具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种显示控制方法的流程图，如图1所示，该方法可以包括以下步骤。
在步骤102中，根据用户的视力信息，判断被观察物是否属于用户能够清楚观察的对象。
在步骤104中，若不属于，则将获取的所述被观察物的图像进行放大展示。
其中，针对步骤102和步骤104中的各类处理特征，在本公开的技术方案中均存在多种可能的实现方式，下面分别对每一处理特征进行说明。
一、用户的视力信息
用户的视力信息是指用户的视网膜分辨影像的能力。由于不同用户的视力存在差异，比如有些用户可能存在近视、散光或远视等问题，都可能影响用户对被观察物的观察过程。
本公开的技术方案可以应用于可穿戴设备中，比如智能眼镜等，通过对用户的视力信息和被观察物的确定，可以自动推测出被观察物是否能够被用户清楚地观察，从而执行自动化的放大展示处理。
为便于说明，下述实施例中均以“智能眼镜”为例进行介绍；但本领域技术人员应该理解的是：本公开的技术方案显然也可以应用于其他非可穿戴的电子设备中，只 要该电子设备具有信息处理和图像展示能力(比如显示屏)，能够对被观察物进行识别，并且可以判断用户对被观察物的观察情况，即可用于本公开的技术方案。
1、主动检测
作为一示例性实施方式，智能眼镜可以主动对用户的眼睛进行验光，得到用户的视力信息。
智能眼镜对用户进行验光时，可以采用现有技术中的电脑验光过程，其原理为“视网膜检影法”。比如图2所示，用户在佩戴了智能眼镜后，智能眼镜可以用检影镜将一束光线投射到用户眼睛的屈光系统并直达视网膜，再由视网膜的反射光抵达检影镜时，实现对视力信息的检测。
其中，在验光过程中，还可以通过红外线光源及自动雾视装置对用户的眼球进行放松调节，并且通过光电技术及自动控制技术对用户眼睛的屈光度进行检查。
当然，除“视网膜检影法”之外的其他方法显然也可以应用于本公开的技术方案中，本公开并不对此进行限制。
2、用户输入
作为另一示例性实施方式，智能眼镜可以根据接收到的用户输入信息，且所述用户输入信息中包含所述视力信息。
如果用户了解自己的视力情况，可以直接输入自己的视力信息。比如可以在智能眼镜的显示屏内，示出视力信息的输入界面，该输入界面中包含输入键盘，并通过捕捉用户的眼球运动情况，确定用户视线在输入键盘上聚焦的按键，从而完成信息输入。
或者，如图3所示，智能眼镜可以与用户的智能手机等其他设备建立关联，则用户可以直接在图3所示的智能手机界面中，输入自己的视力信息。
3、网络获取
作为又一示例性实施方式，智能眼镜可以根据用户的已登录账号，读取与该已登录账号相关联的视力信息。
如图4所示，用户可以在智能眼镜上进行账号登录，该账号与用户自身存在一一对应的关联关系；因此，如果用户事先将自己的视力信息、身高、体重等各种信息存储在云端，那么智能眼镜就可以根据当前的已登录账号，通过互联网读取到用户的视力信息。
二、被观察物
“用户视野范围”可以理解为用户眼睛的观察范围，比如图5所示，用户视野范围在俯视方向上呈一扇形区域。
智能眼镜位于用户的眼睛前方，与用户眼睛的朝向一致，并且能够随用户头部的 转动而随之发生转动，因而可以认为智能眼镜上的摄像头的图像采集范围与用户视野范围基本一致。
然而，当用户的头部和眼睛的朝向不变时，虽然用户视野范围不会发生变化，但用户的眼球发生转动时，就会导致被观察物随之变化。因此，智能眼镜可以通过对用户的眼睛转动情况的记录，捕捉用户的视线特征，从而将用户视野范围内匹配于该视线特征的物体作为被观察物。
比如在图5中，通过捕捉到用户的左眼视线和右眼视线，从而将该左眼视线和右眼视线的交汇处的物体，作为本公开技术方案中的被观察物。
三、用户是否能够清楚观察被观察物
1、基于距离的判断
作为一示例性实施方式，可以获取被观察物与用户之间的间隔距离，并根据该间隔距离是否满足大于或等于预设可视距离，判断被观察物是否属于用户能够清楚观察的对象。
如图6所示，假定智能眼镜通过捕捉用户的视线特征，确定了用户视野范围内的被观察物A，并测得该被观察物A与用户之间的间隔距离为L1；以及，智能眼镜确定了用户视野范围内的被观察物B，并测得该被观察物B与用户之间的间隔距离为L2。
那么，如果用户具有近视问题，并且基于用户的视力信息，可以确定用户能够清楚观察的最远距离为L0，且L1＜L0＜L2，则确定被观察物A可以被用户清楚观察到，不需要进行放大展示，且被观察物B无法被用户清楚观察到，需要进行放大展示。
类似地，如果用户具有远视问题，并且基于用户的视力信息，可以确定用户能够清楚观察的最近距离为L0’，且L1＜L0＜L2，则确定被观察物A无法被用户清楚观察到，需要进行放大展示，且被观察物B可以被用户清楚观察到，不需要进行放大展示。
2、基于细节的判断
作为另一示例性实施方式，可以根据被观察物是否包含细节信息，判断被观察物是否属于用户能够清楚观察的对象。
