An image pickup apparatus capable of improving the image quality of a picked-up image at the time of closely picking up an image is provided. In an image processing section, after a process of clipping a central regionand an image reversing process are performed in each of image pickup regionsof microlenses on image pickup data Dobtained by an image pickup device, an image synthesizing process using images is performed to obtain image-processed data (image pickup data D). In the image pickup data D, the process of clipping the central regionis performed in each of the image pickup regionsof the microlenses, so even if a living organismas an object subjected to image pickup is closely placed, an overlap regionbetween the image pickup regionsby adjacent microlenses is removed. In addition, the range of the central regionmay have a fixed value which is set in advance, or may be changed depending on a distance between the object subjected to image pickup (living organism)and a microlens array
