  • Patent number: 8711490
    Abstract: A lens system includes: a lens unit; a drive unit driving the lens unit in an optical axis direction; a detector detecting a position of the lens unit; a lens operation unit that operates driving of the lens unit; and a computing unit that computes a positional command value for controlling driving of the lens unit based on a signal input from the lens operation unit and controls driving of the lens unit; a time setting unit; and a threshold setting unit setting a positional difference threshold for switching the first and second current values set in the drive unit. When the difference between the positional command value and the lens position is larger than the positional difference threshold and duration after the second current value is set has not exceeded the high-current maximum time, the second current value is set. In other cases, the first current value is set.

  • Patent number: 8649667
    Abstract: A drop sensor detects a drop of a device. When the drop of the device is detected, a sub CPU allows a counter to count a drop time. When the device drops for a predetermined time or more, the sub CPU controls a regulator so that the regulator forcibly disconnects an electric power to be supplied to a hard disc, and writes a drop occurrence flag into a nonvolatile memory. When the power supply is again turned on, a main CPU allows a display section to display information indicating that the power supply is disconnected due to the drop of the device.

  • Patent number: 8254770
    Abstract: A lens apparatus supported by a support member, includes a pan/tilt detection portion for determining whether or not a pan operation and a tilt operation of the support member are performed, based on pan/tilt operation information output from the support member, an image blur correction lens for correcting an image blur, a vibration detection portion for detecting vibration of the lens apparatus, and calculating an amount of the image blur, and an image stabilizing portion for driving the image blur correction lens based on the amount of the image blur. The pan/tilt detection portion resets the vibration detection portion when the pan/tilt detection portion determines that one of the pan operation or the tilt operation is performed, and releases the reset of the vibration detection portion when the pan/tilt detection portion determines that the one of the pan operation or the tilt operation is not performed.
