示例性的,若转动装置当前能够调节的目标拍摄参数为跟焦参数,则获取拍摄设备的跟焦参数的当前数值,而若转动装置当前能够调节的目标拍摄参数为变焦参数,则获取拍摄设备的变焦参数的当前数值,而若转动装置当前能够调节的目标拍摄参数为曝光参数,则获取拍摄设备的曝光参数的当前数值。
S102、若所述目标拍摄参数的当前数值不处于预设数值范围内,则增大所述转动装置的转动阻尼。
其中,预设数值范围与目标拍摄参数的极限值,即最小数值和最大数值有关。具体为:该预设数值范围的第一端点值大于或等于目标拍摄参数的最小数值,预设数值范围的第二端点值小于或等于目标拍摄参数的最大数值。可以理解的是,不同类型的目标拍摄参数的预设数值范围不同,例如,跟焦参数的预设数值范围与变焦参数的预设数值范围不同,变焦参数的预设数值范围与曝光参数的预设数值范围不同。

S1022、根据所述反馈控制量和预设反馈系数,增大所述转动装置的转动阻尼。
其中,预设反馈系数与目标拍摄参数的取值范围相关,目标拍摄参数的取值范围越大,则预设反馈系数越小,目标拍摄参数的取值范围越小,则预设反馈系数越大,反馈控制量与转动装置的转动阻尼呈正相关关系,即反馈控制量越大,则转动装置的转动阻尼越大,反馈控制量越小,则转动装置的转动阻尼越小。不同的拍摄设备可能具有不同的目标拍摄参数的取值范围,通过根据反馈控制量和预设反馈系数,增大所述转动装置的转动阻尼,可以使得不同的拍摄设备能够对应于归一化的转动装置的操作手感。
在一实施例中,该转动装置与阻尼调节装置连接,根据反馈控制量和预设反馈系数,增大转动装置的转动阻尼的方式可以为:根据反馈控制量和预设反馈系数,确定该阻尼调节装置的运行参数,即确定反馈控制量和预设反馈系数的乘积,并将反馈控制量和预设反馈系数的乘积作为该阻尼调节装置的运行参数;控制该阻尼调节装置按照该运行参数运行,以增大转动装置的转动阻尼。通过反馈控制量和预设反馈系数可以将反馈控制量转化为阻尼调节装置的运行参数,从而使得阻尼调节装置基于该运行参数运行,以增大转动装置的转动阻尼。
在一实施例中,获取拍摄设备的目标拍摄设备的当前数值;若该目标拍摄参数的当前数值不处于预设数值范围内,且当前数值未达到目标拍摄参数的极限值,则增大转动装置的转动阻尼。通过在该目标拍摄参数的当前数值不处于预设数值范围内,且当前数值未达到目标拍摄参数的极限值时,增大转动装置的转动阻尼,以反馈目标拍摄参数的当前数值与极限值之间的关系,便于用户操作转动装置,能够在目标拍摄参数的当前数值达到极限值时,停止对转动装 置进行转动,可以防止拍摄设备损坏,提高用户体验。
在一实施例中,获取拍摄设备的目标拍摄设备的当前数值;若该目标拍摄参数的当前数值不处于预设数值范围内,且目标拍摄参数的当前数值达到目标拍摄参数的极限值,则锁定转动装置,其中,锁定后的转动装置不随着用户的操作而转动。在当前数值达到目标拍摄参数的极限值时,锁定转动装置,使得转动装置不随着用户的操作而转动,能够防止拍摄设备损坏,提高用户体验。
上述实施例提供的转动装置的操作反馈方法,通过获取拍摄设备的目标拍摄参数的当前数值,若目标拍摄参数的当前数值不处于预设数值范围内,则增大转动装置的转动阻尼,使得用户对该转动装置进行转动时,转动装置能够反馈拍摄参数的当前数值与极限值之间的关系,便于用户感知拍摄设备的拍摄参数是否达到极限值,极大地提高了用户体验。
