Abstract：In order to solve the problems of bit error in the data acquisition process caused by the asynchronous communication mode
of NanEye 2D miniature image sensor and the ±20% jitter of its own serial output clock, we designed and realized a customized
FPGA data acquisition IP core for the NanoEye 2D miniature image sensor. The IP core oversampled and acquired the camera image
signal by calling the dual edge sampling module in FPGA and using an adaptive and dynamic pulse width threshold adjustment
method. After being tested, the image data acquired by the IP core could be decoded an image similar to the real object by Bayer
decoding algorithm process on the host computer. The results showed that the IP core could accurately and stably capture the image
data of the camera. This design well solves the problem of bit error in the data acquisition process of NanEye 2D image sensor, which
will facilitate further development of medical applications based on NanEye 2D in the future.
