Description

循环拍照系统及其方法 技术领域
本发明涉及拍照方法，尤其涉及一种循环拍照系统及其方法。
背景技术
现有拍摄技术在抓拍某一精彩瞬间的时候，目前大致有以下两种方式：第一种是人工等待操作快门的方式。这种方式的弊端在于(1)拍摄过程耗费人工精力，(2)结果很难抓拍精准。第二种是用普通的照片连拍方式。这种方式的弊端在于：(1)随着连拍时间和频率的增加，保存的照片数量会很大，再加上目前单张高分辨率相片本身占用存储空间就很大，因此每次连拍将占用大量的存储空间，(2)保存的大量照片中大部分照片是没有实际用处，在挑选合格照片是也费时费力。
因此，需要一种改进的拍照方法来提升用户体验度，同时节省照片存储空间。
发明内容
为了解决上述问题，本发明提供一种循环拍照系统，其特征在于，所述循环拍照系统包括：拍照单元，用于根据用户操作而进行循环连拍；存储单元，连接于所述拍照单元，用于存储所拍摄的照片；设置单元，用于设置保存时间段和拍摄频率；以及循环覆盖单元，连接于所述设置单元和所述存储单元，用于当已拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。
优选地，当已拍摄时间未超过所设置的保存时间段时，则所述存储单元不断写入所述拍照单元拍摄到的照片。
优选地，所述拍摄频率为5张/秒或10张/秒，并且所述保存时间段为3秒。
优选地，所述存储单元单次循环连拍的保存的照片张数小于或等于所述拍摄频率与所述保存时间段的乘积。
本发明实施例另提供一种循环拍照方法，其特征在于，所述循环拍照方法包括：设置保存时间段和拍摄频率；根据用户操作而启动循环连拍；存储所拍摄的照片；当已拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。
优选地，循环拍照方法还包括：当已拍摄时间未超过所设置的保存时间段时，则不断存储拍摄到的照片。
优选地，所述拍摄频率为5张/秒或10张/秒，并且所述保存时间段为3秒。
优选地，所述单次循环连拍的保存的照片张数小于或等于所述拍摄频率与所述保存时间段的乘积。
本发明的上述实施例能够通过在启动连拍后按照需要的拍摄频率进行拍摄，并保存拍摄停止前所设置的保存时间段内拍摄的照片，当拍摄时间未超过所设置的保存时间段时，则保存当前拍摄的照片；当拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。这样就能在不占用巨大存储空间的情况下，保存到合格的照片。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。
图1是根据本发明实施例的一种循环拍照系统的结构框图。
图2是根据本发明实施例的一种循环拍照方法的流程图。
图3是根据本发明实施例的一种循环拍照时间轴的示意图。
具体实施方式
下面结合附图和具体实施方式对本发明的技术方案作进一步更详细的描述。显然，所描述的实施例仅仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例，都应属于本发明保护的范围。
图1是根据本发明实施例的一种循环拍照系统100的结构框图。所述循环 拍照系统100可包括：
拍照单元102，用于根据用户操作而进行循环连拍；
存储单元104，连接于所述拍照单元102，用于存储所拍摄的照片；
设置单元108，用于设置保存时间段和拍摄频率；以及
循环覆盖单元106，连接于所述设置单元108和所述存储单元104，用于当已拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。
优选地，所述拍摄频率可以是5张/秒或10张/秒，并且所述保存时间段为3秒。即，保存时间段为停止循环连拍至往前3秒。请注意，本领域技术人员在阅读本申请后可容易想到：还可采用其它合适的拍摄频率和保存时间段，其只是示例性而并非本发明的限制。
当已拍摄时间(从启动连拍作为时间点开始计算)未超过所设置的保存时间段时，则所述存储单元104可不断写入所述拍照单元拍摄到的照片(例如，以5张/秒或10张/秒的拍摄频率)。所述存储单元104单次循环连拍的保存的照片张数小于或等于所述拍摄频率与所述保存时间段的乘积。
结合图3的循环拍照时间轴的示意图来理解。在拍摄时间轴上，响应于用户的操作，产生启动连拍时间点和停止连拍时间点。
对于情况(1)，如果拍摄时间比保存时间段短(小于或等于)，则无需覆盖历史照片，此时：
拍摄时间＝停止连拍时间点-启动连拍时间点
保存时间段的起点＝启动连拍时间点
保存时间段的终点＝停止连拍时间点
保存照片数量＝(停止连拍时间点-启动连拍时间点)*拍摄频率
对于情况(2)，如果拍摄时间比保存时间段长(大于)，则需覆盖历史照片
如图3所示，当连拍拍摄时间过长时，为节省存储空间，可只保存在停止连拍时间点前所设置的保存时间段内拍摄的照片。
当拍摄时间未超过所设置的保存时间段时，则保存当前拍摄的照片；当拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片(如图中斜线方框所示的被覆盖部分)。这样就能在不占用巨大存储空间的情况下，保存到合格的照片。例如，在5张/秒的拍摄频 率情况下，当拍摄时间超过所设置的保存时间段2秒时，新拍摄的十张照片将按照时间顺序依次覆盖在当前保存时间段内保存时间最老(即，最早保存)的十张照片。
此时：
拍摄时间＝停止连拍时间点-启动连拍时间点
保存时间段的起点＝停止连拍时间点-保存时间段
保存时间段的终点＝停止连拍时间点
保存照片数量＝所设置的保存时间段*拍摄频率
图2是根据本发明实施例的一种循环拍照方法200的流程图。所述循环拍照方法可包括：
步骤202：设置保存时间段和拍摄频率；
步骤204：根据用户操作而启动循环连拍；
步骤206：当已拍摄时间未超过所设置的保存时间段时，则不断存储拍摄到的照片；
步骤208：当已拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。
优选地，循环拍照方法200还可包括：当已拍摄时间未超过所设置的保存时间段时，则不断存储拍摄到的照片。优选地，所述拍摄频率为5张/秒或10张/秒，并且所述保存时间段为3秒。请注意，本领域技术人员在阅读本申请后可容易想到：还可采用其它合适的拍摄频率和保存时间段，其只是示例性而并非本发明的限制。
优选地，所述单次循环连拍的保存的照片张数小于或等于所述拍摄频率与所述保存时间段的乘积。
有利地，本发明的上述实施例能够通过在启动连拍后按照需要的拍摄频率进行拍摄，并保存拍摄停止前所设置的保存时间段内拍摄的照片，当拍摄时间未超过所设置的保存时间段时，则保存当前拍摄的照片；当拍摄时间超过所设置的保存时间段时，则用新拍摄的每张照片覆盖在当前保存时间段内保存时间最老的照片。这样就能在不占用巨大存储空间的情况下，保存到合格的照片。
需要说明的是，通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到本发明可借助软件加必需的硬件平台的方式来实现，当然也可以全部 通过硬件来实施。基于这样的理解，本发明的技术方案对背景技术做出贡献的全部或者部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本发明各个实施例或者实施例的某些部分所述的方法。
以上所揭露的仅为本发明实施例中的较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
