摄像头的工作原理大致为：景物通过镜头（LENS）生成的光学图像投射到图像传感器表面上，然后转为电信号，经过A/D（模数转换）转换后变为数字图像信号，再送到数字信号处理芯片（DSP）中加工处理，再通过USB接口传输到电脑中处理，通过显示器就可以看到图像了。 -The working principle of the camera more or less as follows: the scene through the lens (LENS) to generate the optical image projected onto the image sensor surface, and then converted to electrical signals, after A/D (analog-digital conversion) converted into a digital image signal, and then sent to digital signal processing chip (DSP) in the processing, transmission through the USB interface to computer processing, through the display can be seen on the images.
