1. An image processing apparatus, comprising: a central processing unit (CPU) configured to: detect a representation of a first object, a representation of a second object and a representation of a living subject in a captured image based on depth information that indicates a distance from a sensor, wherein the first object and the second object are worn by the living subject; determine image processing for the representation of the first object based on a shape and a length, in a first direction, of the representation of the second object; modify a shape of the representation of the first object to generate a modified representation of the first object based on the determined image processing to match the shape of the representation of the second object; combine the modified representation of the first object with the captured image based on the determined image processing to obtain a processed captured image; and display, in a display unit, the processed captured image.
