Description
技术领域technical field
本发明涉及电子技术，尤其涉及一种白平衡调整方法和拍摄终端。The invention relates to electronic technology, in particular to a white balance adjustment method and a shooting terminal.
背景技术Background technique
一般而言，物体反射出的光颜色视光源的色彩而定。人的大脑可以检测并更正类似这样的色彩改变，因此不论是阳光、晴天、阴天、日光灯、荧光灯或钨丝灯下，人的眼睛均可以适应这样的色彩改变，而不会影响人们所看到的白色物体。然而，对拍摄终端而言，这些由不同光源产生的白色在颜色上来说还是不尽相同。例如:钨丝灯照明的环境下拍出的照片可能偏黄，其他环境拍出的照片可能偏蓝。故拍摄终端在拍摄照片时，为提高拍摄效果，往往需进行白平衡调整。Generally speaking, the color of light reflected by an object depends on the color of the light source. The human brain can detect and correct color changes like this, so the human eye can adapt to such color changes whether it's sunlight, sunny, cloudy, fluorescent, fluorescent or tungsten lighting, without affecting what people see. to the white object. However, for the shooting terminal, these whites produced by different light sources are still not the same in color. For example: photos taken under tungsten lighting may be yellowish, and photos taken under other environments may be bluish. Therefore, when the photographing terminal takes pictures, in order to improve the photographing effect, it often needs to adjust the white balance.
但在目前的白平衡调整方法中，通常是通过预设环境调整模式进行调整白平衡，如在日光灯模式、荧光模式和钨丝模式等有限的预设环境调整模式，但是，在现有的情况下，往往外界光源复杂，如同时存在钨丝光源和荧光灯光源的混合光源，而现有提供的预设环境调整模式无法进行正确的白平衡调整，从而使得用户无法获得满意理想的照片，给用户带来不便。However, in the current white balance adjustment method, the white balance is usually adjusted through preset environmental adjustment modes, such as limited preset environmental adjustment modes such as fluorescent lamp mode, fluorescent mode and tungsten mode. However, in the existing situation Under such circumstances, the external light source is often complicated, such as the mixed light source of tungsten light source and fluorescent light source, and the existing preset environment adjustment mode cannot perform correct white balance adjustment, so that users cannot obtain satisfactory and ideal photos. bring inconvenience.

Wherein, the above-mentioned shooting terminal is only an example, not exhaustive, including but not limited to the above-mentioned shooting terminal.
参见图1，是本发明实施例提供的一种白平衡调整方法的第一实施例流程示意图。本发明实施例中所描述的一种白平衡调整方法包括步骤：Referring to FIG. 1 , it is a schematic flowchart of a first embodiment of a white balance adjustment method provided by an embodiment of the present invention. A white balance adjustment method described in an embodiment of the present invention includes steps:
S100，获取滚动点在预置的色温刻度进度条上的目标位置。S100. Obtain the target position of the scroll point on the progress bar of the preset color temperature scale.
在本发明实施例中，当拍摄终端需进行拍摄照片，拍摄终端可以自动显示色温刻度进度条，或者，终端用户可操作拍摄设备，拍摄设备进入白平衡调整界面。当拍摄设备进入白平衡调整界面时，拍摄设备可显示多种白平衡调整模式供用户选择，包括自动调整模式、预设环境模式和手动调整模式等。当用户选择手动调整模式时，拍摄设备可显示色温刻度进度条，以使终端用户可通过操作色温刻度进度条选择所需的色温值，从而进行调整拍摄终端的白平衡。In the embodiment of the present invention, when the shooting terminal needs to take photos, the shooting terminal can automatically display the color temperature scale progress bar, or the terminal user can operate the shooting device, and the shooting device enters the white balance adjustment interface. When the shooting device enters the white balance adjustment interface, the shooting device may display multiple white balance adjustment modes for the user to choose from, including an automatic adjustment mode, a preset environment mode, and a manual adjustment mode. When the user selects the manual adjustment mode, the photographing device can display a progress bar of the color temperature scale, so that the end user can select a desired color temperature value by operating the progress bar of the color temperature scale, so as to adjust the white balance of the photographing terminal.
