Description

拍摄方法、装置和存储介质 技术领域
本发明涉及摄像技术领域，尤其是涉及一种拍摄方法、装置和计算机存储介质。
背景技术
星空拍摄，是指利用相机拍摄星云照片或星轨照片的一种拍摄体验，深受天文爱好者的欢迎。由于星光比较微弱，需要长时间曝光才能得到较好的拍摄效果。目前的天文爱好者多采用单反相机进行星空拍摄，需对拍摄参数进行手动调节，操作过程比较繁琐，对摄影者的专业知识要求较高。但是，很多摄影用户并非专业用户，因此无法进行星空拍摄或无法获得较佳的拍摄效果。
针对上述问题，现有的技术方案是在数码相机、手机等拍摄装置中预先设置专门针对星空拍摄的拍摄参数，当用户进行星空拍摄时，则直接调用该拍摄参数进行拍摄，从而使得非专业用户也能进行星空拍摄。
然而，预设的拍摄参数是固定不变的，而拍摄时间、地点和天气等拍摄环境则变化多端，一组拍摄参数显然不能匹配所有的拍摄环境，因此无法获得较佳的拍摄效果。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的拍摄方法主要应用于星空拍摄，星空拍摄主要包括星云拍摄、星轨拍摄等，其中星云拍摄主要用于在夜间拍摄星星，其特点是环境光较弱，需较长的曝光时间，因此也可以应用于类似的应用场景；而星轨拍摄用于拍摄星星的运动轨迹，而运动轨迹的形成，是由拍摄者和拍摄目标之间的相对运动所致，因此同理也可以应用于类似的应用场景。在开始星空拍摄时或星空拍摄过程中，获取环境信息，根据环境信息调整拍摄参数，最后根据适合当前环境的拍摄参数进行拍摄，就能拍摄出效果更好的星空摄影作品。对应的拍摄作品如星轨照片或视频、星云照片或视频等。其中，环境信息包括时间信息、天气信息、和/或地理位置信息等。以 下通过具体实施例进行详细说明，比如，以不同的环境信息下进行星空拍摄来举例。
参见图1，提出本发明的拍摄方法第一实施例，所述拍摄方法包括以下步骤：
步骤S101：获取时间信息；
拍摄装置进入星空拍摄模式后，立即获取拍摄装置上的时间信息或通过网络获取时间信息；或者，不以拍摄装置是否进入星空拍摄模式为前提，拍摄装置会定期或者不定期地获取时间信息。本实施例的环境信息为时间信息，该时间信息至少包括日期信息，还可以包括时刻信息。其中，可选地，日期信息为中国农历日期信息。
步骤S102：根据时间信息获取当前的月相信息；
每个月农历初一到十五，再到初一，月相有规律的发生变化。同时，一年十二个月，每个月的月相也在发生变化。
可选地，用户事先在拍摄装置中选择地理位置，拍摄装置中可以预先存储不同地理位置下时间信息与月相信息的对应关系，拍摄装置根据时间信息以及前述对应关系则可以获得当前的月相信息，该月相信息即月亮的阴晴圆缺。或者可选地，拍摄装置预先存储或者预置有或通过网络获取时间信息与月相信息的对应关系，根据时间信息以及前述对应关系则可以获得当前的月相信息。
进一步地，即使是在同一个晚上，不同时刻的月相也不尽相同，因此还可以进一步通过时刻信息来获取更精确的月相信息如某个时刻的月相信息。
步骤S103：根据月相信息调整拍摄参数；
所述拍摄参数主要包括感光度(ISO)、曝光时间等曝光参数。当月相信息表明当前月亮为满月时，说明星空比较明亮，则调低感光度，减少曝 光时间，防止过曝。当月相信息表明当前月亮为残月时，说明星空较暗，则调高感光度，增加曝光时间，防止曝光不足。
当然，此处仅为举例。可选地，月相信息所对应的星空亮度不同，则拍摄参数所包括的曝光参数也不同。
或者可选地，月相信息所对应的亮度好的星空背景，相比亮度差的星空背景，拍摄参数所包括的感光度更低和/或曝光时间更短。
步骤S104：根据调整后的拍摄参数进行拍摄；
根据当前环境调整获得的拍摄参数，与当前环境更加匹配，此时拍摄出的照片的效果将更好。从而，用户在不同日期甚至不同时刻进行星空拍摄时，拍摄装置都能匹配出最符合当时环境的拍摄参数，拍摄出效果最佳的照片。
