Patent ID: 10791299

Abstract:
Disclosed is a method for converting an HDR image into an SDR image. The method includes the following operations: acquiring, by a television terminal, input HDR image data, and processing, by the television terminal, the acquired HDR image data through a first normalization; linearizing, by the television terminal, the HDR image data processed through the first normalization; processing, by the television terminal, the linearized HDR image data through a second normalization; and converting, by the television terminal, the HDR image data processed through the second normalization into SDR image data with a supported format. The present disclosure further provides a television terminal and a computer readable storage medium. The present disclosure effectively avoids the technical problem of a poor image display effect caused by that the non-HDR receivers cannot show the HDR effect. The present disclosure enables non-HDR receivers to show the HDR effect and improves the image display effect.
