PROBLEM TO BE SOLVED: To provide a preparation method of filter data and program thereof that can relatively easily prepare an image for a lenticular lens by synthesizing the filter data with an original image.SOLUTION: A preparation method of filter data is configured to: acquire pattern data P1 of the almost same size as an original image, in which the pattern data P1 has an entire area set at a transmittance degree 0%; compart the pattern data into strip-like areas of the number of original images multiplied by the number of lenses, that is, compart the pattern data P1 into N*M strip-like areas DA by dividing a lens area LA corresponding to M lenses into N equal areas with N original images; make one strip-like area corresponding to the original image of N strip-like areas DA within the lens area LA in the pattern data P1 transparent to a transmittance degree 100% to prepare a stripe-shaped transmission filter F1 having a transmission area D1 shaped into a stripe; and resize the stripe-shaped transmission filter F1 to a size having the stripe-shaped transmission filter F1 multiplied by a ratio LP/LPr of a foreseeable lens pitch LP and an actual lens pitch LPr.SELECTED DRAWING: Figure 11 |
