An image processing apparatus comprises an image obtaining unit configured to obtain an omnidirectional image, a traveling direction obtaining unit configured to obtain information on a traveling direction of an image capturing apparatus when the omnidirectional image was shot, and a processing unit configured to perform processing of panoramic expansion on the omnidirectional image obtained by the image obtaining unit, based on the information on the traveling direction obtained with the traveling direction obtaining unit, such that an image portion corresponding to the traveling direction is positioned at a horizontal center in a panoramically expanded image, wherein the processing unit performs processing of panoramic expansion in accordance with change in the traveling direction in a case where the traveling direction changes while shooting the omnidirectional image that is a moving image.
