13. his non linear characteristic called gamma This would have significantly increased the cost of displays especially in the early days It was therefore decided to apply gamma to the video within the camera When this video is then played back on a CRT the result is a linier response Gamma has been applied to all video ever since Many new display technologies emerging today do not use phosphor to generate the image and therefore do not naturally display video correctly TFT panels such as those used in Vutrix displays do not have a gamma or a linear response It is therefore necessary to remove the gamma called reverse gamma and then apply a new correction specific to the panel type The result of this technology is to allow the display to simulate the response of a CRT in order to correctly reproduce the video as though it where being viewed on a CRT All Vutrix displays have a gamma control to allow the user to select the best gamma to match the source material Colour Temperature Colour temperature is an industry standard way to describe how white an image is compared with daylight This can be likened to viewing a piece of paper under candle light or under fluorescent lighting The paper is always the same colour but the ambient lighting in which it is viewed makes it appear different Colour temperature is a colour scale representing the colour of light emitted from a piece of platinum at specific temperatures in the Kelvin temp
