Imaging apparatus, method and program

An imaging apparatus, comprising:

• an imaging unit which picks up an object;
• a setting unit which sets a synthesis imaging mode;
• an imaging control unit which controls imaging in the imaging unit according to the setting unit setting the synthesis imaging mode;
• a storing unit which stores a plurality of image data picked up by the imaging unit;
• an image synthesizing unit which subjects the plurality of image data stored in the storing unit to an image synthesizing process so that duplicated areas between images are superimposed;
• a specifying unit which specifies a desired area based on input operation;
• a display area setting unit which sets a display area in the synthesized image obtained from the image synthesizing process by the image synthesizing unit based on the area specified by the specifying unit;
• a display unit which displays the display area set by the display area setting unit;
• a recording area setting unit which sets a recording area based on the display area displayed on the display unit;
• and
• a recording unit which records image data in the recording area set by the recording area setting unit, wherein
• the display area setting unit includes:
• a temporary display area setting unit which sets a temporary display area;
• a temporary setting control unit which controls the temporary display area setting unit to minimize V, where an area of a first area where the synthesized image exists outside the temporary display area set by the temporary display area setting unit is taken as S1, an area of a second area where the synthesized image does not exist inside the temporary display area is taken as S2, a W1 and W2 are taken as a predetermined weighting constant and V=W1×S1+W2×S2;
• a regular setting unit which sets a temporary display area in which the V is minimized to the display area;
• and
• a coloration unit which colors a predetermined color to part where the synthesized image does not exist in the display area set by the regular setting unit.
