Abstract

In this playback method for playing back an image stream, the image stream is configured with a first dynamic range in which the maximum value of brightness in a dynamic range exceeds 100 nits, and a display device displays an image in a second dynamic range narrower than the first dynamic range. The playback method comprises: determining whether the image stream is quantized on the basis of a hybrid OETF; playing back the image stream without performing brightness transform, which transforms the brightness of the image stream from the first dynamic range to the second dynamic range, when the image stream is determined to be quantized on the basis of the hybrid OETF; and performing the brightness transform on the image stream and playing back the image stream, when the image stream is determined not to be quantized on the basis of the hybrid OETF.
