An excerpt of it is reprinted here with the permission of Digi-Key. Embedded vision, the evolution and extrapolation of computer-based vision systems that process and interpret meaning from still and video images, is poised to be […]
In the introductory essay to last Thursday's Embedded Vision Insights newsletter, and in speaking of Nokia's new cameraphone, I wrote: The Nokia 808 contains a 41 Mpixel image sensor (no, that's not a typo), notable not only for its high resolution but also for its relatively relaxed 1.4 um pixel pitch, the latter translating into

Kudos to EDN Magazine's Margery Conner for "tweeting" me a heads-up about a Samsung announcement at the recent ISSCC (International Solid State Circuits Conference), originally covered by Nikkei Business Publications' Tech-On! and later also picked up by Gizmodo, The Verge and TechCrunch. At first glance, the image sensor above may look like a convention Bayer-patterned

Brian Dipert, Editor-In-Chief of the Embedded Vision Alliance, interviews Gene Frantz, Texas Instruments Principal Fellow. Gene, who has been with the company for nearly 40 years, did his early work with DSPs in association with the Speak & Spell speech synthesizer. In this two-part series, Gene and Brian discuss the history of the DSP both

by Dong-Ik Ko and Gaurav Agarwal Texas Instruments This article was originally published in the December 2011 issue of Embedded Systems Programming. Gesture recognition is the first step to fully 3D interaction with computing devices. The authors outline the challenges and techniques to overcome them in embedded systems. As touchscreen technologies become more pervasive, users

As I previously mentioned in a technical article published to the Embedded Vision Alliance site last August, the Bayer Pattern (named after Eastman Kodak's Bryce E. Bayer, its inventor) is by far the most common filter array pattern used with both CCDs and CMOS image sensors. Containing 50% green filters, 25% red filters and 25%

By Brian Dipert Editor-In-Chief Embedded Vision Alliance Senior Analyst BDTI A diversity of image sensor options are available for your consideration, differentiated both in terms of their fundamental semiconductor process foundations and of their circuit (and filter, microlens and other supplement) implementations. Understanding their respective strengths and shortcomings is critical to making an appropriate product
