IMAGE SENSOR FOR SENSING OBJECT DISTANCE INFORMATION

摘要

PURPOSE: An image sensor capable of sensing distance information is provided to perform an interpolation process by determining the distance using two clock signals. CONSTITUTION: A clock signal generator(120) creates a first to a fourth clock signals. A plurality of pixels creates distance signals through a light reflected from a target object or the clock signal of the first to fourth clock signals. A distance information determination unit(130) determines the distance information about the object through distance signals. An interpolation unit(140) interpolates the distance information of each pixel through the distance information of the adjacent pixels.
