TONE MAPPING METHOD AND APPARATUS - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18336837 Titled 'TONE MAPPING METHOD AND APPARATUS'
Simplified Explanation
This abstract describes a method and device for tone mapping, which involves adjusting the contrast and brightness of a high dynamic range (HDR) image. The backend device receives metadata and the HDR image from a frontend device. The backend device then generates a mapping curve based on feature parameters included in the metadata. The mapping curve is used to perform tone mapping on the HDR image. The frontend device determines the feature parameters of the mapping curve based on the luminance distribution status of the HDR image. This allows for more flexibility in designing the mapping curve and effectively improving the display effect of the HDR image.
Original Abstract Submitted
Tone mapping methods and apparatus provide for receipt by a backend device may of metadata and an HDR image from a frontend device and the generation of a mapping curve based on feature parameters of the mapping curve included in the metadata. Tone mapping on the HDR image can be performed based on the mapping curve. The feature parameters of the mapping curve are determined by the frontend device based on a luminance distribution status of the HDR image. In this way, the mapping curve parameters are determined based on the luminance distribution status of the HDR image so that design of the mapping curve is more flexible, and display effect of the HDR image can be effectively improved.
