N separately-exposed images are serially captured in an additive-type image stabilization processing that generates one synthetic image having reduced influence due to camera shake by positioning and additively synthesizing a plurality of separately-exposed images. For each non-reference image (I<SUB>n</SUB>), the strength (the degree of similarity) of a correlation between a reference image (I<SUB>o</SUB>) and each of the non-reference images is evaluated. Each of the non-reference image is determined whether valid or not according to the strength of each correlation. By using the reference image and valid ones of the non-reference images, a synthetic image is generated by additive synthesis.
