    • A communication apparatus and a method for supporting carrier sense multiple access/collision detection (CSMA/CD) are disclosed. In a home network having a plurality of peripheral apparatuses in one home bus, the communication apparatus includes an interface circuit for transmitting and receiving packet data by being connected to the home bus; a data transmitting circuit for converting transmission data generated from inner peripheral apparatuses into physical transmission data and then for outputting the data on the home bus through the interface circuit; a data receiving circuit for determining whether data transmitted from other peripheral apparatuses through the interface circuit are received in its own peripheral apparatus and for checking a current state of the home bus; a collision detection circuit for continuously detecting a current state of the home bus through the data receiving circuit; and a communication controlling part for controlling data which are output form the data transmitting circuit by detecting a state of the home bus detected from the collision detection circuit.

    • A camera module includes an image distortion compensation apparatus configured to perform a method for compensating the image distortion caused by a sensor movement. A method of compensating an image distortion includes receiving an image including distortion caused by an movement of a sensor in a mode where two or more successive images are received. The method further includes calculating variation information using a relation between corresponding points of the received image (current image) and an adjacent image (previous image) which was previously received; and compensating the distortion included in the current image by making use of the variation information. The calculating variation information includes: calculating an actual homography value between the current image and the previous image; setting up the calculation based homography value including the variation information; and obtaining variation information having a minimum difference between the actual homography value and the calculation based homography value.
    • 相机模块包括被配置为执行用于补偿由传感器运动引起的图像失真的方法的图像失真补偿装置。 补偿图像失真的方法包括在接收到两个或更多个连续图像的模式中接收包括由传感器的移动引起的失真的图像。 该方法还包括使用先前接收的接收图像(当前图像)和相邻图像(先前图像)的对应点之间的关系来计算变化信息; 并且通过利用变化信息来补偿包括在当前图像中的失真。 计算变化信息包括:计算当前图像和先前图像之间的实际单应性值; 设置包括变化信息的基于计算的单应性值; 并获得具有实际单应性值和基于计算的单应性值之间的最小差异的变异信息。