参见图2，提出本发明的拍摄方法第二实施例，所述拍摄方法包括以下步骤：
步骤S201：获取天气信息；
本实施例的环境信息为天气信息，拍摄装置通过网络获取当天的天气预报信息，根据天气预报信息获取当前的天气信息。
步骤S202：根据天气信息获取星空的阴晴信息或/和空气中的颗粒物信息；
阴晴信息表明当前的星空是晴朗无云还是阴沉多云。空气中的颗粒物信息，是指气象站提供的空气中颗粒物的检测数据，包括颗粒物的浓度、大小等。
步骤S203：根据阴晴信息或/和空气中的颗粒物信息调整拍摄参数；
如果当前星空晴朗无云，说明星空比较明亮，则调低感光度，减少曝光时间，防止过曝。如果当前星空阴沉多云，说明星空较暗，则调高感光度，增加曝光时间，防止曝光不足。此外，还可以对色温参数进行相应调 整。星空越亮，颗粒物浓度越大、颗粒物粒径越小，对月光的散射越强，星空就越亮。
步骤S204：根据调整后的拍摄参数进行拍摄；
从而，用户在不同的天气状态下进行星空拍摄时，拍摄装置都能匹配出最符合当时环境的拍摄参数，拍摄出效果最佳的照片。
参见图3，提出本发明的拍摄方法第三实施例，所述拍摄方法包括以下步骤：
步骤S301：获取地理位置信息；
本实施例的环境信息为地理位置信息，拍摄装置通过网络或GPS获取当前的地理位置信息。地理位置信息包括经纬度信息、城乡信息、海拔高度信息等。
步骤S302：根据地理位置信息获取当前环境的光照信息；
所述光照信息即当前环境的光照强度。具体的，若地理位置信息显示当前用户位于城市，考虑到城市霓虹灯的影响，则说明当前环境的光照较强，并且离市中心越近当前环境的光照越强；若地理位置信息显示当前用户远离城市，如位于乡村、草原、森林等偏远地区，则说明当前环境的光照较弱。
步骤S303：根据当前环境的光照信息调整拍摄参数；
如果当前环境的光照较强，则会影响拍摄背景，增强星空的亮度，拍摄装置则调低感光度，减少曝光时间，防止过曝。如果当前环境的光照较弱，则可调高感光度，增加曝光时间，防止曝光不足。
步骤S304：根据调整后的拍摄参数进行拍摄；
从而，用户在不同的地点进行星空拍摄时，拍摄装置都能匹配出最符合当时的环境的拍摄参数，拍摄出效果最佳的照片。
参见图4，提出本发明的拍摄方法第四实施例，所述拍摄方法包括以下 步骤：
步骤S401：获取时间信息和天气信息；
本实施例中拍摄装置同时获取时间信息和天气信息两种环境信息。其中，时间信息至少包括日期信息，还可以包括时刻信息。拍摄装置直接获取拍摄装置上的时间信息或通过网络获取时间信息，同时通过网络获取天气预报信息，根据天气预报信息获取当前的天气信息。
步骤S402：根据时间信息获取当前的月相信息，根据天气信息获取阴晴信息或/和空气中的颗粒物信息；
其中，空气中的颗粒物信息，是指气象站提供的空气中颗粒物的检测数据，包括颗粒物的浓度、大小等。
步骤S403：根据月相信息，以及阴晴信息或/和颗粒物信息调整拍摄参数；
月亮越圆星空亮度就越强，星空越晴朗少云星空就越亮，颗粒物浓度越大、颗粒物粒径越小，对月光的散射越强，星空就越亮。拍摄装置综合前述两个或三个信息对拍摄参数进行调整。
步骤S404：根据调整后的拍摄参数进行拍摄；
从而，用户不同时间和不同的天气状况下进行星空拍摄时，拍摄装置都能匹配出最符合当时的环境的拍摄参数，拍摄出效果最佳的照片。
参见图5，提出本发明的拍摄方法第五实施例，所述拍摄方法包括以下步骤：
步骤S501：获取时间信息、天气信息和地理位置信息；
本实施例中拍摄装置同时获取时间信息、天气信息和地理位置信息三种环境信息。其中，时间信息至少包括日期信息，还可以包括时刻信息；地理位置信息包括经纬度信息、城乡信息、海拔高度信息等。
