Description

[根据细则26改正 10.10.2023]控制方法、镜头控制装置、镜头驱动器和跟焦控制系统 技术领域
[根据细则26改正 10.10.2023]
本发明涉及摄影辅助设备技术领域,特别涉及一种应用于镜头控制装置的控制方法、应用于镜头驱动器的控制方法、镜头控制装置、镜头驱动器和跟焦控制系统。
[根据细则26改正 10.10.2023]
本发明涉及摄影辅助设备技术领域,特别涉及一种应用于镜头控制装置的控制方法、应用于镜头驱动器的控制方法、镜头控制装置、镜头驱动器和跟焦控制系统。

本发明涉及摄影辅助设备技术领域,特别涉及一种应用于镜头控制装置的控制方法、应用于镜头驱动器的控制方法、镜头控制装置、镜头驱动器和跟焦控制系统。
背景技术
[根据细则26改正 10.10.2023]
在拍摄过程中,摄影设备(例如包括摄像机或照相机的设备)需要适时调节镜头焦点、焦距以适应画面构图,而在拍摄过程中,摄影设备通常需要根据拍摄画面需求进行移动,且大多数摄影设备通常重量很大,故在拍摄过程中,通过人为操作旋转镜头进行变焦比较困难。目前通常采用的方案为,在镜头旁安装用于驱动镜头焦圈旋转的镜头驱动器,并通过调节与镜头驱动器有线或无线连接的镜头控制装置(跟焦控制器)来实现变焦和对焦。
[根据细则26改正 10.10.2023]
由于摄影设备的镜头的变焦调节和对焦调节都需要镜头驱动器进行驱动,有的摄影设备上还需要镜头驱动器来调节镜头的滤镜透光率,因此,摄影设备上通常需要安装至少两个镜头驱动器。目前通常是采用多个镜头控制装置来分别控制各个镜头驱动器,每个镜头控制装置与对应的镜头驱动器采用同频道通讯,且各个镜头控制装置分别采用不同的频道,由于频道的数量有限,镜头控制装置和镜头驱动器的通讯频道内,会有其它设备的通讯信号,容易对镜头控制装置与镜头驱动器之间的通讯造成干扰,影响对镜头的精确控制。

具体实施方式
[根据细则26改正 10.10.2023]
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,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前提下所获得的所有其他实施例,都属于本发明保护的范围。
[根据细则26改正 10.10.2023]
本发明提出一种控制方法,应用于摄影设备的镜头控制装置,镜头控制装置包括至少一个调节件。
[根据细则26改正 10.10.2023]
其中,摄影设备例如为摄像机、照相机等,镜头控制装置用于控制摄影设备的镜头驱动器工作,镜头驱动器用于驱动摄影设备的镜头的变焦环、对焦环或滤镜调节轮,以对镜头进行变焦调节、对焦调节或透光率调节。其中,调节件为镜头控制装置的活动件,调节件可为镜头控制装置上转动设置转动件,例如,旋钮、转轮、转轴、转盘,调节件也可以是镜头控制装置上滑动设置的滑动件,例如滑块。
[根据细则26改正 10.10.2023]
参阅图1,图1是本发明一实施例中的控制方法的流程示意图。
[根据细则26改正 10.10.2023]
在本实施例中,该控制方法包括:
[根据细则26改正 10.10.2023]
步骤S10,在检测到任意一个调节件的位置数据变化时,获取该调节件当前的位置数据和该调节件对应的匹配标识;
[根据细则26改正 10.10.2023]
本实施例的实施终端可为镜头控制装置的控制器,控制器中存储有各个调节件对应的匹配标识,匹配标识可为编号(例如,01、02、03),也可为字母(例如,A、B、C),还可为字符串等各类标识。镜头控制装置具有检测其调节件位置数据的检测装置(例如,传感器装置),检测装置会将检测的位置数据反馈给控制器。当用户操作调节件运动(转动或滑动)时,控制器会根据检测装置反馈的位置数据可确定该调节件的位置数据发生变化(例如通过将本次接收到的位置数据与上一次接收到的位置数据比对确定),此时,控制器则获取用户转动或滑动的那个调节件当前的位置数据备,并获取该调节件所对应的匹配标识。其中,调节件为转动设置的转动件时,位置数据为角度位置;调节件为滑动件时,位置数据可为距离起点的位移量。在本发明的下述实施例中,以调节件为转动件,以及位置数据为角度位置为例,对本发明进行阐述。
[根据细则26改正 10.10.2023]
步骤S20,根据获取的位置数据和匹配标识生成相应的调节信号进行无线发送。
[根据细则26改正 10.10.2023]
控制器在获取到该调节件当前的位置数据和对应的匹配标识后,则根据获取的位置数据和匹配标识进行预设的信号转换处理,以生成相应的包含有该匹配标识的调节信号,并将该调节信号通过无线方式发送。其中,调节信号中包含匹配标识,匹配标识用于供接收调节信号的镜头驱动器进行匹配验证。在调节信号无线发送出去后,与镜头控制装置无线连接的各个镜头驱动器都能够接收到该调节信号,镜头驱动器接收到调节信号后,需要先对验证该调节信号的匹配标识,只有在验证通过时才会根据该调节信号进行相应的驱动工作,即该调节信号只让与用户操作的那个调节件所对应的镜头驱动器执行。需要说明的是,镜头控制装置的调节件可以与镜头驱动器一一对应,即每个调节件控制调节对应的镜头驱动器,镜头控制装置的调节件也可以对应多个镜头驱动器,即一个调节件同步控制多个镜头驱动器。
[根据细则26改正 10.10.2023]
本实施例的镜头控制装置的控制方法,在检测到任一调节件的位置数据变化时(即用户调节任一调节件时),获取该调节件当前位置数据和对应的匹配标识,以生成包含该匹配标识的调节信号进行无线发送。由于在无线发送的调节信号中加入了调节件对应的匹配标识,使镜头驱动器在接收到调节信号时,需要先验证调节信号中的匹配标识,并只在匹配标识验证通过后,才根据调节信号执行相应的驱动调节。如此,镜头控制装置与镜头驱动器的通讯频道内即使有其它无线设备的信号,镜头驱动器也不会出现误执行其它设备发送的无线信号的情况,有效防止镜头控制装置与镜头驱动器之间的通讯信号被干扰,保证对镜头的精确控制。
[根据细则26改正 10.10.2023]
参阅图2,在本实施例中,镜头控制装置具有用于与镜头驱动器有线连接的数据信号接口(例如type-c接口),数据信号接口可通过信号线与镜头驱动器有线连接;本实施例的控制方法还包括:

