Summary:PROBLEM TO BE SOLVED: To provide a sensor assembly with a selective infrared filter array.SOLUTION: An image sensor includes both visible pixels and infrared pixels. The visible pixels produce signals indicative of light within a visible band received by the visible pixels, and the infrared pixels produce signals indicative of light within an infrared band received by the infrared pixels. A selective infrared (SIR) filter array is integrated on the image sensor. The SIR filter array includes SIR pixel filters that are positioned to filter out light within the infrared band propagating to the visible pixels. In this way, infrared crosstalk to the visible pixels can be reduced.SELECTED DRAWING: Figure 1A 【課題】本発明は、選択的赤外線フィルタアレイを有するセンサアセンブリを提供する。【解決手段】イメージセンサは、可視ピクセルおよび赤外線ピクセルをすべて含む。前記可視ピクセルは、前記可視ピクセルによって受信された可視帯域内の光を示す信号を生産し、前記赤外線ピクセルは、前記赤外線ピクセルによって受信された赤外線帯域内の光を示す信号を生産する。選択的赤外線(SIR)フィルタアレイは、前記イメージセンサ上に集積される。前記SIRフィルタアレイは、前記可視ピクセルに伝播する前記赤外線帯域内の光をフィルタリングするように配置されるSIRピクセルフィルタを含む。このような方式により、前記可視ピクセルに赤外線クロストークを減少させることができる。【選択図】図1A
