An imaging device includes a display unit for displaying an image, an imaging optical system, an imaging unit, a posture detector for detecting a posture of the imaging device in shooting, a recording unit for recording a reduced image of a shot image, and posture information on a posture of the imaging device corresponding to the reduced image, an image extracting unit for extracting reduced images including the same posture information among said reduced images recorded on the recording unit, and an image display controller for displaying the reduced images extracted by the image extracting unit on the display unit, wherein the image display controller reconstructs, on the basis of the posture information, a horizontal and vertical direction of the reduced images extracted by the image extracting unit to the posture of the imaging device in shooting, and displays the reduced image being reconstructed on the display unit. Thereby, that makes it possible to display a comfortable reduced image.