拍摄装置直接获取拍摄装置上的时间信息或通过网络获取时间信息， 同时通过网络获取天气预报信息，根据天气预报信息获取当前的天气信息，通过网络或GPS获取地理位置信息。
步骤S502：根据时间信息和地理位置信息获取当前的月相信息，根据天气信息获取阴晴信息或/和空气中的颗粒物信息；
即使在同一时刻，不同地理位置(处于不同的经纬度)所观察到的月相也不尽相同。本实施例中，拍摄装置自动获取用户当前的地理位置信息，无需用户事先进行手动设置(避免用户移动后忘记更改地理位置)，然后综合时间和地理位置信息，获取更加准确的月相信息。
步骤S503：根据月相信息，以及阴晴信息或/和颗粒物信息调整拍摄参数；
具体的，拍摄装置根据当前时间和所在地理位置，计算出能观察到的月亮面积，进而估算出月亮的亮度。然后，根据气象站提供的空气中颗粒物的检测数据，估计出星空环境光的亮度。进一步还可根据当前星空的阴晴情况获取更精确的环境光亮度信息，最后根据环境光的亮度信息来调节拍摄参数。若环境光越亮，则调低感光度，减少曝光时间，防止过曝。若环境光越弱，则可调高感光度，增加曝光时间，防止曝光不足。
步骤S504：根据调整后的拍摄参数进行拍摄；
从而，用户在不同时间、不同地点和不同的天气状况下进行星空拍摄时，拍摄装置都能匹配出最符合当时的环境的拍摄参数，拍摄出效果最佳的照片。
参见图6，提出本发明的拍摄方法第六实施例，所述拍摄方法包括以下步骤：
步骤S601：获取环境信息；
环境信息包括以下至少一种：时间信息、天气信息、地理位置信息等。
步骤S602：根据环境信息调整拍摄参数；
步骤S603：提示用户已进行参数调整；
具体的，拍摄装置可向用户推送语音或文字信息，提示用户根据某某环境信息进行了参数调整，说明调整后的拍摄参数为多少，或者详细说明对每一项参数做了怎样的调整。
步骤S604：根据调整后的拍摄参数进行拍摄；
其中，步骤S603和S604也可以同步进行。
从而，调整参数后还对用户进行提示，使得用户对整个拍摄过程了然于胸，提高了智能化和人性化程度。
参见图7，提出本发明的拍摄方法第七实施例，所述拍摄方法包括以下步骤：
步骤S701：获取环境信息；
步骤S702：询问是否需要根据环境信息进行参数调整；
本实施例的拍摄装置在获取环境信息后，不立即进行参数调整，而是向用户推送文字或语音通知，询问用户是否需要根据某某环境信息进行参数调整。如果用户选择“否”，则进入步骤S703；如果用户选择“是”，进入步骤S704。
步骤S703：根据当前的拍摄参数进行拍摄；
若用户不同意调整参数，拍摄装置则直接使用当前的拍摄参数进行拍摄，当前的拍摄参数即默认的拍摄参数或前一次拍摄时的拍摄参数。
步骤S704：根据环境信息调整拍摄参数；
若用户同意调整参数，拍摄装置则根据环境信息进行参数调整。
可选地，环境信息所对应的星空亮度不同，则拍摄参数所包括的曝光参数也不同。
或者可选地，根据环境信息获取星空的亮度信息，星空亮度越高，则将拍摄参数中的感光度调得更低或/和曝光时间调得更短。
步骤S705：根据调整后的拍摄参数进行拍摄；
从而，通过事先询问用户，根据用户的选择来决定是否调整参数，一方面尊重了用户的意见，更加人性化；另一方面可以防止拍摄装置误判当前环境而进行不合适宜的参数调整，保证了拍摄效果。
拍摄装置可以在开始星空拍摄时或星空拍摄过程中进行参数调整。对于星云拍摄，拍摄装置可以只在进入星云拍摄模式后，拍摄首张照片时进行拍摄参数调整，在退出星云拍摄模式之前后续拍摄的照片都沿用首张照片所使用的拍摄参数。或者，也可以每隔预设时间进行一次拍摄参数调整。
对于星轨拍摄，由于拍摄时间较长，拍摄装置可以在一次拍摄时进行一次拍摄参数调整，即刚进入星轨拍摄模式时调整参数；拍摄装置也可以在一次拍摄过程中，每隔预设时间(根据时刻信息)进行一次拍摄参数调整。
