Abstract:
1. A converting apparatus comprising: a first convertor that converts a first image signal whose luminance range is a first luminance range into a second image signal whose luminance range is a second luminance range, wherein the second luminance range is larger than the first luminance range; an encoder that encodes the second image signal to generate an encoded image signal; a recorder that records the encoded image signal on a recording medium, and records information indicating the second luminance range on the recording medium; a reproducing unit that reproduces the encoded image signal from the recoding medium, and reproduces the information from the recoding medium; a decoder that decodes the encoded image signal to generate a third image signal whose luminance range is the second luminance range; and a second convertor that converts the third image signal whose luminance range is the second luminance range into a fourth image signal whose luminance range is a third luminance range, wherein the third luminance range is smaller than the second luminance range.
