    • Disclosed herein is an object image capture apparatus. The object image capture apparatus includes a first camera unit, a second camera unit, and a control unit. The first camera unit obtains a wide-area view image by capturing a wide-area view region. The second camera unit obtains a close-up view image by capturing the close-up view region of the wide-area view region. The control unit controls the second camera unit by dividing the wide-area view image into a plurality of blocks, analyzing the resulting blocks, and defining a target block, in which a moving object is detected, as a close-up view region from among the plurality of blocks.
    • 这里公开了一种物体图像捕获装置。 对象图像捕获装置包括第一相机单元,第二相机单元和控制单元。 第一相机单元通过捕获广域视图区域获得广域视图图像。 第二相机单元通过捕获广域视区的特写视图区域来获得特写视图图像。 控制单元通过将广域视图图像分割成多个块来控制第二相机单元,分析所得到的块,并且将检测到移动物体的目标块定义为从其中的特写视图区域 多个块。

    • Disclosed are a method and apparatus for masking a privacy area of an image. The method for masking a privacy area of an image includes: detecting a privacy area required to be protected in an image; and performing masking on the image. An important area (a face area of a person, a number plate area of a vehicle, a window area of a house, etc.) detected from an image inputted through a CCTV camera can be effectively and easily encrypted, scrambled, decoded, and descrambled. Also, the position of the important area detected before or after the important area is scrambled can be maintained to be consistent without having to use a metadata file. In addition, a scrambling algorithm of the same key value can be applicable regardless of the size of the important area. As a result, the system efficiency can be enhanced by effectively protecting personal information compared with a CCTV-based video security system.
    • 公开了一种用于屏蔽图像的隐私区域的方法和装置。 用于屏蔽图像的隐私区域的方法包括:检测图像中需要保护的隐私区域; 并对图像执行遮蔽。 从通过CCTV摄像机输入的图像检测到的重要区域(人的面部区域,车辆的车牌区域,房屋的窗户区域等)可以被有效且容易地加密,加扰,解码和 解扰了 此外,在重要区域之前或之后检测到的重要区域的位置被加扰可以保持一致,而不必使用元数据文件。 此外,无论重要区域的大小如何,都可以应用相同键值的加扰算法。 因此,与基于CCTV的视频安全系统相比,通过有效保护个人信息可以提高系统效率。

    • A dimming structure for an image display device further includes a contrast panel for altering contrast differences in a portion around an outputted image to achieve dimming effects on an image smaller than a light emitting lamp. In the dimming structure, a backlight unit has a plurality of light sources disposed therein. A display panel displays an image while the backlight unit is disposed to light the display panel. A contrast panel is disposed between the backlight unit and the display panel. The contrast panel has a light emitting window formed in a portion thereof corresponding to the image of the display panel to transmit light emitted from the backlight unit therethrough. The dimming structure assures uniform dimming effects on the portion around the image despite use of a light source bigger than the image to be outputted.
    • 用于图像显示装置的调光结构还包括对比度面板,用于改变输出图像周围部分的对比度差异,以实现对小于发光灯的图像的调光效果。 在调光结构中,背光单元具有设置在其中的多个光源。 显示面板在布置背光单元以点亮显示面板的同时显示图像。 对比度面板设置在背光单元和显示面板之间。 对比度面板具有形成在其对应于显示面板的图像的部分中的发光窗口,以透射从背光单元发射的光。 调光结构确保了对图像周围部分的均匀调光效果,尽管使用大于要输出的图像的光源。
