Etron Technology Inc. has expanded its webcam controller IC product line with the release of two 3D webcam controllers. The eSP768 chip captures 3D images and video, while the eSP868 chip recognizes 3D motions and enables various gesture-controlled capabilities.

The eSP768 chip can simultaneously control both timing and image quality of two horizontally placed HD cameras to mimic the function of human eyes in capturing 3D images or video. It features a patented timing control mechanism to synchronize the left and the right images up to 30fps. In addition, it automatically aligns both left and right images in both x and y directions to compensate the unavoidable manufacturing discrepancies between two cameras on both sides. This minimizes both flickering and blurring noise effects that are commonly seen in previous 3D image/video capturing systems, noted Etron. With its flexible and programmable output image format, the eSP768 chip supports various kinds of 3D displays using Anaglyph, Shuttered, Polarized and Auto-stereoscopy (Lenticular and Parallax Barrier) technologies, added the company.


The controller ICs feature an image signal processor and USB 2.0.

The eSP868 chip provides all the features supported by the eSP768 and also generates a depth map from both left and right images, and therefore can have real 3D image recognition capabilities. As a result, the eSP868 chip can produce both 3D images and video while simultaneously enabling 3D motion recognitions of both gesture and body controls, claimed Etron. The eSP868 chip includes a special image signal processing engine that is used to optimize image qualities under various ambient conditions and to alleviate the well-known correspondence and divergence problems stemming from traditional stereo-vision cameras. It also provides user-friendly digital control function, continued the company. For example, a user can simply wave one's hand in front of home multimedia AV equipment to change displayed channels, adjust volume or switch viewing content.

The eSP868 can perform all 3D motion recognitions with commercially available sensors and therefore achieve a much lower system BOM cost, stated the company. With its fewer components, the eSP868 systems can be built into thin LCD panels and widely deployed into notebook, PC, TV and handheld devices.

Etron said the eSP768 and eSP868 chips are highly integrated SoC's with image signal processor, USB 2.0 interface with an image compression engine, four built-in LDO's, 40KB ROM, 6KB RAM, 8KB One Time Programming (OTP) memories and embedded CPU. Both chips support Windows, Mac, Linux and Android, and are available in either 64 LQFP (7 x 7mm) or 68 aQFN (6 x 6mm) packages.
