    摘要: A pickup driving apparatus, and particularly, a pickup-drive stabilizing apparatus for an optical disc player includes: a detector for detecting an inertia of a pickup relative to a movement speed of the pickup, when an instruction occurs to stop driving a sled motor that transversely shifts the pickup at a high speed for high-speed access; and a comparator that determines whether an inertia speed of the pickup has decelerated to within a range stable for tracking control by comparing the output signal of the detector with a preset reference signal and generates an output signal for starting the tracking control. Therefore, the pickup-drive stabilizing apparatus can stabilize the pickup of the optical disc player after performing high-speed information access on an optical disc.

    摘要: A digital photographing apparatus includes a plurality of image pickup units that capture a plurality of images, a first image processing unit that generates a single input image from the plurality of images, a second image processing unit that generates a display image comprising common angle of view information in which the angle of view information of each of the plurality of image pickup units with respect to the single input image overlap, and a display unit that displays the display image. Each of the plurality of images shows a different parallax with respect to a subject, and each of the plurality of image pickup units have angle of view information.

    摘要: A step motor control circuit that does not fix a reference voltage of a step motor control signal. The step motor control circuit may include a digital-to-analog (DAC) signal generator configured to generate first and second DAC signals in response to a step motor error signal, a gain adjust block configured to control gains of the first and second DAC signals in response to a control signal and output first and second step motor control signals, and a gain controller configured to output the control signal in response to a mode signal and a gain control signal, in which the first and second step motor control signals are pulse trains including a reference voltage, and the reference voltage may be a fixed voltage when the mode signal indicates a normal mode and the reference voltage may be a variable voltage when the mode signal indicates a power consumption reduction mode.
