Reproduction method, creation method, reproduction device, creation device, and recording medium

A generating method comprising:

• an obtaining step of obtaining RAW data;
• a first generating step of generating a high quality image that is a still image from the RAW data;
• a second generating step of generating from the RAW data a first low quality image showing a scene identical to a scene shown by the high quality image;
• and
• an outputting step of outputting the high quality image, the first low quality image, and conversion determination information used by a reproduction device to determine whether the reproduction device (1) reproduces the first low quality image or (2) generates a second low quality image from the high quality image and reproduces the second low quality image when a display device connected to the reproduction device cannot display the high quality image.

A reproduction device that reproduces an image and outputs the reproduced image to a display device, the reproduction device comprising:

• an obtaining device that obtains a high quality image and a first low quality image that are still images showing an identical scene, and conversion determination information;
• a determining device that determines whether or not the display device can display the high quality image, and determines whether or not to generate a second low quality image by using the conversion determination information when the display device cannot display the high quality image;
• and
• a reproducer that (1) reproduces the high quality image when the display device can display the high quality image, (2) reproduces the first low quality image when the determining unit determines not to generate the second low quality image, and (3) generates the second low quality image from the high quality image and reproduces the second low quality image when the determining unit determines to generate the second low quality image.

A generating device comprising:

• an obtaining device that obtains RAW data;
• a first generator that generates a high quality image that is a still image from the RAW data;
• a second generator that generates from the RAW data a first low quality image showing a scene identical to a scene shown by the high quality image;
• and
• an output device that outputs the high quality image, the first low quality image, and conversion determination information used by a reproduction device to determine whether the reproduction device (1) reproduces the first low quality image or (2) generates a second low quality image from the high quality image and reproduces the second low quality image when a display device connected to the reproduction device cannot display the high quality image.

A recording medium having recorded thereon:

• a high quality image that is a still image;
• a first low quality image that shows a scene identical to a scene shown by the high quality image;
• and
• conversion determination information that is used by a reproduction device to determine whether the reproduction device (1) reproduces the first low quality image or (2) generates a second low quality image from the high quality image and reproduces the second low quality image when a display device connected to the reproduction device cannot display the high quality image.
