Embodiment Construction
[0034] The steps included in the present invention will be described in detail below in combination with the technical solution of the present invention and the accompanying drawings.
[0035] Step 1, CMOS image sensor circuit connection
[0036]The FPGA of Xilinx Company writes the set parameters into the register of the CMOS image sensor through the SCLK clock and SDATA data signal of the IIC bus. Including settings such as working mode, image and gain size. FPGA also provides the main input clock EXTCLK of 12.5MHz to the sensor, and then the pixel clock PIXCLK of 96MHz is multiplied by the on-chip phase-locked loop of the sensor. The FPGA also provides an exposure trigger signal TRIGGER to control the image frame rate. Whenever TRIGGER is at a low level, a frame of image will be triggered, and the length of the low level time determines the length of the exposure time. The image sensor transmits the output image data DOUT, the output pixel clock PIXCLK, the frame valid si...
