The present disclosure relates to a solid-state imaging apparatus and electronic equipment that can reduce power consumption. In an AD converter for each unit pixel or each shared pixel unit, a pixel signal is compared with a reference signal temporally changing. In addition, a magnitude of a pixel signal of a pixel of interest is compared with a magnitude of each of pixel signals of neighboring pixels located in a neighborhood of the pixel of interest using the reference signal, and a result of comparison of the magnitudes is held in a data storage section. The present disclosure can be applied to a back-illuminated solid-state imaging apparatus, for example.
