Imaging apparatus and imaging method, program, and recording medium

An imaging apparatus that captures an object that changes temporally, the apparatus comprising:

• a first acquisition unit adapted to acquire a first overview image of the object;
• an input unit adapted to input lesion information of the object;
• a determination unit adapted to determine one or more reference points in a region, of the first overview image, in which there is less temporal change than in other regions by excluding, from the first overview image, a region corresponding to the lesion information inputted through the input unit, the region corresponding to the lesion information being a region in which the temporal change is greater than in other regions;
• a setting unit adapted to set, in the first overview image, a capturing position of the object where detailed capturing is to be performed;
• a registering unit adapted to register, in the case where a second overview image has been acquired for the same object as the object in the first overview image, the second overview image with the first overview image based on the one or more reference points in the first and second overview images;
• and
• a second acquisition unit adapted to acquire a detailed captured image of the object in a position corresponding to the capturing position of the first overview image in the registered second overview image.
