Abstract: An image sensor is capable of judging proximity to a subject. The image sensor judges the distance to the subject using a change in output voltage value by the presence or absence of a specific band of wavelengths of infrared (IR) measured by optical sensors such as proximity pixels. Thereby, the image sensor enables an ordinary image sensor to easily realize a proximity function, and makes it possible to minimize damage to a quality of image when the image is picked up in a night photography mode or in a proximity photography mode.
