Self calibration of white balance for a digital camera device using correlated color temperature data
摘要：
This disclosure describes automatic self-calibration techniques for digital camera devices. In one aspect, a method for performing a calibration procedure in a digital camera device comprises initiating the calibration procedure when a camera sensor of the digital camera device is operating, accumulating data for the calibration procedure, the data comprising one or more averages of correlated color temperature (CCT) associated with information captured by the camera sensor, calculating one or more CCT vectors based on the one or more averages of CCT, and generating gray point correction factors based on the one or more CCT vectors.

本公开描述了用于数码相机设备的自动自校准技术。 一方面，一种用于在数字照相机装置中执行校准程序的方法包括当数字照相机装置的照相机传感器正在操作时，启动校准程序，累积用于校准过程的数据，该数据包括相关颜色的一个或多个平均值 温度（CCT），其与由摄像机传感器捕获的信息相关联，基于CCT的一个或多个平均值计算一个或多个CCT向量，以及基于一个或多个CCT向量生成灰点校正因子。
