1. A balance and runout determining device for a rotary tool constituted by attaching a tool to a tool holder mounted on a spindle, the determining device comprising:
an image sensor for imaging the rotary tool; and
a calculating section for calculating a mass balance and a runout amount of the rotary tool based on the image obtained by the image sensor;
wherein in the course of rotation of the rotary tool as being mounted on the spindle, the calculating section obtains outer circumference position data of the rotary tool based on the obtained image, respectively for a case of adding a predetermined mass to a predetermined position of the tool holder and a case of not adding the predetermined mass to the predetermined position of the tool holder and determines a mass balance of the rotary tool from comparison between the outer circumference position data for the case of addition of the predetermined mass and the outer circumference position data for the case of no addition of the predetermined mass; and
wherein in the course of rotation of the rotary tool as being mounted on the spindle, the calculating section obtains shape data of the rotary tool based on the obtained image and calculates a runout amount of the rotary tool based on the shape data.
