A mobile body surroundings display method performed by a mobile body surroundings display apparatus including an image capturing element that is mounted on a mobile body and acquires surroundings information by image capturing, a controller that creates a captured image using the surroundings information and a virtual image representing a situation around the mobile body, and a display that displays the virtual image, the method comprising:

• dividing the virtual image around the mobile body into a plurality of parts, calculating a level of attention for each of regions corresponding to the divided parts of the virtual image, and detecting a region the level of attention of which is equal to or above a predetermined value, as an attention-required range;
• creating the captured image of the attention-required range;
• displaying the attention-required range by use of the captured image, wherein the captured image is an actual captured image, and the virtual image is different from the actual captured image and is created such that information contained in the image is less than that of the actual captured image;
• and
• displaying a synthesized image in which the attention-required range on the virtual image is replaced with the actual captured image on the display, wherein the virtual image is a computer graphic image representing the surroundings information of the mobile body.
