An image-taking apparatus including an auxiliary light projecting section that is small in size in spite of using multiple projection elements and is capable of performing extensive illumination to a range including parallax while maintaining a certain degree of brightness until reaching a given distance, and a projection module suitable for being loaded on the image-taking apparatus are provided. This apparatus projects light from three light points onto an object in a projection pattern shown in part (b) of Fig. 11 by use of a lens split into three regions. The light from the three light points is formed respectively into three beams by use of each of projecting sections subjected to region splitting, and single light beams out of sets of three beams are projected so as to overlap one another.
