Abstract

Mevcut buluş, bır görüntünün bir derinlık haritasının çıkarılmasını, bahsedilen ekranın lokal olarak kontrol edilebilen her bir arka ışık bölgesi için bahsedilen derinlık haritasının bir histogrammın hesaplanmasını ve bahsedilen arka ışık bölgelerinin arka ışık sürüş değerlerinin bahsedilen hesaplanan histograma göre ayarlanmasını içeren, likit kristal ekranlar için bir lokal karartmanın açılması yöntemim anlatmaktadır Mevcut buluşun yöntemi ve sistemi kullanılarak lokal karartma kabiliyetine sahip ekranlar üzerinde doğru bir görüntü algısı elde edilebilir.The present invention provides a local for liquid crystal displays, comprising generating a depth map of an image, calculating a histogram of said depth map for each of the locally controllable backlight zones of said display, and adjusting the backlight driving values of said backlight zones relative to said calculated histogram. The method of the present invention provides an accurate image perception on screens with local dimming capability.
