PREPARATION FOR STILL PICTURE FROM MOVING IMAGE

PROBLEM TO BE SOLVED: To relax an interlace interference by setting double the longitudinal direction correlation value of a correlation coefficient, which is found concerning even-numbered and odd-numbered fields when plural pieces of moving image data are frame image data, and synthesizing a still picture while using the correlation coefficient. SOLUTION: A field/frame discriminating part 20 discriminates captured moving image data are frame images corresponding to one frame of moving images and a field extracting part 22 alternately extracts the even-numbered and odd-numbered lines of the frame image from the moving image data and separates the data into even-numbered and odd-numbered field images. Next, a mutual coefficient determining part 24 respectively determines the correlation coefficient showing the relative relation of two continuous field images. A correlation coefficient working part 26 sets double the longitudinal direction correlation value of the correlation coefficient supplied from the correlation coefficient determining part 24. While using the provided correlation coefficient, a synthesizing processing part 28 synthesizes plural field images.
