There are two options for this, I think in one it applies a different gamma correction ( the raw pictures are 16 bit, so there is plenty of room to increase the dynamic range ).

Other technologies incorporated in the EMP-7300 projector are polarisarion conversion for more uniform brightness, panel on prism for sharper images and real-time image resizing for accurate data compression and digital gamma correction for better colour gradation.

Strictly speaking, the curves tool usually does more than simple gamma correction, since one can construct complex curves with multiple inflection points, but when no dedicated gamma correction tool is provided, it can achieve the same effect.
44.
Furthermore, images displayed on 24-bit RGB hardware ( 8 bits per RGB primary ) can be dithered to simulate somewhat higher bit depth, and / or to minimize the loss of hues available after a gamma correction.
45.
Furthermore, traditional images are usually encoded for the human visual system ( maximizing the visual information stored in the fixed number of bits ), which is usually called " gamma encoding " or " gamma correction ".

As of 2007, analog inputs were more commonly used than digital, but this changed as flat panel displays with RAM ), which contains conversion tables for gamma correction, contrast and brightness, to make a device called a RAMDAC.
48.
The reason for this high quality processing is : provide proper realistic up and down sampling of images, and photorealistic display regardless of the monitor gamma, without colour fringing caused by 8-bit gamma correction built into the X server.
49.
It is better to apply the gamma correction with the display hardware ( most modern display adapters support this feature ), or as an active intermediate step of the rendering software through color management, which preserves the original color values.
50.
With gamma correction, rather than adjusting the brightness of a scan by changing all the light and dark pixels in the same way, light and dark pixels can be adjusted differently to improve the balance and contrast of the image.
