摘要： A method for controlling a masking block in a monitoring camera. The method adjusts the masking block to precisely hide an image of a subject with its position and size changed when a zoom magnification is changed under a state where the masking block is set. In addition, the method adjusts a masking block to precisely hide a changed image of a subject when the monitoring camera is rotated to change the position of the image of the subject. In addition, the method measures and corrects a distance between a center axis of a CCD and an optical axis of a lens if the two axes are not coincident with each other. In addition, the method corrects an offset occurring due to an incorrect coupling between the monitor camera and a pan/tilter. Furthermore, a method for setting a masking block when a remotely uncontrollable monitoring camera is used is disclosed.

摘要： Disclosed herein is an image processing method. In an embodiment of the present invention, when areas having a luminance difference set by a user, for example, 45 dB or more, are preset in an image captured by a camera, an area, the luminance level of which exceeds a predetermined threshold level, may be displayed as a gray level or a black level, with the luminance thereof decreased by a certain luminance level, or may be displayed while a mask, having a gray or black level, and the area, the luminance level of which exceeds the predetermined threshold level, overlap each other. Therefore, glare caused by a high luminance subject can be decreased, or other subjects present in a backlit image can be easily recognized.
摘要翻译：这里公开了图像处理方法。在本发明的一个实施例中，当由用户设定的具有亮度差的区域（例如，45dB或更大）被预设在照相机拍摄的图像中时，其亮度等级超过预定阈值水平的区域可以被显示为灰度级或黑色级别，其亮度降低一定的亮度级别，或者可以在具有灰度或黑色电平的屏蔽以及亮度级别超过其的区域时显示预定的阈值水平彼此重叠。因此，可以降低由高亮度对象引起的眩光，或者可以容易地识别存在于背光图像中的其他对象。

摘要： The present invention makes a privacy protection area set on a video frame always match a masking block for the privacy protection area, thereby preventing video images taken from the privacy protection area from being exposed. One embodiment of the invention sets a masking zone corresponding to a privacy protection area on a taken video frame, keeps examining if the set masking zone does not match the privacy protection area, and adjusts the position of the masking zone on the video frame if it is determined that the masking zone does not match the privacy protection area, thereby preventing video signals taken from the initially set privacy protection area from being outputted.

摘要： A method and an apparatus for controlling a privacy mask display includes a monitoring camera which is if tilted and its tilt angle becomes greater than 90° when a privacy mask to mask a specific target object in a captured image frame is displayed, an image and the privacy mask in the frame are rotated 180° with respect to the CCD center axis, and the optical center axis stored in the apparatus is also rotated 180° with respect to the CCD center axis. Afterwards, if the zoom ratio of the monitoring camera changes, the size and position of the privacy mask are adjusted relative to the optical center axis rotated 180° with respect to the CCD center axis. It is therefore possible to freely perform zooming and tilting operations without danger of exposing the privacy-protected target object even under the condition that the optical center axis and the CCD center axis of the monitoring camera do not coincide.
摘要翻译：用于控制隐私掩模显示的方法和装置包括监视摄像机，如果在显示拍摄图像帧中隐藏特定目标对象的隐私掩码时，如果倾斜并且其倾斜角度变得大于90°，则图像和框架中的隐私掩模相对于CCD中心轴旋转180°，并且存储在设备中的光学中心轴也相对于CCD中心轴旋转180°。此后，如果监视摄像机的变焦比改变，则相对于相对于CCD中心轴旋转180°的光学中心轴，调整隐私掩模的尺寸和位置。因此，即使在监视摄像机的光轴中心轴和CCD中心轴不一致的情况下，也可以自由地执行变焦和倾斜操作，而不会暴露隐私保护目标对象的危险。
