Abstract
The present technology relates to a solid-state image sensor, an imaging device, and electronic equipment configured such that an FD is shared by a plurality of pixels to further miniaturize the pixels at low cost without lowering of sensitivity and a conversion efficiency. In a configuration in which a plurality of pixels are arranged with respect to at least either of one of the OCCFs or one of the OCLs, a floating diffusion (FD) is shared by a sharing unit including a plurality of pixels, the plurality of pixels including pixels of at least either of different OCCFs or different OCLs. The present technology is applicable to a CMOS image sensor.
