An image pick-up apparatus is disclosed which allows a reduction in degradation of images associated with a changed image magnification due to movements in a focus direction during image pick-up operation. The image pick-up apparatus has an image pick-up controller which performs a plurality of image pick-up operations for producing a single image and performs focus adjustment operation before each of the image pick-up operations to produce a first plurality of images, and an information producer which produces information on an image magnification of each of the first plurality of images. The image-pickup apparatus also has an image producer which produces a second plurality of images based on the first plurality of images and the information on the image magnification, and an image combiner which combines the second plurality of images to produce a single image.
