Example Embodiment

[0040] The privacy mask display control method of the ideal embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0041]First, as shown in FIG. 2, the privacy mask display control method of the present invention can be applied to a surveillance camera 100 provided on a pan / tilt device 200, or can be applied to a pan / tilt device 200 equipped with a surveillance camera. . The first embodiment applied to the above-mentioned surveillance camera and the second embodiment applied to the above-mentioned pan / tilt device 200 will be described in more detail below.

[0042] Fig. 6 is a diagram of the privacy mask displacement value information stored and managed in the surveillance camera according to the first embodiment of the present invention. The above-mentioned privacy mask shift value information (Privacy Mask Shift Value Information) is stored and managed in advance in a non-volatile memory (not shown) in the surveillanc...

Abstract

The invention relates to privacy cover up the display-and-control methods. In order to protect privacy, and so on and rely on the shake perturbation / tilt to operate mobile surveillance images shown by the overlapping shows Intra the privacy of concealment, use surveillance cameras in the reader to search for the tilt angle of the benchmarks set incompatible with the shake perturbation angle privacy concealment displacement values, so that the proper privacy to cover up a shake perturbation / Mobile operators to tilt, or when equipped with surveillance camera shake by perturbation / tilt devices shake perturbation / tilt operation, retrieval read tilt angle to set benchmarks for the different perspective shake perturbation compensation values used in the calculation of a mobile display with surveillance cameras privacy to cover up the virtual control of shaking after perturbation , available to use surveillance cameras to rely on surveillance cameras showed that with the privacy to cover up properly conducted shake perturbation / tilt to mobile operators, which can effectively prevent intra surveillance images shown by the result of specific clip shake perturbation / tilt and exposed out.

Description

technical field [0001] The present invention relates to a display control method for privacy masking, and more specifically refers to: the monitoring camera makes the privacy masking (Privacy Mask) overlapped and displayed in the monitoring image frame suitable for panning (Panning) and tilting (Tilting) in order to protect private life. ) operatively performs a privacy-masking display control method for mobile display. Background technique [0002] Fig. 1 is a schematic diagram of an embodiment of panning / tilting of a common surveillance camera by means of a panning / tilting device. The PTZ monitoring camera with pan / tilt / zoom function can be installed and used on the pan / tilter device attached to the canopy of a specific place responsible for monitoring. [0003] At the same time, the above-mentioned monitoring camera can change the monitoring area to different directions through the pan operation of horizontal rotation and the tilt operation of vertical rotation by the ab...