在本发明实施例中，色温刻度进度条的范围可以进行预置，例如，色温刻度进度条的范围可以预置为0～7000K，或者色温刻度进度条的范围还可以预置为2500K～8000K等。可选的，色温刻度进度条的范围还可以由用户根据需要进行预置，在此不进行限制。进一步的，在本发明实施例中，色温刻度进度条还可包括预置间距的色温刻度以及滚动点。其中，色温刻度可如图2，色温刻度可设定为以预置间距100K为单位的小刻度，以预置间距1000K为单位的大刻度，小刻度和大刻度分别用不同的标记显示，其中大刻度的标记可更加醒目，如图2中在大刻度上标上色温值。滚动点在色温刻度进度条上的位置对应于色温值，终端用户可根据色温刻度进度条上显示的色温刻度，在色温刻度进度条上操作滚动点移动到所需的色温值相应的目标位置上，其中，操作滚动点动作还可以包括直接点击色温刻度进度条上的某一位置，例如当终端用户点击色温刻度进度条上的某一位置时，则表示终端用户将滚动点拖动至色温刻度进度条上的该位置上。其中，当滚动点被移动后，拍摄终端可获取滚动点移动后的目标位置，例如：当终端用户拖动滚动点后并停止拖动时，拍摄终端获取滚动点被拖动后直至停止时的目标位置。In the embodiment of the present invention, the range of the progress bar of the color temperature scale can be preset, for example, the range of the progress bar of the color temperature scale can be preset as 0-7000K, or the range of the progress bar of the color temperature scale can also be preset as 2500K-8000K, etc. . Optionally, the range of the progress bar of the color temperature scale can also be preset by the user according to needs, which is not limited here. Further, in the embodiment of the present invention, the progress bar of the color temperature scale may also include color temperature scales with preset intervals and scroll points. Among them, the color temperature scale can be shown in Figure 2. The color temperature scale can be set as a small scale with a preset interval of 100K as a unit, and a large scale with a preset interval of 1000K as a unit. The small scale and the large scale are displayed with different marks. The mark on the large scale can be more eye-catching, as shown in Figure 2, the color temperature value is marked on the large scale. The position of the scroll point on the progress bar of the color temperature scale corresponds to the color temperature value. The end user can operate the scroll point on the progress bar of the color temperature scale to move to the target position corresponding to the required color temperature value according to the color temperature scale displayed on the progress bar of the color temperature scale. , where the action of operating the scroll point may also include directly clicking a certain position on the progress bar of the color temperature scale, for example, when the end user clicks a certain position on the progress bar of the color temperature scale, it means that the end user drags the scroll point to the color temperature scale at that position on the progress bar. Wherein, when the scroll point is moved, the shooting terminal can acquire the target position after the scroll point is moved, for example: when the terminal user drags the scroll point and stops dragging, the shooting terminal obtains the position of the scroll point after it is dragged until it stops target location.
进一步的，拍摄终端还可通过摄像头获取当前外界光线的色温值，并根据外界光线的色温值控制色温刻度进度条上的滚动点移至外界光线的色温值对应的目标位置上，以方便终端用户从色温刻度进度条上读取当前外界光线的色温值。Further, the shooting terminal can also obtain the current color temperature value of the external light through the camera, and control the scroll point on the progress bar of the color temperature scale to move to the target position corresponding to the color temperature value of the external light according to the color temperature value of the external light, so as to facilitate the terminal user Read the current color temperature value of the external light from the progress bar of the color temperature scale.
