    • An apparatus for performing shade correction for a lens in an image sensor includes a gain profile extractor, a common profile calculator, a gain controller calculator, and a memory device. The gain profile extractor generates a respective channel gain profile for each of a plurality of color channels from image data. The common profile calculator generates a common profile from the channel gain profiles. The gain controller calculator generates a respective gain controller for each of the plurality of color channels from the common profile and the channel gain profiles. A memory device stores the common profile and the gain controllers.
    • 用于对图像传感器中的透镜进行色调校正的装置包括增益轮廓提取器,公共轮廓计算器,增益控制器计算器和存储装置。 增益分布提取器从图像数据生成针对多个颜色通道中的每一个的相应的通道增益分布。 通用配置文件计算器从通道增益配置文件生成一个公共配置文件。 增益控制器计算器从公共简档和通道增益曲线生成针对多个颜色通道中的每一个的相应增益控制器。 存储器装置存储公共简档和增益控制器。

    • A biometric authentication system and apparatus are provided. The system includes an image capture device, a processor and an authentication unit. The image capture device generates first and second biometric data of a user based on reflected infrared light reflected from an object. The processor processes the first and second biometric data to generate first and second feature data. The first feature data is associated with the first biometric data, and the second feature data is associated with the second biometric data. The authentication unit performs authentication of the user based on at least one of the first feature data and the second feature data.
    • 提供了生物体认证系统和装置。 该系统包括图像捕获装置,处理器和认证单元。 图像捕获装置基于从对象反射的反射红外光产生用户的第一和第二生物统计数据。 处理器处理第一和第二生物特征数据以产生第一和第二特征数据。 第一特征数据与第一生物特征数据相关联,并且第二特征数据与第二生物特征数据相关联。 认证单元基于第一特征数据和第二特征数据中的至少一个来执行用户的认证。
