PROBLEM TO BE SOLVED: To provide technology advantageous in detecting infrared light with high SN ratio in a solid-state image device that can detect visible light and infrared light.SOLUTION: A solid-state image device is provided, which has a plurality of first pixels for detecting visible light and a plurality of second pixels for detecting infrared light. Each of the plurality of first pixels includes: a first filter that blocks infrared light and transmits visible light; and a first photoelectric conversion part that detects the visible light transmitted through the first filter. Each of the plurality of second pixels includes: a second filter that blocks visible light and transmits infrared light; and a second photoelectric conversion part that detects the infrared light transmitted through the second filter. The plurality of the second pixels are divided into a plurality of groups, each group having at least two second pixels. The solid-state image device includes a synthesis part that synthesizes a signal from signals of the at least two second pixels included in each group so as to output one signal in each group.SELECTED DRAWING: Figure 1 【課題】可視光および赤外光を検出可能な固体撮像装置において赤外光を高いＳＮ比で検出するために有利な技術を提供する。【解決手段】可視光を検出する複数の第１画素と、赤外光を検出する複数の第２画素とを有する固体撮像装置であって、前記複数の第１画素の各々は、赤外光を遮断し可視光を透過させる第１フィルタと、前記第１フィルタを透過した可視光を検出する第１光電変換部とを有し、前記複数の第２画素の各々は、可視光を遮断し赤外光を透過させる第２フィルタと、前記第２フィルタを透過した赤外光を検出する第２光電変換部とを有し、前記複数の第２画素は、それぞれ少なくとも２つの第２画素を含む複数のグループに分けられていて、前記固体撮像装置は、各グループについて１つの信号が出力されるように、各グループに含まれる前記少なくとも２つの第２画素の信号を合成する合成部を備える。【選択図】図１
