请参考图1，其示出了根据本公开的灯光亮度调节方法的一个实施例的流程。该灯光亮度调节方法可以应用于包括摄像头的终端设备，例如，台灯。如图1所示该灯光亮度调节方法，包括以下步骤：
步骤101，响应于检测到图像采集设备处于预定义状态，根据图像采集设备确定的环境亮度值，确定图像采集设备的采集区域的第一照度值。
在这里，图像采集设备可以理解为带有摄像功能的设备，例如，摄像头。
在这里，预定义状态可以理解为图像采集设备处于图像采集状态，例如，当图像采集设备为摄像头时，则可以理解为，摄像头处于可以采集图像的状态，也即，此时摄像头已经完成对焦，并可以直接进行图像采集。
在这里，环境亮度值与照度值之间可以存在映射关系，环境亮度值与照度值之间通常是二次函数关系。例如，y＝a-bx+cx 2；其中，y可以表征照度值，x可以表征环境亮度值，而a、b、c可以是根据实际情况而设置的固定参数。而通过这种映射关系，则可以利用环境亮度值确定照度值。
作为示例，由于环境亮度值与照度值之间存在映射关系，因此，当环境亮度改变之后，采集区域的物体照度也可能会发生改变。例如，当用户开启卧室灯光时(也即，环境亮度值可能变高了)，则采集区域的照度值可能会变高，用户关闭卧室灯光时，采集区域的照度值又可能会变低。又如，当用户拉开窗帘时，采集区域的照度值可能会变高，当用户关闭窗帘时，采集区域的照度值可能会变低。也即，当环境亮度值改变之后，采集区域的照度值也在发生变化。
在这里，图像采集设备的采集区域可以理解为灯具照射区域中的部 分区域，而这部分区域可以理解为用户的阅读区域，或者理解为用户会经常观察的区域。也即，用户可能会在这部分区域放置需要阅读的书籍、浏览电子设备等。为了便于理解，可以如图2A-图2B所示，图2A灯具的照射区域与采集区域的对比示意图，从图2A可以看出，采集区域201为照射区域202的部分区域。进一步结合图2B进行说明，图2B为灯具为台灯时的示意图，图像采集设备204安装在台灯203的顶部区域，而图像采集设备204的采集区域205则可以放置书籍、电子设备等。
作为示例，用户在采集区域放置书籍时，则第一照度值可以理解为放置的书籍的照度值，而当在采集区域放置电子设备时，第一照度可以理解为放置的电子设备的照度值。
作为示例，当图像采集设备处于预定义状态(例如，图像采集设备为摄像头)，当环境亮度不同时，摄像头的镜头焦距、镜头光圈等参数不同，因此，可以根据摄像头的参数，确定环境亮度值。而环境亮度值与照度值之间存在映射关系，因此，可以根据环境亮度值，确定采集区域的第一照度值。
步骤102，基于预设照度值与第一照度值，确定是否调节灯具的输出功率。
在这里，输出功率越高，则灯具所发出的灯光强度就越高，相应的，当输出功率越低时，灯具发出的灯光强度就越低。而灯具的输出功率发生变化时，环境亮度值也就会发生变化，相应的，采集区域的照度值也就可以发生变更。因此，可以通过更改输出功率，变更采集区域的照度值。
在这里，当采集区域的照度值为预设照度值时，可以让用户拥有较好的视角感官体验；也可以理解为，用户在预设照度值下进行浏览，可以使得用户的眼部不易产生疲惫感。
作为示例，当第一照度值与预设照度值之间的差值较大时，则可以表 征此时采集区域的照度值可能会使用户视觉感官体验较差，进而，可以将采集区域的照度值进行调节；以使用户可以拥有较好的视觉感官体验。
可以看出，在本申请中，当图像采集设备处于预定义状态时，可以根据图像采集设备确定的环境亮度值，确定图像采集设备的采集区域的第一照度值，并可以根据第一照度值和预设照度值，确定是否调节灯具的输出功率，也即，通过这种方式，可以使得当灯具开启之后，采集区域的照度值不会随着环境亮度值的变更而发生较大变更，从而也就可以保证用户在阅读过程中的视觉感官体验。
在一些实施例中，图像采集设备可以通过如下方式确定环境亮度值：
可以根据光圈大小、曝光时长和镜头感光度这三者，确定环境亮度值。
在一些实施例中，可以根据光圈参数的数值与曝光时间的时长数值，确定第一总和；并可以根据镜头感光度的感光值和第一总和，确定环境亮度值。
作为示例，AV+TV＝BV+SV，其中，AV可以理解为光圈参数、TV可以理解为曝光时间、BV可以理解为环境亮度值、SV可以理解为镜头感光度。从而，即可根据光圈大小、曝光时长和镜头感光度这三者，确定环境亮度值。也即，AV+TV可以看作第一总和，而第一总和减去SV，则可以得到环境亮度值。
作为示例，AV＝2log 2 A，其中，而A可以理解为光圈系数的F值。
Figure PCTCN2022104817-appb-000001
