摘要： While a focus lens is moving to a focus lens driving target position, a controller of a focus adjustment device switches a moving speed of the focus lens from a first speed to a second speed. In particular, the controller calculates the number of times the defocus amount can be calculated when the focus lens moves at a predetermined speed in a section between a first position in which the moving speed is switched and a second position in which the focus lens starts being controlled to stop in the focus lens driving target position, and calculates the second speed based on the number of times, the first position and the focus lens driving target position.

摘要： A focus adjustment device includes a direction judgment unit and a control unit. A direction judgment unit calculates an evaluation value based on an image signal of a focus detection region, thereby judging a drive direction of a focus lens. The control unit controls a focus adjustment operation on the basis of the drive direction. The control unit causes the direction judgment unit to repeatedly judge the drive direction, and when the focus lens is slightly driven in a first direction judged on the basis of a first evaluation value and then the focus lens is slightly driven in a second direction judged on the basis of a subsequently calculated second evaluation value, the control unit forbids the slight driving of the focus lens in the first direction even though a drive direction judged on the basis of a further subsequently calculated third evaluation value is the first direction.

摘要： An image pickup apparatus a includes a VCM configured to move relative positions of an image sensor and a light beam such that a movement amount of a frame period is a non-integer multiple of a pixel pitch, a microcomputer configured to cause the image sensor to perform exposures a plurality of times during the movement of the relative positions and acquire a plurality of image data, and a combination processing section configured to generate high-resolution combined image data from the acquired plurality of image data. The VCM sets the movement of the relative positions during the exposures in a same moving direction and a same movement amount in each of the exposures of the plurality of times.

摘要： An image acquisition apparatus includes a display unit configured to display first display images corresponding to first sequential images generated by an imager unit by imaging simultaneously with second display images corresponding to range specifying sequential images received by a communication unit from at least another image acquisition apparatus, the range specifying sequential images respectively corresponding to second sequential images generated by imaging and being smaller in communication amount than the second sequential images. The image acquisition apparatus further includes an operation unit configured to receive a specified range which is a range in the second sequential images specified by a user operation based on the second display image displayed on the display unit, and a controller unit configured to cause the communication unit to receive the second sequential images including at least the specified range.

摘要： The liveness of routing protocols can be determined using a mechanism to aggregate liveness information for the protocols. The ability of an interface to send and receive packets and the forwarding capability of an interface can also be determined using this mechanism. Since liveness information for multiple protocols, the liveness of interfaces, the forwarding capability of interfaces, or both, may be aggregated in a message, the message can be sent more often than could individual messages for each of the multiple protocols. This allows fast detection of failures, and sending connectivity messages for the individual protocols, such as neighbor “hellos,” to be sent less often.
