Patent ID: 7956897

Claim:
An image combining device comprising: a motion vector calculating portion which calculates a motion vector between different divided exposure images of a plurality of divided exposure images obtained as a result of continuous shooting, wherein the image combining device positions the divided exposure images based on the motion vector thus calculated, and combines the divided exposure images together one on top of another so as to form one composite image, wherein the image combining device further comprises: a mixture proportion calculating portion which calculates, based on information commensurate with a motion of an image between the different divided exposure images, a mixture proportion of each divided exposure image to the composite image, wherein the image combining device combines the divided exposure images together one on top of another in mixture proportions thus calculated so as to form the composite image, wherein the motion vector calculating portion calculates the motion vector based on a plurality of cumulative total correlation values between the different divided exposure images, the plurality of cumulative total correlation values being obtained by an image matching method, wherein the mixture proportion calculating portion calculates the mixture proportions based on the plurality of cumulative total correlation values used as the information.
