Claim 4:
5. A video system comprising an imaging device and a video processing device, wherein
the imaging device comprises:
an imaging unit configured to generate video data by imaging;
a front side NN unit comprising multiple layers of neural networks from an input layer to a predetermined intermediate hidden layer (hereinafter referred to as “intermediate hidden layer”) that are configured to perform recognition processing of the video data; and
an imaging side control unit configured to transmit an output of the intermediate hidden layer of the front side NN unit (hereinafter referred to as “intermediate feature quantity”), and

the video processing device comprises:
a video processing side control unit configured to acquire the intermediate feature quantity transmitted from the imaging side control unit; and
a rear side NN unit comprising the multiple layers of the neural networks from a layer subsequent the intermediate hidden layer to an output layer, the rear side NN unit configured to perform a remaining recognition processing regarding the intermediate feature quantity acquired by the video processing side control unit, and

the video processing device or an exterior thereof comprises:
an entire NN model configured to implement an entire node of the neural networks, and
an NN learning unit configured to perform a learning processing with respect to the entire NN model and determine a configuration parameter of each node of the entire NN model,

the imaging side control unit is configured to
acquire the configuration parameter corresponding to each node of the front side NN unit from the NN learning unit and set the same to each node of the front side NN unit, and

the video processing side control unit is configured to
acquire the configuration parameter corresponding to each node of the rear side NN unit from the NN learning unit and set the same to each node of the rear side NN unit.