进一步的，当拍摄终端通过摄像头获取当前外界光线的色温值时，拍摄终端可根据当前外界光线的色温值生成色温刻度进度条并显示色温刻度进度条，其中，该色温刻度进度条的色温刻度范围可以是以当前外界光线的色温值为中心，以间隔为预置间隔的数值为上下限值，如当当前外界光线的色温值为Ct时，预置间隔为1000K时，则色温刻度范围可为(Ct-1000K，Ct+1000K)，如图3所示。从而使得终端用户可更精准地进行手动白平衡调整，获得终端用户所需的摄影作品。其中，终端用户可通过按键或屏幕操作选择终端是获取当前外界光线的色温值进行白平衡调整还是由用户进行手动输入色温值进行白平衡调整。Further, when the shooting terminal obtains the color temperature value of the current external light through the camera, the shooting terminal can generate a color temperature scale progress bar according to the current color temperature value of the external light and display the color temperature scale progress bar, wherein the color temperature scale range of the color temperature scale progress bar It can be centered on the color temperature value of the current external light, and the value of the preset interval is the upper and lower limit values. For example, when the color temperature value of the current external light is Ct and the preset interval is 1000K, the range of the color temperature scale can be (Ct-1000K, Ct+1000K), as shown in Figure 3. Thus, end users can perform manual white balance adjustment more accurately, and obtain photographic works required by end users. Wherein, the terminal user can select whether the terminal obtains the color temperature value of the current external light to adjust the white balance or the user manually inputs the color temperature value to adjust the white balance through buttons or screen operations.
S101，根据预置的位置与色温值的对应关系，获取所述目标位置所对应的目标色温值。S101. Acquire a target color temperature value corresponding to the target position according to a preset correspondence relationship between a position and a color temperature value.
在本发明实施例中，拍摄终端可将色温刻度进度条上的每个色温值对应的每个滚动点的位置的对应关系存储在拍摄终端中。拍摄终端获取到目标位置时，可根据存储的滚动点的位置与色温值的对应关系，获取目标位置对应的目标色温值。In the embodiment of the present invention, the photographing terminal may store in the photographing terminal the correspondence between the positions of each scroll point corresponding to each color temperature value on the progress bar of the color temperature scale. When the shooting terminal acquires the target position, it can acquire the target color temperature value corresponding to the target position according to the stored correspondence between the position of the scroll point and the color temperature value.
S102，根据预置的色温值与颜色增益值的对应关系，获取所述目标色温值所对应的目标颜色增益值。S102. Acquire a target color gain value corresponding to the target color temperature value according to a preset correspondence relationship between a color temperature value and a color gain value.
在本发明实施例中，颜色增益值可包括红色增益值R_gain和蓝色增益值B_gain，该颜色增益值可用于调整图片的蓝色分量或红色分量的输出。其中，拍摄终端可建立色温值与颜色增益值的对应关系。具体的，拍摄终端可建立零散无规律的色温值与颜色增益值的对应关系，如，建立色温值为2000K，2400K，3900K等色温值与颜色增益值的对应关系。或者，拍摄终端还可建立预置间隔的色温值与颜色增益值的对应关系。如：若预置间隔为100K，起始色温值为2000K，截止色温值为8000K，则可建立的色温值与颜色增益值的对应关系可以是：建立色温值为2000K，2100K，2200K……8000K与颜色增益值的对应关系，其中，预置间隔还可是其他数值，在此不进行限制。用户可根据不同的色温值在拍摄终端上输入对应的颜色增益值，从而建立色温值与颜色增益的对应关系。In the embodiment of the present invention, the color gain value may include a red gain value R_gain and a blue gain value B_gain, and the color gain value may be used to adjust the output of the blue component or the red component of the picture. Wherein, the photographing terminal may establish a corresponding relationship between the color temperature value and the color gain value. Specifically, the photographing terminal may establish a correspondence between scattered and irregular color temperature values and color gain values, for example, establish a correspondence between color temperature values such as 2000K, 2400K, and 3900K and color gain values. Alternatively, the photographing terminal may also establish a correspondence between color temperature values and color gain values at preset intervals. For example: if the preset interval is 100K, the initial color temperature value is 2000K, and the cut-off color temperature value is 8000K, then the corresponding relationship between the color temperature value and the color gain value can be established as follows: the established color temperature value is 2000K, 2100K, 2200K...8000K The corresponding relationship with the color gain value, wherein, the preset interval may also be other numerical values, which is not limited here. The user can input the corresponding color gain value on the shooting terminal according to different color temperature values, so as to establish a corresponding relationship between the color temperature value and the color gain.
