Description
技术领域
本发明涉及利用视频移动电话的安全***,更具体的,涉及利用视频移动电话的视频处理器以检测运动的安全***。
背景技术
随着犯罪率持续增长,对于改善的安全***的需求也持续增长。一些安全***利用具有电荷耦合器件的特别的摄像机来感测运动和声音。利用摄像机,安全***检测移动物体和声音,以确定移动物体和声音中的任一个是否超过了阈值。如果运动或声音超过了阈值,则安全***报警以通知用户和/或存储与该报警相关的视频帧。
利用这样的安全***需要相对昂贵的装置和安装工作。因此,不论功能性如何,该安全***无法在普通家庭和办公室应用中实际使用。
发明内容
通过使用视频移动电话提供安全的装置和方法来解决现有技术中的这些和其他缺陷和缺点。具有视频移动电话的安全***包括运动检测。
本发明的实施例提供一种安全***,该安全***利用安装在视频移动电话中的视频处理器来感测外部运动物体,并发送报警信号和与报警相关的视频帧。
根据本发明的一个方面,利用移动电话的安全***包括具有安全功能的视频移动电话,用于捕获外部图像和确定来自所捕获到的外部图像的变化,以发送报警控制信号和视频帧;报警发生器,用于从视频移动电话接收报警控制信号以产生报警;和报警视频存储器件,用于接收和存储从视频移动电话发送的报警视频帧。
附图说明
根据示例附图,可以更好的理解本发明,其中:
图1是显示利用根据本发明原理的视频移动电话的安全***的示意图;
图2是显示图1的安全***的操作的流程图;
图3是显示图1的安全***的实施例的方框图;
图4A是显示图3中示出的视频处理器的第一实施例的方框图;
图4B是显示图3中示出的视频处理器的第二实施例的方框图;
图5是显示用于恢复DC系数和运动矢量的视频处理器的解码器电路的方框图,所述DC系数和运动矢量用于产生在图4B中示出的第二实施例中的压缩视频帧。
具体实施方式
提供一种具有移动电话的安全***来使能运动检测。本发明的实施例提供一种安全***,其利用在视频移动电话中安装的视频处理器来感测外部运动物体,并发送报警信号和与报警相关的视频帧。
在优选的实施例中,利用移动电话的安全***包括:具有安全功能的视频移动电话,用于捕获外部图像和确定来自所捕获到的外部图像的变化,以发送报警控制信号和视频帧;报警发生器,用于从视频移动电话接收报警控制信号以产生报警;以及报警视频存储器件,用于接收和存储从视频移动电话发送的报警视频帧。
图1是显示利用视频移动电话的安全***实施例的示意图,图2是显示图1的安全***的操作的流程图。
如图1中所示,利用视频移动电话的安全***包括:安全威胁100、用于观察该安全威胁的视频移动电话102、与视频移动电话信号通信的报警视频存储器104和与视频移动电话信号通信的报警发生器106。
转到图2,利用图1的视频移动电话的安全***包括用于设定安全模式的功能块S202,其将控制传送到功能块S204,以接受输入视频帧。功能块S204将控制传送到功能块S206,以比较和处理视频帧,接着,功能块S206将控制传送到检查运动的判定块S208。
如果没有检测到运动,则控制被送回到功能块S204。但是,如果检测到运动,则控制被传送至启动报警的功能块S210。功能块S210又将控制传送至存储报警视频帧的功能块S212。
这样,图1和图2的安全***实施例将具有安全功能的视频移动电话102安置在预料的入侵通道上,并设定安全模式(步骤S202)。在所述安全模式中,视频移动电话102接收由视频移动电话内部包含的摄像机所捕获的图像(步骤S204)。
