  • Patent number: 9952966
    Abstract: When a controller receives a new command from a main controller during overwrite-deletion processing for a specific storage apparatus, the received command is stored at least until completion of the overwrite-deletion processing when the received command is a command to the specific storage apparatus. Alternatively, progression of overwrite-deletion process is stored and priority processing of the received command is executed. On the other hand, when the received command is not a command to the specific storage apparatus, processing for the command is executed.

  • Patent number: 9955078
    Abstract: An image shake correction device provided in an image pickup apparatus drives an image shake correction lens on the basis of detection information about shaking and corrects the image shake. An angular velocity sensor detects an angular velocity of shaking, and a motion vector detection unit detects a motion vector from a plurality of images that has been captured. An adaptive digital filter and an adaptive algorithm unit perform a process that generates a compensation value for a shake correction remainder, and FF (feed forward) control is performed in accordance with the result of the process. In the FF control, a filter coefficient of the adaptive digital filter is adjusted on the basis of the motion vector and a detection signal for shaking. The control filter calculates a feedback control amount so as to track the position of the image shake correction lens to a target position.

  • Patent number: 9955081
    Abstract: An imaging apparatus receives a command including a first coordinate value and a second coordinate value, from a client apparatus. A determination unit determines whether or not a target region exists at or near a boundary of an imaging range corresponding to the first coordinate value and the second coordinate value. In a case in which the determination unit determines that the target region exists at the boundary of the imaging range, a control unit adjusts an imaging range to include the target region. In a case in which the determination unit determines that the target region does not exist at the boundary of the imaging range, the control unit sets an imaging range to be captured, to the imaging range corresponding to the first coordinate value and the second coordinate value.

    Abstract: An image forming apparatus includes an image forming portion for forming an image, a human presence sensor for detecting presence of a human body adjacent the apparatus, and a controller capable of executing an adjustment process operation for the image forming portion when a first predetermined number of prints are produced. When the human presence sensor detects a human body in the neighborhood of the apparatus, the execution of the adjustment process operation is deferred to reduce the waiting time necessitated by the adjustment operation, but if a second predetermined number of prints are produced, the image forming operation of the image forming portion is interrupted, and the deferred adjustment process is executed.
