    • A human face recognition method and apparatus are provided. A processor of the human face recognition apparatus calculates red, green, and blue component statistic information for each of a plurality of human face images. The processor uses an independent component analysis algorithm to analyze component statistic information of two colors and derive a piece of first component information and a piece of second component information. The processor transforms the pieces of first component information and second component information into a frequency domain to derive a piece of first frequency-domain information and a piece of second frequency-domain information. The processor calculates an energy value of the first frequency-domain information within a frequency range. The energy value is used to decide whether the human face images are captured from a human being.
    • 提供人脸识别方法和装置。 人脸识别装置的处理器针对多个人脸图像中的每一个计算红,绿和蓝分量统计信息。 处理器使用独立的分量分析算法来分析两种颜色的分量统计信息,并得到一条第一分量信息和一条第二分量信息。 处理器将第一分量信息和第二分量信息转换成频域以导出一段第一频域信息和一条第二频域信息。 处理器计算频率范围内的第一频域信息的能量值。 能量值用于确定人脸图像是否从人类获取。

    • An exemplary image stabilizer includes a shaking sensor, a control module, a driving module, an image module, and a data adjusting module. The shaking sensor detects a shake of a lens associated with the image stabilizer. The control module stores a shake correcting setting having one or more error ranges. The driving module is controlled by the control module to move the lens according to the shake correcting setting. The image module captures an image through the corrected lens. The data adjusting module adjusts the shake correcting setting within one or more of the error ranges when a resolution value of the captured image is lower than a preset reference value.
    • 示例性的图像稳定器包括摇动传感器,控制模块,驱动模块,图像模块和数据调整模块。 摇动传感器检测与图像稳定器相关联的镜头的抖动。 控制模块存储具有一个或多个误差范围的抖动校正设置。 驱动模块由控制模块控制,以根据抖动校正设置移动镜头。 图像模块通过校正的镜头捕获图像。 当捕获图像的分辨率值低于预设参考值时,数据调整模块在一个或多个误差范围内调整抖动校正设置。

    • An auto-focusing camera module includes a lens module, an image sensor, a color separation unit, a controller, and a shape memory alloy. The lens module captures light signal of an object. The image sensor senses the light and forms an image. The color separation unit separates the image into red image, green image and blue image. The controller calculates MTF values of the image and determines a shooting distance between the lens module and the object. When the shooting distance is greater than a predetermined distance value, the controller processes the image according to the MTF values to compensate blurs of the image caused by out of focus; when the shooting distance is equal to or less than the predetermined distance value, the controller controls the shape memory alloy drive the lens module to an optimum focusing position for focus according to the MTF values.
    • 自动聚焦照相机模块包括透镜模块,图像传感器,分色单元,控制器和形状记忆合金。 镜头模块捕获物体的光信号。 图像传感器感测光并形成图像。 分色单元将图像分成红色图像,绿色图像和蓝色图像。 控制器计算图像的MTF值,并确定镜头模块和物体之间的拍摄距离。 当拍摄距离大于预定距离值时,控制器根据MTF值对图像进行处理,以补偿由焦点造成的图像模糊; 当拍摄距离等于或小于预定距离值时,控制器根据MTF值控制形状记忆合金将透镜模块驱动到用于聚焦的最佳聚焦位置。
