A camera calibration apparatus has a parameter deriver adapted to find parameters for projecting images shot with N cameras (where N is an integer of 3 or more) onto a predetermined surface and merging the images together. The N cameras comprise a first camera, a second camera, . . . and an N-th camera. The i-th camera (where i is every integer between 1 and N, inclusive) shares a common shooting area with at least one of the other (N-1) cameras, so that there are a plurality of such common shooting areas in total. The parameter deriver finds the parameters based on the results of the shooting of the calibration patterns arranged in the common shooting areas with the corresponding cameras. The calibration patterns are arranged separate from one another.
