1. An image projecting apparatus, comprising: an image projector configured to project received original image data on an image projection surface; an area identifier configured to identify an obstruction area in which different content is displayed as compared to a normal projection surface to be projected based on the original image data; a layout modifier configured to modify a layout of an object included in the original image data that is projected, on the basis of the object and the obstruction area on the image projection surface; and an evaluator configured to obtain an evaluation value that indicates a relationship between a position of the object and the obstruction area in the original image data, wherein: the layout modifier modifies the layout so that the object is moved based on the obtained evaluation values, the layout modifier further modifies the layout of the object in the original image data on the basis of the evaluation value, the evaluator sets a plurality of different positions to which the object is movable in the original image data and obtains evaluation values for the respective positions of the object and the evaluator obtains the evaluation value also based on at least an amount of overlap between objects in the original image.
