Image processing apparatus, image processing method and projection system

An image processing method, comprising:

• calculating a position of each pixel of a plurality of pixels on a curved display surface based on a positional relationship between a viewpoint position set in front of the curved display surface and a virtual surface set behind the curved display surface,
• wherein the plurality of pixels forms a planar image generated for display on a plane;
• converting a pixel value of each pixel of the plurality of pixels based on a parameter that corresponds to the calculated position on the curved display surface, wherein the parameter that corresponds to the calculated position comprises enlargement/reduction ratio;
• and
• displaying the planar image on the curved display surface based on the conversion such that each pixel of the plurality of pixels is displayed at the calculated position.
