DEPTH SENSOR, METHOD OF CALCULATING DEPTH IN THE SAME

摘要

PURPOSE: A depth sensor and a depth calculating method thereof are provided to accurately measure depth even though at least one or more pixel signals are saturated. CONSTITUTION: A depth calculating method of a depth sensor outputs modulated lights to a target object (40). Four kinds of pixel signals are detected from the depth pixels according to reflected lights reflected by a target object. Whether the pixel signals are saturated or not is determined according to the result of comparison between the sizes and threshold values of the pixel signals. The depth to a target object is calculated according to the result of the determination.
