An image generating device comprising: an acquisition means (S220, S225) for capturing an image of an imaging region around an own vehicle with a camera through a wide-angle lens, and acquiring image data, the imaging region being configured by a plurality of imaging areas (111 to 113); a determination means (S200 to S215) for detecting an object present around the own vehicle and determining whether the object is present in the imaging areas, on the basis of detection results; a selection means (S220, S225) for selecting a target area to be displayed in an easy-to-see state from among the plurality of imaging areas, on the basis of determination results derived from the determination means; a generation means (S220, S225) for adjusting a reduction degree of an image of at least one imaging area in the plurality of imaging areas such that the image of the target area is displayed in an easy-to-see state compared to the image of at least one remaining imaging area, and correcting the image data to generate display image data for displaying the entire imaging region; and a display means (S220, S225) for displaying the display image data, characterized in that: the imaging region horizontally extends around the own vehicle, the imaging areas are arranged in a row in a horizontal direction intersecting a forward direction of the camera and include a center area and right and left areas (111, 113), when the determining means determines that the object is not present in any of the imaging areas, the selection means is configured to select the right and left areas as imaging areas that are difficult for a driver to directly see during driving and determines such selected right and left areas to be a difficult-to-see areas, from among the plurality of imaging areas, and the selection means is further configured to set the selected right and left areas as target areas, and the image generating device is configured such that the image of the right and left areas as target areas are displayed being enlarged compared to the image of the center area as the remaining imaging area. an acquisition means (S220, S225) for capturing an image of an imaging region around an own vehicle with a camera through a wide-angle lens, and acquiring image data, the imaging region being configured by a plurality of imaging areas (111 to 113); a determination means (S200 to S215) for detecting an object present around the own vehicle and determining whether the object is present in the imaging areas, on the basis of detection results; a selection means (S220, S225) for selecting a target area to be displayed in an easy-to-see state from among the plurality of imaging areas, on the basis of determination results derived from the determination means; a generation means (S220, S225) for adjusting a reduction degree of an image of at least one imaging area in the plurality of imaging areas such that the image of the target area is displayed in an easy-to-see state compared to the image of at least one remaining imaging area, and correcting the image data to generate display image data for displaying the entire imaging region; and a display means (S220, S225) for displaying the display image data, characterized in that: the imaging region horizontally extends around the own vehicle, the imaging areas are arranged in a row in a horizontal direction intersecting a forward direction of the camera and include a center area and right and left areas (111, 113), when the determining means determines that the object is not present in any of the imaging areas, the selection means is configured to select the right and left areas as imaging areas that are difficult for a driver to directly see during driving and determines such selected right and left areas to be a difficult-to-see areas, from among the plurality of imaging areas, and the selection means is further configured to set the selected right and left areas as target areas, and the imaging region horizontally extends around the own vehicle, the imaging areas are arranged in a row in a horizontal direction intersecting a forward direction of the camera and include a center area and right and left areas (111, 113), when the determining means determines that the object is not present in any of the imaging areas, the selection means is configured to select the right and left areas as imaging areas that are difficult for a driver to directly see during driving and determines such selected right and left areas to be a difficult-to-see areas, from among the plurality of imaging areas, and the selection means is further configured to set the selected right and left areas as target areas, and
