在一种可能的实现方式中,根据所述目标调节策略,对光圈中的第一电极和第二电极进行调节,包括:根据所述目标调节策略,对所述第一电极和所述第二电极的电性状态进行调节,以及,对所述第一电极的各第一子电极和各第二子电极的通断状态进行调节。
基于上述技术内容,通过对第一电极和第二电极的电性状态、通断状态进行调节,使第一控制电路形成多种与目标调节策略对应的电路结构,通过不同的电路结构控制带电粒子的定向移动,进而实现将光圈调节至目标光圈值的目的,由于对第一电极和第二电极的电性状态、通断状态进行调节,形成多种与目标调节策略对应的电路结构,能够使带电粒子稳定的处于与该电路结构对应的位置状态,相对于连续调节带电粒子位置状态的方案,本申请能够实现对带电粒子更加稳定的控制,进而实现光圈更加稳定的光圈值控制。
在一种可能的实现方式中,比较所述目标光圈值与当前光圈值,确定目标调节策略,包括:若目标光圈值大于当前光圈值,将预设的第一调节策略确定为目标调节策略,其中,所述第一调节策略用于表征当目标光圈值大于当前光圈值时,所述第一电极和所述第二电极的电性状态,以及各所述第一子电极和各所述第二子电极的通断状态;若目标光圈值小于当前光圈值,将预设的第二调节策略确定为目标调节策略,其中,所述第二调节策略用于表征当目标光圈值小于当前光圈值时,所述第一电极和所述第二电极的电性状态,以及各所述第一子电极和各所述第二子电极的通断状态。

基于上述技术内容,通过获取用于表征光圈的姿态的姿态参数,确定对应的电压参数,并根据该电压参数对第一电极和第二电极的电压进行调节,由于光圈中的带电粒子,具有一定的质量,对于一些质量较大的带电粒子,会受到重力的影响而产生偏移,通过光圈不同的姿态,对应的调节相应位置的电极的电压值,以克服重力对带电粒子产生的影响,使带电粒子能够准确的定向移动至目标区域,实现准确的遮光,提高光值的控制精度,提高光圈的透光效果。
在一种可能的实现方式中,在所述获取控制信号之前,还包括:获取预设的初始化调节策略;根据所述初始化调节策略,对所述光圈初始化。

基于上述技术内容,通过对光圈进行初始化,使光圈依次处于最大光圈值和最佳光圈值处,由于在电子设备内的光圈在不工作时,出于省电方面的考虑,往往不对其进行通电,因此,光圈内的带电粒子,处于布朗运动状态,若摄像组件开始工作后,光圈直接进行光圈值的调节,会造成部分距离较远的带电粒子无法准确的移动至目标子电极位置,影响光圈的透光效果,而本申请通过对光圈进行初始化,使光圈先处于最大光圈值,再处于最佳光圈值,即使带电粒子先全部定向移动至最大光圈位置进行集中,再使带电粒子移动至最佳的光圈值对应的位置,减少未被电极吸引的游离带电粒子的数量,提高光圈的透光效果和光圈值的控制精度。

本申请的实施方式部分使用的术语仅用于对本申请的具体实施例进行解释,而非旨在限定本申请,下面将结合附图对本申请实施例的实施方式进行详细描述。
本申请实施例提供了一种光圈,应用于摄像组件,摄像组件设置在电子设备内用于实现电子设备的拍摄功能,其中,电子设备可以包括但不限于为手机、平板电脑、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer,UMPC)、手持计算机、对讲机、上网本、POS机、个人数字助理(personal digital assistant,PDA)、行车记录仪、安防设备等设置有摄像组件的移动或固定终端。
图1为本申请实施例提供的光圈的一种应用场景示意图,如图1所示,电子设备为手机,手机内设置有包含了本申请实施例提供的光圈100的摄像组件10,其中,在图1所示应用场景中,包含了本申请实施例提供的光圈的摄像组件10对应设置在手机的前置摄像头1的位置,当然,该摄像组件10也可以设置在后置摄像头或升降摄像头的位置,从而使手机能够通过该摄像组件10,实现拍摄功能。在图1所示的应用场景中,为了满足手机的外观和屏幕设计需求,手机内设置的摄像组件10需要满足必要的尺寸要求,传统的可变光圈摄像组件10,由于采用的是基于机械驱动的光圈结构,需要放置电磁驱动机构、叶片等部件,导致尺寸较大,无法满足在手机内设置的尺寸要求,因此,现有的摄像组件10往往采用的是不可变光圈,以实现摄像组件10的小型化,进而满足手机的设计要求,但也同时导致了手机的拍摄无法实现变光圈功能。同时,由于机械驱动结构在使用时,容易受到潮湿、灰尘等环境因素的影响而导致运行精度下降和使用寿命缩短的问题,降低了摄像组件10的可靠性。
