摘要： An image processing apparatus generates image data for projection by applying a deformation process to obtained image data based on an input parameter related to the deformation process. The image processing apparatus prohibits execution of the deformation process if it is determined that a magnification related to the deformation process based on the input parameter with respect to the obtained image data is out of a predetermined range.

摘要： The distance between projection coordinates to which the center of an image are projected and the center coordinates are added to the projection coordinates to obtain projection center coordinates. The distance is added to the coordinates to which the four corners of the image are projected to obtain projection four-corner coordinates. A distance shorter than the minimum of the distances between the projection four-corner coordinates and the projection center coordinates is decided as an output margin distance. Projection source coordinates to be projected to coordinates apart from the projection center coordinates by the output margin distance are obtained. A maximum of the distances between the projection source coordinates and the projection center coordinates is decided as an input margin distance. Divided images decided based on ½ of horizontal size of the image and the input margin distance are deformed and outputted.
