Abstract: A time of flight (ToF) measuring apparatus and an image processing method for reducing blur of a depth image in the ToF measuring apparatus are provided. The apparatus senses infrared (IR) light reflected by a subject and incident via an optical shutter, models a spread characteristic of the IR light based on an intensity distribution of the sensed IR light, and acquires a sharpening filter by using the modeled spread characteristic.
