaging systems, image artifacts may be caused by moving objects, moving or shaking camera, flickering lighting, and objects with changing illumination in an image frame. Such artifacts may include, for example, missing parts of an object, edge color artifacts, and object distortion. Examples of objects with changing illumination include light-emitting diode (LED) traffic signs (which can flicker several hundred times per second) and LED stop lights of modern cars.

While electronic rolling shutter and global shutter modes produce images with different artifacts, the root cause for such artifacts is common for both modes of operation. Typically, image sensors acquire light asynchronously relative to the scenery being captured. This means that portions of an image frame may not be exposed for part of the frame duration. This is especially true for bright scenery when integration times are much shorter than the frame time used. Zones in an image frame that are not fully exposed to dynamic scenery may result in object distortion, ghosting effects, and color artifacts when the scenery includes moving or fast-changing objects. Similar effects may be observed when the camera is moving or shaking during image capture operations.
"

The proposed solution is:

"Each image pixel in a pixel array may include a shutter element for controlling when the photosensitive element acquires charge. For example, when a pixel's shutter element is “open,” photocurrent may accumulate on the photosensitive element. When a pixel's shutter element is “closed,” the photocurrent may be drained out from the pixel and discarded.

The shutter elements may be operated dynamically by being opened and closed multiple times throughout the duration of an imaging frame. Each cycle of dynamic shutter operation may include a period of time when the shutter is open and a period of time when the shutter is closed. At the end of each cycle, the charge that has been acquired on the photosensitive element during the cycle may be transferred from the photosensitive element to a pixel memory element. By repeating this sequence multiple times, the charge accumulated on the pixel memory element may represent the entire scenery being captured without significantly unexposed “blind” time spots.

Counter-Drones Need 12 Cameras for Interception

Image Sensors World        Go to the original article...

Popular Science: With all the privacy concerns associated with drone usage, Rapere.io offers a counter-drone. "Simply take it outside, put it on the ground, and press the GO button. The Rapere will take off, while at the same time scanning the sky for drones. It can tell the difference between a bird and a drone, and will fly over top of any drone within range, then disable it." Rapere strikes with string by lowering a tangle line onto the rotors of its target:


Twelve 90fps VGA cameras pointing in every direction are used to guide the drone to it's target - hovering above the free floating target drone. Rapere says that detecting a free floating object which is well illuminated and far from any other visible object is easy. The counter-drone can burn lots of watts on the onboard computer, because of the short intercept flight time, which also simplifies the work.

With drones and anti-drones both using many cameras, it appears that image sensor market is set for a new explosive growth.
