Yet another pixel post-processing acquisition

Sigma Designs acquires Gennum, ST acquires Genesis, Zoran acquires Let It Wave and now IDT acquires Silicon Optix. Silicon Optix was another company that focused on developing the highest quality video format converters. This acquisition is a bit different from the others since IDT doesn’t have any digital media application processors for set top boxes or Blu-ray players that need integrated post-processing functionality. Instead, IDT is likely to get synergy out of this acquisition by combining the post-processing products with their mixed signal consumer video products.

Parallel painty pixels

Every engineer loves Adam and Jamie from the Mythbusters, and now we video engineering guys have a reason to love them even more. Here’s a clip showing a display Adam and Jamie built that uses 1100 paintball guns to draw a reproduction of Leonardo’s Mona Lisa with a refresh rate of 80ms. They only refresh once, though.

Audio-focused pixels

Liquid lenses have been around for some time. Varioptic applies a voltage to a lens made of water and oil to change the optical properties and achieve focus or zoom. The Rensselaer Polytechnic Institute created a new optical system using a liquid lens and a small speaker. Instead of applying a voltage, they apply sound to move the water droplets to achieve a focusing effect.

Varioptic hasn’t really made an impact on the camera module market yet. Will Rensselaer’s technique finally bring liquid lenses into mass production?
