The invention discloses a CIS (Contact Image Sensor) image data noise reduction method, which comprises the following steps of: collecting night video image data by a CIS sensor, and carrying out median filtering processing on the night video image data; dividing the processed night video image data into a training set, a verification set and a test set; constructing a deep convolutional neural network, normalizing the processed data in the training set, and training the deep convolutional neural network; evaluating the training model by using the obtained test set and adopting a peak signal-to-noise ratio (PSNR); inputting the obtained verification set into a training model for processing and evaluation, and adjusting the number of network layers and the number of filters according to an evaluation result to obtain an optimal deep convolutional neural network model; and carrying out noise reduction processing on the CIS image data by using the obtained optimal deep convolutional neural network model to obtain image data after noise reduction. The method has the advantages of improving the noise reduction effect, increasing the video processing speed and the like.
