摘要
Disclosed is a method of generating an inverse conversion table capable of enabling the acquisition of an image prior to viewpoint conversion being performed on a predetermined image. A method of generating an inverse conversion table generates an inverse conversion table T1 for generating from a viewpoint-converted image an image prior to viewpoint conversion processing relating to the viewpoint-converted image as an inversely converted image. A control unit 11 calculates the distance L(a,b) between a conversion reference coordinate P(a,b) stored in a table coordinate (a,b) of a viewpoint conversion table T2 and a calculation-target table coordinate (i,j) of an inverse conversion table T1 for each conversion reference coordinate, and calculates an inverse conversion reference coordinate A(i,j) which is stored in the calculation-target table coordinate (i,j) of the inverse conversion table T1 on the basis of the distance L(a,b) between the table coordinate (a,b) of the viewpoint conversion table T2 and the conversion reference coordinate stored in the table coordinate (a,b).