在本发明实施例中，当终端获取到目标色温值进行调整白平衡时，拍摄终端可首先判断拍摄终端是否有建立目标色温值与颜色增益值的对应关系，即拍摄终端可在建立的色温值与颜色增益值的对应关系中查询是否存储有该目标色温值与颜色增益值的对应关系。或者还可以是，当拍摄终端是建立预置间隔的色温值与颜色增益值的对应关系时，拍摄终端可判断目标色温值是否能够被预置间隔整除。当可以被预置间隔整除时，则可以在建立的色温值与颜色增益值的对应关系获取目标色温值对应的目标颜色增益值。当不可以被预置间隔整除时，拍摄终端可判断目标色温值的相邻的两个色温值C1和C2，其中，该色温值建立有色温值与颜色增益值的对应关系。从而拍摄终端可根据两个色温值C1和色温值C2获取色温值C1对应的颜色增益值为R_gain1和B_gain1，以及色温值C2对应的颜色增益值为R_gain2和B_gain2。进一步的，拍摄终端可获取色温值C1和色温值C2的权重，并根据权重以及色温值C1和色温值C2对应的颜色增益值R_gain1，B_gain1，R_gain2和B_gain2计算目标色温值对应的颜色增益值。具体的，可例如：当目标色温值Ct落在2400K和2500K的范围之间时，则色温值C1为2400K的权重W1＝(Ct-2400)/100，色温值C2为2500K的权重W2＝(2500-Ct)/100，目标色温值Ct的R_gainCt＝W1*R_gain1+W2*R_gain2，目标色温值Ct的B_gainCt＝W1*B_gain1+W2*B_gain2。从而获得目标色温值Ct的颜色增益值B_gainCt和R_gainCt。In the embodiment of the present invention, when the terminal acquires the target color temperature value to adjust the white balance, the shooting terminal can first determine whether the shooting terminal has established a corresponding relationship between the target color temperature value and the color gain value, that is, the shooting terminal can establish a color temperature value In the corresponding relationship with the color gain value, it is queried whether the corresponding relationship between the target color temperature value and the color gain value is stored. Alternatively, when the photographing terminal establishes the correspondence between the color temperature value and the color gain value at a preset interval, the photographing terminal may determine whether the target color temperature value is divisible by the preset interval. When it can be divisible by the preset interval, the target color gain value corresponding to the target color temperature value can be obtained from the established correspondence between the color temperature value and the color gain value. When not divisible by the preset interval, the photographing terminal can determine two adjacent color temperature values C1 and C2 of the target color temperature value, wherein the color temperature value establishes a corresponding relationship between the color temperature value and the color gain value. Therefore, the shooting terminal can obtain the color gain values R_gain1 and B_gain1 corresponding to the color temperature value C1 and the color gain values R_gain2 and B_gain2 corresponding to the color temperature value C2 according to the two color temperature values C1 and C2. Further, the shooting terminal can obtain the weights of the color temperature values C1 and C2, and calculate the color gain values corresponding to the target color temperature values according to the weights and the color gain values R_gain1, B_gain1, R_gain2 and B_gain2 corresponding to the color temperature values C1 and C2. Specifically, for example: when the target color temperature value Ct falls between 2400K and 2500K, the color temperature value C1 is 2400K weight W1=(Ct-2400)/100, and the color temperature value C2 is 2500K weight W2=( 2500-Ct)/100, R_gain Ct of the target color temperature value Ct =W1*R_gain1+W2*R_gain2, B_gain Ct of the target color temperature value Ct =W1*B_gain1+W2*B_gain2.

When the shooting device enters the white balance adjustment interface, the shooting device may display multiple white balance adjustment modes for the user to choose from, including an automatic adjustment mode, a preset environment mode, and a manual adjustment mode. When the user selects the manual adjustment mode, the photographing device can display a progress bar of the color temperature scale, so that the end user can select a desired color temperature value by operating the progress bar of the color temperature scale, so as to adjust the white balance of the photographing terminal.
