  • Patent number: 9791764
    Abstract: An image pickup apparatus that is capable of performing suitable automatic irradiation direction control in a case where the automatic irradiation direction control for a lighting device is operated by a plurality of operation members. The lighting device that changes an irradiation direction of a light emitting section is mounted or is attachable to the image pickup apparatus. A first operation member starts automatic irradiation direction control that drives the light emitting section to direct in a determined irradiation direction, and starts photographing preparation. A second operation member starts the automatic irradiation direction control. A control unit continuously performs the automatic irradiation direction control in operation without stopping when the second operation member is operated during the automatic irradiation direction control owing to the operation of the first operation member.

  • Patent number: 9354047
    Abstract: A rotational misalignment between semiconductor wafers constituting a bonded wafer is calculated. A light source is arranged at a position which is on a front side of an opening of a notch and which is separated from an outer edge portion of a bonded wafer by a predetermined interval, and outputs light to irradiate the outer edge portion of the bonded wafer including the notch. A camera receives and photoelectrically converts reflected light that is specularly-reflected by the outer edge portion of the bonded wafer including the notch among the light outputted by the light source in order to output a brightness distribution of the reflected light as an image. A computer analyzes positions of notches from the image outputted by the camera to obtain a notch position misalignment, and further calculates a rotational misalignment between semiconductor wafers using a center position misalignment between the semiconductor wafers.
