PURPOSE:To make it possible to identify the type of a light source automatically, by constituting a device with an image sensor having three or more picture elements and a reflecting plate in which reference colors are aligned. CONSTITUTION:Incident light passes through a scattering plate 1 at first. Specified color picture elements are laterally aligned in a reflecting plate 2. The light, which is reflected with the reflecting plate 2, passes through a one- dimensional lens 3. Then the light is inputted into a one-dimensional array type sensor 4. The alignment of the colors in the reflecting plate 2 is intactly inputted into the one-dimensional array type sensor 4 without mixing of the colors of the picture elements of the reflecting plate 2 when the light passes through the one-dimensional lens 3.
