    • An image sensor capable of ensuring high sensitivity image and minimizing color distortion is provided. The image sensor includes a first filter unit, a second filter unit formed at a lower part of the first filter unit and a sensor unit formed at a lower part of the second filter unit. The first filter unit is configured to pass light corresponding to a visible light region, pass light corresponding to a first region of a longer wavelength than the light corresponding to the visible region and cut off light corresponding to a second region of a longer wavelength than the light corresponding to the first region. The second filter unit is configure to pass light having a predetermined wavelength in a wavelength range corresponding to the visible light region among the light passing through the first filter unit and pass light corresponding to the first region. The sensor unit is configured to detect the light passing through the second filter unit.
    • 提供能够确保高灵敏度图像和最小化颜色失真的图像传感器。 图像传感器包括第一滤光器单元,形成在第一滤光单元的下部的第二滤光单元和形成在第二滤光单元下部的传感器单元。 第一滤光器单元被配置为通过对应于可见光区域的光,通过对应于比对应于可见光区域的光更长波长的第一区域的光,并且切断对应于比该可见光区域更长波长的第二区域的光 对应于第一区域的光。 第二滤光器单元被配置为在通过第一滤光器单元的光中通过在与可见光区域对应的波长范围中具有预定波长的光,并且通过对应于第一区域的光。 传感器单元被配置为检测通过第二过滤器单元的光。