本申请实施例提供的光圈100,采用通过多电极控制用于遮光的带电粒子定向移动的方式对光圈进行调节,能够避免基于机械驱动的光圈尺寸过大、可靠性差的问题。
图2为本申请实施例提供的一种光圈的示意图,如图2所示,该光圈100包括:

其中,第一透光结构110和第二透光结构120可以为高透光性的板状结构,更具体地,例如材质为光学石英玻璃的玻璃基板,厚度为0.3至1毫米。光学石英玻璃具有高度的透明性、化学及物理学上的高度均匀性,具有特定和精确的光学常数,能够提供更好地透光效果。当然,可以理解的是,对于不同的应用场景和应用需求,玻璃基板还可以是其他的透光玻璃,例如有色光学玻璃、蓝宝石玻璃、钢化玻璃等,此处,不对第一透光结构110和第二透光结构120的具体材质进行限定。
示例性地,非导电的透明溶液可以为纯水或甘油,在对光圈的电极通电调节光圈大小的过程中,能够使非导电的透明溶液中的电流小于1mA。在一种可能的实现方式中,为了提高带电粒子140移动的均匀性,第一透光结构110和第二透光结构120之间的容纳空间130内充满非导电的透明溶液。
示例性地,带电粒子140可以带正电,也可以带负电,可以根据带电粒子140的材料确定,带电粒子140可为高分子微粒,例如通过乳化聚合的方法、种子(seed)乳化聚合法、无乳化剂聚合法、分散聚合法、悬浊聚合法等方法制得。更加具体地,高分子微粒的材料为苯乙烯类、苯乙烯-丙烯基类、苯乙烯-异戊二烯类、二乙烯苯类、甲基丙烯酸甲酯类、甲基丙烯酸甲酯类、甲基丙烯酸酯类、甲基丙烯酸乙酯类、丙烯酸乙酯类、丙烯酸正丁酯类、丙烯酸类、丙烯腈类、丙烯酸酯橡胶-甲基丙烯酸类、乙烯类、乙烯-丙烯酸类、尼龙类、聚硅氧烷类、氨基甲酸乙酯类、蜜胺类、苯代三聚氰二胺类、苯酚类、氟(四氯乙烯类)、氯乙烯类、季吡啶鎓盐类、合成橡胶、纤维素、醋酸纤维素、脱乙酰壳多糖、藻酸钙等,此处,不对带电粒子140的类型进行具体限定。
示例性地,为了使带电粒子140能够实现遮光的目的,带电粒子140可以为使用无机颜料或者有机染料进行染色后的高分子微粒,其中,无机颜料例如为:碳黑、铁黑、锰铁氧体黑、钴铁氧体黑、铜铬黑、铜铬锰黑、钛黑、铝粉、铜粉、铅粉、锌粉等。
在一种可能的实现方式中,第一透光结构110和第二透光结构120的外周边缘,设置有环形密封结构115,如图2A所示,环形密封结构115与第一透光结构110和第二透光结构120的外周边缘连接,使第一透光结构110、第二透光结构120、环形密封结构115形成密封的容纳空间130。可以理解的是,环形密封结构115的实现方式有多种,以及对应能够实现不同的功能,此处不对环形密封结构115进行具体限定,只要其能够实现与第一透光结构110、第二透光结构120的外周边缘连接,形成封闭的容纳空间即可。
在另一种可能的实现方式中,第一透光结构110和第二透光结构120为圆形玻璃基板,第一透光结构110和第二透光结构120之间设置有贮存结构170,图3为本申请实施例提供贮存结构170的示意图,如图3所示,贮存结构170具有内腔,用于存储带电粒子140。贮存结构170围设在第一透光结构110和第二透光结构120的外周边缘,且贮存结构170的内腔与容纳空间130相通,第一透光结构110和第二透光结构120的外周边缘分别与贮存结构170的密封连接,贮存结构170可以起到与图2A中环形密封结构115相同的作用,使容纳空间130和贮存结构170的内腔共同组成一个封闭空间,示例性地,贮存结构170的两端分别与第一透光结构110和第二透光结构120的外边缘通过卡合、焊接、胶合或紧固件密封相连。贮存结构170可以为膨胀系数和玻璃基板接近的导电材料,比如镁铝合金,贮存结构170向外一侧预留一个灌装孔,用于向内腔和容纳空间130组成的封闭空间内灌装带电粒子140和非导电的透明溶液。
本申请中,通过设置用于对带电粒子140进行储存的贮存结构170,能够在具体的使用场景下,将容纳空间130内的带电粒子140全部存储至贮存结构170内,使带电粒子140处于更加稳定的状态,减少由于出现游离的带电粒子140而导致影响光圈透光的问题,提高光圈的透光效果和透光稳定性。
