<P>PROBLEM TO BE SOLVED: To propose a useful light receiving device and mobile apparatus having easy-to-use functions. <P>SOLUTION: The photoelectric converter includes a plurality of light receivers that have a quantum efficiency of ≥60% in every visible light zones and infrared zones and are regularly arranged to pick up images by lights of a plurality of wavelength zones, and ultraviolet ray information is obtained from this photoelectric converter. Skin information is obtained from the output of the visible light zones and infrared zones. The plurality of light receivers are loaded with the sensitivity of ultraviolet ray including zones that do not pass through a glass imaging lens. The imaging lens are functioned as a low-pass filter, and when inserted into an incident light path, the UVA information of narrow wavelength zones is obtained, and when retreated, an ultraviolet ray of wide wavelength zone necessary for calculating the UV index is received. The difference of images due to lights with greatly different wavelengths is corrected by a correction value. When the ultraviolet ray information is more than predetermined, the skin information is automatically acquired during the usage of the mobile device, and both are displayed at the same time. <P>COPYRIGHT: (C)2011,JPO&INPIT |
