A monitoring system includes a camera module configured to photograph a subject, a laser distance sensor configured to sense a distance to the subject, the laser distance sensor being arranged in a line with the camera module, and a processor configured to acquire a first angle and a first sensing value of the laser distance sensor in response to an event, calculate a first distance between the camera module and the subject by using the first angle and the first sensing value, calculate a second angle by using the first distance, a laser angle of view of the laser distance sensor, and a laser angle of view length of the laser distance sensor, rotate the laser distance sensor up to the second angle when a difference between the first angle and the second angle exceeds a predetermined range, and acquire a second sensing value of the laser distance sensor.

Monitoring system and operation method thereof

Provided is an optical device including an optics including at least two moving groups that are movable along an optical axis and share portions of driving regions; a plurality of actuators configured to move the at least two moving groups along the optical axis, respectively; and a control unit configured to control the positions of the at least two moving groups by operating the actuators, wherein the control unit moves the at least two moving groups independently, such that the position coordinates of the at least two moving groups in one integrated coordinates system do not coincide with each other.

Optical device and driving control method of optical device

A method of correcting an optical axis of a zoom lens includes obtaining a degree of optical axis misalignment corresponding to a current zoom lens state of a camera, considering the current zoom lens state of the camera and data previously stored to define a relationship between a state of the zoom lens of the camera and the degree of optical axis misalignment, determining digital zoom information to compensate for the degree of optical axis misalignment, considering the degree of optical axis misalignment, and generating correction image data by cropping and magnifying image data photographed by the camera to correspond to the digital zoom information.

Method, apparatus, and computer program for correcting optical axis of zoom lens

A zoom tracking method performed by a control unit of a zoom camera includes operations (a) through (c). In operation (a), the control unit determines a focusing progress state at a time when a zooming start signal is received. In operation (b), the control unit narrows an estimated range of a subject distance or estimates the subject distance, according to the focusing progress state. In operation (c), the control unit performs focusing for a zoom magnification according to the narrowed estimated range or the estimated subject distance.

Zoom tracking method and zoom camera

An apparatus and method thereof determines a title of a recorded program. After a desired video content that is transmitted through a channel has been recorded upon user's request of timer recording, it is checked if more than one program is scheduled for broadcast on that channel during the preset timer recording interval based on broadcast program time information obtained from the channel. If it is determined that more than one programs is scheduled, the title of the recorded desired video content is determined on the basis of time length, data size, and/or minimum ratio.

Method and apparatus for determining title of recorded content

Embodiments of methods and apparatus for recording at least two broadcast programs that are consecutive in time can consecutively record the plurality of programs (e.g., consecutively) on a recording medium without a process of creating and recording navigation information between programs. Navigation information for the recorded section can be created and recorded on the recording medium after the consecutive recording of the plurality of programs is completed. Such navigation information can consider the consecutive broadcast programs as a single entity or a plurality of individual entities (e.g., for play back).
