  • Patent number: 8922574
    Abstract: A liquid crystal display (LCD) device comprises an image signal processing unit that selectively compensates a current frame upon determining that it is part of a sequence of changing images as opposed to a sequence of still images. The image signal processing device comprises an encoding/decoding unit that generates comparison frame decoding data by encoding and decoding comparison frame data, generates reference frame decoding data by encoding and decoding reference frame data, and a determining unit that sets a comparison range based on effective bits in the comparison frame decoding data and effective bits in the reference frame decoding data, and compares the comparison frame decoding data and the reference frame decoding data within the comparison range.

  • Patent number: 8818118
    Abstract: An image encoding device includes a first compression unit, a second compression unit, a third compression unit and an output unit. The first compression unit generates first compressed data by compressing first data associated with a reference block in an input image. The second compression unit generates second compressed data by compressing second data associated with a current compressing block in the input image when the current compressing block corresponds to a first pattern. The current compressing block is included in the reference block. The third compression unit generates third compressed data by compressing the second data when the current compressing block corresponds to one of a plurality of second patterns. The output unit outputs compressed data based on the first compressed data, the second compressed data and the third compressed data.

  • Patent number: 7343238
    Abstract: Disclosed herein is a technology for controlling speed of a car. More specifically, the invention relates to a speed controller for a car using telematics, the controller comprising a sensor unit to detect the speed of the car, the distance from the car to an object in front, and the operating status of a brake pedal and an accelerator pedal, a telematics system to output a signal to control the travel speed of the car and a gear shifting signal, when the speed of the car and the distance from the car to the object in front exceeds a preset range of an approaching distance, a speed regulation system to maintain the travel speed of the car within a speed limit by controlling an accelerator pedal and a brake pedal control unit, and an automatic transmission system to set a gear shifting level by controlling a gear shifting lever control unit.

  • Publication number: 20070005213
    Abstract: Disclosed herein is a backward control system for an automobile using telematics. The system includes: a sensor unit to sense a backward speed, presence of a backward object, and the operating state of the brake pedal and the accelerator pedal of an automobile when backward-travelling; a telematics system unit to output a control signal, when a distance between the automobile and the object is within a pre-set range in response to the signal from the sensor unit, such that the backward-travelling is automatically interrupted to thereby prevent collision with the object; and a accelerator pedal control unit and a brake pedal control unit to automatically control the operation of the accelerator pedal and the brake pedal to thereby interrupt the backward-travelling in response to the control signal outputted from the telematics system unit.
