  • Patent number: 10638916
    Abstract: In an endoscope device, a control unit brings an imaging device into an operation in a first read-out mode. In the first read-out mode, the imaging device reads out pixel signals from a plurality of pixels in a first time. After an instruction for the measurement of a subject is generated, the control unit brings the imaging device into an operation in a second read-out mode. In the second read-out mode, the imaging device reads out the pixel signals from the plurality of pixels in a second time. The second time is shorter than the first time. The control unit causes an imaging condition switching unit to switch imaging conditions on the basis of an operation of the imaging device in the second read-out mode.

  • Patent number: 10551175
    Abstract: In a first step, numbering with a reference field of view at one area set first by an operator being defined as an original point is performed. In a second step, a place adjacent to a side around the reference field of view is numbered, then the measurement range is automatically moved to sequentially execute measurement at that position, presence of shape data is checked, measurement results is stored, and, presence of shape data at the numbered position is recorded on a memory device. In a third step, field of view with shape data found therein as a next reference field of view is employed, a place adjacent to a side around the reference field of view is numbered, then the measurement range is automatically moved to sequentially execute measurement at that position other than a position at which measurement has already been made or no shape data is found.

    Abstract: According to one embodiment, generally, an information processing apparatus includes a vehicle detector, a stopped-vehicle evaluator, a parked-vehicle evaluator, and a determiner. The vehicle detector detects a vehicle from a captured image by an imaging device mounted in a probe vehicle. The stopped-vehicle evaluator calculates a stopped-vehicle evaluation value based on one or more stopped-vehicle conditions. The parked-vehicle evaluator calculates a parked-vehicle evaluation value based on one or more parked-vehicle conditions. The determiner determines whether the vehicle is stopped or parked based on both the evaluation values.