视频移动电话102对外部图像的视频帧进行比较(步骤S204),以确定是否存在入侵100(步骤S208)。如果存在入侵100,则视频移动电话102可以通知安全服务或警察,或利用无线通信拨打一个预定的电话号码,并同时用报警发生器106产生报警(步骤S210)。同时,视频移动电话102将捕获到的当前外部图像无线地发送至诸如安全服务的服务器、邻接的计算机、或摄像机-录像机的报警视频存储器件,以此来保存证据。如果不存在入侵,则视频移动电话重复所述比较操作,直至由用户取消了安全模式。
图3是显示本发明的视频移动电话的详细方框图。
现在转至图3,利用视频移动电话的安全***实施例包括具有视频输入器件302的移动电话和与视频输入器件信号通信的视频处理器304。视频移动电话还包括与视频处理器信号通信的报警控制器306。所述视频移动电话的报警控制器与报警发生器106进行信号通信,而视频处理器与报警视频存储器件104进行信号通信。
如上所述,图3的视频移动电话利用安装在现有视频移动电话中的视频处理器运行安全功能,所述现有视频移动电话包括视频输入器件302、视频处理器304和报警控制器306。视频输入器件302使用安装的摄像机来捕获外部图像,并将所捕获到的外部图像的视频帧IS输入到图1的视频移动电话102。视频处理器304对从视频输入器件302输入的视频帧IS进行比较,以产生关于各帧之间的差异的结果值RIC,并根据输入控制信号对视频帧IS进行转换。报警控制器306根据由视频处理器304产生的结果值RIC控制报警。
当在图1或3的安全***中使用的视频移动电话102中设定了安全模式时,图1的视频移动电话102的视频输入器件302用所安装的摄像机捕获外部图像,并随后不断地将所捕获到的视频帧IS输入到视频移动电话102中。
视频处理器304对不断地从视频输入器件302输入的视频帧进行比较,以确定是否存在运动物体,并产生结果值RIS。另外,视频处理器304根据来自报警控制器310的控制信号CTR压缩视频帧IS并将其发送至报警视频存储器件104。
图4A和4B是显示根据本发明的视频处理器304的实施例的方框图。
如图4A所示,第一实施例的视频处理器304包括视频转换器402a,用于接收第一和第二输入信号并提供第一输出信号。视频处理器304还包括视频存储器件404a,用于接收第二输入信号。视频存储器件404a与视频比较器406a进行信号通信,用于提供第二输出信号。
这样,图4A的视频处理器实施例304包括视频存储器件404a、视频比较器406a和视频转换器402a。视频存储器件404a存储从视频输入器件302输入的原始视频帧IS或采样的原始视频帧。视频比较器406a对存储在视频存储器件404a中的多个视频帧IS2进行比较,以产生比较的结果值RIS。视频转换器402a根据控制信号CTR产生原始视频帧IS的压缩视频信号CIS。
图4B是用于产生比较的结果值的视频处理器304的另一个实施例,所述比较是利用从压缩视频信号CIS所产生的压缩视频帧AIS进行的。
转到图4B,第二实施例的视频处理器304包括视频转换器402b,用于接收第一和第二输入信号并提供第一输出信号。该视频转换器与压缩视频发生器404b进行信号通信。压缩视频发生器404b又与视频比较器406b进行信号通信,以提供第二输出信号。
这样,图4B的第二实施例的视频处理器304包括视频转换器402b、压缩视频发生器404b和视频比较器406b。视频转换器402b对原始视频帧IS进行压缩,以根据控制信号CTR来产生压缩视频信号CIS。压缩视频发生器404b利用压缩视频信号CIS的DC系数和运动矢量MV来产生压缩视频帧AIS,所述压缩视频信号CIS是在视频转换器402b中的解码期间产生的。视频比较器406b对压缩视频帧AIS进行比较,以产生比较的结果值RIS。
