PROBLEM TO BE SOLVED: To make a digital camera small-sized and to reduce costs while including a projector function. SOLUTION: There are provided a light source for emitting light; a first optical system including a projecting and photographing lens 3; a second optical system for returning the light from the light source on mirrors 6b and 6c and guiding the light to the first optical system; and an imaging device 8 capable of entering and leaving the second optical system. If the imaging device 8 is located inside the second optical system, the imaging device 8 receives light flux from an object via the first optical system. COPYRIGHT: (C)2006,JPO&NCIPI |
