A porous scintillator crystal capable of suppressing scattering of light that represents a high spatial resolution is provided. The sheath can prevent damage to the pouch in electronic devices to which the secondary battery is applicable as an inner pack type. A cover board rests on four support parts at the tops of the four columns and is restricted by four covering parts. In a second phase, the image is processed by means of processing to associate thereto a corresponding sequence of specific configurations detected among said plurality of configurations of pixels in an univocal way. The PGC information has cell information including information about type of object, identification information. Preferably, the device and method are used in an 802.
