University of Toronto student tech shoots HDR video in real-time (eyes-on)

Positive, you’re keen on the HDR footage coming out of your level-and-shoot, smartphone or maybe even your Glass. However what if you wish to Hangout in HDR? An enterprising grad scholar from the College of Toronto named Tao Ai — beneath the tutelage of Steve Mann — has found out methods to shoot HDR video in actual-time. The trick was completed utilizing a Canon 60D DSLR operating Magic Lantern firmware and an off-the-shelf video processing board with a subject programmable gate array (FPGA), plus some customized software program to course of the video coming from the digital camera. It really works by taking in a uncooked feed of alternatively underneath and over uncovered video and storing it in a buffer, then processing the video on its approach to a display. What outcomes is the nearly latency-free 480p decision HDR video at 60 frames per second seen in our video after the break.

Once we requested whether or not larger decision and quicker body fee output is feasible, we have been advised that the present limitations are the velocity of the imaging chip on the board and the bandwidth of the reminiscence buffer. The setup we noticed utilized a comparatively low cost $200 Digilent board with a Xilinx chip, however a 1080p model is within the works utilizing a costlier board and DDR3 reminiscence. In fact, the present system is for analysis functions solely, however the know-how might be utilized in shopper units — so long as they’ve an FPGA and supply open supply firmware. So, ought to the OEM’s get with this system, we will have HDR shifting footage to go together with our stationary ones.