光圈还包括第一电极150和第二电极160,示例性的,第一电极150,包括多个透明的第一子电极151以及与第一子电极151相对的多个透明的第二子电极152,示例性地,第一子电极151和第二子电极152为氧化铟锡(Indium Tin Oxides,ITO)电极,多个第一子电极151间隔设置于第一透光结构110朝向第二透光结构120的一面,多个第二子电极152间隔设置于第二透光结构120朝向第一透光结构110的一面,示例性地,多个第一子电极151之间存在间隔带,该间隔带可以为绝缘材质,间隔带随着相邻的两个第一子电极 152的延伸方向延伸设置,以使多个第一子电极151之间产生隔离,防止各第一子电极之间由于导电而相互影响。示例性地,相邻两个第一子电极151之间的间隔和相邻两个第二子电极152之间的间隔均介于1-100微米。
第二电极160,第二电极160围设在第一透光结构110和第二透光结构120的外周边缘处,第一电极150与第二电极160电性相反;带电粒子140在第一电极150和第二电极160的作用下定向移动以对容纳空间130的不同区域进行遮光。其中,定向移动是指带电粒子沿光圈的径向移动。在一种可能的实现方式中,多个第一子电极151和多个第二子电极152均为同心设置的多个环形电极,多个第一子电极151与多个第二子电极152一一对应设置,例如,各第一子电极151与各第二子电极152一一相对设置,各第一子电极151在第二子电极所在平面上的投影重合。各第一子电极151和各第二子电极152分别与第二电极160形成电势差,使带电粒子140能够被驱动,而在容纳空间130内,沿镜头的径向移动,从而实现不同光圈大小所对应的不同区域遮挡覆盖。
示例性地,第一透光结构110和第二透光结构120平行设置,第一透光结构110背离第一子电极151的一面和第二透光结构120背离第二子电极152的一面之间的距离小于2毫米。
示例性地,第一透光结构110设置第一子电极151的一面与第二透光结构120设置第二子电极152的一面之间的距离小于100微米。
具体地,多个第一子电极151和多个第二子电极152均为同心设置的多个环形电极,各第一子电极151和各第二子电极152的半径由小至大逐渐变化,分别对应不同的光圈值。图4为本申请实施例提供的第一子电极151和第二子电极152驱动带电粒子140的示意图,如图4所示,各第一子电极151与各第二子电极152相对设置,当第一子电极151和与其对应的第二子电极152通电后,可以将带电粒子140吸引至该环形第一子电极151和第二子电极152位置处,形成一个环形遮蔽;当多个第一子电极151和与其对应的第二子电通电后,即可实现对特定区域的遮光,形成不同的光圈值大小。
在一种可能的实现方式中,第二电极160设在贮存结构170朝向容纳空间130的一面上,在另一种可能的实现方式中,贮存结构170为导电材料制成的壳体,贮存结构170本身作为第二电极160。当第一电极150和第二电极160通电后,能够对带电粒子140产生吸引,从而使带电粒子140定向移动,并固定在容纳空间130中或贮存结构170的内腔中的某一区域,实现对穿过第一透光结构110和第二透光结构120的光线进行遮挡,从而实现光圈大小的调节。
本申请中,通过在第一透光结构110和第二透光结构120之间的容纳空间130内,设置用于遮光的带电粒子140,并通过设置于第一透光结构110、第二透光结构120上的第一电极150和设置于外围边缘的第二电极160对该带电粒子140进行控制,由于第一电极150和第二电极160各包括多个相对设置的子电极,能够将带电粒子140吸引至不同的位置,使带电粒子140的定向移动实现对不同区域的遮光,进而实现光圈100的调节,结构简单且无需设置额外的机械结构,第一透光结构110、第二透光结构120以及之间的容纳空间130,可以压缩至2毫米以内,有效的压缩了光圈100的结构体积,同时避免了使用机械结构带来的使用寿命较短、可靠性差的问题,提高了光圈100的可靠性。
图5为本申请实施例提供的另一种光圈的结构示意图,如图5所示,本实施例提供的 光圈在图2所示的光圈的基础上,增加用于对第一电极150和第二电极160进行控制的控制电路,在一种可能的实现方式中,光圈还包括:

