Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings.
[0019] See attached figure 1 And attached image 3 In the present invention, a start command is issued by the DSP, and the command instruction is transmitted to the FPGA chip through the network port. This command command contains the start information and the integration time of the demand detector. The network port module adopts TCP / IP protocol, and under the hardware support of the present invention, the transmission rate can be as high as 50Mbps.
[0020] After the FPGA receives the start command, it generates the corresponding driving sequence and sends it to the image sensor LUPA4000 through the I / O interface of the FPGA. After the image sensor LUPA4000 receives the corresponding driving sequence, the photosensitive surface is exposed, and the sensor completes the photoelectric conversion through two steps of integration and data readout, and outputs the analo...
