Truesense Acquisition Story

Rochester Business Journal publishes a story on Truesense acquisition by ON Semi. Few quotes:

"Eight prospective buyers emerged to purchase Truesense, touring the company’s facilities and evaluating its online data box, said Christopher McNiffe, previous CEO of Truesense Imaging and current vice president of the image sensor business unit of ON Semiconductor... Roughly 300 people now report to McNiffe, including 50 people who work near Brussels, Belgium, a dozen in Bangalore, India, and 10 in Santa Clara, Calif."

"Under ON Semiconductor’s watch, Truesense Imaging is expected to grow, officials say."

"I see the real power of this acquisition being we have the best of both worlds," McNiffe said. "So now we can go in to a customer and we can say: ‘Here’s a broad portfolio of high-performance image sensors. Which one of these is the best fit for what you’re trying to do?’ That’s something that no one else in our industry is able to do right now."

TowerJazz and Genoray Announce 100um Pixel X-Ray Sensor

Business Wire: TowerJazz and Genoray announces a successful development of a CIS for medical diagnostic devices such as X-ray equipment, fluoroscopy and radiography in TowerJazz’s 0.18um CIS stitch process. The novel device which has a 100um pixel size and has a special feature to control the sensitivity of the pixel which can be applied in various types of medical equipment such as surgical C-Arms and portable X-ray machines.

This new device is a CIS detector whereas the existing market uses a silicon TFT type sensor. The advantage of CIS compared to TFT is that CIS uses active pixels so it obtains the image with less noise and helps minimize X-ray radiation exposure which is currently the biggest issue in the industry. Furthermore, Genoray’s single detector supports both CT mode and Panorama mode while the existing products in the market only support one by one (CT supports only CT mode, Panorama supports Panorama mode only). This means that by providing multi-functions through one detector, Genoray can satisfy customers who need both modes with a less expensive price point; a competitive advantage of this product.

LinX Imaging Announces Array Camera for Mobile Applications

Business Wire: "The image quality of mobile cameras has reached a dead end. Device makers are striving to differentiate using imaging capabilities but the pixel size race has ended and next generation cameras do not reveal any dramatic improvements," says LinX Computational Imaging Ltd.. The company reports that it has successfully developed miniature multi-aperture cameras for mobile devices with nearly half the height of a standard mobile camera and are capable of creating stunning color images and high accuracy depth maps. The engineers at LinX have solved all problems associated with combining multiple images captured from different points in space such as registration errors and occlusion related artifacts which are seen on competing technologies, so that LinX cameras are artifact-free, even when objects appear at very short range.

LinX software also creates a true depth information on high contrast objects and on near flat surfaces, such as walls, which are traditionally considered difficult for passive stereo systems. With its partners, LinX has developed a variety of products ranging from arrays of two, three, and four cameras in various configurations and sizes, some with autofocus and others without. The technology is said to be ready for integration into the current generation mobile devices:


LinX technology is said to have many advantages over traditional mobile photography:

  • A larger sensor requires a longer lens. Therefore, by replacing one large sensor with two or more smaller ones, we reduced the height of our device by a factor of 1.4 to 2
  • Sensitivity to light increases by a factor of 3 by using a monochrome sensor
  • Noise levels are dramatically lower
  • The effective array camera resolution is similar to the single aperture camera in high light
  • Performance and image quality in low light are extraordinary
  • Allowing a fast exposure at indoor standard lighting conditions of 100-200 lux which assures crisp images free from motion blur
  • The multi-aperture camera creates a real-time, high-quality distance map

30-page LinX technology presentation shows many comparison pictures with iPhone 5s and Galaxy s4 cameras, many of them in low light:

Apple Applies for Li-Fi-Optimized Image Sensor Patent

Apple patent application US20140125852 "Optical demodulation using an image sensor" by Richard Baer, Michael Malone, Ting Chen, and David Amnon Silverstein proposes two-mode image sensor. The first mode is a regular image capture, while the second one is optimized for the lighting LED-based data communication (Li-Fi). In Li-Fi mode, "the integration interval for the image sensor is set to less than two row periods, preferably close to one row period, without regard to the exposure data if the data capture mode is selected.

An analog gain may be increased to as large a value as possible in data capture mode. All pixels in a row may be summed before analog to digital conversion in data capture mode. An image sensor frame period may be set according to a signaling frame period of an illumination modulation data transmission in data capture mode.

The controller may further causes data to be inverted from frame to frame and decoding of the difference of two successive frames if the data capture mode is selected. The controller may further causes defocusing of an optical system that forms an image on the image sensor if the data capture mode is selected.
