    Abstract: 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.

    Abstract: A low-profile biometrics authentication system capable of achieving high security level authentication is provided. A biometrics authentication system 1 includes a light source 10, a light guide section 11A, a diffraction section 11B, a microlens array 12, an image pickup device 13, an image processing section 14, a pattern storing section 15, an authentication section 16, a voltage supply section 17, a light source driving section 181, an image pickup device driving section 182 and a control section 19. When light L0 emitted from the light source 10 propagates through the light guide section 11A by total reflection, and then enters the diffraction section 11B, light L1 diffracted at a different angle from an incident angle is generated. Thereby, the light guide section 11A functions as a surface-emitting light source, and total reflection conditions in the light guide section 11A are not satisfied, and the light L1 is guided to the outside of the light guide section 11A, thereby light is sufficiently applied to the inside of the living body 2.
