During the last 50 years miniaturization became a key element in human history, since it opens doors for manufacturing new devices that enhances the quality of human life. Camera and imaging systems are following this miniaturization trend as well. Meanwhi ...

In thiswork,we present aminiaturized high definition vision system inspired by insect eyes, with a distributed illumination method, which can work in dark environments for proximity imaging applications such as endoscopy. Our approach is based on modeling ...

Inspiration from light field imaging concepts has led to the construction of multi-aperture imaging systems. Using multiple cameras as individual apertures is a topic of high relevance in the light field imaging domain. The need for wide field-of-view (FOV ...

High dynamic range (HDR) images are usually obtained by capturing several images of the scene at different exposures. Previous HDR video techniques adopted the same principle by stacking HDR frames in time domain. We designed a new multi-camera platform wh ...

A multi-camera hemispherical very wide field of view imaging apparatus with omnidirectional illumination capability comprises a cylindrical body (4, 4.a, 4.b), a hemispherical mechanical frame (2) arranged on one end of the cylindrical body (4, 4.a, 4.b), ...

PowerPC Architecture microcontrollers are commonly used in embedded applications. In this work we present FireBird, the first PowerPC based SoC for reliable operation beyond 200C. It is a significant challenge to design SoCs for reliable operation at high ...
