Embodiment Construction

[0040] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0041] The main ideas of the embodiments of the present invention are as follows: obtain standard dynamic range SDR data, and perform encoding and restoration processing on the SDR data to obtain the original linear data corresponding to the SDR data; Perform HDR conversion on the original linear data to obtain non-linear data; perform gamma preset adjustment on the non-linear data to obtain HDR data, and perform image display based on the HDR data.

[0042] refer to figure 1 , figure 1 It is a schematic diagram of the hardware structure of the image display terminal involved in the solution of the embodiment of the present invention.

[0043] The image display terminal in the embodiment of the present invention may be a smart TV, a smart phone, a tablet computer, a portable computer, and other terminal devices equi...

Abstract

The invention provides an image displaying method. The method comprises: acquiring standard-dynamic-range (SDR) data and performing encoding restoration processing on the SDR data to obtain original linear data corresponding to the SDR data; carrying out high-dynamic-range (HDR) transformation on the original linear data according peak brightness of an image display terminal to obtain non-linear data; and carrying out gamma presetting adjustment on the non-linear data to obtain HDR data and displaying a corresponding image based on the HDR data. In addition, the invention also provides an image display terminal and a computer readable storage medium. According to the invention, the original SDR content can be restored into the original linear data and then the original data are mapped again to obtain image data matching a target HDR display device, so that the SDR content is displayed at the HDR display device with the reasonable brightness; and the high dynamic characteristic of the HDR content is presented, so that the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image display method, a terminal and a computer-readable storage medium. Background technique [0002] Standard Dynamic Range SDR (Standard-Dynamic Range), originated from the era of CRT monitors, its standard brightness is 100cd / m 2 , the color space used is BT709 (HD) or BT601 (SD), quantized and encoded with BT1886 (gamma) 8bit. With the continuous development and upgrading of display technology, the current LCD, OLED and other new display devices have begun to adopt the high dynamic range HDR (High Dynamic Range) display technology, which adopts the BT2020 color space, greatly expanding the color gamut range, brightness Has far exceeded the CRT device. [0003] However, with 100cd / m as the benchmark, the SDR content collected and recorded by BT1886 can only be displayed on a low-brightness display of about 100cd / m such as a CRT, so that the original cont...
