In an image processing apparatus according to an embodiment, a movement-direction-change determining unit (755) determines the change of a movement direction between images. A movement-direction-change image extracting unit (751) extracts an image of which the movement direction is changed. Then, an image display controller (761) performs a control for sequentially displaying images constituting time-series images in time sequence. At this time, a display speed controller (763) controls the display speeds of the image extracted by the movement-direction-change image extracting unit (751) and the predetermined number of images that are continuously located before and after the image, at a level relatively lower than the display speeds of the other images.
