本发明实施例提供了一种在拍摄过程中的省电装置,包括处理器和程序存储设备,请参阅图1,该装置包括检测单元101、控制单元102、计时单元103、设置单元104及感应单元105。
检测单元101,适用于检测拍摄装置是否进入拍摄状态。
控制单元102,适用于在该检测单元判断拍摄装置进入拍摄状态时,控制预览屏幕在开启状态及关闭状态之间进行切换。
具体地,可以通过如下的方式控制预览屏幕在开启状态及关闭状态之间进行切换:
当预览屏幕处于开启状态时,由计时单元103对预览屏幕的开启时间进行计时,当计时单元103对开启时间的计时达到预设的第一阀值时,由控制单元102关闭预览屏幕;当预览屏幕处于关闭状态时,计时单元103开始对预览屏幕的关闭时间进行计时,当计时单元103对关闭时间的计时达到预设的第二阀值时,由控制单元102开启预览屏幕。
具体地,设置单元104对预设的第一阀值与第二阀值的设置可以通过根据用户的操作进行,也可以直接采用系统的默认值。实际应用中,第一阀值可以设置为10分钟,第二阀值可以设置为1分钟。
感应单元105,适用于在该预览屏幕处于关闭状态时,在该预览屏幕前预设的距离内对用户进行感应,此时所述控制单元102,还适用于在该感应单元感应到用户时,开启该预览屏幕。
具体地,感应单元可以通过设置距离感应器或红外线感应器实现对用户的感应。这样可以使用户即使在预览屏幕处于关闭态时,也可以随时查看当前的拍摄效果。
在实际应用中,当控制单元102在感应单元的触发下开启了预览屏幕之 后,也可以在感应单元105感应到用户离开了预览屏幕时(即在上述预设的距离内感应不到用户)关闭预览屏幕。
本实施例的拍摄过程中的省电装置,能够对拍摄装置的拍摄状态进行判断,并在判断拍摄装置进入了拍摄状态时,利用控制单元控制预览屏幕在开启状态及关闭状态之间进行切换,避免了因为预览屏幕长时间开启引起的电量损耗,从而达到在拍摄过程中的省电目的。并且,该装置设有计时单元,每当关闭预览屏幕一段时间之后,便将预览屏幕开启一段时间,使得用户能够查看拍摄的效果。另外,该装置还设有感应单元,当感应单元感应到用户靠近预览屏幕时,控制单元就便开启预览屏幕,使用户可以随时查看但前的拍摄效果。
在上述装置实施例的基础上,本发明实施例还提供了一种拍摄过程中的省电方法。请参阅图2,方法流程包括:
S201、检测拍摄装置是否进入拍摄状态。
S202、若是,则在拍摄的过程控制预览屏幕在开启状态及关闭状态之间进行切换。
具体地,该步骤可通过如下方式实现:
当该预览屏幕处于开启状态时,对开启时间进行计时,当该开启时间达到预设的第一阀值时,关闭该预览屏幕;
当该预览屏幕处于关闭状态时,对关闭时间进行计时,当该关闭时间达到预设的第二阀值时,关闭该预览屏幕。
实际应用中,该第一阀值与第二阀值可以根据用户的操作进行设置,也可以采用系统默认的值。
具体地,该方法还包括:
当该预览屏幕处于关闭状态时,在该预览屏幕前预设的距离内对用户进行感应;
若在该预设的距离内感应到用户,则开启该预览屏幕。
实际应用中,也可以在开启了该预览屏幕之后,继续对用户进行感应,如果在上述预设的距离内未感应到用户,则关闭预览屏幕。
本实施例的拍摄过程中的省电方法,能够对拍摄装置的拍摄状态进行判断,并在判断拍摄装置进入了拍摄状态时,控制预览屏幕在开启状态及关闭状态之间进行切换,避免了因为预览屏幕长时间开启引起的电量损耗,从而达到在拍摄过程中的省电目的。并且,每当关闭预览屏幕一段时间之后,便将预览屏幕开启一段时间,使得用户能够查看拍摄的效果。另外,还可以在预览屏幕前预设的距离内对用户进行感应,并在感应到用户靠近预览屏幕时,开启预览屏幕,使用户可以随时查看但前的拍摄效果。
在上述两个实施例的基础上,本发明实施例还提供了另一种在拍摄过程中省电的方法。本实施例中,以星轨模式为例对本发明进行说明,并采用第一计时器对预览屏幕的开启状态进行计时,采用第二计时器对预览屏幕的关闭状态进行计时,请参阅图3,方法流程包括:
S301、根据用户的操作对星轨模式的预览选项进行设置。
具体地,预览选项包括预览屏幕保持开启状态的时间的第一阀值,以及保持关闭状态的时间的第二阀值。
实际应用中,也可以对其他指定的拍摄模式的预览选项进行设置。
S302、当用户开启摄像头时,开启预览屏幕,并检测当前的拍摄模式是否为星轨模式,若是,执行步骤S303。
S303、判断摄像头是否开始拍摄,若是,执行S304。
S304、开启第一计时器。
S305、判断第一计时器的时间值是否达到第一阀值,若达到第一阀值,将第一计时器清零,并执行步骤S306。
S306、关闭预览屏幕,并开启第二计时器。
S307、判断第二计时器的时间值是否达到第二阀值,若是执行步骤S308,否则执行步骤S309。
S308、将第二计时器清零,开启预览屏幕,并执行步骤S304。
S309、开启距离感应器,并在预览屏幕前预设的距离内对用户进行感应,若感应到用户,关闭距离感应器,并执行步骤S308。
本步骤中,距离感应器仅在预览屏幕被关闭的时候开启,能够进一步控制因距离感应器的开启产生的耗电,以便最大程度上实现省电的目的。
本实施例的拍摄过程中的省电方法,能够在对指定拍摄模式(本实施例中为星轨模式)的预览选项进行设置,然后当前的拍摄模式进行判断,并在判断当前的拍摄模式为星轨模式时,控制预览屏幕在开启状态及关闭状态之间进行切换,避免了因为预览屏幕长时间开启引起的电量损耗,从而达到在拍摄过程中的省电目的。并且,每当关闭预览屏幕一段时间之后,便将预览屏幕开启一段时间,使得用户能够查看拍摄的效果。另外,还可以在预览屏幕前预设的距离内对用户进行感应,并在感应到用户靠近预览屏幕时,开启预览屏幕,使用户可以随时查看但前的拍摄效果。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件完成,所述程序可以存储于计算机可读存储介质中,如只读存储器、磁盘或光盘等。可选地,上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地,上述实施例中的各模块/单元可以采用硬件的形式实现,也可以采用软件功能模块的形式实现。本发明不限制于任何特定形式的硬件和软件的结合。
当然,本发明还可有其他多种实施例,在不背离本发明精神及其实质的情况下,熟悉本领域的技术人员当可根据本发明作出各种相应的改变和变形,但这些相应的改变和变形都应属于本发明的权利要求的保护范围。
工业实用性