图5是显示用于恢复DC系数和运动矢量的视频处理器304的解码器电路的方框图,所述DC系数和运动矢量用于产生图4B中示出的实施例中的压缩视频帧AIS。
现在转到图5,图4B的视频处理器304的解码器电路包括用于接收第一输入的可变长度解码器502。可变长度解码器与逆量化单元504进行信号通信,所述逆量化单元504又与将第一正向的输入端提供至求和单元的逆DCT单元506进行信号通信。
可变长度解码器502还与压缩视频发生器404b的第一输入进行信号通信。压缩视频发生器404b的第二输入与逆量化单元504进行信号通信,压缩视频发生器404b用于提供压缩的视频输出。
可变长解码器502还与运动补偿器508的第一输入端进行信号通信,所述运动补偿器的输出端与求和单元的第二正向输入端进行信号通信。求和单元的输出端用于提供恢复的视频,并与运动补偿器508的第二输入端进行信号通信。
这样,通过图5中示出的解码器电路将压缩的视频信号CIS恢复成原始视频帧,例如根据运动图像专家组(“MPEG”)或联合图像专家组(“JPEG”)标准,通过视频处理器304的视频转换器402b来压缩压缩的视频信号CIS。
也就是说,当输入压缩的视频信号CIS时,解码器电路的可变长度解码器502、逆量化器504和逆离散余弦转换器506对原始视频帧的每个帧进行帧内压缩。运动补偿器508利用由可变长度解码器502产生的运动矢量MV对连续的原始视频帧进行帧间压缩。从而,恢复原始视频帧。
在上述的恢复处理中,压缩视频发生器404b利用由逆量化器504恢复的DC系数和由可变长度解码器502产生的运动矢量MV产生压缩的视频帧AIS。
图4A或4B各自的视频比较器406a或406b将输入视频帧IS2或AIS之间的相关性与由用户定义的阈值进行比较,以确定是否存在运动物体。在这样的情况下,可以如下面的公式所描述的,通过当前视频帧的像素亮度Yt(i,j)和任意在先的视频帧的像素亮度Yt-r(i,j)之间的差值的绝对值的总和来获得视频帧之间的相关性:
其中N和M是视频帧的垂直或平行轴的大小,(i,j)是像素的坐标值。
如果输入视频帧没有改变,则在公式1中使用的两个视频帧之间的相关性增加,以使得公式1的值近似于“0”。但是,如果存在运动物体,则两个视频帧之间的相关性减少,以致公式1的值急剧地增大。可以将当前视频帧Yt(i,j)与邻接的在先视频帧Yt-1(i,j)进行比较。但是,当仅存在轻微的运动时,公式1的值会在由用户定义的阈值限制之内线性地增大或减小。结果,可以检测到入侵。因此,参照公式1,即使是轻微的运动也可以通过将当前帧与可选的在先帧中的一个(例如,Yt-r(i,j))进行比较而被检测到。
视频比较器406a或406b以上述的方式对视频帧相互进行比较,并产生比较的结果值RIS至报警控制器306。报警控制器306根据输入结果值RIS产生控制信号CTR。如果作为比较的结果检测到运动物体,则报警控制器306输入控制信号CTR,以对报警发生器106和视频处理器304进行报警。根据控制信号CTR,报警发生器106报警,并且视频处理器304压缩输入的外部图像以发送至外部报警视频存储器件104。所发送的视频被存储在报警存储器件104中以用作证据。
这样,本发明的实施例提供了不需要额外的安装工作并且具有低成本的有效的安全***。相关领域的普通技术人员根据此处的教示能够容易地弄清本发明的这些和其他特征和优点。应当明白,可以以硬件、软件、固件、专用处理器或它们的结合的各种形式来实现本发明的原理。
尽管已经参照附图详细描述了示例性实施例,但应当明白本发明不限于那些精确的实施例,并且相关领域的普通技术人员可以在不背离本发明的范围和精神的前提下,对本发明作出各种改变和修改。试图将所有这样的改变和修改都包含在如随后的权利要求所阐明的本发明的范围之内。
