Image processing device, imaging apparatus, image processing method, and program for determining a condition for high dynamic range processing

An image processing device comprising:

• a processor configured to:
• acquire information about an in-focus position of a captured image set by a photographer;
• acquire first distance information which is distance information of a plurality of areas in the captured image;
• calculate, on the basis of the information about the in-focus position and the first distance information of the plurality of areas, for each of the plurality of areas, second distance information which is information indicating a distance from the in-focus position;
• determine, on the basis of the second distance information, for each of the plurality of areas, a representative luminance calculation area in which a shooting intention of the photographer is reflected for acquiring luminance information that is to be used to calculate a representative luminance that is to be used in high dynamic range processing,
• wherein the processor compares the second distance information with a depth of field and determines that the representative luminance calculation area is the area which has the second distance information within the depth of field;
• calculate the representative luminance in which the shooting intention of the photographer is reflected on the basis of luminance information of the representative luminance calculation area;
• and
• determine a second condition of the high dynamic range processing on the basis of the representative luminance that is calculated.
