Image processing device and image processing method

An image processing device used on a mobile body, the device comprising:

• at least one processor or integrated circuit configured to function as:
• a determiner configured to determine one out of a plurality of combination patterns among which to classify different circumstances as to presence or absence of an object in a plurality of predetermined regions around the mobile body;
• and
• a generator configured to generate a composite image by projecting onto a virtual projection surface a plurality of shot images acquired by a plurality of cameras taking images of surroundings of the mobile body,
• wherein
• the generator is further configured to out of a plurality of projection surfaces corresponding to respective ones of the plurality of combination patterns, the plurality of projection surfaces prepared before the composite image is generated, select the projection surface used in generating the composite image in accordance with the combination pattern determined by the determiner, and
• the plurality of combination patterns include
• a first pattern in which the object is a plurality of objects, the plurality of objects being present next to the mobile body on both sides thereof,
• a second pattern in which the object is present next to the mobile body on one side thereof,
• a third pattern in which the object is present next to the mobile body on another side thereof, and
• a fourth pattern in which no object is present next to the mobile body on both sides thereof.