示例性地,第一控制电路180包括输入端和输出端,其中,输入端与直流电源2的正负极电连接,输出端分别与第一电极150、第二电极160电连接,以使直流电源2分别与第一电极150、第二电极160连通,其中,直流电源2的电压在1.8-12伏之间,能够驱动带电粒子140的定向移动。控制电路内包括多个控制支路,通过调节控制支路的通断状态,改变第一控制电路180的结构,从而实现对第一电极150、第二电极160的电性调节,以及各第一子电极151和各第二子电极152的通断状态调节。下面以一种具体的实现方式进行说明。
图6为本申请实施例提供的第一控制电路180的结构示意图,如图6所示,在一种可能的实现方式中,第一控制电路180包括:第一控制支路181,第一控制支路181的第一端与直流电源2的负极电连接,第二端与第二电极160电连接;第二控制支路182,第二控制支路182的第一端与直流电源2的负极电连接;第三控制支路183,第三控制支路183的第一端与直流电源2的正极电连接,第二端与第二电极160电连接;第四控制支路184,第四控制支路184的第一端与直流电源2的正极电连接;多个并联支路185,各并联支路185的第一端分别与多个第一子电极151,和/或多个第二子电极152电连接,各并联支路185的第二端并联后分别与第二控制支路182的第二端、第四控制支路184的第二端电连接;第一控制支路181、第二控制支路182、第二控制支路182、第二控制支路182以及多个并联支路185上分别设置有控制开关186。在一种可能的实现方式中,控制开关186可以根据具体的指令信息切换、保持为断开或闭合状态,其中,指令信息可以为电子设备中的控制器向调压单元发送的控制指令。示例性地,控制开关186的开闭动作可以通过光耦或者场效应管来实现。
更加具体地,例如,当第一控制支路181、第四控制支路184上的控制开关186闭合,第二控制支路182、第三控制支路183上的控制开关186断开,此时,第一电极150的电性为负电;第二电极160的电性为正电;同时,多个并联支路185上的控制开关186全部闭合,此时,第一子电极151和各第二子电极152全部通电。
再例如,当第一控制支路181、第四控制支路184上的控制开关186断开,第二控制支路182、第三控制支路183上的控制开关186闭合,此时,第一电极150的电性为正电;第二电极160的电性为负电;同时,多个并联支路185中L1、L2、L3支路上的控制开关186闭合,L4支路上的控制开关186断开,则,与L1、L2、L3支路对应的各第一子电极151和各第二子电极152通电,与L4支路对应的第一子电极151和第二子电极152断电。
需要说明的是,图6所示的第一控制电路180的结构,只是实现第一控制电路180的具体方式之一,其他能够实现相同功能的等效电路均可视为第一控制电路180,此处不进行一一例举。
本申请中,通过设置用包括多个控制控制支路和并联支路185的第一控制电路180, 实现对第一电极150和第二电极160的电性的调节,进而实现对带电粒子140的精准控制,使带电粒子140能够准确的移动至特定的区域实现遮光。

示例性地,第二控制电路190获取光圈的姿态参数来确定光圈100的姿态,其中,光圈的姿态是指片状结构的光圈100在空间中与地面的角度关系。获取姿态参数的方式有多种,示例性地,第二控制电路190接受电子设备内的控制器发送的姿态参数,更加具体地,例如控制器通过电子设备内陀螺仪的数据确定姿态参数,或者控制器通过相机采集的图像数据确定姿态参数,第二控制电路190获取控制器发送的姿态参数后,可以相应的确定光圈的姿态。之后,第二控制电路190根据光圈100的姿态,调节直流电源输出至各第一子电极151和各第二子电极152的电压,以使各第一子电极151和各第二子电极152的电压与光圈100的姿态相匹配。示例性地,第二控制电路190可以为设置于第一电极150与直流电源2之间的多输出的调压单元,调压单元的输出端分别与第一电极150的各第一子电极151和各第二子电极152连接,调压单元可以根据具体的指令信息调节并向第一电极150的各第一子电极151和各第二子电极152输出不同的电压,以使第一电极150的各第一子电极151和各第二子电极152具有不同的电压值。其中,指令信息可以为电子设备中的控制器向调压单元发送的控制指令,调压单元的具体实现方式为本领域现有技术,此处不再赘述。