在本发明实施例中，色温刻度进度条的范围可以进行预置，例如，色温刻度进度条的范围可以预置为0～7000K，或者色温刻度进度条的范围还可以预置为2500K～8000K等。可选的，色温刻度进度条的范围还可以由用户根据需要进行预置，在此不进行限制。进一步的，在本发明实施例中，色温刻度进度条还可包括预置间距的色温刻度以及滚动点。其中，色温刻度可如图2，色温刻度可设定为以预置间距100K为单位的小刻度，以预置间距1000K为单位的大刻度，小刻度和大刻度分别用不同的标记显示，其中大刻度的标记可更加醒目，如图2中在大刻度上标上色温值。滚动点在色温刻度进度条上的位置对应于色温值，终端用户可根据色温刻度进度条上显示的色温刻度，在色温刻度进度条上操作滚动点移动到所需的色温值相应的目标位置上，其中，操作滚动点动作还可以包括直接点击色温刻度进度条上的某一位置，例如当终端用户点击色温刻度进度条上的某一位置时，则表示终端用户将滚动点拖动至色温刻度进度条上的该位置上。其中，当滚动点被移动后，第一获取单元100可获取滚动点移动后的目标位置，例如：当终端用户拖动滚动点后并停止拖动时，第一获取单元100获取滚动点被拖动后直至停止时的目标位置。In the embodiment of the present invention, the range of the progress bar of the color temperature scale can be preset, for example, the range of the progress bar of the color temperature scale can be preset as 0-7000K, or the range of the progress bar of the color temperature scale can also be preset as 2500K-8000K, etc. . Optionally, the range of the progress bar of the color temperature scale can also be preset by the user according to needs, which is not limited here. Further, in the embodiment of the present invention, the progress bar of the color temperature scale may also include color temperature scales with preset intervals and scroll points. Among them, the color temperature scale can be shown in Figure 2. The color temperature scale can be set as a small scale with a preset interval of 100K as a unit, and a large scale with a preset interval of 1000K as a unit. The small scale and the large scale are displayed with different marks.

The position of the scroll point on the progress bar of the color temperature scale corresponds to the color temperature value. The end user can operate the scroll point on the progress bar of the color temperature scale to move to the target position corresponding to the required color temperature value according to the color temperature scale displayed on the progress bar of the color temperature scale. , where the action of operating the scroll point may also include directly clicking a certain position on the progress bar of the color temperature scale, for example, when the end user clicks a certain position on the progress bar of the color temperature scale, it means that the end user drags the scroll point to the color temperature scale at that position on the progress bar. Wherein, when the scroll point is moved, the first acquiring unit 100 can acquire the target position of the scroll point after moving, for example: when the terminal user drags the scroll point and stops dragging, the first acquiring unit 100 acquires the scroll point moved The target position after moving until stopping.
进一步的，拍摄终端还可通过摄像头获取当前外界光线的色温值，并根据外界光线的色温值控制色温刻度进度条上的滚动点移至外界光线的色温值对应的目标位置上，以方便终端用户从色温刻度进度条上读取当前外界光线的色温值。Further, the shooting terminal can also obtain the current color temperature value of the external light through the camera, and control the scroll point on the progress bar of the color temperature scale to move to the target position corresponding to the color temperature value of the external light according to the color temperature value of the external light, so as to facilitate the terminal user Read the current color temperature value of the external light from the progress bar of the color temperature scale.
