摘要： 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 14, after a process of clipping a central region 31 and an image reversing process are performed in each of image pickup regions 3 of microlenses on image pickup data D1 obtained by an image pickup device 13, an image synthesizing process using images is performed to obtain image-processed data (image pickup data D2). In the image pickup data D2, the process of clipping the central region 31 is performed in each of the image pickup regions 3 of the microlenses, so even if a living organism 2 as an object subjected to image pickup is closely placed, an overlap region 32 between the image pickup regions 3 by adjacent microlenses is removed. In addition, the range of the central region 31 may 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) 2 and a microlens array 12.
