  • Publication number: 20170276902
    Abstract: In order to perform an autofocus operation, a controller of a focus control device selects subject information relating to the current magnification from subject information including previous focus states stored in a storage unit in advance, and determines a focus lens driving range on the basis of a focal length associated with the selected subject information. After the focus lens driving range is determined, a contrast-based autofocus operation is performed within that driving range. Therefore, it is possible to reduce the time taken to obtain the focus state and improve reliability of the focusing.

  • Patent number: 9426352
    Abstract: A focus control apparatus reduces the degree of out-of-focus of an image of an intense point light source during zooming in contrast-based autofocus control. A zooming lens moves in an optical axis direction to perform magnification change and a focusing lens moves in the optical axis direction to perform focus adjustment and is driven in accordance with a trace curve corresponding to the distance to a subject. A controller evaluates, during the magnification change operation, based on the rate of change in the number of high-luminance pixels at which the number of high-luminance pixels in an output image from the imaging apparatus changes with the zoom magnification, whether or not the focusing lens is driven in accordance with a trace curve corresponding to the distance to the subject before the magnification change operation is performed or a trace curve corresponding to a distance to the subject of infinity.

  • Publication number: 20160173756
    Abstract: A controller sets a plurality of detection regions within an imaging area. The controller then compares a difference in a contrast signal level between a maximum contrast signal level and a minimum contrast signal level calculated from among contrast signal levels of contrast signals generated for the plurality of detection regions with a level difference threshold. The controller then sets a priority level in subject information concerning a subject on the basis of a comparison result. The controller then stores the subject information in a storage unit in accordance with the priority level set in the subject information. The controller then drives a focus lens on the basis of the subject information read from the storage unit so as to bring the focus lens into focus.

  • Publication number: 20140253788
    Abstract: In an imaging device having a driving device using a stepping motor, improvement in recovery speed after a step out of the motor is realized. An imaging device having a driving device which carries out lens driving, diaphragm driving or pan-tilt-zoom driving with a stepping motor, includes: a motor driving unit which controls a current or voltage supplied to an exciting coil of the stepping motor; a system control unit which outputs a motor driving stop instruction to the motor driving unit; and a detection unit which detects a current or voltage flowing through the exciting coil after the stop instruction is outputted. The system control unit finds a direction of correction and an amount of correction to recover from a movement of a rotor due to a step out of the stepping motor, based on the current or voltage detected by the detection unit, and moves the stepping motor based on the direction of correction and the amount of correction.

  • Patent number: 7830141
    Abstract: Coil is made to be disposed with gap opposed to the surface of wafer, and wafer stage is made to move in X and Y direction and R and ? direction. When supplying an alternating current to coil with the frequency swept by impedance analyzer, the magnetic field made to be induced in coil will operate on the conductive film of wafer. By changing a parameter (a frequency or an angle) influencing the skin effect of the conductive film and giving the parameter to coil, the state where a magnetic field is not made to penetrate relatively the film of wafer and the state where the magnetic field is made to penetrate relatively the film can be formed. From the variation of various values corresponding to the eddy current induced based on the change of state influenced by the skin effect of the conductive film, the film thickness of wafer can be measured with sufficient accuracy.
