Publisher description for Stuck Video Pixel Remover
As a professional video shooter you might never have heard about stuck, hot or Dead pixels. However a new kind of 'actors' are entering the video scene. With the release of the latest DSLR cameras such as the Canon 5D mk2 or the Nikon D90 the line between video cameras and photo cameras is fading. Capturing HD video will become a common feature on DSLR cameras and regarding video capabilities, DSLRs have 2 major assets. A huge set high quality lenses is available. In-lens stabilization and high optical quality used to be a solid base for ensuring outstanding pictures and Now they can be used to shoot high quality video too. A second asset of a Modern DSLR is its sensor. State of the art sensors ensure very low noise, high quality pictures in low light situations. The current DSLRs feature a first implementation of video (HD) capturing. A Photographer will call it a gadget... a video shooter will laugh it away. But one thing is for sure. DSLRs will change the the video scene fundamentally. Sounds promising... But... Of course there is a 'but'... Hot, Dead and Stuck Pixels - An important criteria in the DSLR competition is the sensor. In the very competitive digital camera market, the sensors in modern DSLRs are pushing technology to its limits in its strive to have more pixels with less noise. This result in outstanding performance but comes at a price of small defects during manufacturing. It is generally considered normal that some pixels out the the millions are defective. The defects come in 3 kinds. The pixel of the sensor captures the light by storing it as an electrical charge in a small capacitor. During the Exposure time it is possible that electrical charge for powering the sensor is leaking into the capacitor. During readout, this charge is read and interpreted as light, causing this pixel in the photo being lighter then it actually should be. This kind of defect is called hot pixel.
