Various embodiment pertain to an integrated circuit device, such as smart cards, electronic wallets, PC cards, and the like, and various methods for modifying data values held by the device. Next, when digital portable telephone B transmits a CALL SETUP signal and a sending number to digital portable telephone A, digital portable telephone A transmits a CALL PROC signal and an ALERT signal to digital portable telephone B. The image data is compared to a plurality of stored image data that includes baseline measurement values associated with an expected condition level of baseline locations within a baseline geographical area. The color of the light of the light emitting diode on the first arrangement surface and the second arrangement surface are set such that the SP ratio of the scotopic luminance to the photopic luminance of the light emitting diode on the second arrangement surface is greater than that of the first arrangement surface.
