Image sensor capable of judging proximity of a subject

The present invention by allowing to determine the distance degree of, and more particularly, to an output voltage value changes by infrared or absence of a specific band wavelength to be measured by the optical sensor, such as proximity pixel subject relates to an image sensor, for normal image easy to implement features from the image sensor and proximity relates to the possible approaches for determining whether one be able to minimize the damage to the image quality when imaging the subject in measurement mode, night mode, or close the image sensor. An image sensor, whether close-up, close-pixel, the light emitting diodes, transmitted through the filter
