Watch out for dead pixels


A dead pixel in a camera imaging sensor can manifest itself in a number of ways. Implying black, 'dead' is not necessarily the correct term for a pixel failure. This is because imager defects include hot pixels, sparkles, noisy or lazy pixels. These problems usually arise during the chip manufacturing process. Defective pixels can appear as unusual...

3D Five years on


For me, IBC2006 was the beginning of the modern 3D era. At an invitation-only presentation, 3ality’s CEO Steve Schklair described what his company was achieving with S3D. Suddenly it all made sense. With the accuracy of digital shoots and computer technology replacing difficulties and expense of working with film, 3D could now be viable. Unlike the...

Eye to Eye: Video Post-production


My first direct experience of video post-production involved hauling a heavy Sony U-Matic tape machine up a flight of stairs before going back for an equally heavy playback deck, a bulky CRT monitor and a large box of interface giblets. That was in 1978. 33 years on, an Apple Mac does the whole editing job a great deal better, faster and more econo...

True Colours Shine Through With CCS


When you are a broadcast engineer working in front of a stack of LCD monitors, seeing a significant difference between the brightness and colour of each monitor can be both annoying and tiring on the eyes. Worse still, if you in a Master Control Room and the pictures have taken on a sickly green hue, how do you know that it is just the monitors at...

This can have a detrimental effect on a company’s reputation and profits, and could even have legal implications. The best w...
