Abstract
A video processing method includes: obtaining a first video signal; detecting, in a region of a first video represented by the first video signal obtained, a first region including a graphic different from a main video; calculating a first peak luminance of a second region that is the region of the first video excluding the first region; performing a tone mapping process on the first video, the tone mapping process decreasing a luminance higher than the first peak luminance; and outputting a second video signal representing a second video after the tone mapping process.
Claims7
A video processing method comprising:
- obtaining a first video signal;
- detecting, in a region of a first video represented by the first video signal obtained, a first region including a graphic different from a main video;
- calculating a first peak luminance of a second region that is the region of the first video excluding the first region;
- performing a tone mapping process on the first video, the tone mapping process decreasing a luminance higher than the first peak luminance;
- and
- outputting a second video signal representing a second video after the tone mapping process,
- wherein the first video is a moving picture including frames, and
- the detecting of the first region, the calculating of the first peak luminance, and the tone mapping process are performed for each of the frames.
A video processing device comprising:
- an obtainer that obtains a first video signal;
- a detector that detects, in a region of a first video represented by the first video signal obtained, a first region including a graphic different from a main video;
- a calculator that calculates a first peak luminance of a second region that is the region of the first video excluding the first region;
- a tone mapping processor that performs a tone mapping process on the first video, the tone mapping process decreasing a luminance higher than the first peak luminance;
- and
- an outputter that outputs a second video signal representing a second video after the tone mapping process,
- wherein the first video is a moving picture including frames, and
- the detecting of the first region, the calculating of the first peak luminance, and the tone mapping process are performed for each of the frames.
