Abstract:
1. A solid-state image sensor comprising: a pixel array portion formed from a two-dimensional array of ordinary imaging pixels each having a photoelectric conversion unit and configured to output an electric signal obtained through photoelectric conversion as a pixel signal, and focus detection pixels for detecting focus, wherein the focus detection pixels include at least a first focus detection pixel and a second focus detection pixel each having a photoelectric conversion unit and configured to transfer and output an electric signal obtained through photoelectric conversion to an output node, wherein the first focus detection pixel and the second focus detection pixel share the output node, wherein the first focus detection pixel includes wherein the second focus detection pixel includes wherein the first transfer gate of the first focus detection pixel and the second transfer gate of the second focus detection pixel are electrically shared by a gate electrode to which a control signal for conduction control is applied.