在某些实施例中，拍摄装置除了自动调整拍摄参数外，还可以提供界面，供用户手动选择拍摄参数。
通过本发明实施例提供的拍摄方法，如果用户自行改变拍摄装置环境信息(如时间信息)，则能相应地调整拍摄参数，达到娱乐化的效果。另外，为了使得拍摄效果不同，可以更换不同的环境信息如时间信息进行拍摄，从而得到效果不同的拍摄结果。
本发明还提供一实施例，在本实施例中，一种拍摄方法包括以下步骤：
S1：拍摄装置内部存储或者接收外部的环境信息与拍摄参数一一对应的对照表(或者环境信息与拍摄参数一一对应的信息)；
S2：获取当前的环境信息，根据环境信息与拍摄参数一一对应的信息，查找与当前的环境信息相互对应的拍摄参数；
S3：根据查到的拍摄参数进行拍摄。
本发明的实施例，拍摄参数可以手动或者可以自动进行调整。且，拍 摄参数的调整可以在拍摄之前就进行调整，或在拍摄过程中进行调整。比如，拍摄装置进行第一时间的曝光时间的慢门拍摄，此时，根据环境信息或者当前的环境信息需要调整曝光时间为第二时间，则将曝光时间从第一时间调整为第二时间。
本发明实施例还提供了一种计算机存储介质，所述计算机存储介质中存储有计算机可执行指令，所述计算机可执行指令用于执行前述的拍摄方法。
参见图8，提出本发明的拍摄装置第一实施例，所述拍摄装置尤其适合用于星空拍摄及其类似的应用场景，其包括获取模块801、调整模块802和拍摄模块803。
获取模块801，配置为：获取环境信息。环境信息包括时间信息、天气信息、地理位置信息等。其中，时间信息至少包括日期信息，还可以包括时刻信息；地理位置信息包括经纬度信息、城乡信息、海拔高度信息等。

调整模块802，配置为：根据环境信息调整拍摄参数，并将调整后的参数信息发送给拍摄模块。
调整模块802可以根据时间信息、天气信息、地理位置信息等环境信息中的任意一种、任意两种或多种的组合，来调整拍摄参数。拍摄参数主要包括感光度(ISO)、曝光时间等曝光参数。可选地，调整模块802根据环境信息获取星空的亮度信息，环境信息所对应的星空亮度不同，则拍摄 参数所包括的曝光参数也不同。可选地，星空亮度越高，调整模块802则将拍摄参数中的感光度调得更低或/和曝光时间调得更短。
当环境信息为时间信息时，调整模块802根据时间信息获取月相信息，根据月相信息调整拍摄参数。具体的，用户事先在拍摄装置中手动选择地理位置，拍摄装置中可预先存储不同地理位置下时间信息与月相信息的对应关系，调整模块802根据时间信息以及预存的时间信息与月相信息的对应关系，获得当前的月相信息，该月相信息即月亮的阴晴圆缺；或者可选地，拍摄装置预先存储或者预置有或通过网络获取时间信息与月相信息的对应关系，调整模块802根据时间信息以及前述对应关系则可以获得当前的月相信息。当月相信息表明当前月亮为满月时，说明星空比较明亮，调整模块802则调低感光度，减少曝光时间，防止过曝。当月相信息表明当前月亮为残月时，说明星空较暗，调整模块802则调高感光度，增加曝光时间，防止曝光不足。当然，此处仅为举例。可选地，月相信息所对应的星空亮度不同，则拍摄参数所包括的曝光参数也不同。或者可选地，月相信息所对应的亮度好的星空背景，相比亮度差的星空背景，拍摄参数所包括的感光度更低和/或曝光时间更短。
当环境信息为天气信息时，调整模块802根据天气信息获取星空的阴晴信息或/和空气中的颗粒物信息，根据该阴晴信息或/和空气中的颗粒物信息调整拍摄参数。具体的，如果当前星空晴朗无云，说明星空比较明亮，调整模块802则调低感光度，减少曝光时间，防止过曝，星空越亮，颗粒物浓度越大、颗粒物粒径越小，对月光的散射越强，星空就越亮。如果当前星空阴沉多云，说明星空较暗，调整模块802则调高感光度，增加曝光时间，防止曝光不足。此外，调整模块802还可以对色温参数进行相应调整。