步骤S40,在检测到数据信号接口未与镜头驱动器连接时,切换为无线信号传输模式。
[根据细则26改正 10.10.2023]
本实施例中,镜头控制装置兼具有线传输和无线传输两种模式,镜头控制装置在有线信号传输模式时,通过数据信号接口输出调节信号;镜头控制装置在无线信号传输模式时,通过无线发送调节信号。可选的,数据信号接口在与镜头驱动器连接时,向控制器反馈一种信号,在没有与镜头驱动器连接时,向控制器反馈另一种信号,从而控制器根据数据信号接口反馈的信号判断数据信号接口是否与镜头驱动器连接,进而控制切换至相应的信号输出模式;当然,控制器还可以通过其它方式检测判断数据信号接口是否与镜头驱动器连接。本实施例控制方法,根据数据信号接口是否与镜头驱动器连接,自动切换至相应的信号传输模式,使镜头控制装置可在无线传输模式和有线传输模式之间智能切换。
[根据细则26改正 10.10.2023]

步骤S60,根据获取的位置数据和匹配标识生成相应的调节信号进行无线发送。
[根据细则26改正 10.10.2023]
当用户给主体新接入附件时,控制器检测到新的附件接入,则获取该新接入附件的调节件的位置数据和对应的匹配标识。控制器中可存有每个接口对应的匹配标识,新接入的附件的匹配标识可为其连接的那一个接口对应的匹配标识。在获取到新接入的调节件的位置数据和匹配标识后,根据获取的位置数据和匹配标识生成包含该匹配标识的调节信号通过无线发送,以使与该新接入的调节件对应的镜头驱动器调节至与该调节件同步。

步骤S80,在检测有附件断开时,取消用于显示附件的调节件的数据信息的显示区域。
[根据细则26改正 10.10.2023]
镜头控制装置每接入一个附件,控制显示屏上新增一个显示区域,使各个调节件的数据信息分区域显示,每个调节件对应一个显示区域。例如,在镜头控制装置的主体上没有接附件时,显示屏的数据显示区域为单区域,显示主体的调节件的数据信息,在主体上连接一个附件时,显示屏的数据显示区域划分成双区域,在主体上连接两个附件时,显示屏的数据显示区域划分成三区域,每个区域显示对应的调节件的数据信息。
[根据细则26改正 10.10.2023]
