IMAGE SENSOR CAPABLE OF MEASUREMENT FOR ILLUMINANCE, PROXIMITY AND COLOR TEMPERATURE

摘要

PURPOSE: An image sensor capable of measuring for illuminance, proximity, and color temperature of an object by installing a second sensing unit around a first sensing unit and separately operating the second sensing unit from the first one. CONSTITUTION: A light source(110) project infrared ray having a certain wavelength on an object. A light source control part(120) controls power supplied to the light source. A first sensing unit(160) includes an image pixel getting the image of the object which is projected through an infrared ray filter. An illumination detector receives external light passed through the infrared ray filter and measures the illuminance of the object.
