Image sensor for measuring illumination, proximity and color temperature

摘要

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 Lhe 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.
