Abstract: For a solid-state imaging element that executes image recognition processing, versatility is improved. The solid-state imaging element includes a processing section, a digital signal processing section, and an output interface. The processing section selects any one of a plurality of DNNs (Deep Neural Networks) with different formats of an output tensor. The digital signal processing section executes image recognition processing on an input tensor by use of the selected DNN to generate the output tensor. The output interface outputs a decode parameter for decoding the generated output tensor and the output tensor.
