  • Patent number: 11973417
    Abstract: A voltage drop Vzs is calculated based on an output current detection value Iac and a virtual synchronous impedance Zs or a corrected virtual synchronous impedance Zs?, and a value obtained by subtracting the voltage drop Vzs from an internal induced voltage Ef is output as a grid voltage command value Vac*. Zs calculation unit 7 limits an output current phase ? so that the output current phase ? is within an effective range by a phase limiter 12a, and calculates the corrected virtual synchronous impedance Zs? based on a limited output current phase ?, the internal induced voltage Ef, a grid voltage detection value Vac and a current limit value Ilim. Accordingly, in grid interconnection power conversion device that controls a virtual synchronous generator, it is possible to continue operation while suppressing an overcurrent and possess a synchronizing power generated by action or working of a virtual synchronous impedance.

  • Publication number: 20220400243
    Abstract: An image processing apparatus determines whether an image represented by image data includes two circular areas and executes predetermined processing on the image if it is determined that the image includes two circular areas. The image processing apparatus can recognize if the image data is taken with a dual-eye lens even when an image capture apparatus that has recorded the image data has not recognized that a dual-eye lens unit has been attached and processing the image appropriately.

  • Publication number: 20140037268
    Abstract: A moving image recording apparatus capable of, when recording of a video image to at least one recording medium is stopped in the process of simultaneous recording to a plurality of recording medium, recording a video image to other recording media and capable of preventing relevant video image IDs from being provided to the video images. A setting unit sets same identification information to moving images simultaneously recorded to recording media. When moving image recording to one of two recording media has been stopped but moving image recording to another recording medium is continued in the process of simultaneously recording moving images of same content to the two recording media, a control unit controls the setting unit such that identification information for which the recording has been stopped is differentiated from that for which the recording is continued.
