An imaging apparatus comprising: an imaging unit that images a subject; a display unit that subjects an image captured by the imaging unit to live view display, whereby a plurality of first images captured by the imaging unit are displayed in succession according to the frame rate of the imaging unit, and whereby a target mark is displayed in a superimposed manner during the live view display for designating a designated area, the target mark comprising a pair of right and left brackets or a rectangular grid-line; an image acquisition unit configured to: (i) receive a tap operation as a designation operation of extraction of a composition target as a result of the periphery of the target mark being tapped with a finger of the user, and (ii) acquire a selected first image as an image displayed on the display unit, the selected first image being subject to the live view display at the time of the tap operation; an extraction unit configured to extract a part of the selected first image as the composition target for image composition, wherein the extraction unit (i) determines an area designated by the tap operation as an extraction area for extracting the composition target in the selected first image to be the designated area, and (ii) extracts the composition target from the designated area by determining a boundary portion with large contrast to be the contour of the composition target to be extracted based on contrast of pixels in the designated area; a composition unit that composes the composition target to a second image captured by the imaging unit and different from the first image; and a display control unit that performs control such that the second image, to which the composition target is composed, is subjected to live view display on the display unit. an imaging unit that images a subject; a display unit that subjects an image captured by the imaging unit to live view display, whereby a plurality of first images captured by the imaging unit are displayed in succession according to the frame rate of the imaging unit, and whereby a target mark is displayed in a superimposed manner during the live view display for designating a designated area, the target mark comprising a pair of right and left brackets or a rectangular grid-line; an image acquisition unit configured to: (i) receive a tap operation as a designation operation of extraction of a composition target as a result of the periphery of the target mark being tapped with a finger of the user, and (ii) acquire a selected first image as an image displayed on the display unit, the selected first image being subject to the live view display at the time of the tap operation; (i) receive a tap operation as a designation operation of extraction of a composition target as a result of the periphery of the target mark being tapped with a finger of the user, and (ii) acquire a selected first image as an image displayed on the display unit, the selected first image being subject to the live view display at the time of the tap operation; an extraction unit configured to extract a part of the selected first image as the composition target for image composition, wherein the extraction unit (i) determines an area designated by the tap operation as an extraction area for extracting the composition target in the selected first image to be the designated area, and (ii) extracts the composition target from the designated area by determining a boundary portion with large contrast to be the contour of the composition target to be extracted based on contrast of pixels in the designated area; (i) determines an area designated by the tap operation as an extraction area for extracting the composition target in the selected first image to be the designated area, and (ii) extracts the composition target from the designated area by determining a boundary portion with large contrast to be the contour of the composition target to be extracted based on contrast of pixels in the designated area; a composition unit that composes the composition target to a second image captured by the imaging unit and different from the first image; and a display control unit that performs control such that the second image, to which the composition target is composed, is subjected to live view display on the display unit.
