    Abstract: When cleaning is performed to remove kogation, which is deposited on a heat acting portion, by causing an electrochemical reaction through application of a voltage between an upper electrode and an opposing electrode, a wiring located at a periphery of the opposing electrode occludes hydrogen generated during the cleaning, thereby causing hydrogen embrittlement. A unit configured to heat the wiring connected to the opposing electrode is provided, and is driven during the cleaning or after the cleaning, to thereby force hydrogen out of the wiring. Thus, the hydrogen embrittlement of the wiring is suppressed.

  • Patent number: 9686447
    Abstract: A display apparatus includes a detecting unit that detects a start position and an end position of an effective image area of an analog image signal, and a determination unit that determines a candidate format as a format of the analog image signal if a first difference and a second difference satisfy a predetermined condition. The first difference represents a difference between the start position of the effective image area and a start position of an effective image area of the candidate format. The second difference represents a difference between the end position of the effective image area and an end position of the effective image area of the candidate format.

  • Patent number: 9686516
    Abstract: The present invention relates to improving configuration of wireless communication paths between devices in a video projection system comprising multiple wireless video projectors. When an initial radio communication setup is required between a managing node, e.g. a node comprising a master projector, and a node comprising a slave projector, for example following the powering up of the video projection system, the slave node receives setup information by radio communication means according to a sweeping sequence and transmits information by projecting sub-images. Sub-images advantageously comprise information relative to settings of the master node allowing reception in the corresponding slave node of a radio signal transmitted by the master node.

  • Patent number: 9686464
    Abstract: An image pickup apparatus that is capable of generating an album by laying out desired images in desired positions by a simple operation, while confirming a result of the layout by a photographer when shooting an image. A control section displays a through-the lens-image obtained by shooting an object on a display section by inserting the through-the lens-image in a plurality of frames on a template. When it is detected that one of the plurality of frames has been designated, the control section generates an image file by executing image pickup processing, and stores the generated image file in a storage medium in association with the designated frame of the plurality of frames on the template.

  • Patent number: 9686473
    Abstract: A camera system includes a lighting device comprising a movable unit including a flash unit, an imaging apparatus, a setting unit, an operation unit, and a control unit. The setting unit sets an irradiation position which is to be irradiated with light from the flash unit. The operation unit accepts an operation for starting photographing preparation operation. The control unit performs driving control of the movable unit. When the operation unit accepts an operation for starting photographing preparation operation, the control unit performs driving control of the movable unit for irradiating the set irradiation position with light from the flash unit. When the operation unit does not accept an operation for starting photographing preparation operation, the control unit does not perform driving control of the movable unit for irradiating the set irradiation position with light from the flash unit.

  • Patent number: 9686472
    Abstract: Provided is a compound-eye image pickup apparatus in which a plurality of imaging units, each of which configured to photoelectrically convert an optical image focused by a single focal lens with different focal length so as to output a signal, are arranged in the form of a matrix. An image processing unit performs an electronic zoom process for changing a cut-out area of an image and a filtering process for an image signal. A system controller obtains information relating a change in zoom magnification from a zoom changing unit and data relating to a zoom control method from a zoom control method storage unit so as to instruct a zoom controller to perform zoom control. Upon change of an angle of view by controlling the electronic zoom process and the switching of the single focal lens, the zoom controller controls the filtering process performed by the image processing unit so as to equalize the resolution before and after the switching of the single focal lens.