其中，T可以理解为均可以理解为曝光时间。
Figure PCTCN2022104817-appb-000002
B可以理解为环境亮度值，K可以理解为根据实际情况而设定的固定参数；SV可以理解为镜头感光度和S可以理解为标准感光度。
可以看出，通过根据光圈大小、曝光时长和镜头感光度这三者，确定环境亮度值，可以避免桌面颜色及材质的影响，从而可以使得确定出的环境亮度值更加准确。
在一些实施例中，可以根据灯具的照射方向，确定图像采集设备的安装方向。
作为示例，当根据采集设备的照射方向，确定图像采集设备的安装方向时，使得采集区域可能为用户放置需要阅读的数据或者电子设备的区域，也即，用户的浏览区域较为可能为采集区域。也即，通过这种方式，可以使得第一照度值，可以较为准确的反映用户的浏览区域的照度值，从而也就可以更加准确的判断是否需要对灯具的输出功率进行调节
在一些实施例中，步骤102(基于预设照度值与第一照度值，确定是否调节灯具的输出功率)具体可以包括：响应于确定预设照度值与第一照度值的照度差值大于预设阈值，确定调节所述灯具的输出功率；以及，可以响应于确定预设照度值与第一照度值的照度差值不大于预设阈值，确定不调节所述灯具的输出功率。
作为示例，当预设照度值与第一照度值之间的照度差值大于预设阈值时，则可以确定调节灯具的输出功率。而预设阈值可以根据实际情况进行设定，在此并不对预设阈值的具体数值进行限定。
作为示例，采集区域的照度值与环境亮度值相关，因此，当灯具输出相同的输出功率，由于外界环境的其它光线造成的干扰，也可能使得采集区域的照度值不同。进而，可以基于照度差值，确定目标输出功率，而通过这种方式，可以使获得的目标输出功率更为准确，从而，也就可以使得将灯具的当前输出功率调节至目标输出功率时，采集区域的照度值等于或者接近预设照度值。
在一些实施例中，可以根据照度差值，确定与照度差值对应的功率变更量；并可以根据功率变更量和当前输出功率，确定目标输出功率。
在这里，功率变更量可以理解为当前输出功率需要更改的量。
作为示例，可以预先设定照度差值与功率变更量之间的对应关系。从 而，当确定出照度差值之后，则可以确定功率变更量。
在一些实施例中，也可以根据当前输出功率对应的第一档位、照度差值对应的待变更档位数，确定目标档位；并可以根据目标档位，确定目标输出功率。
在这里，档位与输出功率对应。
作为示例，可以预先设定一些档位数，而每个档位可以对应一个输出功率，而通过这种方式，可以预先设定一些固定的输出功率，从而仅需将灯具的输出功率，在固定的输出功率之间进行切换即可。这样，可以简化调节输出功率的电路结构。
作为示例，可以预先设置101个档位数，也即，灯具可以具有101个不同的输出功率。当然，具体需要设置多少个档位数，在此并不进行限定，仅需根据实际情况进行合理设定即可。
在一些实施例中，响应于确定预设照度值与第一照度值之间的照度差大于预设阈值，确定调节上述灯具的输出功率。
在这里，当照度差值大于预设阈值之后，才调节灯具的输出功率，可以避免频繁调节输出功率而引发的频闪现象，从而影响用户的视觉体验。
作为示例，照度值与采集区域的物体类型有关，例如，用户在阅读书籍的过程中；翻页、喝水等操作，均可能会造成照度值的变化。若照度值发生变化之后，立即对灯具的输出功率进行调节，可能使得灯具的输出功率可能一直在变化，从而可能造成频闪现象。
在一些实施例中，响应于接收到输出功率调节指令，根据输出功率调节指令所指示的第二输出功率，将灯具的当前输出功率调节至第二输出功率；根据采集区域的第二照度值，确定预设照度值。
在这里，灯具输出功率为第二输出功率时，采集区域的照度值为第二照度值。
作为示例，用户在浏览过程中，某些用户喜好在冷光环境下阅读，某些用户可能喜欢在暖光环境下阅读，而用户在阅读一些字体较小的书籍和阅读字体较大的书籍，所使用的灯光亮度也可能不同。也即，用户也可以自行输入输出功率调节指令。
作为示例，灯具上可以设置灯具亮度调节控件或者灯具亮度调节按键。当对灯具亮度调节控件或者灯具亮度调节按键执行相应预定义的操作时，则可以表征用户输入了输出功率调节指令，此时，则可以将灯具的当前输出功率调节至第二输出功率。
作为示例，当用户输入输出功率调节指令之后，则可以表征当前照度值并不适合用户阅读，而第二照度值比较适合用户阅读。也可以理解为第二照度值可以让用户拥有较好的视觉体验。此时，也就可以将第二照度值确定为预设照度值，可以使得外界环境亮度变化之后，拍摄区域的照度值还可以一直保持在第二照度值，这样也就可以使用户拥有较好地视觉体验。
在一些实施例中，响应于确定调节灯具的输出功率，根据目标输出功率和当前输出功率之间的差值，确定调节时长。
