Abstract
An information processing device performs a first setting relating to an opto-electronic transfer function (OETF), performs a second setting relating to an electro-optical transfer function (EOTF), generates a developed image by applying development processing to a RAW image according to the first setting, and performs control to record the developed image on a storage medium. In a case when the first setting is a setting corresponding to a high dynamic range and the second setting is a setting corresponding to a dynamic range different from the high dynamic range, control is performed to record the developed image and meta information corresponding to the second setting on the storage medium in association with each other.
Claims19
An information processing device comprising:
- at least one memory and at least one processor that function as a plurality of units comprising:
- (1) a first setting unit configured to set an opto-electronic transfer function (OETF);
- (2) a second setting unit configured to set an electro-optical transfer function (EOTF);
- (3) a development unit configured to generate a developed image by applying development processing to a RAW image according to the set OETF;
- and
- (4) a recording control unit configured to perform control to record the developed image in a storage medium,
- wherein in a case where (a) the set OETF corresponds to a high dynamic range and (b) the set EOTF corresponds to a dynamic range different from the high dynamic range, the recording control unit performs control to record the developed image and meta information in the storage medium in association with each other, and
- wherein the meta information comprises information regarding a color gamut corresponding to the set EOTF.
An information processing device comprising:
- at least one memory and at least one processor that function as a plurality of units comprising:
- (1) a first setting unit configured to set an opto-electronic transfer function (OETF);
- (2) a second setting unit configured to set an electro-optical transfer function (EOTF);
- (3) a development unit configured to generate a developed image by applying development processing to a RAW image according to the set OETF;
- and
- (4) a display control unit configured to perform control to display the developed image on a display,
- wherein, in a case where (a) the set OETF corresponds to a high dynamic range and (b) the set EOTF corresponds to a dynamic range different from the high dynamic range, the display control unit performs control to display the developed image on the display without performing gradation conversion.