本申请中,通过设置第二控制电路190,实现对第一电极150和第二电极160之间电压的控制,使第一子电极151和第二子电极152具有不同的电压,由于带电粒子140在第一电极150和第二电极160的作用下进行定向移动时,各子电极之间的实际性能往往与理论值存在差异,尤其是随着各子电极使用时间的增加,各子电极的性能也会出现变化,同时,带电粒子140受到外界如重力的影响,也会使其定向移动的精确性受到影响,而通过调节各子电极的电压,能够进一步的提高各子电极对带电粒子140进行控制的精确性,提高光圈的控制精度。
本申请实施例还提供了一种光圈控制方法,用于对如图2-图7所对应的任一实现方式提供的光圈100进行控制,示例性地,该方法的执行主体可以为电子设备的控制器,控制器与光圈100电连接,控制器能够获取光圈100的状态并对光圈进行控制。图8为本申请实施例提供的一种光圈控制方法的流程示意图,如图8所示,该方法包括:
S101、获取控制信号,控制信号中包括目标光圈值。
示例性地,控制信号可以为用于调节光圈值大小的控制信息,例如,相机应用程序发出的光圈调节指令、购物应用程序在扫码时发出的光圈调节指令等。其中,控制信号内包括目标光圈值,即光圈大小调整的目标量。目标光圈值例如为:F1,4、F2.8、F4.0,当然,也可以是与光圈值具有映射关系的标识,此处不对此进行具体限定。
S102、比较目标光圈值与当前光圈值,确定目标调节策略。
获取光圈当前的光圈值并与目标光圈值进行比较,根据当前的光圈值并与目标光圈值的大小关系,确定对应的目标调节策略。由于带电粒子带有特定的电性,因此在对带电粒子进行定向移动控制时,需要根据带电粒子移动的方向,对应的调节第一电极和第二电极 的电性才能实现,即光圈由小变大和由大变小时,其调节策略是不同的,因此,根据目标光圈值与当前光圈值的关系,需要确定具体的目标调节策略,进而根据目标调节策略实现带电粒子在第一电极和第二电极的作用下定向移动。
图9为本申请实施例提供的一种确定目标调节策略的示意图,如图9所示,在一种可能的实现方式中,若目标光圈值大于当前光圈值,将预设的第一调节策略确定为目标调节策略,其中,第一调节策略用于表征当目标光圈值大于当前光圈值时,第一电极和第二电极的电性状态,以及各第一子电极和各第二子电极的通断状态;若目标光圈值小于当前光圈值,将预设的第二调节策略确定为目标调节策略,其中,第二调节策略用于表征当目标光圈值小于当前光圈值时,第一电极和第二电极的电性状态,以及各第一子电极和各第二子电极的通断状态。
当然,可以理解的是,确定对应的目标调节策略还有其他多种实现方式,例如根据目标光圈值与当前光圈值的差值,或者根据目标光圈值与当前光圈值的比值,确定不同的目标调节策略,可以根据具体的需要进行设置,此处不对此进行限定。
S103、根据目标调节策略,对光圈中的第一电极和第二电极进行调节,使带电粒子定向移动以对容纳空间的不同区域进行遮光,形成目标光圈,其中,目标光圈的光圈值为目标光圈值。
图10为本申请实施例提供的一种对第一电极和第二电极进行调节的示意图,如图10所示,目标调节策略可以为使光圈由当前光圈值变为目标光圈值对应的第一电极和第二电极的调节方法,更加具体地,例如为一种映射关系表或逻辑表达式,用于使由当前光圈值变化至目标光圈值与第一电极、第二电极的状态之间产生映射关系。
在一种可能的实现方式中,目标调节策略可以用于对一电极和第二电极的电性状态的调节,以及对一电极中各第一子电极和各第二子电极的通断状态进行调节。通过调节第一电极和第二电极的电性状态,以及第一电极中多个子电极的通断状态,使带电粒子能够被带有与之相反电性的电极或子电极所吸引,定向移动至该电极或子电极的位置,形成对该区域的挡住,进而实现光圈大小的变化控制。其中,对第一电极和第二电极进行调节,以改变第一电极和第二电极的电性,和/或第一电极中多个子电极的通断状态的具体实现方法有多种,将在后面的实施例中进行介绍,此处不再具体展开。
本申请中,通过对第一电极和第二电极的电性状态、通断状态进行调节,使第一控制电路形成多种与目标调节策略对应的电路结构,通过不同的电路结构控制带电粒子的定向移动,进而实现将光圈调节至目标光圈值的目的,由于对第一电极和第二电极的电性状态、通断状态进行调节,形成多种与目标调节策略对应的电路结构,能够使带电粒子稳定的处于与该电路结构对应的位置状态,相对于连续调节带电粒子位置状态的方案,本申请能够实现对带电粒子更加稳定的控制,进而实现光圈更加稳定的光圈值控制。