在这里，目标输出功率与预设照度值对应。
作为示例，目标输出功率与当前输出功率之间的差值可能较大，因此，可以适当延长调节时长，从而避免照度值大幅度变化给用户眼部带来的不适感。因此，可以根据目标输出功率和当前输出功率之间的差值，确定调节时长。
作为示例，可以建立一个差值时长对应表，在差值时长对应表包括目标输出功率和当前输出功率的差值与调节时长的对应关系，也即，可以根据差值时长对应表，获知每次调节输出功率所花费的时长。
在一些实施例中，当灯具的输出功率大于预设功率阈值时，确定图像 采集设备处于预定义状态。
作为示例，在某些情况下(例如，用户需要睡觉时)，可能会将灯具亮度调至较低，此时，灯具可以担任类似指示灯的作用。因此，为了节约能耗，图像采集设备可以不处于预定义状态。也即，仅有当灯具的输出功率大于预设功率阈值时，图像采集设备才处于预定义状态，这样，可以减少灯具的能耗，并可以使灯具更加节能。
进一步参考图3，作为对上述各图所示方法的实现，本公开提供了一种灯光亮度调节装置的一个实施例，该装置实施例与图1所示的灯光亮度调节方法实施例相对应，该装置具体可以应用于包括图像采集设备的各种电子设备中。

附图中的流程图和框图，图示了按照本公开各种实施例的系统、方法和计算机程序产品的可能实现的体系架构、功能和操作。在这点上，流程图或框图中的每个方框可以代表一个模块、程序段、或代码的一部分，该模块、程序段、或代码的一部分包含一个或多个用于实现规定的逻辑功能的可执行指令。也应当注意，在有些作为替换的实现中，方框中所标注的功能也可以以不同于附图中所标注的顺序发生。例如，两个接连地表示的方框实际上可以基本并行地执行，它们有时也可以按相反的顺序执行，这依所涉及的功能而定。也要注意的是，框图和/或流程图中的每个方框、以及框图和/或流程图中的方框的组合，可以用执行规定的功能或操作的专用的基于硬件的系统来实现，或者可以用专用硬件与计算机指令的组合来实现。
描述于本公开实施例中所涉及到的单元可以通过软件的方式实现，也可以通过硬件的方式来实现。其中，单元的名称在某种情况下并不构成对该单元本身的限定，例如，第一确定单元301还可以被描述为“确定图像采集设备的采集区域的第一照度值的单元”。
本文中以上描述的功能可以至少部分地由一个或多个硬件逻辑部件来执行。例如，非限制性地，可以使用的示范类型的硬件逻辑部件包括：现场可编程门阵列(FPGA)、专用集成电路(ASIC)、专用标准产品(ASSP)、片上系统(SOC)、复杂可编程逻辑设备(CPLD)等等。
在本公开的上下文中，机器可读介质可以是有形的介质，其可以包含或存储以供指令执行系统、装置或设备使用或与指令执行系统、装置或设备结合地使用的程序。机器可读介质可以是机器可读信号介质或机器可读储存介质。机器可读介质可以包括但不限于电子的、磁性的、光学的、电磁的、红外的、或半导体系统、装置或设备，或者 上述内容的任何合适组合。机器可读存储介质的更具体示例会包括基于一个或多个线的电气连接、便携式计算机盘、硬盘、随机存取存储器(RAM)、只读存储器(ROM)、可擦除可编程只读存储器(EPROM或快闪存储器)、光纤、便捷式紧凑盘只读存储器(CD-ROM)、光学储存设备、磁储存设备、或上述内容的任何合适组合。
以上描述仅为本公开的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解，本公开中所涉及的公开范围，并不限于上述技术特征的特定组合而成的技术方案，同时也应涵盖在不脱离上述公开构思的情况下，由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本公开中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
此外，虽然采用特定次序描绘了各操作，但是这不应当理解为要求这些操作以所示出的特定次序或以顺序次序执行来执行。在一定环境下，多任务和并行处理可能是有利的。同样地，虽然在上面论述中包含了若干具体实现细节，但是这些不应当被解释为对本公开的范围的限制。在单独的实施例的上下文中描述的某些特征还可以组合地实现在单个实施例中。相反地，在单个实施例的上下文中描述的各种特征也可以单独地或以任何合适的子组合的方式实现在多个实施例中。
尽管已经采用特定于结构特征和/或方法逻辑动作的语言描述了本主题，但是应当理解所附权利要求书中所限定的主题未必局限于上面描述的特定特征或动作。相反，上面所描述的特定特征和动作仅仅是实现权利要求书的示例形式。
