Patent ID: 8531528

Claim:
An image sensor capable of realizing night-photographing and functions of a proximity sensor and an illuminance sensor, comprising: a light source for emitting light toward a subject; a light source control section for controlling current applied to the light source; an illuminance sensor section for sensing an illuminance of surrounding environment; and a sensor section having an image sensor unit for sensing an image signal wherein the illuminance sensor section comprises illuminance sensors and red pixels which are arranged adjacent to both ends of the image sensor unit, wherein the illuminance sensor section comprises illuminance sensors and blue pixels which are arranged adjacent to both ends of the image sensor unit, wherein the red pixels are used to calculate a distance between the red pixels and the subject using a difference between voltage values respectively outputted when the light source is turned on and off, and wherein the blue pixels are used to calculate a distance between the blue pixels and the subject using a difference between voltage values respectively outputted when the light source is turned on and off.
