    • Disclosed is an image sensor for measuring illumination, proximity and color temperature, including: a light source unit configured to irradiate infrared with a wavelength of a specific band onto an object; a light source controller configured to control power supplied to the light source unit; an infrared transmission filter configured to allow only the infrared and visible ray with the wavelength of the specific band among light incident through a lens after being reflected by the object to selectively transmit therethrough; a first sensing unit provided with an image pixel for acquiring an image of the object introduced through the infrared transmission filter; and a second sensing unit configured to receive the infrared and the visible ray having passed through the infrared transmission filter and measure current illumination, proximity to the object and color temperature of the object.
    • 公开了一种用于测量照明,接近度和色温的图像传感器,包括:光源单元,被配置为将具有特定波段的波长的红外线照射到物体上; 光源控制器,被配置为控制提供给所述光源单元的电力; 红外线透射滤光器,其被配置为仅在被物体反射后仅允许通过透镜入射的光中的特定波段的红外线和可见光线从而选择性地透射; 第一感测单元,设置有用于获取通过红外线透射滤光器引入的物体的图像的图像像素; 以及第二感测单元,被配置为接收已经穿过红外线透射滤光器的红外线和可见光,并且测量当前照明,物体的接近度和物体的色温。
