Abstract

The invention provides a high dynamic range (HDR) signal processing system and a high dynamic range signal processing method, wherein the method and the device support an HDR display device and a standard dynamic range (SDR) display device. In the HDR signal processing system, a front processing module receives a first linear HDR signal and converts the first linear HDR signal to a first SDR signal and a first mapping signal. An encoding module receives the first SDR signal and the first mapping signal and performs encoding of the first SDR signal and the first mapping signal for obtaining a bit flow, thereby facilitating signal transmission. A decoding module receives and performs decoding of the bit flow for obtaining the first SDR signal and the first mapping signal. A back processing module receives the first SDR signal and the first mapping signal which are decoded from the bit flow and performs reconstruction for obtaining a first linear HDR signal, wherein the first SDR signal can be displayed through the SDR display device, and furthermore the first linear HDR signal can be displayed through the HDR display device.

Description

technical field [0001] The present invention relates to a high dynamic range (High Dynamic Range; HDR) video signal processing system and method, in particular to a high dynamic range display device and a standard dynamic range (Standard Dynamic Range; SDR) display device with low computing power Complex high dynamic range signal processing system and method. Background technique [0002] In the past, traditional monitors mostly supported the display of standard dynamic range signals. However, with the development of technology, monitors that support high dynamic range signal display have begun to appear. For example, those that support the HDR signal format under the ITU BT.2020 specification The display device is currently a high dynamic range display device with an extremely wide display color gamut. Therefore, in the case of the coexistence of standard dynamic range and high dynamic range display specifications, it is often necessary to convert the input signal through ...