进一步的，当拍摄终端通过摄像头获取当前外界光线的色温值时，拍摄终端可根据当前外界光线的色温值生成色温刻度进度条并显示色温刻度进度条，其中，该色温刻度进度条的色温刻度范围可以是以当前外界光线的色温值为中心，以间隔为预置间隔的数值为上下限值，如当前外界光线的色温值为Ct时，预置间隔为1000K时，则色温刻度范围可为(Ct-1000K，Ct+1000K)，如图3所示。从而使得终端用户可更精准地进行手动白平衡调整，获得终端用户所需的摄影作品。其中，终端用户可通过按键或屏幕操作选择终端是获取当前外界光线的色温值进行白平衡调整还是由用户进行手动输入色温值进行白平衡调整。Further, when the shooting terminal obtains the color temperature value of the current external light through the camera, the shooting terminal can generate a color temperature scale progress bar according to the current color temperature value of the external light and display the color temperature scale progress bar, wherein the color temperature scale range of the color temperature scale progress bar It can be centered on the color temperature value of the current external light, and the value of the preset interval is the upper and lower limit values. For example, when the color temperature value of the current external light is Ct and the preset interval is 1000K, the range of the color temperature scale can be ( Ct-1000K, Ct+1000K), as shown in Figure 3. Thus, end users can perform manual white balance adjustment more accurately, and obtain photographic works required by end users. Wherein, the terminal user can select whether the terminal obtains the color temperature value of the current external light to adjust the white balance or the user manually inputs the color temperature value to adjust the white balance through buttons or screen operations.
在本发明实施例中，拍摄终端可将色温刻度进度条上的每个色温值对应的每个滚动点的位置的对应关系存储在拍摄终端中。当获取到目标位置时，第二获取单元200可根据存储的滚动点的位置与色温值的对应关系，获取目标位置对应的目标色温值。In the embodiment of the present invention, the photographing terminal may store in the photographing terminal the correspondence between the positions of each scroll point corresponding to each color temperature value on the progress bar of the color temperature scale. When the target position is acquired, the second acquiring unit 200 may acquire the target color temperature value corresponding to the target position according to the stored correspondence between the position of the scroll point and the color temperature value.
在本发明实施例中，颜色增益值可包括红色增益值R_gain和蓝色增益值B_gain，该颜色增益值可用于调整图片的蓝色分量或红色分量的输出。其中，拍摄终端可建立色温值与颜色增益值的对应关系。具体的，拍摄终端可建立零散无规律的色温值与颜色增益值的对应关系，如，建立色温值为2000K，2400K，3900K等色温值与颜色增益值的对应关系。或者，拍摄终端还可建立预置间隔的色温值与颜色增益值的对应关系。如：若预置间隔为100K，起始色温值为2000K，截止色温值为8000K，则可建立的色温值与颜色增益值的对应关系可以是：建立色温值为2000K，2100K，2200K……8000K与颜色增益值的对应关系，其中，预置间隔还可是其他数值，在此不进行限制。用户可根据不同的色温值在拍摄终端上输入对应的颜色增益值，从而建立色温值与颜色增益的对应关系。In the embodiment of the present invention, the color gain value may include a red gain value R_gain and a blue gain value B_gain, and the color gain value may be used to adjust the output of the blue component or the red component of the picture. Wherein, the photographing terminal may establish a corresponding relationship between the color temperature value and the color gain value. Specifically, the photographing terminal may establish a correspondence between scattered and irregular color temperature values and color gain values, for example, establish a correspondence between color temperature values such as 2000K, 2400K, and 3900K and color gain values. Alternatively, the photographing terminal may also establish a correspondence between color temperature values and color gain values at preset intervals. For example: if the preset interval is 100K, the initial color temperature value is 2000K, and the cut-off color temperature value is 8000K, then the corresponding relationship between the color temperature value and the color gain value can be established as follows: the established color temperature value is 2000K, 2100K, 2200K...8000K The corresponding relationship with the color gain value, wherein, the preset interval may also be other numerical values, which is not limited here. The user can input the corresponding color gain value on the shooting terminal according to different color temperature values, so as to establish a corresponding relationship between the color temperature value and the color gain.
