Abstract: An adjusting device includes an acquisition unit that acquires a non-linear first video signal generated using a first opto-electronic transfer function (OETF), a converter that performs conversion processing of converting the first video signal acquired by the acquisition unit into a non-linear second video signal obtained (i) by converting the first video signal into a linear signal using an inverse characteristic of the first OETF, (ii) by performing adjusting processing including a gain change in which a relationship between an input value and an output value becomes linear on the linear signal, and (iii) by converting a post-adjustment linear signal obtained by performing the adjusting processing using a second OETF corresponding to a predetermined format, and an output unit that outputs the second video signal obtained by a conversion performed by the converter.

Abstract: An editing method includes: obtaining a high quality image and a first low quality image that are still images showing an identical scene, and edit management information that indicates whether or not to permit editing at least one image of the high quality image and the first low quality image; and editing the at least one image when the edit management information indicates to permit editing the at least one image, and when the edit management information indicates not to permit editing the at least one image, the at least one image is not edited.

Abstract: A reproducing method includes: an obtaining step of obtaining a high quality image and a first low quality image that are still images showing an identical scene, and conversion determination information; a first determining step of determining whether or not the display device can display the high quality image; a first reproducing step of reproducing the high quality image when the display device can display the high quality image; a second determining step of determining 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; a second reproducing step of reproducing the first low quality image when it is determined not to generate the second low quality image; and a third reproducing step of generating the second low quality image from the high quality image and reproducing the second low quality image when it is determined to generate the second low quality image.
