The advanced contrast enhancer brings out the details in your videos and pictures
In Mobile BRAVIA® Engine 2, the contrast enhancement algorithm has been updated compared to the previous version, to optimise the contrast of every scene by analysing the distribution of luminance in each frame. It reproduces true blacks while faithfully recreating all the subtle gradations. This will give your images and videos more dynamics and better perceived details, which make the scenes come alive.
