Description
本発明の映像記録装置は、標準ビデオよりも輝度範囲のダイナミックレンジが広い拡張ビデオのコンテンツを記録する映像記録装置であって、前記拡張ビデオのコンテンツの輝度分布を算出し、前記輝度分布から前記拡張ビデオのコンテンツの輝度頻度の高い輝度範囲を選択し、選択した前記輝度範囲を標準ビデオの輝度範囲に変換する輝度変換情報を作成する制御部と、前記拡張ビデオのコンテンツと前記輝度変換情報とを前記標準ビデオに対応した記録媒体に記録する記録部とを備えることを特徴とする。 Video recording apparatus of the present invention is a video recording apparatus that records the content of the dynamic range is wide extended video luminance range than standard video, to calculate the luminance distribution of the contents of the extended video, from the brightness distribution A control unit that selects a luminance range having a high luminance frequency of the extended video content and creates luminance conversion information for converting the selected luminance range into a standard video luminance range; and the extended video content and the luminance conversion information characterized in that it comprises a recording section for recording the bets on the recording medium corresponding to the standard video.
本発明の映像再生装置は、標準ビデオよりも輝度範囲のダイナミックレンジが広い拡張ビデオのコンテンツが記録された前記標準ビデオ対応の記録媒体を再生する映像再生装置であって、前記記録媒体に記録されているコンテンツの輝度分布情報を読み出す制御部と、前記記録媒体に記録されているコンテンツを再生する再生部と、前記拡張ビデオのコンテンツを標準ビデオのコンテンツに輝度変換する変換部とを備え、前記変換部は、前記輝度分布情報を用いて、前記拡張ビデオのコンテンツの輝度頻度の高い輝度範囲を選択し、選択した前記輝度範囲を前記標準ビデオの輝度範囲に変換する輝度変換式を作成し、前記輝度変換式を用いて前記選択した輝度範囲の輝度を前記標準ビデオの輝度範囲の輝度に変換することを特徴とする。 Video reproducing apparatus of the present invention, than standard video A video reproducing apparatus for reproducing the standard video-enabled recording medium in which the content of a wide dynamic range expanded video is recorded in the luminance range, recorded on the recording medium provided with a control unit for reading the luminance distribution information of the content is a reproducing unit that reproduces the content recorded on the recording medium, and a converter for the luminance conversion contents of the extended video content of a standard video, the The conversion unit uses the luminance distribution information to select a luminance range having a high luminance frequency of the content of the extended video, and creates a luminance conversion formula for converting the selected luminance range into the luminance range of the standard video, The luminance of the selected luminance range is converted into the luminance of the standard video luminance range using the luminance conversion formula .