在本发明实施例中，当第二获取单元200获取到目标色温值进行调整白平衡时，第三获取单元300可首先判断拍摄终端是否有建立目标色温值与颜色增益值的对应关系，即第三获取单元300可在建立的色温值与颜色增益值的对应关系中查询是否存储有该目标色温值与颜色增益值的对应关系。或者还可以是，当拍摄终端是建立预置间隔的色温值与颜色增益值的对应关系时，第三获取单元300可判断目标色温值是否能够被预置间隔整除。当可以被预置间隔整除时，则第三获取单元300可以在建立的色温值与颜色增益值的对应关系获取目标色温值对应的目标颜色增益值。当不可以被预置间隔整除时，第三获取单元300可判断目标色温值的相邻的两个色温值C1和C2，其中，该色温值建立有色温值与颜色增益值的对应关系。从而第三获取单元300可根据两个色温值C1和色温值C2获取色温值C1对应的颜色增益值为R_gain1和B_gain1，以及色温值C2对应的颜色增益值为R_gain2和B_gain2。进一步的，第三获取单元300可获取色温值C1和色温值C2的权重，并根据权重以及色温值C1和色温值C2对应的颜色增益值R_gain1，B_gain1，R_gain2和B_gain2计算目标色温值对应的颜色增益值。具体的，可例如：当目标色温值Ct落在2400K和2500K的范围之间时，则第三获取单元300获得的色温值C1为2400K的权重W1＝(Ct-2400)/100，色温值C2为2500K的权重W2＝(2500-Ct)/100，目标色温值Ct的R_gainCt＝W1*R_gain1+W2*R_gain2，目标色温值Ct的B_gainCt＝W1*B_gain1+W2*B_gain2。从而第三获取单元300获得目标色温值Ct的颜色增益值B_gainCt和R_gainCt。In the embodiment of the present invention, when the second acquisition unit 200 acquires the target color temperature value to adjust the white balance, the third acquisition unit 300 may first determine whether the shooting terminal has established a corresponding relationship between the target color temperature value and the color gain value, that is, the first The third acquisition unit 300 may query whether the corresponding relationship between the target color temperature value and the color gain value is stored in the established corresponding relationship between the color temperature value and the color gain value. Alternatively, when the photographing terminal establishes a correspondence relationship between color temperature values at preset intervals and color gain values, the third acquiring unit 300 may determine whether the target color temperature value is divisible by the preset interval. When it can be divisible by the preset interval, the third acquiring unit 300 can acquire the target color gain value corresponding to the target color temperature value based on the established correspondence between the color temperature value and the color gain value. When not divisible by the preset interval, the third acquisition unit 300 can determine two adjacent color temperature values C1 and C2 of the target color temperature value, wherein the color temperature value establishes a corresponding relationship between the color temperature value and the color gain value. Therefore, the third acquiring unit 300 can acquire the color gain values R_gain1 and B_gain1 corresponding to the color temperature value C1 and the color gain values R_gain2 and B_gain2 corresponding to the color temperature value C2 according to the two color temperature values C1 and C2. Further, the third acquiring unit 300 can acquire the weights of the color temperature value C1 and the color temperature value C2, and calculate the color corresponding to the target color temperature value according to the weight and the color gain values R_gain1, B_gain1, R_gain2 and B_gain2 corresponding to the color temperature value C1 and the color temperature value C2 gain value. Specifically, for example: when the target color temperature value Ct falls between 2400K and 2500K, the color temperature value C1 obtained by the third acquisition unit 300 is the weight W1=(Ct-2400)/100 of 2400K, and the color temperature value C2 The weight W2=(2500-Ct)/100 of 2500K, the R_gain Ct of the target color temperature value Ct =W1*R_gain1+W2*R_gain2, the B_gain Ct of the target color temperature value Ct =W1*B_gain1+W2*B_gain2. Thus the third obtaining unit 300 obtains the color gain values B_gainCt and R_gainCt of the target color temperature value Ct.
调整单元400可将获得的目标颜色增益值的红色增益值和蓝色增益值分别作用在红色输出分量和蓝色输出分量上，从而完成白平衡调节。The adjustment unit 400 can apply the obtained red gain value and blue gain value of the target color gain value to the red output component and the blue output component respectively, so as to complete the white balance adjustment.
