一种确定对焦窗的方法、装置及设备制造方法及图纸

一种确定对焦窗的方法、装置及设备，用以解决采用爬山法容易导致失焦的问题，该方面包括：确定待拍摄图像中检测到人脸时，将人脸区域作为当前对焦窗；检测人脸区域中的预设位置，并根据人脸区域中的预设位置调整当前对焦窗的宽度；至少按照第一预设比例和第二预设比例拉伸当前对焦窗的长度；至少计算第一对焦窗内的图像的对比度值和第二对焦窗内的图像的对比度值；根据至少两个对比度值确定最终的对焦窗。因此，通过缩小对焦窗宽度，避免对焦窗出现背景内容，将对焦窗拉伸到人的身体部分，能够提升对焦窗内纹理丰富程度，进而有效提升人脸对焦过程中的对焦效果。

A method, device, and equipment for determining the focus window

A device and equipment determination method, focusing window, in order to solve the hill climbing method is easy to cause the defocus problem, comprising: determining shooting detected face images, the face region as the current focus detection window; the preset position in the face region, and according to the preset position adjustment face in the area of the width of the coke window; at least according to the first preset proportion and second of the proportion of preset tensile coke window length; at least the first comparison image of calculation of coke in the window of values and second focus window image value; according to at least two contrast values determine the final the focusing window. Therefore, by narrowing the width of the focal windows, avoiding the background contents of the focal windows, stretching the focal windows to the human body part, we can enhance the texture richness in the focal windows, and effectively enhance the focusing effect in the face focusing process.
