  • Publication number: 20230077472
    Abstract: A wireless tag that is not guaranteed to be located within a predetermined area is prevented from being read as a valid wireless tag. A communication device includes: an antenna; a reference tag; a reception unit; and a determination unit. The reception unit uses the antenna to sequentially receive signals wirelessly transmitted from a reference tag whose relative position to the antenna is known and a reading target tag different from the reference tag. The determination unit determines that the signal transmitted from the reading target tag and received by the reception unit is invalid based on a phase of the signal transmitted from the reference tag and received by the reception unit.

  • Patent number: 11170511
    Abstract: The present disclosure relates to an image processing device, an imaging device, and an image processing method to superimpose a complementary image in such a manner that an appearance becomes more natural. From an image acquired by imaging of an arbitrary subject, a removal region selecting unit selects a region, in which an intended object to be removed is included, as a removal region with reference to distance information that is acquired when the image is imaged and that indicates a distance to the subject. Based on the distance information, a complementary region specifying unit specifies a complementary region to complement the removal region from a region including a background of the object to be removed in the image. An image superimposition processing unit superimposes a complementary image generated from the complementary region on a place from which the removal region is deleted in the image.