图11为本申请实施例提供的另一种光圈控制方法的流程示意图,如图11所示,本实施例提供的光圈控制方法在图8所示实施例提供的光圈控制方法的基础上,对步骤S103进一步细化,该方法包括:
S201、获取控制信号,控制信号中包括目标光圈值。
S202、比较目标光圈值与当前光圈值,确定目标调节策略。
S203、根据目标调节策略,确定目标光圈值对应的子电极标识,并将与子电极标识对 应的目标子电极设置为通电状态,目标子电极包括一个或多个第一子电极,和对应的一个或多个第二子电极。
示例性地,为了便于对各第一子电极和第二子电极区分,可以预先为第一子电极和第二子电极中的各子电极设置标识,例如,第一电极中包括A1、A2、A3、A4四个第一子电极。通过子电极标识,可以确定对应的子电极。具体地,光圈中的第一电极包括多个第一子电极和与第一子电极对应的多个第二子电极,其中,保持通电状态的一个或多个第一子电极,以及对应的一个或多个第二子电极,能够与第二电极通过放电形成电场,产生对带电粒子的驱动力,从而实现带电粒子的定向移动以及遮光,因此,在对光圈的大小进行控制时,需要确定目标光圈值对应的子电极标识,进而确定目标子电极,并使该目标子电极保持通电状态,以吸引带电粒子聚集至目标子电极的位置,形成与目标光圈值对应大小的环形遮挡区域。
S204、根据目标调节策略,确定第一电极的第一目标电性和第二电极的第二目标电性,并将第一电极设置为第一目标电性,将第二电极设置为第二目标电性,形成目标光圈值对应的光圈。
示例性地,目标调节策略包括第一调节策略和第二调节策略,其中,第一调节策略用于在目标光圈值大于当前光圈值时对光圈进行调节;第二调节策略用于在目标光圈值小于当前光圈值时对光圈进行调节。第一调节策略和第二调节策略的区别,即在于使用第一调节策略或第二调节策略对光圈进行调节时,第一电极的第一目标电性和第二电极的第二目标电性不同。更加具体地,例如,若第一调节策略为目标调节策略时,适用于目标光圈值大于当前光圈值的情况,即调大光圈的场景,此时,需要驱动带电粒子向光圈容纳空间的边缘移动,因此,第一电极的第一目标电性与带电粒子的电性相同;第二电极的第二目标电性与带电粒子的电性相反。对应的,若第二调节策略为目标调节策略时,适用于目标光圈值小于当前光圈值的情况,即调小光圈的场景,此时,需要驱动带电粒子向光圈容纳空间的中心移动,因此,第一电极的第一目标电性与带电粒子的电性相同;第二电极的第二目标电性与带电粒子的电性相反。
图12为本申请实施例提供的目标调节策略的实现方式的示意图,如图12所示,在一种可能的实现方式中,目标调节策略包括用于表征第一电极中多个子电极的通电状态以及第一电极、第二电极的电性的逻辑表,示例性地,电粒子带负电,第一电极中包括A1、A2、A3、A4四个第一子电极以及对应的四个第二子电极,可以对应形成光圈F1.4、F1.8、F2.2、F2.8。若需要将当前光圈值调大至目标光圈值F2.2,则根据第一调节策略,可以确定目标子电极为A1、A2、A3,使A1、A2、A3保持通电状态,同时,使第一电极的第一目标电性为负电,使第二电极的第二目标电性为正电,此时,带电粒子会聚集在A1、A2、A3所在位置处,实现对应区域的遮光,进而使光圈的调大至目标光圈值F2.2。类似的,若需要将当前光圈值调小至目标光圈值F2.8,则根据第二调节策略,可以确定目标子电极为A1、A2、A3、A4,使A1、A2、A3、A4保持通电状态,同时,使第一电极的第一目标电性为正电,使第二电极的第二目标电性为负电,此时,带电粒子会聚集在A1、A2、A3、A4所在位置处,实现对应区域的遮光,进而使光圈的调小至目标光圈值F2.8。
在一种可能的实现方式中,光圈为上述如图6所对应的实施例提供的光圈,光圈中包括第一控制电路,第一控制电路的多个控制支路以及多个并联支路上分别设置有控制开关, 控制器与控制开关电连接,并能够控制该控制开关的开闭。步骤S203中将目标子电极设置为通电状态,以及步骤S204中将第一电极设置为第一目标电性,将第二电极设置为第二目标电性可以为:根据目标调节策略,向第一控制电路的多个控制支路以及多个并联支路上设置的控制开关发送控制指令,使控制开关处于与目标光圈值对应的开闭状态。
