Image-capturing device, proposal-image generating device, proposal-image generating method, proposal-image generating program, and storage medium

A proposal-image generating device comprising:

• a subject-extracting unit that separates and extracts a main subject and a background from an image acquired by an image-capturing unit;
• a distance-information acquiring unit that calculates a distance between the image-capturing unit and the main subject extracted by the subject-extracting unit and a distance between the image-capturing unit and the background extracted by the subject-extracting unit;
• a photographing-condition acquiring unit that acquires acquisition-time photographing conditions for an acquisition time of the image and an adjustable photographing condition that can be adjusted with respect to the acquisition-time photographing conditions;
• a photographing-condition selecting unit that selects a photographing condition that is worth adjusting on the basis of the acquisition-time photographing conditions and the adjustable photographing condition acquired by the photographing-condition acquiring unit and the distances acquired by the distance-information acquiring unit;
• and
• an image-processing unit that generates, by performing image processing on the image acquired by the image-capturing unit, an image that will be acquired when the photographing condition selected by the photographing-condition selecting unit is set.

A proposal-image generating method comprising:

• a subject-extracting step of separating and extracting a main subject and a background from an image acquired by an image-capturing unit;
• a distance-information acquiring step of calculating a distance between the image-capturing unit and the main subject extracted in the subject-extracting step and a distance between the image-capturing unit and the background extracted in the subject-extracting step;
• a photographing-condition acquiring step of acquiring acquisition-time photographing conditions for an acquisition time of the image and an adjustable photographing condition that can be adjusted with respect to the acquisition-time photographing conditions;
• a photographing-condition selecting step of selecting a photographing condition that is worth adjusting on the basis of the acquisition-time photographing conditions and the adjustable photographing condition acquired in the photographing-condition acquiring step and the distances acquired in the distance-information acquiring step;
• and
• an image-processing step of generating, by performing image processing on the image acquired by the image-capturing unit, an image that will be acquired when the photographing condition selected in the photographing-condition selecting step is set.

A non-temporary computer-readable storage medium that stores a proposal-image generating program that causes a computer to execute:

• a subject-extracting step of separating and extracting a main subject and a background from an image acquired by an image-capturing unit;
• a distance-information acquiring step of calculating a distance between the image-capturing unit and the main subject extracted in the subject-extracting step and a distance between the image-capturing unit and the background extracted in the subject-extracting step;
• a photographing-condition acquiring step of acquiring acquisition-time photographing conditions for an acquisition time of the image and an adjustable photographing condition that can be adjusted with respect to the acquisition-time photographing conditions;
• a photographing-condition selecting step of selecting a photographing condition that is worth adjusting on the basis of the acquisition-time photographing conditions and the adjustable photographing condition acquired in the photographing-condition acquiring step and the distances acquired in the distance-information acquiring step;
• and
• an image-processing step of generating, by performing image processing on the image acquired by the image-capturing unit, an image that will be acquired when the photographing condition selected in the photographing-condition selecting step is set.
