  • Patent number: 10999515
    Abstract: A status change estimating unit 501 estimates a change in lens status of an interchangeable lens 21. A warning control unit 502 determines whether user setting lens status set by a user for the interchangeable lens 21 through a user interface unit 41 or a communication unit 43 and interchangeable lens status are the same. In a case where the warning control unit 502 determines that the user setting lens status and the interchangeable lens status are different from each other, the warning control unit 502 outputs warning information to a warning unit 42 to warn the user. This configuration enables the user to recognize a difference between the user setting lens status and the interchangeable lens status by the warning issued by the warning unit 42.

  • Patent number: 10944942
    Abstract: In a case where it is determined by a reliability determination section 501 that retention aberration information of an in-apparatus aberration information retention section 31 is unreliable, a control section 50 sets detection aberration information generated by performing aberration detection processing by a lens aberration detection processing section 32 as application aberration information for correcting an aberration of a captured image. In a case where it is determined that the retention aberration information is reliable, the control section 50 sets the retention aberration information as the application aberration information. Aberration information can be generated if necessary.

  • Publication number: 20200258990
    Abstract: To allow a metal oxide film composed mainly of O and at least one of Hf and Zr to exhibit ferroelectric properties. After deposition of a hafnium oxide film on a semiconductor substrate via an insulating film, the semiconductor substrate is exposed to microwaves to selectively heat the hafnium oxide film. This makes it possible to form a larger number of orthorhombic crystals in the crystals of the hafnium oxide film. The hafnium oxide film thus obtained can therefore exhibit ferroelectric properties without adding, thereto, an impurity such as Si. This means that the hafnium oxide film having a reverse size effect can be used as a ferroelectric film of a ferroelectric memory cell and contributes to the manufacture of a miniaturized ferroelectric memory cell.