图13为本申请实施例提供的另一种目标调节策略的实现方式的示意图,如图13所示,在一种可能的实现方式中,目标调节策略包括用于表征控制开关的开闭状态的逻辑表。其中,1表示控制开关闭合,0表示控制开关断开。示例性地,电粒子带负电,第一电极中包括A1、A2、A3、A4四个第一子电极以及对应的四个第二子电极,可以对应调节光圈为F1.4、F1.8、F2.2、F2.8。多个控制支路上设置有控制开关Ka、Kb、Kc、Kd;多个并联支路上分别设置有控制开关K1、K2、K3、K4。
示例性地,若需要将当前光圈值调大至目标光圈值F2.2,则根据第一调节策略,可以确定目标子电极为A1、A2、A3,需要使A1、A2、A3保持通电状态,即,控制开关K1、K2、K3闭合,K4断开;同时,使第一电极的第一目标电性为负电,使第二电极的第二目标电性为正电,即,控制Kc、Kd闭合,Ka、Kb断开,此时,由于带电粒子带负电,而第二电极与电源的正极连通而带有正电,因此,带电粒子在第二电极的吸引下,会向第二电极移动聚集,从而使光圈调大,在带电粒子移动至A1、A2、A3所在位置处时,对应的目标光圈值为F2.2。而后,在下一时间单位,由于带电粒子被第二电极吸引而继续向第二电极方向移动,使当前光圈值继续变大,此时,需要切换第一电极和第二电极的电性,即控制Kc、Kd断开合,Ka、Kb闭合,使第一电极的第一目标电性为正电,使第二电极的第二目标电性为负电,吸引带电粒子会聚集在A1、A2、A3所在位置处,实现对应区域的遮光,进而使光圈的相对当前光圈值缩小至目标光圈值F2.2,重复上述动作,使带电粒子动态的保持在目标光圈值F2.2位置,从而实现将当前光圈值调大至目标光圈值F2.2的目的。
类似的,若需要将当前光圈值调小至目标光圈值F2.8,则根据第二调节策略,可以确定目标子电极为A1、A2、A3、A4,需要使A1、A2、A3、A4保持通电状态,即,控制开关K1、K2、K3、K4闭合;同时,使第一电极的第一目标电性为正电,使第二电极的第二目标电性为负电,即,控制Ka、Kb闭合,Kc、Kd断开,此时,带电粒子会聚集在A1、A2、A3、A4所在位置处,在下一时间单位,切换第一电极和第二电极的电性,即控制Ka、Kb断开,Kc、Kd闭合,使第一电极的第一目标电性为负电,使第二电极的第二目标电性为正电,吸引带电粒子向第二电极方向移动,重复上述动作,使带电粒子动态的保持在目标光圈值F2.8位置,从而实现将将当前光圈值调小至目标光圈值F2.8的目的。
在一种可能的实现方式中,在步骤S204之后,还包括:
S205、根据配置信息,对光圈中的第一电极和第二电极的电压进行调节。
示例性地,第一电极包括多个第一子电极和多个第二子电极,对光圈中的第一电极和第二电极的电压进行调节包括对多个第一子电极、多个第二子电极、第二电极中的任意电极的电压进行使第一子电极和第二子电极具有不同的电压,由于带电粒子在第一电极和第二电极的作用下进行定向移动时,各子电极之间的实际性能往往与理论值存在差异,尤其是随着各第一子电极、第二子电极使用时间的增加,电极的性能也会出现变化,同时,带电粒子受到外界如重力的影响,也会使其定向移动的精确性受到影响,而通过调节各子电 极的电压,能够进一步的提高各子电极对带电粒子进行控制的精确性,提高光圈的控制精度。
在一种可能的实现方式中,如图14所示,S205包括S2051、S2052、S2053三个具体的实现步骤:
S2051、获取姿态参数,姿态参数用于表征光圈的姿态。
示例性地,光圈为片状结构,光圈的姿态是指片状结构的光圈在空间中与地面的角度关系。获取姿态参数的方式有多种,由于光圈是固定设置在电子设备内的,因此,可以根据表征电子设备的姿态的参数确定姿态参数,例如,通过获取电子设备内陀螺仪的数据作为姿态参数,获取通过相机采集的图像数据确定姿态参数,姿态参数的实现形式也有多种,例如可以为水平倾斜度,或者不同倾斜度对应的标识信息,此处不对获取姿态参数的方式和姿态参数的实现方式进行具体限定。
S2052、根据目标调节策略,确定姿态参数对应的电压参数。
S2053、根据电压参数,对第一电极和第二电极的电压进行调节。示例性地,目标调节策略中还包括有姿态参数与对应电压参数的映射关系,例如,当姿态参数为90o时,根据目标调节策略,可以确定对应的电压参数,更具体地,电压参数可以为一个数组,数组中包括分别与各电极对应的多个电压值。根据该多个电压值,对第一电极中的多个第一子电极和第二电极的电压分别进行调节,使其具有不同的电压值,进而改变各电极对带电粒子的驱动能力,由于光圈中的带电粒子,具有一定的质量,对于一些质量较大的带电粒子,会受到重力的影响而产生偏移,通过光圈不同的姿态,对应的调节相应位置的电极的电压值,以克服重力对带电粒子产生的影响,使带电粒子能够准确的定向移动至目标区域,实现准确的遮光,提高光值的控制精度,提高光圈的透光效果。
