  • Patent number: 11575839
    Abstract: An apparatus includes an imaging unit that captures an image, a zoom drive unit that controls an angle of view of the imaging unit, a pan drive unit that rotates the imaging unit in a pan direction, a tilt drive unit that rotates the imaging unit in a tilt direction, and a control unit that controls the pan drive unit and the tilt drive unit. The control unit controls accelerations or decelerations of the pan drive unit and the tilt drive unit based on the angle of view controlled by the zoom drive unit so that an acceleration time or a deceleration time of movement of a video shot by the imaging unit is made constant.

  • Publication number: 20220006957
    Abstract: An imaging apparatus includes an imaging unit, a zoom driving unit, an extraction unit, a shake detection unit, a shake correcting unit, and a control unit configured. The imaging unit is configured to capture an image formed by an imaging optical system. The zoom driving unit is configured to change an angle-of-view of the imaging optical system. The extraction unit is configured to extract an area in which a motion vector can be detected in the captured image. The shake detection unit is configured to detect an amount of shake of the image based on the motion vector in the extracted area. The shake correcting unit configured to correct shake of the image based on the detected amount of shake. The control unit is configured to control the zoom driving unit to prevent the extracted area from deviating from a field of view of the imaging optical system.

  • Patent number: 9794465
    Abstract: A network camera includes a pan driving unit and a tilt driving unit for changing a shooting direction of an imaging unit. A detection unit detects rotation angles of movable units to be driven by the pan driving unit and the tilt driving unit. A pan/tilt control unit corrects a target position of the movable unit according to a correction value according to the detected rotation angle and controls each of the driving units using a value after the correction. In addition, when masked image drawing for processing an image is performed so that a partial image of a predetermined position is not visible in the image captured by an imaging unit, an image processing unit performs a process of correcting a rotation angle detected by the detection unit according to the correction value and drawing a masked image at a mask drawing position after the correction.

  • Publication number: 20170251139
    Abstract: The image capturing apparatus includes a communication unit that receives a start command to start the rotation of an image capturing unit and a stop command to stop the rotation of the image capturing unit from a client device through a network; a pan-tilt control unit that starts the rotation upon receiving the start command with the communication unit 1009; and a system control unit that, upon receiving the stop command with the communication unit, determines whether the amount of rotation of the image capturing unit after the start command is received by the communication unit 1009 until the stop command is received is a predetermined amount or more, wherein if it is determined that the amount is not the predetermined amount or more, continues the rotation until the amount of rotation becomes the predetermined amount or more.

  • Patent number: 9723195
    Abstract: An image capturing apparatus that communicates with an external device includes a field-of-view changing unit configured to change a field of view for capturing an image of a subject, a receiving unit, a control unit, and an amount-of-change determination unit. The receiving unit receives, from the external device, a command for controlling the field-of-view changing unit. The control unit controls, when the receiving unit receives a command to start to change a field of view, the field-of-view changing unit to start to change the field of view. The amount-of-change determination unit determines an amount of change in the field of view. The control unit controls the field-of-view changing unit such that the determined amount of change in the field of view becomes a predetermined amount or more, irrespective of whether the receiving unit receives a command to stop changing the field of view using the field-of-view changing unit.