举例而言，如果被观察物并不包含任何细节信息，比如图7所示的被观察物A为一堵白色的墙面，则放大展示实际上并没有什么意义；而如果被观察物包含细节信息，比如图7所示的被观察物B为一幅画，则可以通过放大展示，方便用户仔细查看这幅画的细节。因此，本实施例的技术方案中，关键在于如果确定被观察物中包含细节的情况。
实施方式一
智能眼镜可以获取被观察物的预设像素特征参数值的变化程度，然后根据预设像素特征参数值的变化程度是否满足大于或等于预设变化程度，判断被观察物是否包含细节信息。
在本实施例中，像素特征参数值可以为每一像素的任意一种或多种属性值，比如灰度值、每个颜色通道的色彩值等。以图7所示的“白墙”和“画”为例，前者图像上的所有像素均为“白色”，则对应的灰度值(此处以“灰度值”为例，也可以为其他类型的像素特征参数值)均相同，不存在灰度值的变化，从而确定其不包含细节信息；而对于后者，由于“画”中包含很多细节，比如颜色变化等，显然会导致各个像素的灰度值存在差异和变化，且变化程度较大(比如大于或等于预设变化程度)，从而确定其包含细节信息。
实施方式二
智能眼镜可以获取被观察物的周围物体，并根据被观察物的预设像素特征参数值的变化程度是否与其周围物体一致，判断被观察物是否包含细节信息。
在本实施例中，仍以图7为例。对于被观察物A，由于其属于“白墙”的一部分，则预设像素特征参数值的变化程度与周围物体一致，也就说明该被观察物A与其周围物体共同构成了一个很大体积的整体，则用户并不存在对其细节的观察需求，因而可以判定其不包含细节信息；而对于被观察物B，由于是挂在白墙上的一幅画，则预设像素特征参数值的变化程度与周围物体并不一致，并且存在较大的变化程度(比如大于或等于预设变化程度)，从而确定其包含细节信息。
3、基于时间的判断
作为又一示例性实施方式，可以获取用户观察同一物体的持续时间，或观察同一物体时的视线对焦时间，并根据持续时间或视线对焦时间是否满足大于或等于预设时长，判断被观察物是否属于用户能够清楚观察的对象。
在本实施例中，当用户长时间观察或对焦于某个被观察物，说明用户可能希望对其进行仔细查看，或者可能由于无法看清而希望努力对视线进行对焦，均表明用户希望对当前的被观察物进行细节上的观察，所以需要进行放大展示。
4、基于信息元素的判断
作为又一示例性实施方式，可以根据被观察物中是否包含预设类型的信息元素，判断被观察物是否属于用户能够清楚观察的对象。
举例而言，比如智能眼镜确定了当前的被观察物后，可以进一步识别该被观察物中包含的信息元素，比如是否包含字符、图标(比如商品的Logo)等，若包含则判定其无法被用户清楚观察，需要放大展示。
需要说明的是：
以上介绍了四种方式，而实际上可以应用其中任意一种或多种的组合，从而对被观察物是否能够被用户清楚观察进行准确判断。其中，当同时采用多种方式的组合时，作为一示例性实施例，可以在其中至少一种方式的判断结果为被观察物无法被用户清楚观察的情况下，判定被观察物无法被用户清楚观察；或者，作为另一示例性实施例，可以在采用的所有方式的判断结果均为被观察物无法被用户清楚观察的情况下，判定被观察物无法被用户清楚观察。
四、对被观察物的放大展示
作为一示例性实施例，可以显示一预设规格的展示区域，并将所述被观察物的图像进行放大展示于所述展示区域内。
假定图7为用户视野范围在用户眼睛中的成像示意图，则图8可以为智能眼镜对被观察物B进行放大展示的示意图。如图8所示，可以在图像内显示一展示区域，该展示区域可以为图8所示的“放大镜”或其他形态，本公开并不对此进行限制。由图8可见，通过对被观察物B的放大展示，可以看到画中人的左侧裙摆上的点状花纹，而用户则无法直接观察到类似的细节。
用户可以控制对被观察物的缩放比例，比如用户向智能眼镜发出放大比例的指令后，得到图9所示的示意图。其中，图9同时对展示区域和该展示区域内属于被观察物B的展示内容进行了放大；当然，也可以仅对展示区域内的展示内容进行放大，但展示区域的增大可以确保足够大的展示面积，以方便用户的观察。
进一步地，智能眼镜可以监测用户的视线移动事件，并根据该视线移动事件对展示区域进行移动，且根据对被观察物的图像的放大比例，更新放大展示于展示区域内的图像。比如图10所示，当用户的视线向右侧移动时，展示区域随之发生移动，且位于展示区域内的展示内容也产生相应的更新，譬如由图9所示的“左侧裙摆”更新为图10所示的“右侧裙摆”。
当然，如果用户的视线移动出被观察物的范围，则应当取消对被观察物的图像的放大展示，因为此处的“被观察物”已经发生了变化，需要重新按照上述实施例来确定新的被观察物，并确定是否需要对其进行放大展示。
需要说明的是：图8-10所示的“放大镜”形式的“展示区域”并非必须，智能眼镜可以仅对展示内容进行放大和展示，则智能眼镜的整个显示屏均作为此处的“展示区域”。
