Color Mode
Color Mode可以设置控制如何计算彩色图像，可设置为以下几种模式：
ToneMappingUseFirstAcquisitionAutomatic
ToneMapping （色调映射）使用了所有采集项来生成一个融合的和标准化过的彩色图像。对于多次采集HDR捕获，得到的图像动态范围通常高于8位彩色图像范围。色调映射将通过应用比例因子将HDR颜色数据映射到8位颜色输出范围。色调映射也可用于单次采集捕获，以将捕获的彩色图像标准化为完整的8位输出。使用 ToneMapping 时，如果您移动、添加或移除了场景中的对象，重复捕获的颜色值可能会不一致。为了最大限度地控制颜色，请使用 UseFirstAcquisition 模式。
UseFirstAcquisition 使用了第一个采集项获得的颜色数据。如果捕获包含多次采集，则其它采集获得的数据不会被用于生成彩色图像。该模式下不会执行色调映射。此模式将提供对彩色图像的最大控制，并且颜色值将在使用相同设置的重复捕获中保持一致。
Automatic是默认设置。在进行单次采集和所有采集项都具有相同（重复的）采集设置的多次采集时，
Automatic等同于UseFirstAcquisition。在进行具有不同采集设置的多次采集HDR时，
Automatic等同于ToneMapping。
备注
从SDK 2.7开始，可以通过将颜色模式设置为 UseFirstAcquisition 来禁用HDR捕获的色调映射。
对于单次采集捕获，色调映射可用于使暗图像变明亮。

对于多次采集HDR，色调映射可用于将高动态范围颜色映射到更有限的动态范围输出。

使用UseFirstAcquisition的HDR捕获
如果您不想对多次采集HDR使用色调映射，而是使用其中一个采集项的彩色图像，这是可以实现的。确定您要使用哪个采集项中的颜色。然后，确保该采集项是HDR采集设置序列中的第一个，并将颜色模式设置为 UseFirstAcquisition 。对于上面的示例，现在生成的彩色图像看起来就像使用三个HDR采集中的第一个采集项的单次捕获的彩色图像。
提示
在Zivid Studio的采集设置中依次点击 … → Move to top 即可将选定的采集项移动到序列中的第一个位置。
如果要更改HDR捕获中获取彩色图像的采集项，只需重新排列采集设置即可。建议使用 UseFirstAcquisition 颜色模式以在重复捕获中保持颜色一致，这对诸如基于2D图像中的颜色或纹理的对象分类等应用非常有用。有关实现示例的详细说明，请查看 如何处理HDR中颜色不一致的问题。
