Abstract

借助于参考图符显示全景图像,所述参考图符帮助用户形成一个概念:全景图像是作为其被展示的圆柱表示被显示的。在图像上下方的图符由其基本上呈椭圆的形状表示一个圆柱。图符还包括具有参考标记的左右延伸,所述参考标记给出圆柱表面正在被展示的印象。结果,用户能够更容易地理解全景图像的不同部分中的物体之间的关系。

Description

图符参照的全景图像显示
本发明涉及显示；特别涉及全景显示。
过去，全景图像作为一个延伸的全景显示被显示。图1说明这种显示。可以认为图1是一个被在显示器上显示的圆柱全景图。不幸的是，这种显示不能使用户辨别方向。例如，沿箭头10所示的方向看的用户不能清楚地理解从箭头10看的景象为何差了180度。因而，需要一种更清楚地表示全景图像的显示。
本发明通过借助于参考图符显示全景图像来解决上述问题，所述参考图符帮助用户形成全景图像以圆柱表示而被显示的概念。在图像上下的图符通过其基本上呈椭圆的形状表示一个圆柱。图符也可以包括具有参考标记的左右延伸，所述参考标记给出被显示的圆柱表面的印象。结果，用户更容易理解在全景图像的不同部分中的物体之间的关系。
图1说明现有技术的全景显示；
图2是显示系统的方块图；
图3说明图像数据和观看方向之间的关系；
图4说明用于存储图像数据的存储器结构；以及
图5说明具有一个图符的一部分全景显示。
图2是利用图5的显示的全景系统的方块图。全景图像源或镜头50对模数转换器52提供代表全景图像的全景信号。模数转换器52向显示存储器54提供代表全景图像的数据。显示存储器54使用控制器56提供的地址存储图像数据。控制器56可以是微处理器或微控制器。当图像数据被提供给用户进行显示时，由控制器56提供地址。控制器56根据用户选择的观看方向提供读地址。还可以随机地选择观看方向，并且控制器56按照随机的观看方向向显示存储器54提供读地址以便读出数据。如果显示装置56具有数字输入，则从存储器54读出的全景图像数据可以直接地提供给显示装置56。对于模拟显示装置，例如显示装置60，则使用数模转换器58向其提供图像信号。也可以通过通信网络62向远距离显示装置64发送全景图像数据。因为用户可以选择观看方向，用户的输入例如可以由游戏棒66或游戏棒68提供，其中游戏棒68通过通信网络62提供用户输入。
图3是全景图像的圆柱表示，其说明观看方向和构成全景图像的图像数据之间的关系。数据可被认为是许多数据列，其表示围绕中心点92形成圆柱的象素。例如，在参考线94和96之间的列可被认为是这样一些数据列，其代表由箭头98的方向在每侧具有45度视野而获得的象素。
图4说明显示存储器54的结构，其中存储参照图3讨论的图像数据。为清晰起见，提供参考线94，96，100L，100R和102，用于表示图3中的圆柱部分和图4中的存储器部分之间的关系。(100L和100R可被认为分别是图3中的线100的左右部分。)相应于图3的列的数据被写入图4的列中。例如，相应于图3的列110，112和114的列的数据分别被写入图4的列116，118和120中。对于图3的所有的数据列，重复这一处理。
一旦数据被存储在图4所示的显示存储器54中之后，控制器56便产生用于从存储器读出数据的地址，以便按照用户的输入进行显示。
在显示区域上被显示的图像数据如图5所示，图5表示一个显示区域140，其具有上下相邻的基本上呈椭圆的图符142和144。上图符142的标记146和下图符144的标记148表示由用户选择的观看方向。如果上图符142的右部分150和左部分152具有不同的颜色、阴影或影线将特别有帮助。如果图符144的右部分154和图符142的右部分150具有相同的颜色、阴影或影线，并且如果图符144的左部分156和图符142的左部分152具有相同的颜色、阴影和影线也是有帮助的。全景图像可被认为是被显示的圆柱图像。利用图符142和144帮助用户形成这个概念。为了表示全景图像正在被由图符142和144表示的圆柱进行显示，上图符142的部分158向左延伸，并可以和部分152具有相同的颜色、阴影或影线。同样，图符144的部分160向左延伸，并和部分156具有相同的颜色、阴影或影线。用类似方式，图符142的右部分162向右延伸，并可以和部分150具有相同的颜色、阴影或影线。图符144的部分164向右延伸，并和部分154具有相同的颜色、阴影或影线。这些颜色和图形帮助观众在显示区域140的全景图像内确定方位。
再次参看图4并回忆起列118相应于在选择的视野的中心的数据，相应于列118的数据被提供在由标记146和148指示的位置。开始时，把列118-n/2的数据提供给显示区域的最左端，然后，沿着箭头166的方向继续提供由存储器读出的其它列，这样，图像数据被提供给显示区域140。当在存储器中的右位置110R被达到时，地址返回，并再次在列100L开始，直到所有的数据都被提供给显示区域。可能需要连续显示超过118±n/2范围的图像，使得显示范围大于360度。
也可以在上图符142中包括参考标记172和174。参考标记172相应于图符部分158的参考标记176，参考标记174相应于图符部分162中的参考标记178。同样，下图符144包括参考标记180和182，参考标记180相应于图符部分160的参考标记180，参考标记182相应于图符部分164中的参考标记186。通过指示全景图像的圆柱表示的标记172和180相应于被展示的表示的标记176和184，这些参考标记组进一步帮助用户在全景显示中辨别方向。同样，圆柱表示的标记174和182相应于展示的表示的标记178和186。
