HDR video enhancement, processing and coding
thesis
posted on 2015-11-26, 10:35 authored by Andrew LeonceAdvances in digital camera technology have led to the development of image sensors
that are capable of capturing High Dynamic Range (HDR) images. Although
this has enabled the capture of greater depths of colour and illumination, there remain
problems with regards to transmitting and displaying the HDR image data.
Current consumer level displays are designed to only show images with a depth
of 8-bits per pixel per channel. Typical HDR images can be 10-bits per pixel per
channel and upwards, leading to the first problem, how to display HDR images
on Standard Dynamic Range (SDR) displays. This is linked to a further problem,
that of transmitting the HDR data to the SDR devices, due to the fact that most
state-of-the-art image and video coding standards deal with only SDR data. Further,
as with most technologies of this kind, current HDR displays are extremely
expensive. Furthermore, media broadcast organisations have invested significant
sums of money into their current architecture and are unwilling to completely
change their systems at further cost. [Continues.]