当环境信息为地理位置信息时，调整模块802根据地理位置信息获取 当前环境的光照信息，根据该光照信息调整拍摄参数，其中光照信息即当前环境的光照强度。具体的，若地理位置信息显示当前用户位于城市，考虑到城市霓虹灯的影响，则说明当前环境的光照较强，并且离市中心越近当前环境的光照越强；若地理位置信息显示当前用户远离城市，如位于乡村、草原、森林等偏远地区，则说明当前环境的光照较弱。如果当前环境的光照较强，则会影响拍摄背景，增强星空的亮度，调整模块802则调低感光度，减少曝光时间，防止过曝。如果当前环境的光照较弱，调整模块802则可调高感光度，增加曝光时间，防止曝光不足。
当环境信息包括时间信息和天气信息时，调整模块802根据时间信息获取月相信息，根据天气信息获取阴晴信息或/和空气中的颗粒物信息，根据月相信息、以及颗粒物信息或/和阴晴信息调整拍摄参数。其中，空气中的颗粒物信息，是指气象站提供的空气中颗粒物的检测数据，包括颗粒物的浓度、大小等。月亮越圆星空亮度就越强，星空越晴朗少云星空就越亮，颗粒物浓度越大、颗粒物粒径越小，对月光的散射越强，星空就越亮。调整模块802综合前述信息对拍摄参数进行调整。
当环境信息包括时间信息、天气信息和地理位置信息时，调整模块802根据时间信息和地理位置信息获取月相信息，根据天气信息获取阴晴信息或/和空气中的颗粒物信，根据月相信息、以及颗粒物信息或/和阴晴信息调整拍摄参数。即使在同一时刻，不同地理位置(处于不同的经纬度)所观察到的月相也不尽相同，本实施例通过获取模块801自动获取用户当前的地理位置信息，无需用户事先进行手动设置(避免用户移动后忘记更改地理位置)，使得调整模块802综合时间和地理位置信息，获取更加准确的月相信息。具体的，调整模块802根据当前时间和所在地理位置，计算出能观察到的月亮面积，进而估算出月亮的亮度。然后，根据气象站提供的空气中颗粒物的检测数据，估计出星空环境光的亮度。进一步还可根据当前星空 的阴晴情况获取更精确的环境光亮度信息。最后根据环境光的亮度信息来调节拍摄参数。若环境光越亮，调整模块802则调低感光度，减少曝光时间，防止过曝。若环境光越弱，调整模块802则可调高感光度，增加曝光时间，防止曝光不足。
拍摄模块803，配置为：根据拍摄参数进行拍摄。

拍摄装置可以在开始星空拍摄时或星空拍摄过程中进行参数调整。
参见图9，提出本发明的拍摄装置第二实施例，本实施例与实施例的区别是增加了一提示模块804，配置为：当调整模块802调整完拍摄参数后，提示用户已进行参数调整。提示模块804可向用户推送语音或文字信息，提示用户根据某某环境信息进行了参数调整，说明调整后的拍摄参数为多少，或者详细说明对每一项参数做了怎样的调整。使得用户对整个拍摄过程了然于胸。
参见图10，提出本发明的拍摄装置第三实施例，本实施例与第一实施例的区别是增加了一询问模块805，配置为：在获取模块801获取环境信息后，调整模块802调整拍摄参数之前，询问用户是否需要根据环境信息进行参数调整；若用户选择“是”，则向调整模块802发送调整指令；若用户选择否，则不发送调整指令。询问模块805可以向用户推送文字或语音通知，询问用户是否需要根据某某环境信息进行参数调整。若用户不同意调整参数，拍摄模块803则直接使用当前的拍摄参数进行拍摄，当前的拍摄参数即默认的拍摄参数或前一次拍摄时的拍摄参数。从而，使得用户可以自主选择是否进行参数调整。
在某些实施例中，拍摄装置除了自动调整拍摄参数外，还可以提供界面，供用户手动选择拍摄参数。
通过本发明实施例提供的拍摄装置，如果用户自行改变拍摄装置环境信息(如时间信息)，则能相应地调整拍摄参数，达到娱乐化的效果。另外，为了使得拍摄效果不同，可以更换不同的环境信息如时间信息进行拍摄，从而得到效果不同的拍摄结果。
