Abstract: A vehicle compound-eye camera includes: a plurality of cameras arranged to be spaced apart from each other in a predetermined direction and disposed such that respective maximum image-pickup ranges of the plurality of cameras are partially shifted from each other in the predetermined direction; and a processor configured to set an overlapping image-pickup range in which each of the plurality of cameras picks up an image of a same target object from a different viewpoint. The processor is configured to set an image-pickup range of one of the cameras disposed on one end in the predetermined direction to have a relatively wide angle. The processor is configured to set an image-pickup range of another of the cameras disposed on the other end in the predetermined direction to have a relatively narrow angle.

Abstract: There are provided a radiation detector module, a radiation detector, and a radiographic imaging apparatus which make it possible to increase the row number while suppressing a length in a body-axis direction. The radiation detector module includes a detector substrate on which a scintillator, a photodiode, and AD conversion chips are loaded, and a control substrate which supplies power to the detector substrate and controls the operation of an AD conversion unit (AFE) of each AD conversion chip of the detector substrate. The plurality of radiation detector modules configure a radiation detector which suppresses the length in the body-axis direction by connecting together the two substrates so as to form a two-stage structure by stacking connectors.

Abstract: An overall loss L during non-execution of intermittent boosting (in ordinary boosting) is calculated from losses L1 and L2 of motors and a loss LC of a boost converter during non-execution of intermittent boosting. The overall loss L during execution of intermittent boosting is calculated from the losses L1 and L2 of the motors and the loss LC of the boost converter during execution of intermittent boosting. A minimum loss-time boosting voltage Vtmp at which the overall loss L provides a minimum loss Ltmp is set to a target voltage VH*. The boost converter is then controlled in a control state corresponding to the minimum loss-time boosting voltage Vtmp.