在一种可能的实现方式中,在步骤S201之前,还包括:
S200、根据预设的初始化调节策略,对光圈初始化。
示例性地,对光圈初始化,包括控制光圈中第一电极和第二电极的状态,驱动带电粒子定向移动,以使光圈具有一个特定的光圈值,在需要使用该光圈进行透光成像时,可以直接使用该最佳光圈值进行成像,无需进行额外调节,提高利用该光圈进行摄像的效率,其中,最佳光圈值可以根据需要进行预设,此处不对其进行具体限定。
由于在电子设备内的光圈在不工作时,出于省电方面的考虑,往往不对其进行通电,因此,光圈内的带电粒子,处于布朗运动状态,若摄像组件开始工作后,光圈直接进行光圈值的调节,会造成部分距离较远的带电粒子无法准确的移动至目标子电极位置,影响光圈的透光效果,而本申请通过对光圈进行初始化,使光圈先处于最大光圈值,再处于最佳光圈值,即使带电粒子先全部定向移动至最大光圈位置进行集中,再使带电粒子移动至最佳的光圈值对应的位置,减少未被电极吸引的游离带电粒子的数量,提高光圈的透光效果和光圈值的控制精度。
在一种可能的实现方式中,如图15所示,S200包括S2001、S2002、S2003三个具体的实现步骤:
S2001、根据预设的第二调节策略和预设的最大光圈值,对光圈中的第一电极和第二电极进行调节,使带电粒子聚集于容纳空间中最大光圈值对应的区域。
S2002、根据预设的第一调节策略和预设的最佳光圈值,对光圈中的第一电极和第二 电极进行调节,使带电粒子聚集于容纳空间中最佳光圈值对应的区域。
第二调节策略为调大光圈时的目标调节策略,根据第二调节策略,对光圈中第一电极和第二电极的状态进行控制,使带电粒子向光圈的容纳空间的边缘位置聚集,之后再通过第一调节策略,即缩小光圈时的调节策略,对对光圈中第一电极和第二电极的状态进行控制,使带电粒子向光圈的中心位置聚集,并停留至最佳光圈值对应的第一子电极和第二子电极位置,使光圈具有最佳光圈值。其中,通过对第一电极和第二电极进行控制的具体实现方式,在图11所示的实施例步骤S203-S204中已进行详细,此处不再赘述。
本申请中,通过对光圈进行初始化,使光圈依次处于最大光圈值和最佳光圈值处,由于在电子设备内的光圈在不工作时,出于省电方面的考虑,往往不对其进行通电,因此,光圈内的带电粒子,处于布朗运动状态,若摄像组件开始工作后,光圈直接进行光圈值的调节,会造成部分距离较远的带电粒子无法准确的移动至目标子电极位置,影响光圈的透光效果,而本申请通过对光圈进行初始化,使光圈先处于最大光圈值,再处于最佳光圈值,即使带电粒子先全部定向移动至最大光圈位置进行集中,再使带电粒子移动至最佳的光圈值对应的位置,减少未被电极吸引的游离带电粒子的数量,提高光圈的透光效果和光圈值的控制精度。
在一种可能的实现方式中,在步骤S2002之后,还包括:
S2003、获取初始化电压参数;根据初始化电压参数,对第一电极和第二电极的电压进行调节,使带电粒子聚集于容纳空间中最佳光圈值对应的区域。
示例性地,初始化电压参数可以为一个数组,数组中包括分别与各电极对应的多个电压值。根据该多个电压值,对第一电极中的多个第一子电极和第二电极的电压分别进行调节,使其具有不同的电压值,进而改变各电极对带电粒子的驱动能力。其中,初始化电压参数可以为用户根据具体的需要输入控制器的电压参数,也可以是控制器根据其他参数计算而获得的电压参数,此处不对确定初始化电压参数的方法进行具体限定。
其中,对第一电极和第二电极的电压进行调节的实现方式,在图11所示的实施例步骤S205中已进行详细,此处不再赘述。
本申请中,通过在初始化过程中,根据预设的初始化电压参数,对光圈初始化,使初始化后的第一电极和第二电极,具有不同的电压值,达到对电极的电压值进行修正的效果,提高光圈值的控制精度。
其中,需要说明的是,步骤S2003可以在步骤S2001、S2002之后执行,也可以单独执行;步骤S2001、S2002也可以脱离步骤S2003而单独执行,此处不对其进行限定。
