Claim 10:
11. A method of peeling tubers, the method comprising the steps of:
(a) providing a peeler device defining a cavity surrounded by a peeling mechanism;
(b) inputting tubers to be peeled into the cavity;
(c) directing electromagnetic radiation from an illumination device into the cavity;
(d) detecting electromagnetic radiation reflected into lens of a camera from tubers located in the cavity during a peeling operation by the peeling mechanism; and
(e) operating the peeler device based on the reflected electromagnetic radiation detected by the camera, wherein, operating step (e) comprises the sub-steps of;
i. sequentially measuring a plurality of intensity values of the detected electromagnetic radiation;
ii. comparing the measured intensity values to determining a rate of change of the measured intensity values; and
iii. controlling the peeler device in response to the rate of change of the measured intensity values.
