Solid-state imaging element, signal processing method thereof, and electronic device

A signal processing method, comprising:

• executing a calculation, by a solid-state imaging element, of at least one stage of a convolutional layer and a pooling layer in a convolutional neural network, on a signal corresponding to a light reception amount of light incident on each pixel of a pixel array unit;
• changing, by the solid-state imaging element, based on a coefficient corresponding to the calculation of the convolutional layer, a capacity ratio of a capacitive element configured to hold the signal different for each pixel of the pixel array unit;
• and
• multiplying, by the solid-state imaging element, the signal by the coefficient corresponding to the calculation of the convolutional layer based on the changed capacity ratio of the capacitive element;
• and
• outputting, by the solid-state imaging element, a pixel signal based on the calculation.
