Classical　PDE　methods　cannot　inpaint　＂big＂　missing　region.　In　order　to　overcome　this　problem,　a　new　technology　combining　numerical　interpolation　with　PDE　method　is　proposed　in　this　paper.　First,　an　interpolation　method　is　used　to　fix　the　curve(s)　to　connect　the　edge　which　is　interdicted　by　＂big＂　inpainted　region　block(s),　thus　the　block(s)　can　be　divided　into　smaller　parts;　then,　a　PDE　equation　is　used　to　fill　information　into　the　inpainted　region(s).　The　experimental　results　show　the　new　method　can　achieve　a　good　inpainting　quality　in　restoring　＂big＂　missing　regions.
