Abstract:
To prevent gradation collapse. A BD player 1 includes a CPU 2 that obtains dynamic range of a monitor, a reproduction section 4 that obtains content information, and a video processor 5 that converts a digital video signal based on dynamic range of the monitor that is obtained by the CPU 2 and the content information that is obtained by the reproduction section 4. The video processor 5 converts each code value of the digital video signal of a content so that code value of the digital video signal that corresponds to “minimum luminance of the content” becomes code value that corresponds to “minimum luminance of the monitor” and code value of the digital video signal that corresponds to “maximum luminance of the content” becomes code value that corresponds to “maximum luminance of the monitor”.
