In a conventional camera lens, the iris consists of a set of overlapping mechanical blades that control the amount of light entering the camera. As efficient as this mechanical system is, it is too bulky and too difficult to miniaturize to be incorporated in smartphones and other compact devices. To address this, a team of researchers has used “smart glass” to create a micro-sized electronic iris that may bring much greater image quality and flexibility to smartphone cameras.

Nanoelectronics research center imec and XIMEA, a progressive creator of machine vision systems, today announced their partnership in integrating imec’s Hyperspectral Imaging (HSI) sensors together with XIMEA’s xiQ USB3.0 camera product line. Exceptional interoperability between camera and sensor’s technology streamlined the success of this integration.
“Combining imec’s hyperspectral sensor with XIMEA’s impressively compact xiQ cameras is a new milestone for us. The high-speed USB3.0 interface includes power supply over USB that removes the need for expensive and bulky frame-grabbers and separate power supplies. It will enable our partners to design and mass-produce extremely compact hyperspectral imaging camera solutions,” stated Andy Lambrechts, program manager for imaging & vision systems at imec.

The Cheap-Thermocam is a low-cost thermographic image scanner. With it you can analyse your house, electrical devices, etc. and identify for example thermal lacks.
Current FLIR cameras on the market cost a few thousand dollars.
My idea was to reduce costs by using one single non-contact temperature sensor to create a thermographic image.

Another quick project for today! How all started? A few hours ago I took a delivery box with few high resolution LCD’s on it. The box was made of foam material and was covered with dirty (from the delivery across two continents) yellowish tape.
To begin with, in order to open the box I had to remove half of this tape and by “playing” with the box I manage to remove everything without to damage it! Yes, the tape was strong enough to tear apart everything! The result is the one below

Heptagon Micro Optics Pte. Ltd. (Singapore) has announced that their 2 by 2 3D imaging system for use in smartphones, phablet and tablet computers is now ready for mass production. The TrueD H2 array camera is said to be the first in a series of 3D imaging and depth-sensing cameras that Heptagon will be introducing to the market.
Heptagon’s manufacturing processes enable the system aperture; stray light control and infrared cut filter to be integrated onto a single glass wafer. The assembly can withstand reflow temperatures and its no-focus lens eliminates the need to refocus after assembly. As well as grabbing the image the array camera captures short-range depth information that can be used for gesture and user recognition and allows background removal and image enhancement. Although this feature would typically be useful on a smart device’s front-facing camera, Heptagon state that it could also be used to complement the smart device’s primary high resolution image sensor. Applications include supporting 3D and immersive mobile video games as well as augmented reality overlays. [via]

The compact FPV system I have built is only about 20g, now even my mini quadcopter and micro hexacopter can carry this FPV camera and video transmitter. In this post I will share with you what are the parts you will need and how I made it.

Today I am going to talk about low cost and effective image processing for very specific embedded applications. I am not talking about robots recognizing their environment or finding their way to a power plug, but rather using small CMOS camera as better sensor. We have used this technology for various clients in our consulting service, so I am not going to get into the very specifics of any of those applications cause it would be a breach to our NDAs. Still, IKALOGIC aims to educate and share knowledge to the world. Considering that, I thought about writing a short tutorial, showing to beginners how to get started in that rather intimidating field.

This is the eagerly awaited 3.0 version of Photoduino. Photoduino is an open source camera controller based on the Arduino platform which you can use to automatically take pictures with your DSLR camera.
It serves as technical support for shooting high speed photos but you can also use it as an intervalometer to make Timelapse videos or for animals and insects photography.
Photoduino is an electronic circuit that is placed on an Arduino board as a Shield taking all the inputs, outputs and power pins. It has all the necessary electronic components and connectors for connecting the camera, flashes and sensors. You can control the shutter and camera autofocus, and you can also trigger two flashes. It also has a sound sensor, a shock/impact sensor and a laser or infrared barrier that can be used to take pictures when you register an event on any of the sensors. The configuration is done entirely through a small LCD screen using only two buttons, so it works independently without the need for a computer (except for firmware updates).
This system currently supports a wide range of DSLR cameras with a remote shutter cable connector.
Both hardware and firmware are completely open (like the Arduino platform on which it is based) and it is released under an open license.
